Description

[0001] This application claims the priority of a Chinese patent application titled "An Electronic Device" with an application number of 202311840097.2 and filed with the Chinese Patent Office on December 27, 2023, as well as a Chinese patent application titled "An Electronic Device" with an application number of 202410544898.2 and filed with the Chinese Patent Office on April 28, 2024. The entire content of which is incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication, and in particular, to an electronic device. Background Art

[0003] Currently, in existing terminal electronic devices, the frame is used as an antenna radiator. For example, in a satellite communication system, the frame radiator is mainly used to form a linearly polarized antenna. When a user conducts satellite communication, it is necessary to point the area where the antenna has good radiation characteristics (for example, the gain of the antenna in this area is greater than or equal to AdBic, and A is the minimum gain value that meets the communication requirements in this satellite communication system) at the satellite to achieve satellite pointing (establish a communication connection with the satellite).

[0004] However, during satellite communication, the relative position between the electronic device and the satellite changes. For example, for a low-earth orbit satellite moving, the satellite may go beyond the area where the antenna has good radiation characteristics. In this case, it is necessary for the user to change the holding posture or move so that the satellite remains in the area where the antenna has good radiation characteristics to maintain the satellite pointing state or establish a connection with a new satellite, otherwise, it will cause problems such as poor communication quality or even disconnection, which greatly affects the user's communication experience. Summary of the Invention

[0005] This application provides an electronic device, which includes a first antenna and a second antenna. The operating frequency bands of the first antenna and the second antenna include the satellite communication frequency band. The first antenna and the second antenna can generate different maximum radiation directions. The electronic device can switch between the first antenna and the second antenna for satellite communication, or, simultaneously conduct satellite communication with the first antenna and the second antenna, which can improve the user experience during satellite communication.

[0006] In a first aspect, an electronic device is provided, including: a floor; a first frame, the first frame including a first position, a second position, a third position, and a fourth position arranged in sequence, the first frame being coupled to the floor or having an insulating gap at the first position, the first frame being coupled to the floor or having an insulating gap at the second position, the first frame being coupled to the floor or having an insulating gap at the third position, the first frame being coupled to the floor or having an insulating gap at the fourth position, the first frame including a first side and a second side intersecting at an angle, the length of the first side being less than the length of the second side, the first position and the second position being located on the first side, and the third position and the fourth position being located on the second side; a first antenna, the first antenna including: a first radiator, the first radiator including a conductive portion of the first frame between the first position and the second position, at least a portion of the first radiator being spaced apart from the floor, and a first feeding circuit, the first radiator including a first feeding point, the first feeding circuit being coupled to the first feeding point, the first feeding circuit being for radio frequency signals in a satellite communication band; a second antenna, the second antenna including: a second radiator, the second radiator including a conductive portion of the first frame between the third position and the fourth position, at least a portion of the second radiator being spaced apart from the floor, and a second feeding circuit, the second radiator including a second feeding point, the second feeding circuit being coupled to the second feeding point, the second feeding circuit being for transmitting radio frequency signals in the satellite communication band; wherein, a first radiation pattern generated by the first antenna and a second radiation pattern generated by the second antenna are different, and the electronic device performs satellite communication in the satellite communication band through at least one of the first antenna or the second antenna.

[0007] According to an embodiment of the present application, since the first radiator is located on the short side (e.g., the top side) of the electronic device and the second radiator is located on the side of the electronic device. Therefore, the first antenna can generate better radiation in the top direction and has better radiation characteristics. The second antenna can be used to improve the radiation of the electronic device in the upper hemisphere region. For example, the second antenna can be used to enhance the radiation of the electronic device in the top direction towards the side of the second radiator, and the electronic device can have good communication characteristics within a larger angular range with respect to the top direction. Among them, the upper hemisphere region can be understood as the region within an angle less than or equal to 90° with respect to the top direction. In the coordinate system, it can be understood as the region where the xoy plane faces the positive direction of the z direction.

[0008] In combination with the first aspect, in some implementation manners of the first aspect, the first frame has a first insulating gap and a second insulating gap at the first position and the second position respectively.

[0009] According to the embodiments of the present application, the resonance generated by the first radiator is generated by the line DM mode. The pattern generated by the line DM mode has no strong flowing current to the floor. Therefore, less current is excited on the floor, and the influence of the floor on the pattern generated by the line DM mode is similar to that of a reflector. Thus, the pattern generated by the line DM mode is mainly oriented towards the top direction of the electronic device (the direction away from the floor of the first radiator, for example, the z direction). For the pattern generated by the line CM mode, since the current flowing to the floor in the line CM mode is strong, more current is excited on the floor, and the floor has a great influence on the pattern generated by the antenna. Therefore, the pattern generated by the line CM mode is not mainly oriented towards the top direction of the electronic device (the direction away from the floor of the first radiator 310, for example, the z direction).

[0010] Moreover, in the satellite communication frequency band, the efficiency (e.g., radiation efficiency) of the antenna generating resonance by the line DM mode can meet the requirements of satellite communication. For example, when the first radiator extends linearly, under the action of the co-directional current, both the conductor loss and the dielectric loss are small, so the efficiency (e.g., radiation efficiency) of the first antenna is high. However, for the line CM mode, since the current on the radiator is reversed and the loss is large, the efficiency (e.g., radiation efficiency) of the antenna generating resonance by the line CM mode is poor.

[0011] In combination with the first aspect, in some implementation manners of the first aspect, the first antenna further includes: a first tuning circuit. The first radiator includes a first connection point. The first tuning circuit is coupled to the first connection point. The first connection point and the first feeding point are respectively located on both sides of the first virtual axis of the first radiator, and the lengths of the first radiator on both sides of the first virtual axis are the same.

[0012] According to the embodiments of the present application, the first tuning circuit can be used to switch the resonance point frequency at which the first antenna generates resonance, so that the operating frequency band of the first antenna includes different communication frequency bands at different times / periods.

[0013] In combination with the first aspect, in some implementation manners of the first aspect, the first tuning circuit further includes: a first switch branch, a second switch branch, and a first switch; wherein, the first switch branch and the second switch branch are coupled and connected between the first connection point and the floor through the first switch.

[0014] According to the embodiments of the present application, the first switch branch and the second switch branch can be used to adjust the current distribution on the floor, so as to deflect the first pattern generated by the first antenna.

[0015] In combination with the first aspect, in some implementations of the first aspect, based on the coupling of the first connection point to the first switch branch, the first radiator is configured to generate a first resonance; based on the coupling of the first connection point to the second switch branch, the first radiator is configured to generate a second resonance; wherein, the resonance frequency band of the first resonance and the resonance frequency band of the second resonance both include the satellite communication frequency band.

[0016] According to an embodiment of the present application, when the first connection point is coupled to the first switch branch or the second switch branch through the first switch, the resonance frequency band of the resonance generated by the first radiator can include the same satellite communication frequency band.

[0017] In combination with the first aspect, in some implementations of the first aspect, the first frame further includes a first grounding point between the first position and the second position, and the first frame is coupled to the ground plane at the first grounding point; based on the coupling of the first connection point to the first switch branch, the first radiator is further configured to generate a third resonance, and there is a first frequency difference between the resonance point frequency of the first resonance and the resonance point frequency of the third resonance; based on the coupling of the first connection point to the second switch branch, the first radiator is further configured to generate a fourth resonance, and there is a second frequency difference between the resonance point frequency of the second resonance and the resonance point frequency of the fourth resonance, and the frequency difference between the second frequency difference and the first frequency difference is greater than or equal to 50 MHz.

[0018] According to an embodiment of the present application, when the difference between the first frequency difference and the second frequency difference is within the above range, when the first connection point is coupled to the first switch branch or the second switch branch respectively, the current on the ground plane on the first side of the virtual axis is more different from the current on the ground plane on the second side of the virtual axis, so that the difference between the first radiation pattern and the second radiation pattern is greater (for example, the angle between the maximum radiation directions increases), and the width of the radiation beam of the first antenna can be further broadened. The first antenna has a wider beam width, enabling the first antenna to have good communication characteristics within a wider angle (the angle with respect to the top direction) range.

[0019] In combination with the first aspect, in some implementations of the first aspect, based on the coupling of the first connection point to the first switch branch, the current on the ground plane on the first side of the virtual axis is greater than the current on the ground plane on the second side of the virtual axis; based on the coupling of the first connection point to the second switch branch, the current on the ground plane on the first side of the virtual axis is less than the current on the ground plane on the second side of the virtual axis.

[0020] In combination with the first aspect, in some implementations of the first aspect, the length of the first frame between the first feeding point and the third position is less than the length of the first frame between the first connection point and the third position.

[0021] According to the embodiments of the present application, the first feeding point may be located on a side close to the second antenna. In one embodiment, the first feeding circuit and the second feeding circuit may be generated by different radio frequency channels of the same radio frequency chip. When the first feeding point is close to the second feeding point, the current transmission paths from the radio frequency chip to the first feeding point and the second feeding point are shorter, which can reduce the loss caused by line transmission and improve the radiation characteristics of the antenna.

[0022] Moreover, since the area near the feeding point usually has a strong current, when the first feeding point can be located on a side close to the second antenna, it is easier to enhance the current on the floor on the second side of the virtual axis, causing the maximum radiation direction of the radiation pattern generated by the first antenna to deflect away from the second antenna side, making the difference between the radiation patterns of the first antenna and the second antenna larger, so that the electronic device has good communication characteristics within a wider angle (the angle formed with the top direction) range.

[0023] In combination with the first aspect, in some implementation manners of the first aspect, the first frame further includes a first grounding point between the first position and the second position, and the first frame is coupled to the floor at the first grounding point; wherein, the first radiator is used to generate a first resonance and a second resonance, and the resonance point frequency of the second resonance is lower than the resonance point frequency of the first resonance; wherein, the ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance is less than or equal to 1.3; the center frequency of the satellite communication frequency band is greater than the resonance point frequency of the second resonance and less than the resonance frequency of the first resonance.

[0024] According to the embodiments of the present application, in the first frequency band (or the second frequency band), the first antenna may operate in a hybrid mode of the line CM mode and the line DM mode, and radiation is jointly generated by the line CM mode and the line DM mode. The first antenna simultaneously has partial radiation characteristics of the line CM mode and partial radiation characteristics of the line DM mode.

[0025] In combination with the first aspect, in some implementation manners of the first aspect, the length of the first radiator between the first grounding point and the first position is greater than or equal to one quarter of the length of the first radiator, and the length of the first radiator between the first grounding point and the second position is greater than or equal to one quarter of the length of the first radiator.

[0026] According to the embodiments of the present application, the first grounding point may be set in a region close to the center of the first radiator to better excite the first radiator to generate the line CM mode and the line DM mode. And when the first grounding point can be set in a region close to the center of the first radiator, it is more convenient to adjust the frequency difference between the resonances generated by the line CM mode and the line DM mode, making the first antenna have better radiation characteristics.

[0027] In combination with the first aspect, in some implementations of the first aspect, the first antenna further includes a first element. The first radiator includes a second connection point and a third connection point. The first radiator has a third insulating gap between the second connection point and the third connection point. The first element is coupled between the second connection point and the third connection point. Wherein, the first frame has a first insulating gap at the first position, the first frame is coupled to the floor at the second position, or, the first frame is coupled to the floor at the first position, and the first frame has a second insulating gap at the second position.

[0028] According to the embodiments of the present application, the first radiator has a structure with one end being a grounding end and the other end being an open end. Moreover, the first radiator having a third insulating gap can be regarded as an equivalent capacitance (such as distributed capacitance) provided on the first radiator. This equivalent capacitance can enable the first radiator to form a meta material structure. The first radiator with this meta material structure can increase the radiation aperture, and after having this fifth insulating gap, the electric field is more dispersed. In one embodiment, the dielectric loss near the first radiator forming the meta material structure is reduced, so the radiation characteristics of the first antenna (such as system efficiency and radiation efficiency) can be effectively improved.

[0029] Moreover, by the first element coupled between the first connection point and the second connection point, the equivalent capacitance value of the fifth insulating gap can be adjusted, thereby adjusting the radiation characteristics of the first antenna (such as the resonant point frequency of the first resonance generated by the first radiator).

[0030] In combination with the first aspect, in some implementations of the first aspect, based on the first frame having a first insulating gap at the first position and the first frame being coupled to the floor at the second position, the length of the first radiation between the second position and the third insulating gap is less than the length of the first radiator between the first position and the third insulating gap, or, based on the first frame being coupled to the floor at the first position and the first frame having a second insulating gap at the second position, the length of the first radiation between the second position and the third insulating gap is greater than the length of the first radiator between the first position and the third insulating gap.

[0031] In combination with the first aspect, in some implementations of the first aspect, the first frame has a fourth insulating gap at the third position, the first frame is coupled to the floor at the fourth position, or, the first frame is coupled to the floor at the third position, and the first frame has a fifth insulating gap at the fourth position.

[0032] According to an embodiment of the present application, the second radiator has a structure with one end being the ground end and the other end being the open end. The second radiator can form a structure similar to an inverted-F antenna or a left-handed antenna structure.

[0033] In combination with the first aspect, in some implementation manners of the first aspect, the second antenna further includes a second element; the second radiator includes a fourth connection point and a fifth connection point, and the second radiator has a sixth insulating gap between the fourth connection point and the fifth connection point, and the second element is coupled between the fourth connection point and the fifth connection point. Wherein, the first frame has a fourth insulating gap at the third position, and the first frame is coupled to the floor at the fourth position, or, the first frame is coupled to the floor at the third position, and the first frame has a fifth insulating gap at the fourth position.

[0034] According to an embodiment of the present application, the second radiator has a structure with one end being the ground end and the other end being the open end. Moreover, the second radiator having a sixth insulating gap can be regarded as an equivalent capacitance (such as a distributed capacitance) provided on the second radiator, and this equivalent capacitance can enable the second radiator to form a metamaterial structure.

[0035] In combination with the first aspect, in some implementation manners of the first aspect, based on the first frame having a fourth insulating gap at the third position and the first frame being coupled to the floor at the fourth position, the length of the second radiation between the fourth position and the sixth insulating gap is less than the length of the second radiator between the third position and the sixth insulating gap, or, based on the first frame being coupled to the floor at the third position and the first frame having a fifth insulating gap at the fourth position, the length of the second radiation between the fourth position and the sixth insulating gap is greater than the length of the second radiator between the third position and the sixth insulating gap.

[0036] In combination with the first aspect, in some implementation manners of the first aspect, the first frame has a fourth insulating gap and a fifth insulating gap at the third position and the fourth position respectively.

[0037] According to an embodiment of the present application, the resonance generated by the second radiator is generated by the line DM mode. The pattern generated by the line DM mode has no strong flow to the floor current. Therefore, less current is excited on the floor, and the influence of the floor on the pattern generated by the line DM mode is similar to that of a reflector. Thus, the pattern generated by the line DM mode is mainly oriented towards the top direction of the electronic device (the direction in which the first radiator is away from the floor, e.g., the z direction). For the pattern generated by the line CM mode, since the current flowing to the floor in the line CM mode is strong, more current is excited on the floor, and the floor has a great influence on the pattern generated by the antenna. Thus, the pattern generated by the line CM mode is not mainly oriented towards the top direction of the electronic device (the direction in which the first radiator 310 is away from the floor, e.g., the z direction).

[0038] In combination with the first aspect, in some implementation manners of the first aspect, the second antenna further includes: a second tuning circuit, the second radiator includes a second connection point, the second tuning circuit is coupled to the second connection point, the second connection point and the second feeding point are respectively located on both sides of the second virtual axis of the second radiator, and the lengths of the second radiators on both sides of the second virtual axis are the same.

[0039] According to an embodiment of the present application, the second tuning circuit can be used to switch the resonant point frequency of the resonance generated by the second antenna, so that the operating frequency band of the second antenna includes different communication frequency bands at different times / periods.

[0040] In combination with the first aspect, in some implementation manners of the first aspect, the first frame further includes a second grounding point between the third position and the fourth position, and the first frame is coupled to the floor at the second grounding point.

[0041] In combination with the first aspect, in some implementation manners of the first aspect, the second radiator is used to generate a fifth resonance and a sixth resonance, and the resonant point frequency of the sixth resonance is lower than the resonant point frequency of the fifth resonance; wherein, the ratio between the resonant point frequency of the fifth resonance and the resonant point frequency of the sixth resonance is less than or equal to 1.3; the center frequency of the satellite communication frequency band is less than the resonant point frequency of the fifth resonance and greater than the resonant frequency of the sixth resonance.

[0042] According to an embodiment of the present application, in the first frequency band (or the second frequency band), the second antenna can operate in a hybrid mode of the line CM mode and the line DM mode, and radiation is jointly generated by the line CM mode and the line DM mode. The second antenna simultaneously has partial radiation characteristics of the line CM mode and partial radiation characteristics of the line DM mode.

[0043] In connection with the first aspect, in certain implementations of the first aspect, the electronic device further includes a first housing, a second housing, and a first rotating shaft. The first rotating shaft is located between the first housing and the second housing, and the first rotating shaft is rotatably connected to the first housing and the second housing respectively; wherein, the first housing includes the first frame.

[0044] In connection with the first aspect, in certain implementations of the first aspect, the minimum distance between the second radiator and the first radiator in the extending direction of the second side is greater than or equal to 20 mm and less than or equal to one half of the length of the second side.

[0045] According to the embodiments of the present application, the first radiator and / or the second radiator may be located in the upper half (the area near the top) of the electronic device, which is more conducive to the radiation generated by the first antenna and / or the second antenna in the top direction, so that the electronic device has good communication quality with the communication satellite.

[0048] In connection with the first aspect, in certain implementations of the first aspect, at a first time, the electronic device performs satellite communication in the first frequency band by the first antenna, at a second time, the electronic device performs satellite communication in the first frequency band by the second antenna, or, at the first time, the electronic device performs satellite communication in the first frequency band by the first antenna and the second antenna respectively.

[0049] In connection with the first aspect, in certain implementations of the first aspect, at a third time, the electronic device performs satellite communication in the second frequency band by the first antenna, at a fourth time, the electronic device performs satellite communication in the second frequency band by the second antenna, or, at the third time, the electronic device performs satellite communication in the second frequency band by the first antenna and the second antenna respectively.

[0050] In connection with the first aspect, in certain implementations of the first aspect, the second antenna is used to improve the radiation characteristics of the electronic device in the upper hemisphere region; wherein, the upper hemisphere region is the region within an angle less than or equal to 90° with respect to the top direction, and the top direction is perpendicular to the first side and points from the inside of the electronic device to the first side.

[0177] Hereinafter, the terms that may appear in the embodiments of the present application will be explained.

[0178] It should be understood that the term "and / or" used herein is merely a description of the same field of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this text generally indicates that the associated objects before and after are in an "or" relationship.

[0179] For the use of "within... range" in this application, unless it is separately specified that the end values are not included, it is default to include the two end values of the range. For example, within the range of 1 to 5, the two numerical values 1 and 5 are included.

[0180] Coupling: It can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as direct coupled connection and / or indirect coupled connection. Direct coupling can also be referred to as "electrical connection", which is understood as the physical contact and electrical conduction of components; it can also be understood as a form of connection between different components in a circuit structure through physical lines such as copper foils or wires of a printed circuit board (PCB) that can transmit signals. "Indirect coupling" can be understood as the electrical conduction of two conductors in a non-contact manner through air separation. In one embodiment, indirect coupling can also be referred to as capacitive coupling. For example, signal transmission is achieved by forming an equivalent capacitance through the coupling between the gaps of two conductive parts.

[0181] Element / device: Includes at least one of lumped elements / devices and distributed elements / devices.

[0182] Lumped element / device: Refers to the general term for all elements when the size of the element is much smaller than the wavelength corresponding to the operating frequency of the circuit. For a signal, regardless of the time, the characteristics of the element always remain fixed and are independent of frequency. Lumped elements / devices can include lumped capacitors, lumped inductors, etc.

[0183] Distributed element / device: Different from lumped elements, when a signal passes through an element, the characteristics of each point of the element itself will vary with the change of the signal. At this time, the element as a whole cannot be regarded as a single entity with fixed characteristics, but should be called a distributed element. Distributed elements / devices can include distributed capacitors, distributed inductors, etc.

[0184] Capacitance: It can be understood as lumped capacitance and / or distributed capacitance. Lumped capacitance includes capacitive components, such as capacitor elements; distributed capacitance (or distributed capacitance) includes the equivalent capacitance formed by a certain gap between two conductive parts.

[0185] Inductance: It can be understood as lumped inductance and / or distributed inductance. Lumped inductance includes inductive components, such as inductor elements; distributed inductance (or distributed inductance) includes the equivalent inductance formed by a certain length of conductive parts, such as the equivalent inductance formed by the curling or rotation of a conductor.

[0186] Radiator: It is a device in an antenna used to receive / transmit electromagnetic wave radiation. In some cases, "antenna" is narrowly understood as the radiator, which converts the guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy to radiate and receive radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted through the feeder line to the transmitting radiator, and through the radiator, it is converted into electromagnetic wave energy of a certain polarization and radiated in the required direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space back into modulated high-frequency current energy, and transmits it through the feeder line to the input end of the receiver.

[0187] The radiator can include conductors with specific shapes and sizes, such as linear or sheet-like, etc. The present application does not limit the specific shape. In one embodiment, the linear radiator can be simply referred to as a wire antenna. In one embodiment, the linear radiator can be realized by a conductive frame and can also be referred to as a frame antenna. In one embodiment, the linear radiator can be realized by a support conductor and can also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the linear radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of wire antennas include dipole antennas, half-wave dipole antennas, monopole antennas, loop antennas, inverted-F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna usually includes two radiating branches, and each branch is fed by the feeding part from the feeding end of the radiating branch. For example, an inverted-F antenna (Inverted-F Antenna, IFA) can be regarded as obtained by adding a grounding path to a monopole antenna. The IFA antenna has a feeding point and a grounding point, and is called an inverted-F antenna because its side view is in the shape of an inverted F. In one embodiment, the sheet radiator can include a microstrip antenna, or a patch antenna, such as a planar inverted-F antenna (also known as PIFA, Planar Inverted F Antenna). In one embodiment, the sheet radiator can be realized by a planar conductor (such as a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator can include a conductive sheet, such as a copper sheet, etc. In one embodiment, the sheet radiator can include a conductive coating, such as silver paste, etc. The shapes of the sheet radiator include circular, rectangular, annular, etc. The present application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a ground plane, where the dielectric substrate is disposed between the radiator and the ground plane.

[0188] The radiator may also include grooves or slits formed on a conductor. For example, closed or semi-closed grooves or slits are formed on a grounded conductor surface. In one embodiment, the slotted or slit radiator may be simply referred to as a slot antenna or a slit antenna. In one embodiment, the radial dimension (e.g., including the width) of the groove or slit of the slot antenna / slit antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length dimension can be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is around 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, the radiator with a closed groove or slit may be simply referred to as a closed slot antenna. In one embodiment, the radiator with a semi-closed groove or slit (e.g., adding an opening to a closed groove or slit) may be simply referred to as an open slot antenna. In some embodiments, the shape of the slit is elongated. In some embodiments, the length of the slit is about half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the slit is about an integer multiple of the wavelength (e.g., one dielectric wavelength). In some embodiments, the slit can be fed by a transmission line bridging one or both sides of it. Thus, a radio frequency electromagnetic field is excited on the slit, and electromagnetic waves are radiated into space. In one embodiment, the radiator of the slot antenna or slit antenna can be realized by a conductive frame grounded at both ends, and can also be referred to as a frame antenna; in this embodiment, it can be considered that the slot antenna or slit antenna includes a linear radiator, which is spaced from the floor and grounded at both ends of the radiator, thus forming a closed or semi-closed groove or slit. In one embodiment, the radiator of the slot antenna or slit antenna can be realized by a support conductor grounded at both ends, and can also be referred to as a support antenna.

[0189] The feeding circuit is a circuit for receiving and / or transmitting radio frequency signals. The feeding circuit may include a transceiver and a radio frequency front-end circuit (RF front end). In some cases, "feeding circuit" is narrowly understood as a radio frequency integrated circuit (RFIC). The RFIC can be considered to include a radio frequency front-end circuit (or a radio frequency front-end chip) and a transceiver. The feeding circuit has the function of converting radio waves (e.g., radio frequency signals) and signals (e.g., digital signals). Generally, it is considered as a part of radio frequency.

[0190] In some embodiments, the electronic device may further include a test socket (or referred to as a radio frequency socket or a radio frequency test socket). This test socket can be used to insert a coaxial cable to test the characteristics of the radio frequency front-end circuit or the radiator of the antenna through the cable. The radio frequency front-end circuit can be considered as the circuit part coupled between the test socket and the transceiver.

[0191] In some embodiments, the radio frequency front-end circuit can be integrated into a radio frequency front-end chip in an electronic device, or the radio frequency front-end circuit and the transceiver can be integrated into a radio frequency chip in the electronic device.

[0192] It should be understood that any two of the first / second / ... / Nth feeding circuits in this application can include the same transceiver. For example, one transmission channel in a transceiver serves as the first feeding circuit, and one receiving channel serves as the second feeding circuit. Or, for example, the first receiving channel in a transceiver serves as the first feeding circuit, and the second receiving channel serves as the second feeding circuit. Any two of the first / second / ... / Nth feeding circuits in this application can also include the same radio frequency front-end circuit. For example, signals are processed through a tuning circuit or an amplifier in a radio frequency front-end circuit.

[0193] It should also be understood that two of the first / second / ... / Nth feeding circuits in this application generally correspond to two radio frequency test sockets in an electronic device.

[0194] The matching circuit is a circuit for adjusting the radiation characteristics of the antenna. In one embodiment, the matching circuit is coupled between the feeding circuit and the corresponding radiator. In one embodiment, the matching circuit is coupled between the test socket and the radiator. Generally, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit can include a tuning circuit and / or components. The tuning circuit can be a component for switching the coupled connection of the radiator. The matching circuit has the functions of impedance matching and / or frequency tuning. Generally, it is considered to be a part of the antenna.

[0195] The grounding structure / feeding structure can include connectors, such as metal shrapnel. The radiator is coupled to the ground plane through the grounding structure / the feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure can include a transmission line / feeding wire, and the grounding structure can include a grounding wire.

[0196] End / point: The "end / point" in the first end / second end / feeding end / grounding end / feeding point / grounding point / connection point of the antenna radiator should not be narrowly understood as an endpoint or end that is physically disconnected from other radiators. It can also be considered as a certain point or a certain section on the continuous radiator. In one embodiment, the "end / point" can include the connection / coupling area on the antenna radiator that is coupled to other conductive structures. For example, the feeding end / feeding point can be the connection / coupling area on the antenna radiator that is coupled to the feeding structure or the feeding circuit (for example, the area facing a part of the feeding circuit). Another example is that the grounding end / grounding point can be the connection / coupling area on the antenna radiator that is coupled to the grounding structure or the grounding circuit (for example, the area facing a part of the grounding circuit).

[0197] Open end, closed end: In some embodiments, the open end and the closed end are, for example, relative to whether they are grounded. The closed end is grounded and the open end is not grounded. In some embodiments, the open end and the closed end are, for example, relative to other conductive bodies. The closed end is electrically connected to other conductive bodies and the open end is not electrically connected to other conductive bodies. In one embodiment, the open end can also be referred to as a floating end, a free end, an open end, or an open-circuit end. In one embodiment, the closed end can also be referred to as a grounded end or a short-circuit end. It should be understood that in some embodiments, other conductive bodies can be coupled and connected through the open end to transfer coupled energy (which can be understood as transferring current).

[0198] In some embodiments, the understanding of the "closed end" can also be from the perspective of current distribution. The closed end or the grounded end, etc., can be understood as the current maximum point on the radiator or the electric field minimum point on the radiator; in one embodiment, coupling electronic devices (such as capacitors, inductors, etc.) through the closed end can not change the current distribution characteristics of its current maximum point / electric field minimum point; in one embodiment, opening a slit at or near the closed end (such as a slit filled with insulating material) can not change the current distribution characteristics of its current maximum point / electric field minimum point.

[0199] In some embodiments, the understanding of the "open end" can also be from the perspective of current distribution. The open end or the floating end, etc., can be understood as the current minimum point on the radiator or the electric field maximum point on the radiator; in one embodiment, coupling electronic devices (such as capacitors, inductors, etc.) through the open end can not change the current distribution characteristics of its current minimum point / electric field maximum point.

[0200] It should be understood that coupling an electronic device (such as a capacitor, an inductor, etc.) to the radiator end at a slit (viewed from the structure of the radiator, similar to the opening of an open end or a floating end) can make the radiator end the current maximum point / electric field minimum point. In this case, it should be understood that the radiator end at this slit is actually the closed end or the grounded end, etc.

[0201] The "floating radiator" mentioned in the embodiments of the present application refers to a radiator that is not directly connected to the feeder / feeding stub and / or the ground wire / grounding stub, but is fed and / or grounded through an indirect coupling method.

[0202] It should be understood that the "floating" in the "floating end" and the "floating radiator" does not mean that there is no any structure around the radiator to support it. In one embodiment, the floating radiator can be, for example, a radiator disposed on the inner surface of an insulating rear cover.

[0203] In the embodiments of the present application, the same / different directions of the current should be understood as the directions of the main currents on the conductors on the same side being the same / different. For example, when exciting a current with a same-direction distribution (e.g., the current path is also bent or circular) on a bent or circular conductor, it should be understood that, for example, although the main currents excited on the conductors on both sides of a circular conductor (e.g., the conductors around a gap, on the conductors on both sides of the gap) are opposite in direction, they still belong to the definition of the current with a same-direction distribution in the embodiments of the present application. In one embodiment, the same direction of the current on a conductor may mean that there is no reverse point in the current on the conductor. In one embodiment, the reverse direction of the current on a conductor may mean that there is at least one reverse point in the current on the conductor. In one embodiment, the same direction of the currents on two conductors may mean that there is no reverse point in the currents on both conductors and they flow in the same direction. In one embodiment, the reverse direction of the currents on two conductors may mean that there is no reverse point in the currents on both conductors and they flow in opposite directions. The same / different directions of the currents on multiple conductors can be understood accordingly.

[0204] Resonant frequency: The resonant frequency is also called the resonance frequency. The resonant frequency can have a frequency range, that is, the frequency range where resonance occurs. The resonant frequency can be the frequency range where the return loss characteristic is less than -5 dB. The point with the strongest resonance can be called the resonant point, and the frequency corresponding to the resonant point is the center frequency point. The return loss characteristic of the center frequency can be less than -10 dB, -15 dB, or less than -20 dB. It should be understood that if there is no additional explanation, when the present application mentions that the antenna / radiator generates "the first / second... resonance", among them, the first resonance should be the fundamental mode resonance generated by the antenna / radiator, or rather, the resonance with the lowest frequency generated by the antenna / radiator. It should be understood that the antenna / radiator can generate one or more antenna modes according to the specific design, and each antenna mode can correspondingly generate a fundamental mode resonance.

[0205] Resonant frequency band: The range of the resonant frequency is the resonant frequency band, and the frequency range where the return loss characteristic of the internal frequency points within the resonance is less than -5 dB can be regarded as the resonant frequency band.

[0206] Communication frequency band / operating frequency band: No matter what type of antenna, it always operates within a certain frequency range (bandwidth). For example, for an antenna supporting Band 40, its operating frequency band includes the frequencies within the range of 2300 MHz to 2400 MHz, or rather, the operating frequency band of this antenna includes Band 40. The frequency range that meets the index requirements can be regarded as the operating frequency band of the antenna.

[0207] The resonant frequency band and the operating frequency band can be the same or can partially overlap. In one embodiment, one or more resonant frequency bands of the antenna can cover one or more operating frequency bands of the antenna.

[0208] Electrical length: It can refer to the ratio of the physical length (i.e., mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. The electrical length can satisfy the following formula:

[0209]

[0210] where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0211] Wavelength: Or the operating wavelength, which can be the wavelength corresponding to the center frequency of the resonant frequency or the center frequency of the operating frequency band supported by the antenna. For example, assuming the center frequency of the B1 uplink frequency band (resonant frequency from 1920 MHz to 1980 MHz) is 1955 MHz, the operating wavelength can be the wavelength calculated using the frequency of 1955 MHz. Not limited to the center frequency, the "operating wavelength" can also refer to the wavelength corresponding to a non - center frequency of the resonant frequency or the operating frequency band.

[0212] It should be understood that the wavelength of the radiation signal in air can be calculated as follows: (air wavelength, or vacuum wavelength) = speed of light / frequency, where the frequency is the frequency of the radiation signal (MHz), and the speed of light can be taken as 3×10 8 m / s. The wavelength of the radiation signal in a medium can be calculated as follows: where ε is the relative permittivity of the medium. The wavelength in the embodiments of the present application usually refers to the medium wavelength, which can be the medium wavelength corresponding to the center frequency of the resonant frequency or the medium wavelength corresponding to the center frequency of the operating frequency band supported by the antenna. For example, assuming the center frequency of the B1 uplink frequency band (resonant frequency from 1920 MHz to 1980 MHz) is 1955 MHz, the wavelength can be the medium wavelength calculated using the frequency of 1955 MHz. Not limited to the center frequency, the "medium wavelength" can also refer to the medium wavelength corresponding to a non - center frequency of the resonant frequency or the operating frequency band. For ease of understanding, the medium wavelength mentioned in the embodiments of the present application can be simply calculated through the relative permittivity of the medium filled on one side or multiple sides of the radiator.

[0213] Antenna system efficiency (total efficiency): It refers to the ratio of the input power to the output power at the port of the antenna.

[0214] Antenna radiation efficiency: It refers to the ratio of the power radiated by the antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. Among them, the active power input to the antenna = the input power of the antenna - the loss power; the loss power mainly includes the return loss power, the ohmic loss power of the metal, and / or the dielectric loss power. The radiation efficiency is a value that measures the radiation ability of the antenna, and both metal loss and dielectric loss are influencing factors of the radiation efficiency.

[0215] Those skilled in the art can understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship with dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna is characterized.

[0216] Antenna return loss: It can be understood as the ratio of the signal power reflected back to the antenna port through the antenna circuit to the transmission power of the antenna port. The smaller the reflected signal, the larger the signal radiated into space through the antenna, and the greater the radiation efficiency of the antenna. The larger the reflected signal, the smaller the signal radiated into space through the antenna, and the smaller the radiation efficiency of the antenna.

[0217] Antenna return loss can be represented by the S11 parameter, and S11 belongs to one of the S parameters. S11 represents the reflection coefficient, and this parameter can characterize the quality of the antenna transmission efficiency. The S11 parameter is usually negative. The smaller the S11 parameter, the smaller the antenna return loss, the smaller the energy reflected back by the antenna itself, that is, it means that the more energy actually enters the antenna, and the higher the system efficiency of the antenna; the larger the S11 parameter, the larger the antenna return loss, and the lower the system efficiency of the antenna.

[0218] It should be noted that in engineering, generally, the S11 value of -6 dB is used as a standard. When the S11 value of the antenna is less than -6 dB, it can be considered that the antenna can work normally, or it can be considered that the transmission efficiency of the antenna is good.

[0219] Antenna pattern: Also known as the radiation pattern. It refers to the graph of the relative field strength (normalized modulus value) of the antenna radiation field changing with direction at a certain distance (far field) from the antenna. Usually, it is represented by two mutually perpendicular plane patterns passing through the maximum radiation direction of the antenna.

[0220] The antenna pattern usually has multiple radiation beams. Among them, the radiation beam with the largest radiation intensity is called the main lobe, and the remaining radiation beams are called side lobes or minor lobes. Among the side lobes, the side lobe in the direction opposite to the main lobe is also called the back lobe.

[0221] Beam width: It refers to the range of the angle formed with the direction pointing to the top of the electronic device (for example, the y direction) within the first angle, and the gain of the pattern generated by the antenna is greater than or equal to the threshold. The first angle is the beam width. When the first angle is large, for example, greater than or equal to 60°, it can be considered that the antenna has the characteristics of a wide beam, and the antenna has good radiation characteristics within this angle range.

[0222] Directivity: Also known as the directivity of the antenna. It refers to the ratio of the maximum power density to the average value on the antenna radiation pattern at a certain distance from the antenna (far field), which is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of the antenna. The larger the directivity, the more the energy radiated by the antenna in a certain direction accounts for, and the more concentrated the energy radiation is.

[0223] Antenna gain: It is used to characterize the degree to which the antenna concentrates and radiates the input power. Generally, the narrower the main lobe and the smaller the side lobes of the antenna radiation pattern, the higher the antenna gain.

[0224] Polarization direction of the antenna: At a given point in space, the electric field strength E (vector) is a function of time t. As time goes by, the end point of the vector periodically depicts a trajectory in space. If the trajectory is a straight line and perpendicular to the ground, it is called vertical polarization; if it is horizontal to the ground, it is called horizontal polarization. If the trajectory is an ellipse or a circle, and when observed along the propagation direction, it rotates clockwise or counterclockwise with time, it is called right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP), respectively.

[0225] Ground (Floor) (ground, GND): It can generally refer to at least a part of any ground layer, ground plane, or ground metal layer, etc. inside an electronic device (such as a mobile phone), or at least a part of any combination of the above-mentioned ground layer, ground plane, or ground component, etc. "Ground / Floor" can be used for grounding components inside an electronic device, or in other words, can be used as the reference ground for components inside an electronic device. Usually, a large area of metal (for example, a metal layer) inside an electronic device can be used as "Ground / Floor". In one embodiment, "Ground / Floor" can include any one or more of the following: the ground layer of the circuit board of the electronic device, the ground plane formed by the middle frame of the electronic device, the ground metal layer formed by the metal film under the screen, the conductive ground layer of the battery, the metal rotating shaft of the foldable electronic device, the metal back cover of the electronic device (for example, when at least a part of the back cover is metal), and the conductive or metal components electrically connected to the above-mentioned ground layer / ground plane / metal layer. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12 - 14-layer board with 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric layers or insulating layers such as fiberglass, polymers, etc. In one embodiment, the circuit board includes a dielectric substrate, a ground layer, and a trace layer, and the trace layer and the ground layer are electrically connected through vias. In one embodiment, components such as a display, a touch screen, an input button, a transmitter, a processor, a memory, a battery, a charging circuit, a system on chip (SoC), etc. can be mounted on the circuit board or connected to the circuit board; or electrically connected to the trace layer and / or the ground layer in the circuit board. For example, a radio frequency source is disposed on the trace layer.

[0226] Any of the above-mentioned ground layer, ground plane, or ground metal layer is made of a conductive material. In one embodiment, the conductive material can be any one of the following materials: copper, aluminum, stainless steel, brass, and their alloys, copper foil on an insulating substrate, aluminum foil on an insulating substrate, gold foil on an insulating substrate, silver-plated copper, silver-plated copper foil on an insulating substrate, silver foil on an insulating substrate, and tin-plated copper, cloth impregnated with graphite powder, a substrate coated with graphite, a copper-plated substrate, a brass-plated substrate, and an aluminum-plated substrate. Those skilled in the art can understand that the ground layer / ground plane / ground metal layer can also be made of other conductive materials.

[0227] Grounding: It means achieving coupling with the above-mentioned Ground / Floor through a grounding structure and / or a grounding circuit. In one embodiment, grounding can be through physical grounding, for example, through some structural components of the middle frame to achieve physical grounding at specific positions on the frame (or called, physical ground). In one embodiment, grounding can be through device grounding, for example, through devices such as capacitors / inductors / resistors in series or parallel for grounding (or called, device ground).

[0228] The technical solutions of the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0229] As Figure 1 shown, the electronic device 100 may include: a cover 13, a display / display module 15, a printed circuit board (PCB) 17, a middle frame 19, and a rear cover 21. It should be understood that in some embodiments, the cover 13 may be a cover glass, or may be replaced with a cover made of other materials, such as a cover made of PET (Polyethylene terephthalate) material, etc.

[0230] Among them, the cover 13 may be disposed closely to the display module 15, and may mainly be used to protect the display module 15 and prevent dust.

[0231] In one embodiment, the display module 15 may include a liquid crystal display (LCD) panel, a light emitting diode (LED) display panel, an organic light-emitting diode (OLED) display panel, etc., and the embodiments of the present application are not limited thereto.

[0232] The middle frame 19 mainly plays a supporting role for the whole machine. Figure 1As shown in the figure, the PCB 17 is disposed between the middle frame 19 and the rear cover 21. It should be understood that in one embodiment, the PCB 17 may also be disposed between the middle frame 19 and the display module 15, and the embodiments of the present application do not limit this. Among them, the printed circuit board PCB 17 may adopt a flame-retardant material (FR-4) dielectric board, or a Rogers dielectric board, or a mixed dielectric board of Rogers and FR-4, and so on. Here, FR-4 is a code for a flame-retardant material grade, and the Rogers dielectric board is a high-frequency board. Components are carried on the PCB 17, for example, radio frequency chips and the like. In one embodiment, a metal layer may be provided on the printed circuit board PCB 17. This metal layer can be used for grounding the components carried on the printed circuit board PCB 17, and can also be used for grounding other components, such as a bracket antenna, a frame antenna, etc. This metal layer can be called a floor, or a ground plane, or a ground layer. In one embodiment, this metal layer can be formed by etching metal on the surface of any layer of the dielectric board in the PCB 17. In one embodiment, the metal layer for grounding can be disposed on the side of the printed circuit board PCB 17 close to the middle frame 19. In one embodiment, the edge of the printed circuit board PCB 17 can be regarded as the edge of its ground layer. In one embodiment, the metal middle frame 19 can also be used for grounding the above components. The electronic device 100 may also have other floors / ground planes / ground layers. As described above, details are not elaborated here.

[0233] Due to the compactness inside the electronic device, generally, floors / ground planes / ground layers are provided in the internal space within 0-2 mm from the inner surface of the frame (for example, the printed circuit board, the middle frame, the screen metal layer, the battery, etc. can all be regarded as part of the floor). In one embodiment, a dielectric is filled between the frame and the floor. The length and width of the rectangle formed by surrounding the inner surface contour of the filled dielectric can be simply regarded as the length and width of the floor; or the length and width of the rectangle formed by surrounding the contour formed by superimposing all the conductive parts inside the frame can be regarded as the length and width of the floor.

[0234] Among them, the electronic device 100 may also include a battery (not shown in the figure). The battery may be disposed between the middle frame 19 and the rear cover 21, or may be disposed between the middle frame 19 and the display module 15, and the embodiments of the present application do not limit this. In some embodiments, the PCB 17 is divided into a main board and a daughter board, and the battery can be disposed between the main board and the daughter board. Among them, the main board can be disposed between the middle frame 19 and the upper edge of the battery, and the daughter board can be disposed between the middle frame 19 and the lower edge of the battery.

[0235] The electronic device 100 may further include a frame 11, and the frame 11 may include a conductive material such as metal. The frame 11 may be disposed between the display module 15 and the rear cover 21 and extend circumferentially around the periphery of the electronic device 100. The frame 11 may have four sides surrounding the display module 15 to help fix the display module 15.

[0236] In one implementation, the frame 11 mainly including a conductive material may be referred to as the conductive frame or metal frame of the electronic device 100, which is suitable for the industrial design (ID) of a metal appearance. In one implementation, the outer surface of the frame 11 is mainly a conductive material, such as a metal material, so as to form the appearance of a metal frame. In these implementations, the conductive part including the outer surface in the frame 11 can be used as the antenna radiator of the electronic device 100 and is usually referred to as the frame antenna.

[0237] In another implementation, the outer surface of the frame 11 is mainly a non-conductive material, such as plastic, to form the appearance of a non-metal frame, which is suitable for non-metal ID. In one implementation, the inner surface of the frame 11 may include a conductive material, such as a metal material. In this implementation, the conductive part on the inner surface of the frame 11 can be used as the antenna radiator of the electronic device 100. It should be understood that the radiator disposed on the inner surface of the frame 11 (or rather, the conductive material on the inner surface) can be arranged close to the non-conductive material of the frame 11 to minimize the volume occupied by the radiator and be closer to the outside of the electronic device 100 to achieve a better signal transmission effect, and it can also be referred to as the frame antenna. It should be noted that the antenna radiator being arranged close to the non-conductive material of the frame 11 means that the antenna radiator can be arranged closely against the inner surface of the non-conductive material, can be embedded inside the non-conductive material, or can be arranged close to the inner surface of the non-conductive material. For example, there can be a certain small gap between the antenna radiator and the inner surface of the non-conductive material. It should be understood that both the conductive material and the non-conductive material can be regarded as part of the frame 11.

[0238] It should be understood that there may be insulating gaps on the frame 11. The conductor portions of the frame between the insulating gaps, between the insulating gaps and / or between the insulating gaps and the ground point serve as radiators, thereby forming a frame antenna (it should be understood that the radiator of the frame antenna may also include the conductor portion of the frame between the ground points and the ground points). Among them, when the frame 11 is formed of a conductive material such as metal, the insulating gap can be understood as a gap in the frame 11 filled with a non-metallic material (insulating material). In this case, the gap is visible on the appearance surface. When the outer surface of the frame 11 is a non-conductive material, the insulating gap can be understood as the end of the radiator on the inner surface of the frame 11 (for example, the end not electrically connected to other radiators or conductors), or as the gap formed between the radiators on the inner surface of the frame 11. A non-metallic material (insulating material) can be provided in this gap, or a non-metallic material may not be provided, for example, filled with air. In this case, the gap is not visible on the appearance surface.

[0239] In Figure 1 In the following embodiments, the frame 11 of the electronic device 100 is taken as a metal frame (conductive frame), and the slits visible on the appearance surface (insulating gaps visible on the appearance surface) are taken as examples for illustration. In this case, the metal frame serves as at least a part of the antenna radiator. It should be understood that when the frame 11 of the electronic device 100 is a non-metal frame (slits not visible on the appearance surface), the same technical effects can also be achieved. For the sake of brevity of the discussion, they will not be elaborated one by one.

[0240] The middle frame 19 may include the frame 11. The middle frame 19 including the frame 11 as an integral part can support the electronic devices in the whole machine. The cover plate 13 and the rear cover 21 are respectively covered along the upper and lower edges of the frame to form the outer shell or housing of the electronic device. In one embodiment, the cover plate 13, the rear cover 21, the frame 11 and / or the middle frame 19 can be collectively referred to as the outer shell or housing of the electronic device 100. It should be understood that the "outer shell or housing" can be used to refer to a part or all of any one of the cover plate 13, the rear cover 21, the frame 11 or the middle frame 19, or to a part or all of any combination of the cover plate 13, the rear cover 21, the frame 11 or the middle frame 19.

[0241] The frame 11 can at least partially serve as an antenna radiator to receive / transmit radio frequency signals. There may be a gap between this part of the frame serving as the radiator and the other parts of the middle frame 19, so as to ensure that the antenna radiator has a good radiation environment. In one embodiment, the middle frame 19 can be provided with apertures at this part of the frame serving as the radiator to facilitate the radiation of the antenna.

[0242] Alternatively, the frame 11 may not be regarded as part of the middle frame 19. In one embodiment, the frame 11 may be connected to and integrally formed with the middle frame 19. In another embodiment, the frame 11 may include protruding members extending inwardly to be connected to the middle frame 19, for example, by means of elastic sheets, screws, welding, etc. The protruding members of the frame 11 may also be used to receive feed signals, such that at least a part of the frame 11 serves as a radiator of the antenna to receive / transmit frequency signals. There may be a gap between this part of the frame serving as the radiator and the middle frame 19, so as to ensure that the antenna radiator has a good radiation environment and the antenna has a good signal transmission function.

[0243] Among them, the rear cover 21 may be a rear cover made of a metal material; it may also be a rear cover made of a non-conductive material, such as a glass rear cover, a plastic rear cover and other non-metal rear covers; it may also be a rear cover made of both conductive and non-conductive materials. In one embodiment, the rear cover 21 including a conductive material may replace the middle frame 19 and, together with the frame 11, serve as an integral part to support the electronic devices in the whole machine.

[0244] In one embodiment, the middle frame 19 and / or the conductive part of the rear cover 21 may serve as the reference ground of the electronic device 100, wherein the frame 11, the PCB 17, etc. of the electronic device may be grounded through electrical connection with the middle frame.

[0245] The antenna of the electronic device 100 may also be disposed inside the housing, such as a bracket antenna, a millimeter-wave antenna, etc. ( Figure 1 not shown in the figure). The clearance of the antenna disposed inside the housing may be obtained by a slit / aperture on any one of the middle frame, and / or the frame, and / or the rear cover, and / or the display screen, or by a non-conductive gap / aperture formed between any several of them. The setting of the antenna clearance can ensure the radiation characteristics of the antenna. It should be understood that the antenna clearance may be a non-conductive area formed by any conductive component in the electronic device 100, and the antenna radiates signals to the external space through this non-conductive area. In one embodiment, the form of the antenna 40 may be an antenna form based on a flexible printed circuit (FPC), an antenna form based on laser-direct-structuring (LDS), or a microstrip disk antenna (MDA), etc. In one embodiment, the antenna may also adopt a transparent structure embedded inside the screen of the electronic device 100, such that the antenna is a transparent antenna unit embedded inside the screen of the electronic device 100.

[0246] Figure 2FIG. 0 is a schematic structural diagram of a foldable electronic device 100 provided by an embodiment of the present application. The foldable electronic device 100 may be an electronic device with a folding function such as a mobile phone, a tablet computer, an e-reader, a laptop computer, a wearable device such as a watch, etc. Figure 2 The illustrated embodiment is described by taking a foldable mobile phone as an example.

[0249] Figure 2 the middle frame 19 in

[0250] the middle frame 19 in

[0251] ), a second cover 124, and a rotating shaft 125. In some embodiments, the first frame 121, the first cover 122, the second frame 123, and the second cover 124 may form a first housing 126 (which may correspond to Figure 1 the middle frame 19 in Figure 1 ), and a second housing 127 (which may correspond to

[0249] Figure 2 the middle frame 19 in

[0250] the middle frame 19 in

[0251] ), a second cover 124, and a rotating shaft 125. In some embodiments, the first frame 121, the first cover 122, the second frame 123, and the second cover 124 may form a first housing 126 (which may correspond to Figure 1 the middle frame 19 in Figure 1 ), and a second housing 127 (which may correspond to

[0249] Figure 2 the middle frame 19 in

[0250] the middle frame 19 in

[0251] ), a second cover 124, and a rotating shaft 125. In some embodiments, the first frame 121, the first cover 122, the second frame 123, and the second cover 124 may form a first housing 126 (which may correspond to Figure 1 the middle frame 19 in Figure 1 ), and a second housing 127 (which may correspond to

[0249] Figure 2 the middle frame 19 in

[0250] the middle frame 19 in

[0251] ), a second cover 124, and a rotating shaft 125. In some embodiments, the first frame 121, the first cover 122, the second frame 123, and the second cover 124 may form a first housing 126 (which may correspond to Figure 1The first frame 121 can surround the outer periphery of the first cover 122, and at least part of the first frame 121 can also surround the outer periphery of the first display portion 111. The first display portion 111 can be arranged parallel and spaced apart from the first cover 122, and the first display portion 111 and the first cover 122 can be located on both sides of the first frame 121. The spaced space between the first display portion 111 and the first cover 122 can be used to arrange components of the foldable electronic device 100, such as antennas, circuit board assemblies, etc.

[0252] The second frame 123 can surround the outer periphery of the second cover 124, and at least part of the second frame 123 can also surround the outer periphery of the second display portion 112. The second display portion 112 can be arranged parallel and spaced apart from the second cover 124, and the second display portion 112 and the second cover 124 can be located on both sides of the second frame 123. The spaced space between the second display portion 112 and the second cover 124 can be used to arrange components of the foldable electronic device 100, such as antennas, circuit board assemblies, etc.

[0253] In an embodiment provided by the present application, the cover and the frame can be two parts of the housing of the foldable electronic device 100. The cover and the frame can be connected, and the form of this connection does not belong to assembly methods such as snap connection, adhesion, welding, riveting, clearance fit, etc. The connection relationship between the cover and the frame is usually difficult to be separated. In another embodiment provided by the present application, the cover and the frame can be two different components. By assembling the cover and the frame together, the housing of the foldable electronic device 100 can be formed.

[0254] The rotating shaft 125 can be connected between the first housing 126 and the second housing 127. Under the action of the rotating shaft 125, the first housing 126 and the second housing 127 can approach or move away from each other. Correspondingly, the first display portion 111 of the flexible display screen 110 and the second display portion 112 of the flexible display screen 110 can approach or move away from each other, so that the flexible display screen 110 can be folded or unfolded.

[0255] In an example, the rotating shaft 125 can include, for example, a main shaft, a first connection component, and a second connection component. The first connection component can be fixed to the first cover 122, the second connection component can be fixed to the second cover 124, and the first connection component and the second connection component can rotate relative to the main shaft. Through the relative movement of the first connection component and the second connection component, the relative movement of the first housing 126 and the second housing 127 can be driven to realize the opening and closing function of the foldable electronic device 100.

[0256] Figure 2The foldable electronic device 100 shown is currently in a possible unfolded state. In this unfolded state, the angle between the first housing 126 and the second housing 127 can be 180°, or it can be referred to as a flattened state. The flexible display screen 110 can be in the flattened state as shown in Figure 2 shown.

[0257] Among them, the flexible display screen 110 being in the flattened state can be understood as the angle formed between the first display part 111 corresponding to the first housing 126 and the second display part 112 corresponding to the second housing 127 being 180°. Due to certain errors that may exist in engineering implementation, when the angle formed between the first display part 111 and the second display part 112 is between 170° and 190°, it can be considered that the flexible display screen 110 is in the flattened state.

[0258] Figure 3 A possible folded state of the foldable electronic device 100 is shown. Among them, Figure 3 shows the outward folding state of the foldable electronic device 100 (the outward folding state can be simply referred to as the outer fold state). Figure 3 The shown outward folding state can be, for example, a left - right outward folding state or an up - down outward folding state. The following combines Figure 2 and Figure 3 to elaborate on a possible folded state of the foldable electronic device 100.

[0259] In the embodiments of the present application, the foldable electronic device 100 being in the folded state can mean that the foldable electronic device 100 is currently bent and the degree of bending of the foldable electronic device 100 reaches the maximum. At this time, the first cover 122 and the second cover 124 can be approximately parallel, spaced apart from each other, and arranged face to face, and the distance between the first cover 122 and the second cover 124 is the smallest. At least part of the first housing 126 and the second housing 127 is received in the space enclosed by the flexible display screen 110; the first display part 111, the first housing 126, the second housing 127, and the second display part 112 are arranged in a stacked manner in sequence. Similarly, the first display part 111 and the second display part 112 can be approximately parallel and spaced apart from each other, and the distance between the first cover 122 and the second cover 124 is less than the distance between the first display part 111 and the second display part 112. At this time, the first display part 111 and the second display part 112 can be regarded as being located on different planes.

[0260] Combined with Figure 2 and Figure 3, when the foldable electronic device 100 is in the outward folding state, the first cover 122 and the second cover 124 can approach each other, and the first display part 111 and the second display part 112 can approach each other. The first display part 111, the second display part 112 and the foldable display part 113 can form a housing area for accommodating the first cover 122, the second cover 124 and the rotating shaft 125. That is to say, the first cover 122, the second cover 124 and the rotating shaft 125 can be received in the spaced space between the first display part 111 and the second display part 112.

[0261] It should be understood that the foldable electronic device 100 can be folded inward (the inward folding state can be simply referred to as the inner folding state). When the foldable electronic device 100 is in the inner folding state, the first cover 122 and the second cover 124 can approach each other, and the first display part 111 and the second display part 112 can approach each other. The first cover 122, the second cover 124 and the rotating shaft 125 can form a housing area for accommodating the first display part 111, the second display part 112 and the foldable display part 113. That is to say, the first display part 111, the second display part 112 and the foldable display part 113 can be received in the spaced space between the first cover 122 and the second cover 124.

[0262] The foldable electronic device 100 can be switched between a folded state and an unfolded state. When the foldable electronic device 100 is in the folded state, the occupied space of the foldable electronic device 100 is relatively small; when the foldable electronic device 100 is in the unfolded state, the foldable electronic device 100 can display a relatively large screen to increase the user's viewing range. It should be understood that the folded state includes a closed state, at which time the occupied space of the foldable electronic device 100 is the smallest; the unfolded state includes a flattened state, at which time the occupied space of the foldable electronic device 100 is the largest.

[0263] The foldable electronic device 100 may further include a third housing 128 and a rotating shaft 129, as Figure 4 shown. The rotating shaft 129 can be connected between the third housing 128 and the second housing 127. The third housing 128 and the second housing 127 can approach each other or move away from each other. As the number of foldable parts of the foldable electronic device 100 increases, when the screen size remains the same in the unfolded state, the occupied space of the foldable electronic device 100 can be further reduced in the folded state.

[0264] And in Figure 4 the foldable electronic device 100 shown, since it has three foldable parts (the first housing 126, the second housing 127 and the third housing 128), therefore, the foldable electronic device 100 has at least three forms: 1. Unfolded state; 2. Folded state; 3. Partially unfolded state.

[0265] 1. As shown in Figure 4 , a possible unfolded state of the foldable electronic device 100 is shown. In the unfolded state, the angle between the first housing 126, the second housing 127, and the third housing 128 can be approximately 180°. The flexible display screen 110 can be in the unfolded state.

[0266] 2. As shown in Figure 5 , a possible folded state (tri-fold state) of the foldable electronic device 100 is shown. In the folded state, the first housing 126 rotates with respect to the second housing 127 along the rotation axis 125, and the second housing 127 rotates with respect to the third housing 128 along the rotation axis 129, so that the bending degree of the foldable electronic device 100 reaches the maximum. At this time, the first housing 126, the second housing 127, and the third housing 128 can be regarded as being in different planes.

[0267] It should be understood that, for the sake of simplicity of discussion, in the structure shown in Figure 5 , the folded state of the foldable electronic device 100 is an S-fold (the side of the foldable electronic device 100 is S-shaped, and the second housing 127 is located between the first housing 126 and the third housing 128). In one embodiment, the folded state of the foldable electronic device 100 can also be a G-fold (the side of the foldable electronic device 100 is G-shaped, and the third housing 128 is located between the first housing 126 and the second housing 127). The embodiments of the present application do not limit the folded state of the foldable electronic device 100.

[0268] 3. As shown in Figure 6 , a possible partially unfolded state (bi-fold state) of the foldable electronic device 100 is shown. In the partially unfolded state, the angle between the first housing 126 and the second housing 127 can be approximately 180°, and the second housing 127 rotates with respect to the third housing 128 along the rotation axis 129, so that the third housing 128 approaches the second housing 127. At this time, the first housing 126 and the second housing 127 are regarded as being in the same plane, and the second housing 127 and the third housing 128 can be regarded as being in different planes. In another possible partially unfolded state, the angle between the third housing 128 and the second housing 127 can be approximately 180°, and the first housing 126 rotates with respect to the second housing 127 along the rotation axis 125, so that the first housing 126 approaches the second housing 127.

[0269] Figure 1 And Figure 2 only schematically shows some components included in the electronic device 100 and the foldable electronic device 100. The actual shapes, actual sizes, and actual structures of these components are not limited by the above-mentioned drawings.

[0270] It should be understood that in the embodiments of the present application, the surface where the display screen of the electronic device is located can be regarded as the front surface, the surface where the rear cover is located as the back surface, and the surface where the frame is located as the side surface.

[0271] It should be understood that in the embodiments of the present application, when it is considered that the user holds (usually vertically and facing the screen) the electronic device, the orientation of the electronic device has a top, a bottom, a left side, and a right side. It should be understood that in the embodiments of the present application, when it is considered that the user holds (usually vertically and facing the screen) the electronic device, the orientation of the electronic device has a top, a bottom, a left side, and a right side.

[0272] First, Figure 7 and Figure 8 will be used to introduce two antenna modes involved in the present application. Among them, Figure 7 is a schematic diagram of the structure of a common mode of an antenna provided in the present application and the corresponding current and electric field distributions. Figure 8 is a schematic diagram of the structure of another differential mode of an antenna provided in the present application and the corresponding current and electric field distributions. Figure 7 and Figure 8 The two ends of the antenna radiator in are open, and its common mode and differential mode can be respectively called the line common mode and the line differential mode.

[0273] It should be understood that the "common mode" or "CM mode" in the present application includes the line common mode and the slot common mode, while the "differential mode" or "DM mode" in the present application includes the line differential mode and the slot differential mode, which can be specifically determined according to the structure of the antenna.

[0274] It should be understood that the "common-differential mode" or "CM-DM mode" in the present application refers to the line common mode and the line differential mode generated on the same radiator, or refers to the slot common mode and the slot differential mode generated on the same radiator, which can be specifically determined according to the structure of the antenna.

[0275] 1. Wire common mode (CM)

[0276] Figure 7 In (a) of, it shows that the two ends of the radiator of antenna 40 are open, and a feeding circuit (not shown in the figure) is connected at the middle position 41. In one embodiment, the feeding form of antenna 40 adopts symmetrical feed. The feeding circuit can be connected to the middle position 41 of antenna 40 through a feeding wire 42. It should be understood that symmetrical feed can be understood as one end of the feeding circuit is connected to the radiator, and the other end is coupled to the ground through the floor. Among them, the connection point (feeding point) of the feeding circuit and the radiator is located at the center of the radiator. The center of the radiator can be, for example, the midpoint of the geometric structure, or the midpoint of the electrical length (or a region within a certain range near the above midpoint).

[0277] The middle position 41 of the antenna 40 can be, for example, the geometric center of the antenna, or the midpoint of the electrical length of the radiator. For example, the connection point between the feeder line 42 and the antenna 40 covers the middle position 41.

[0278] Figure 7 (b) in shows the current and electric field distributions of the antenna 40. As Figure 7 shown in (b), the current shows a reverse distribution on both sides of the middle position 41, for example, a symmetric distribution; the electric field shows a same-direction distribution on both sides of the middle position 41. As Figure 7 shown in (b), the current at the feeder line 42 shows a same-direction distribution. Based on the same-direction distribution of the current at the feeder line 42, Figure 7 the feeding shown in (a) can be called line CM feeding. Based on the reverse distribution of the current on both sides of the connection point between the radiator and the feeder line 42, Figure 7 the antenna pattern shown in (b) can be called line CM mode (which can also be simply referred to as CM mode. For example, for a wire antenna, the CM mode refers to the line CM mode). Figure 7 The current and electric field shown in (b) can be respectively called the current and electric field of the line CM mode.

[0279] The current is stronger at the middle position 41 of the antenna 40 (the current maximum point is near the middle position 41 of the antenna 40) and weaker at both ends of the antenna 40, as Figure 7 shown in (b). The electric field is weaker at the middle position 41 of the antenna 40 and stronger at both ends of the antenna 40.

[0280] 2. Line differential mode (DM) mode

[0281] As Figure 8 shown in (a), the left and right ends of the two radiators of the antenna 50 are open ends, and a feeding circuit is connected at the middle position 51. In one embodiment, the feeding form of the antenna 50 adopts anti-symmetrical feeding. One end of the feeding circuit is connected to one of the radiators through the feeder line 52, and the other end of the feeding circuit is connected to the other radiator through the feeder line 52. The middle position 51 can be the geometric center of the antenna 50, or the gap formed between the radiators.

[0282] It should be understood that the "central anti-symmetrical feeding" mentioned in this application can be understood as that the positive and negative poles of the feeding unit are respectively connected to two connection points near the above-mentioned midpoints of the radiators. In one embodiment, the signal amplitudes output by the positive and negative poles of the feeding unit are the same, and the phases are opposite, for example, the phase difference is 180°±10°.

[0283] Figure 8 Figure (b) in [reference] shows the current and electric field distributions of the antenna 50. As Figure 8 shown in Figure (b) in [reference], the current shows a co-directional distribution on both sides of the middle position 51 of the antenna 50, for example, an anti-symmetric distribution; the electric field shows an anti-directional distribution on both sides of the middle position 51. As Figure 8 shown in Figure (b) in [reference], the current at the feeder line 52 shows an anti-directional distribution. Based on the anti-directional current distribution at the feeder line 52, Figure 8 the feeding shown in Figure (a) in [reference] can be called line DM feeding. Based on the co-directional current distribution on both sides of the connection between the radiator and the feeder line 52, Figure 8 the antenna pattern shown in Figure (b) in [reference] can be called line DM mode (which can also be simply called DM mode. For example, for a wire antenna, the DM mode refers to the line DM mode). Figure 8 The current and electric field shown in Figure (b) in [reference] can be respectively called the current and electric field of the line DM mode. It should be understood that based on the co-directional current distribution on both sides of the connection between the radiator and the feeder line 52, Figure 8 the antenna pattern shown in Figure (b) in [reference] can also be called half-wave antenna mode, or half-wavelength mode, or simply half mode.

[0284] In one embodiment, in the line DM mode, or half mode, the current is stronger at the middle position 51 of the antenna 50 (the current maximum is near the middle position 51 of the antenna 50), and weaker at both ends of the antenna 50, as Figure 8 shown in Figure (b) in [reference]. The electric field is weaker at the middle position 51 of the antenna 50 and stronger at both ends of the wire antenna 50.

[0285] It should be understood that for the antenna radiator, it can be understood as a metal structure that generates radiation, and the number can be one piece, as Figure 7 shown in [reference], or it can also be two pieces, as Figure 8 shown in [reference], and can be adjusted according to actual design or production needs. For example, for the line CM mode, two radiators can also be used as Figure 8 shown in [reference]. The two radiators are arranged with their ends opposite to each other and separated by a gap, and symmetric feeding is used at the mutually approaching ends. For example, the same feed signal is fed into the mutually approaching ends of the two radiators respectively, and similar effects to the antenna structure shown in Figure 7 can also be obtained. Correspondingly, for the line DM mode, one radiator can also be used as Figure 7 shown in [reference]. Two feeding points are set at the middle position of the radiator and anti-symmetric feeding is used. For example, signals with the same amplitude and opposite phases are fed into the two symmetric feeding points on the radiator respectively, and similar effects to the antenna structure shown in Figure 8 can also be obtained.

[0286] 3. Line CM - DM Mode

[0287] The above Figure 7 and Figure 8 respectively show that when both ends of the radiator are open, different feeding methods are used to generate the line CM mode and the line DM mode respectively.

[0288] When the feeding form of the antenna adopts asymmetric feeding (the feeding point deviates from the middle position of the radiator, including edge feeding or offset feeding), or the grounding point of the radiator (the coupling point with the floor) is asymmetric (the grounding point deviates from the middle position of the radiator), the antenna can simultaneously generate the first resonance and the second resonance, corresponding to the line CM mode and the line DM mode respectively. For example, the first resonance corresponds to the line CM mode, and the current and electric field distributions are as shown in Figure 7 (b) therein. The second resonance corresponds to the line DM mode, and the current and electric field distributions are as shown in Figure 8 (b) therein.

[0289] Figure 9 FIG. is a schematic diagram of a usage scenario of satellite communication provided by an embodiment of the present application.

[0290] As shown in Figure 9 , when a user conducts satellite communication through an electronic device, it is necessary to point the area with better radiation characteristics of the antenna in the electronic device towards the satellite to achieve satellite pointing (establish a communication connection with the satellite).

[0291] During satellite communication, when the relative position between the electronic device and the satellite changes (for example, a low - earth - orbit satellite moves), and the posture of the user holding the electronic device does not change, the maximum radiation direction of the antenna will deviate from the target radiation direction (for example, the top direction of the electronic device, and the top direction can be understood as the direction from the bottom to the top of the electronic device). In this case, the electronic device and the communication satellite cannot maintain a good satellite - pointing state, resulting in problems such as poor communication quality or even disconnection, which greatly affects the user's communication experience.

[0292] It should be understood that the target radiation direction of the antenna described in the embodiments of the present application can be understood as the direction of the communication satellite relative to the position of the electronic device 100, and can be understood as the top direction of the electronic device in the embodiments of the present application. When the maximum radiation direction of the antenna pattern generated is close to the target radiation direction, it is convenient to establish a good communication connection between the electronic device 100 and the communication satellite.

[0293] The present application provides an electronic device, which includes a first antenna and a second antenna. The operating frequency bands of the first antenna and the second antenna include a satellite communication frequency band. The first antenna and the second antenna can generate different maximum radiation directions, and the electronic device can perform satellite communication by switching between the first antenna and the second antenna, or, simultaneously perform satellite communication with the first antenna and the second antenna, which can improve the user experience during satellite communication.

[0294] It should be understood that the antennas and their radiators described in the embodiments of the present application can have different communication functions in different usage scenarios of the electronic device. For example, in the embodiments of the present application, taking the communication of the electronic device under the first satellite system as an example, in this usage scenario, the antennas and their radiators are used to support the communication function of the first satellite system. For example, they can be used to generate resonances and radiation patterns suitable for the communication of the first satellite system. In other scenarios, for example, when the electronic device is not performing satellite communication under the first satellite system, the antennas and their radiators can be used to support the communication functions of other systems. For example, they can be used as antenna radiators or parasitic stubs in a cellular system, or, they can be used as antenna radiators or parasitic stubs in wireless network communication technology (WiFi).

[0295] Figure 10 It is a schematic diagram of an electronic device 100 provided by an embodiment of the present application.

[0296] As Figure 10 shown, the electronic device 100 includes a first antenna 301 and a second antenna 302.

[0299] The operating frequency bands of the first antenna 301 and the second antenna 302 can both include at least some frequency bands in the satellite communication system.

In one embodiment, when the first antenna 301 and / or the second antenna 302 operate in the low-earth orbit satellite system (the operating frequency band of the first antenna 301 and / or the second antenna 302 includes at least some frequency bands in the low-earth orbit satellite system), the electronic device 100 can perform voice communication, send or receive short messages and pictures, and perform functions such as accessing the Internet through the first antenna 301 and / or the second antenna 302. The low-earth orbit satellite can also have some functions similar to those of a base station.

[0303] In one embodiment, the first feeding circuit 311 is used to transmit radio frequency signals in the satellite communication frequency band. In one embodiment, the second feeding circuit 321 is used to transmit radio frequency signals in the satellite communication frequency band.

[0304] In one embodiment, the satellite communication frequency band includes a first frequency band and a second frequency band.

In one embodiment, the first feeding circuit 311 is used to transmit radio frequency signals in the first frequency band or the second frequency band. In one embodiment, the second feeding circuit 321 is used to transmit radio frequency signals in the first frequency band or the second frequency band.

[0305] It should be understood that in the embodiments of the present application, the feeding circuit can be understood as a radio frequency channel of the radio frequency chip (RFIC) in the electronic device 100, which is used to generate a radio frequency signal fed into the antenna, or to process the radio frequency signal received by the antenna. A matching circuit (for example, including at least one component) can also be provided between the feeding circuit and the feeding point of the radiator, which can be used to adjust the impedance between the feeding circuit and the feeding point of the radiator. In one embodiment, the first feeding circuit 311 is used to generate a radio frequency signal in the first frequency band fed into the antenna.

[0306] In one embodiment, the first antenna 301 may include a first tuning circuit 313. In one embodiment, the first tuning circuit 313 can be used to switch the resonant point frequency at which the first antenna 301 generates resonance, so that the operating frequency band of the first antenna 301 includes different communication frequency bands at different times / periods. In one embodiment, the first tuning circuit 313 can be used to switch the operating frequency band of the first antenna 301 to include the first frequency band or the second frequency band. In one embodiment, the first tuning circuit 313 can be used to switch the operating mode of the first antenna 301, so that the first antenna 301 can support the first frequency band in its operating frequency band through different operating modes; or so that the first antenna 301 can support the second frequency band in its operating frequency band through different operating modes. It should be understood that switching the operating mode of the antenna can include switching the grounding state of the radiator at the grounding end (for example, the grounding state includes an open circuit, a broken circuit, a semi-open circuit, or a semi-broken circuit state with respect to the floor), or switching the open state of the radiator at the open end (for example, the open state also includes an open circuit, a broken circuit, a semi-open circuit, or a semi-broken circuit state with respect to the floor).

[0307] In one embodiment, the second antenna 302 may include a second tuning circuit 323. The second tuning circuit 323 can be used to switch the resonant point frequency at which the second antenna 302 generates resonance, so that the operating frequency band of the second antenna 302 includes different communication frequency bands at different times / periods. In one embodiment, the second tuning circuit 323 can be used to switch the operating frequency band of the second antenna 302 to include the first frequency band or the second frequency band.

[0308] In one embodiment, the first frequency band may include at least a portion of the frequency band within 1.5 GHz to 4.5 GHz. In one embodiment, when the first antenna 301 or the second antenna 302 operates in the Tiantong satellite system, the first frequency band may include the transmission frequency band therein (for example, 1980 MHz - 2010 MHz). In one embodiment, when the first antenna 301 or the second antenna 302 operates in the Beidou satellite system, the first frequency band may include the transmission frequency band therein (for example, 1610 MHz - 1626.5 MHz). In one embodiment, when the first antenna 301 or the second antenna 302 operates in a low-earth orbit satellite system (such as StarNet), the first frequency band may include the transmission frequency band therein (for example, 1668 MHz - 1675 MHz).

[0309] In one embodiment, the second frequency band may include at least a portion of the frequency band within 1.5 GHz to 4.5 GHz. In one embodiment, when the first antenna 301 or the second antenna 302 operates in the Tiantong satellite system, the second frequency band may include the receiving frequency band therein (for example, 2170 MHz - 2200 MHz). In one embodiment, when the first antenna 301 or the second antenna 302 operates in the Beidou satellite system, the second frequency band may include the receiving frequency band therein (for example, 2483.5 MHz - 2500 MHz). In one embodiment, when the first antenna 301 or the second antenna 302 operates in a low-earth orbit satellite system (such as StarNet), the second frequency band may include the receiving frequency band therein (for example, 1518 MHz - 1525 MHz).

[0310] It should be understood that when the electronic device 100 performs satellite communication, it can communicate with a communication satellite through one antenna inside the electronic device 100. In this case, the antenna can load different elements at different time slots to adjust the resonant point frequency of resonance, so that the antenna can operate in the transmission frequency band and the receiving frequency band of the satellite system at different time slots.

[0311] For the sake of brevity in discussion, in the following embodiments of the present application, it is described by taking the antenna for satellite communication in the electronic device 100 as operating in the first frequency band as an example. When the antenna operates in the second frequency band, it can be understood accordingly and will not be elaborated one by one.

[0312] In one embodiment, the first feeding point 312 on the first radiator 310 (or the second feeding point 322 on the second radiator 320) receives the first radio frequency signal fed by the first feeding circuit 311 (or the second feeding circuit 321). The first radio frequency signal corresponds to the transmission frequency band of the satellite system. Then the first antenna 301 (or the second antenna 302) operates in the transmission frequency band of the satellite system and is used to transmit signals to the communication satellite.

[0313] In one embodiment, the first feeding point 312 on the first radiator 310 (or the second feeding point 322 on the second radiator 320) receives a second radio frequency signal sent by a communication satellite and transmits it to the first feeding circuit 311 (or the second feeding circuit 321). The second radio frequency signal corresponds to the receiving frequency band of the satellite system. Then, the first antenna 301 (or the second antenna 302) operates in the receiving frequency band of the satellite system to receive signals from the communication satellite.

[0314] In one embodiment, at a first time / time period, a first radio frequency signal is fed into the first feeding point 312 (or the second feeding point 322), and the resonant frequency band generated by the first radiator 310 (or the second radiator 320) includes a first frequency band, and the first frequency band may include a transmitting frequency band in at least one satellite communication frequency band.

[0315] In one embodiment, at a first time / time period, the first feeding point 312 (or the second feeding point 322) receives a second radio frequency signal sent by a communication satellite, and the resonant frequency band generated by the first radiator 310 (or the second radiator 320) includes a second frequency band, and the second frequency band may include a receiving frequency band in at least one satellite communication frequency band.

[0316] The first radiation pattern generated by the first antenna 301 is different from the second radiation pattern generated by the second antenna 302.

[0317] Among them, the difference between the first radiation pattern and the second radiation pattern can be understood as the difference between the maximum radiation directions of the first radiation pattern and the second radiation pattern. Or, the difference between the first radiation pattern and the second radiation pattern can be understood as the difference between the null points of the first radiation pattern and the second radiation pattern.

[0318] According to the embodiments of the present application, since the first radiation pattern generated by the first antenna 301 is different from the second radiation pattern generated by the second antenna 302, the electronic device 100 can perform satellite communication through at least one of the first antenna 301 and the second antenna 302. The electronic device 100 can switch between the first antenna 301 and / or the second antenna 302 according to the relative position between the communication satellite and the electronic device 100, so that the communication satellite is always located in an area where the first antenna 301 and / or the second antenna 302 have good radiation characteristics (for example, at least part of the maximum radiation direction of the radiation pattern generated by the antenna overlaps with the target radiation direction), so as to maintain the satellite pointing state with the communication satellite and effectively improve the user experience.

[0319] In one embodiment, the electronic device 100 conducts satellite communication through a single antenna. During a first time / time period, the electronic device 100 conducts satellite communication through the first antenna 301. During a second time / time period, the electronic device 100 conducts satellite communication through the second antenna 302. For example, when the communication satellite is located in an area where the first antenna 301 has good radiation characteristics, the electronic device 100 communicates with the communication satellite through the first antenna 301. For example, the first antenna 301 sends a signal to the communication satellite in a first frequency band and, the first antenna 301 receives a signal sent by the communication satellite in a second frequency band.

[0320] In one embodiment, the electronic device 100 sends a signal to the communication satellite through a single antenna, or, receives signals sent by the communication satellite through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively. During a first time / time period, the electronic device 100 conducts satellite communication through the first antenna 301 in a first frequency band. During a second time / time period, the electronic device 100 conducts satellite communication through the second antenna 302 in the first frequency band. During a third time / time period, the electronic device 100 conducts satellite communication through the first antenna 301 and the second antenna 302 respectively in a second frequency band. For example, when the communication satellite is always located in an area where the first antenna 301 has good radiation characteristics, the electronic device 100 sends a signal to the communication satellite through the first antenna 301 in the first frequency band. Or, the first antenna 301 and the second antenna 302 receive signals sent by the communication satellite respectively in the second frequency band.

[0321] In one embodiment, the electronic device 100 conducts satellite communication through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively. During a first time / time period, the electronic device 100 conducts satellite communication through the first antenna 301 and the second antenna 302 respectively in a first frequency band. During a second time / time period, the electronic device 100 conducts satellite communication through the first antenna 301 and the second antenna 302 respectively in a second frequency band. For example, the electronic device 100 communicates with the communication satellite through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively, including, sending signals to the communication satellite through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively in a first frequency band and, receiving signals sent by the communication satellite through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively in a second frequency band.

[0322] It should be understood that signals received by the electronic device 100 from the communication satellite through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively in the second frequency band can be superimposed by means such as algorithms, so as to enhance the communication quality between the electronic device 100 and the communication satellite.

[0323] In one embodiment, when the electronic device 100 performs satellite communication through a single antenna, the electronic device 100 performs satellite communication by switching between the first antenna 301 and the second antenna 302, and the first feeding circuit 311 and the second feeding circuit 321 may be the same. In one embodiment, the first feeding circuit 311 and the second feeding circuit 321 include the same radio frequency channel in the radio frequency chip. In one embodiment, the circuit portion between the radio frequency channel and the first feeding point 312 in the first feeding circuit 311 and the circuit portion between the radio frequency channel and the second feeding point 322 in the second feeding circuit 321 include at least partially the same electronic components, such as a power amplifier (PA), a low noise amplifier (LNA), and so on.

[0324] In one embodiment, when the electronic device 100 performs satellite communication through multiple antennas, the electronic device 100 performs satellite communication through the first antenna 301 and the second antenna 302 simultaneously, and the first feeding circuit 311 and the second feeding circuit 321 are different. In one embodiment, the first feeding circuit 311 and the second feeding circuit 321 include different radio frequency channels in the radio frequency chip. In one embodiment, the circuit portion between the radio frequency channel and the first feeding point 312 in the first feeding circuit 311 and the circuit portion between the radio frequency channel and the second feeding point 322 in the second feeding circuit 321 include at least partially different electronic components, such as a PA, an LNA, and so on.

[0325] It should be understood that when the electronic device 100 performs satellite communication through multiple antennas, different from an antenna array including multiple radiators (such as a phased array antenna), the first antenna 301 and the second antenna 302 perform satellite communication as independent antennas respectively. For example, the first antenna 301 and the second antenna 302 are independently fed, and there is no need to set a common power splitting and phase shifting circuit for the first antenna 301 and the second antenna 302 so that the radio frequency signals fed into the first antenna 301 and the second antenna 302 have different phase differences.

[0326] Figure 11 It is a schematic diagram of another electronic device 100 provided by an embodiment of the present application.

[0327] As Figure 11 shown, the electronic device 100 may include a first frame 210.

[0328] The first frame 210 includes a first position 201, a second position 202, a third position 203, and a fourth position 204 arranged in sequence. At least a part of the first frame 210 is spaced apart from the floor 300.

[0329] Among them, the first border 210 has an insulating gap or is coupled to the floor 300 at the first position 201. The first border 210 has an insulating gap or is coupled to the floor 300 at the second position 202. The first border 210 has an insulating gap or is coupled to the floor 300 at the third position 203. The first border 210 has an insulating gap or is coupled to the floor 300 at the fourth position 204.

[0330] The first border 210 includes a first side 131 and a second side 132 that intersects the first side 131 at an angle. The length of the first side 131 is less than the length of the second side 132. In one embodiment, the first side 131 can be understood as the short side of the electronic device 100. In one embodiment, the electronic device 100 can also be a foldable electronic device including multiple housings. When the electronic device 100 is folded along the extension direction of the first side 131, the first side 131 can be understood as the short side of the electronic device 100 in the unfolded state. When the electronic device 100 is folded along the extension direction of the second side 132, the first side 131 can be understood as the short side of the electronic device 100 in the folded state. Among them, when the electronic device 100 is folded along the extension direction of the first side 131, it can be understood that the extension direction of the rotation axis is substantially parallel to the extension direction of the first side; when the electronic device 100 is folded along the extension direction of the second side 132, it can be understood that the extension direction of the rotation axis is substantially parallel to the extension direction of the second side.

[0331] It should be understood that the first side 131 can be the top side or the bottom side of the electronic device 100. For the sake of simplicity of discussion, only the case where the first side 131 is the top side of the electronic device 100 is taken as an example for illustration. Among them, the top side / bottom side of the electronic device 100 can be understood as the side at the top / bottom in the normal use state. For example, in a mobile phone, it can be understood as the side at the top / bottom under the desktop and the user interface (GUI).

[0332] In one embodiment, the first position 201 and the second position 202 are located on the first side 131. The third position 203 and the fourth position 204 are located on the second side.

[0333] The electronic device 100 includes a first antenna 301 and a second antenna 302.

[0334] The first radiator 310 of the first antenna 301 includes the conductive part of the first border 210 between the first position 201 and the second position 202. At least part of the first radiator 310 is spaced apart from the floor 300. The first antenna 301 further includes a first feeding circuit 311. The first radiator 310 includes a first feeding point 312, and the first feeding circuit 311 is coupled to the first feeding point 312.

[0335] The second radiator 320 of the second antenna 302 includes a conductive portion of the first frame 210 between the third position 203 and the fourth position 204. At least a portion of the second radiator 320 is spaced apart from the floor 300. The second antenna 302 further includes a second feeding circuit 321, the second radiator 320 includes a second feeding point 322, and the second feeding circuit 321 is coupled to the second feeding point 322.

[0336] It should be understood that the operating frequency bands of the first antenna 301 and the second antenna 302 may both include the first frequency band and / or the second frequency band in the above embodiments. The electronic device 100 may perform satellite communication through the first antenna 301 and / or the second antenna 302.

[0337] In one embodiment, the minimum distance between the second radiator 320 and the first radiator 310 in the extending direction of the second side 132 (e.g., the z direction) is greater than or equal to 20 mm and less than or equal to one half of the length of the second side 132.

[0338] It should be understood that the first radiator 310 and / or the second radiator 320 may be located in the upper half (the area near the top) of the electronic device 100, which is more conducive to the radiation generated by the first antenna 301 and / or the second antenna 302 in the top direction, so that the electronic device 100 has good communication quality with the communication satellite.

[0339] Since the first radiator 310 is located on the top edge of the electronic device 100 and the second radiator 320 is located on the side edge of the electronic device 100. Therefore, the first antenna 301 can generate better radiation in the top direction and has better radiation characteristics. The second antenna 302 can be used to improve the radiation of the electronic device 100 in the upper hemisphere region. For example, the second antenna 302 can be used to enhance the radiation of the electronic device 100 in the top direction on the side of the second radiator 320, and the electronic device 100 can have good communication characteristics within a larger angular range with respect to the top direction.

[0340] In the embodiments of the present application, the top direction can be understood as the direction perpendicular to the first side 131 and pointing from the inside of the electronic device 100 to the first side 131.

[0341] Among them, the upper hemisphere region can be understood as the region where the angle formed with the top direction is less than or equal to 90°. In the coordinate system, it can be understood as the region where the xoy plane faces the positive direction of the z direction.

[0342] In one embodiment, the first radiator 310 can be used to generate a first resonance, and the resonance frequency band of the first resonance includes the first frequency band and / or the second frequency band described above.

[0343] In one embodiment, the first border 210 has a first insulating gap at the first position 201 and is coupled to the floor 300 at the second position 202, as Figure 12 shown.

[0344] In one embodiment, the width of the first insulating gap is greater than or equal to 0.2 mm and less than or equal to 2 mm. It should be understood that, if the process permits, the width of the first insulating gap can be even smaller, or conductive material can be provided inside the first insulating gap and still achieve a similar antenna radiation effect. The widths of the gaps on the borders in the embodiments of the present application can all be within the above range. For the sake of brevity of discussion, they will not be elaborated one by one. Among them, the "width of the insulating gap" can be simply understood as the dimension in the extending direction between two conductive materials (for example, two radiators).

[0345] It should be understood that in the embodiments of the present application, only the first border 210 including the first position 201, the second position 202, the third position 203, and the fourth position 204 arranged in sequence is taken as an example for illustration. In actual production or design, it may not be arranged in this order. For example, the first position 201 can also be located between the second position 202 and the third position 203. At the same time, the first border 210 is coupled to the floor 300 at the first position 201 and has a second insulating gap at the second position 202, and a similar structure (the radiator is a structure with one end being the grounding end and the other end being the open end) can also be formed. For the sake of brevity of discussion, similar structures will not be elaborated one by one and can be correspondingly understood in the embodiments of the present application.

[0346] In one embodiment, the first radiator 310 includes a first connection point 341 and a second connection point 342. The first radiator 310 has a fifth insulating gap between the first connection point 341 and the second connection point 342.

[0347] In one embodiment, the first antenna 301 may further include a first element 331. The first element 331 is coupled and connected between the first connection point 341 and the second connection point 342.

[0348] It should be understood that the first radiator 310 is a structure with one end being the grounding end and the other end being the open end. Moreover, the fifth insulating gap of the first radiator 310 can be regarded as an equivalent capacitance (for example, distributed capacitance) provided on the first radiator 310. This equivalent capacitance can enable the first radiator 310 to form a metamaterial structure. The first radiator 310 with this metamaterial structure can increase the radiation aperture, and the electric field is more dispersed after having this fifth insulating gap. In one embodiment, the dielectric loss near the first radiator 310 forming the metamaterial structure is reduced, so the radiation characteristics of the first antenna 301 (for example, system efficiency and radiation efficiency) can be effectively improved.

[0349] Moreover, by means of a first element 331 coupled between the first connection point 341 and the second connection point 342, the equivalent capacitance value of the fifth insulating gap can be adjusted, thereby adjusting the radiation characteristics of the first antenna 301 (e.g., the resonant point frequency of the first resonance generated by the first radiator 310).

[0350] In one embodiment, the first radiator 310 has a structure with one end being a grounding end and the other end being an open end. Since the region near the open end has a stronger magnetic field, Figure 10 the first tuning circuit shown in FIG. can be disposed near the open end (the second position 202) of the first radiator 310, so that there is a greater adjustment space for the resonant point frequency of the resonance generated by the first antenna 301.

[0351] In one embodiment, the length of the first frame between the connection point of the first tuning circuit and the first radiator 310 and the open end (the second position 202) is less than or equal to 10 mm.

[0352] It should be understood that when the radiators described in the embodiments of the present application have the same structure (the radiator has a structure with one end being a grounding end and the other end being an open end), the settings of the tuning circuits can be understood accordingly and will not be elaborated one by one.

[0353] In one embodiment, the electrical length of the first radiator 310 is greater than three-eighths of the first wavelength.

[0354] It should be understood that the first resonance generated by the first radiator 310 can correspond to the quarter-wavelength mode. Through the fifth insulating gap, the electrical length of the first radiator 310 can be made greater than three-eighths of the first wavelength, and the current on the first radiator 310 is in the same direction (e.g., there is no reverse). The electrical length of the first radiator 310 increases from one-quarter wavelength of the first wavelength to more than three-eighths of the first wavelength, but still operates in the quarter-wavelength mode.

[0355] In this case, the current density on the first radiator 310 is dispersed, and the electric field density between the first radiator 310 and the floor 300 is weakened, thereby reducing the conductor loss and dielectric loss brought by the conductor and dielectric disposed around the first radiator 310 and the first radiator 310, and further improving the radiation characteristics of the first antenna 301. The first radiator 310 increases the radiation aperture, effectively improving the system efficiency and radiation efficiency of the first antenna 301.

[0356] Wherein, the first wavelength can be understood as the vacuum wavelength corresponding to the resonant point frequency of the first resonance generated by the first radiator 310, or can also be understood as the vacuum wavelength corresponding to the center frequency of the resonant frequency band formed by the first resonance generated by the first radiator 310.

[0357] It should be understood that the above wavelengths are all vacuum wavelengths. Since there is a certain conversion relationship between the medium wavelength and the vacuum wavelength, the above vacuum wavelengths can also be converted into medium wavelengths.

[0358] In one embodiment, the length of the first radiator 310 between the first end (ground end, the end at the second position 202) of the first radiator 310 and the fifth insulating slot is less than the length of the first radiator 310 between the second end (open end, the end at the first position 201) of the first radiator 310 and the fifth insulating slot.

[0359] It should be understood that the length of the radiator between one end of the first radiator 310 and the fifth insulating slot can be understood as the length of the conductor part between the end of this end and the fifth insulating slot. For the sake of simplicity of discussion, it can be correspondingly understood in the embodiments of the present application.

[0360] In one embodiment, the length of the first radiator 310 between the first end (ground end, the end at the second position 202) of the first radiator 310 and the fifth insulating slot is less than three-fifths of the length of the first radiator 310 between the second end (open end, the end at the first position 201) of the first radiator 310 and the fifth insulating slot.

[0361] In one embodiment, the length of the first radiator 310 between the first end (ground end, the end at the second position 202) of the first radiator 310 and the fifth insulating slot is less than one-third of the length of the first radiator 310 between the second end (open end, the end at the first position 201) of the first radiator 310 and the fifth insulating slot.

[0362] In one embodiment, the length of the first radiator 310 between the first end (ground end, the end at the second position 202) of the first radiator 310 and the fifth insulating slot is less than one-seventh of the length of the first radiator 310 between the second end (open end, the end at the first position 201) of the first radiator 310 and the fifth insulating slot.

[0363] It should be understandable that the above fifth insulating slot can be located in the region with a larger current of the first radiator 310. The region with a larger current should be understood in terms of the first radiator 310 without the slot (for example, operating in the quarter-wavelength mode). When there is the fifth insulating slot, the electric field intensity of the first radiator 310 becomes weaker, achieving the effect of dispersing the electric field, thereby improving the radiation characteristics of the first antenna 301 (such as system efficiency and radiation efficiency).

[0364] In one embodiment, the first element 331 can be a capacitor or an element equivalent to a capacitor.

[0365] In one embodiment, the equivalent capacitance value of the first element 331 may be less than or equal to a first threshold. The first threshold may be designed according to the resonant point frequency of the first resonance generated by the first radiator 310 (or the center frequency of the second frequency band). When the resonant point frequency of the first resonance is less than or equal to 1 GHz, the first threshold is 10 pF. When the resonant point frequency of the first resonance is greater than 1 GHz, the first threshold is 2 pF.

[0366] In one embodiment, the first element 331 may be an inductor or an element equivalent to an inductor.

[0367] In one embodiment, the equivalent inductance value of the first element 331 may be less than or equal to 5 nH.

[0368] It should be understood that by designing the equivalent capacitance value or the equivalent inductance value of the first element 331 according to the frequencies of the resonant points of different resonances, the current distribution on the first radiator 310 can be made more dispersed, reducing conductor losses and increasing the radiation aperture of the first radiator 310, thereby improving the radiation characteristics of the first antenna 301 (e.g., system efficiency and radiation efficiency).

[0369] In one embodiment, the distance between the first connection point 341 and / or the second connection point 342 and the fifth insulating gap is less than or equal to 5 mm.

[0370] Wherein, the distance between the first connection point 341 and / or the second connection point 342 and the fifth insulating gap can be understood as the minimum distance between the first connection point 341 and / or the second connection point 342 and the conductors on both sides of the fifth insulating gap (the length of the first radiator 310 between the first connection point 341 and / or the second connection point 342 and the fifth insulating gap). When electrically connected to the first connection point 341 and / or the second connection point 342 through a connecting member (e.g., a metal shrapnel), the distance to the fifth insulating gap can be understood as the minimum distance between the center of the part of the connecting member in contact with the connection point and the conductors on both sides of the fifth insulating gap.

[0371] In one embodiment, the first radiator 310 may further include a third connection point 343. The first antenna 301 further includes a second element 332, and the second element 332 is coupled and connected between the third connection point 343 and the ground plane 300.

[0372] It should be understood that when the first radiator 310 is electrically connected to the floor 300 through the second element 332 at the third connection point 343, when the first radiator 310 generates a first resonance, the current on the first radiator 310 is shunted in the area near the third connection point 343. Since the shunting occurs in the area near the third connection point 343, the current density on the first radiator 310 can be dispersed. In one embodiment, the current distribution on the first radiator 310 is relatively more dispersed, thereby reducing the conductor loss of the first radiator 310. In one embodiment, the current distribution on the first radiator 310 is relatively more dispersed, which can increase the radiation aperture of the first radiator 310. Since the conductor loss of the first radiator 310 is reduced and the radiation aperture is increased, the radiation characteristics (such as system efficiency and radiation efficiency) of the first antenna 301 can be improved.

[0373] In one embodiment, the distance between the third connection point 343 and the first connection point 341 and / or the second connection point 342 (for example, the length of the first radiator 310 between the third connection point 343 and the first connection point 341 and / or the second connection point 342) is greater than or equal to 0 mm and less than or equal to 5 mm.

[0374] It should be understood that when the distance between the third connection point 343 and the first connection point 341 and / or the second connection point 342 is equal to 0 mm, the third connection point 343 coincides with the first connection point 341 and / or the second connection point 342.

[0375] In the antenna described in the embodiments of the present application, when the operating mode of the antenna includes the quarter-wavelength mode (one end of the antenna is an open end and the other end is a grounded end), the antenna can have better radiation characteristics (such as radiation efficiency) through a structure similar to that of the Figure 12 shown first antenna 301. For example, Figure 12 the second antenna 302 shown in Figure 15 the second antenna 302 shown in Figure 20 the first antenna 301 shown in (a) in Figure 20 the second antenna 302 shown in (b) in Figure 41 the first antenna 301 and the second antenna 302 shown in Figure 42 the first antenna 301 and the second antenna 302 shown in

[0376] In one embodiment, the first frame 210 has a first insulating gap and a second insulating gap at the first position 201 and the second position 202 respectively, as shown in Figure 13 shown.

[0377] In one embodiment, the distance between the first feeding point 312 and the first position 201 (the length of the first side frame 210 between the first feeding point 312 and the first position 201) is different from the distance between the first feeding point 312 and the second position 202 (the length of the first side frame 210 between the first feeding point 312 and the second position 202).

[0378] It should be understood that the first resonance generated by the first radiator 310 is generated by the line DM mode described in the above embodiment. For the radiation pattern generated by the line DM mode, there is no strong current flowing to the floor 300. Therefore, less current on the floor 300 is excited, and the influence of the floor 300 on the radiation pattern generated by the line DM mode is similar to that of a reflector. Thus, the radiation pattern generated by the line DM mode is mainly oriented towards the top direction of the electronic device 100 (the direction in which the first radiator 310 is away from the floor, for example, the z direction). For the radiation pattern generated by the line CM mode, since the current flowing to the floor 300 in the line CM mode is stronger, more current on the floor 300 is excited, and the floor 300 has a greater influence on the radiation pattern of the antenna. Thus, the radiation pattern generated by the line CM mode is not mainly oriented towards the top direction of the electronic device 100 (the direction in which the first radiator 310 is away from the floor, for example, the z direction).

[0379] Moreover, in the satellite communication frequency band, the efficiency (e.g., radiation efficiency) of the antenna that generates resonance by the line DM mode can meet the requirements of satellite communication. For example, when the first radiator 310 extends linearly, under the action of the co-directional current, both the conductor loss and the dielectric loss are small, so the efficiency (e.g., radiation efficiency) of the first antenna 301 is high. However, for the line CM mode, since the current on the radiator is in the reverse direction and the loss is large, the efficiency (e.g., radiation efficiency) of the antenna that generates resonance by the line CM mode is poor.

[0380] In one embodiment, since the region near the open end has a stronger magnetic field, Figure 10 the tuning circuit shown in the figure can be arranged close to the open end (the first position 201 or the second position 202) on the side of the first radiator 310, so that there is a greater adjustment space for the resonance point frequency of the resonance generated by the first antenna 301. Both ends of the first radiator 310 are open ends, and the first feeding point 312 and the connection point of the tuning circuit to the radiator are respectively located on both sides of the virtual axis of the first radiator 310.

[0381] Among them, the center of the first radiator 310 may be located on the virtual axis, and the lengths of the first radiator 310 on both sides of the virtual axis are the same. It should be understood that the two sides of the virtual axis described in the embodiments of the present application can be understood as the two sides of the plane formed by the virtual axis and the thickness direction of the electronic device 100 (for example, the direction perpendicular to the display screen) (for example, the x direction). At the same time, due to the requirements in production design, the edge of the frame 11 facing the floor 300 (towards the inside of the electronic device 100) is not flat. Therefore, in the embodiments of the application, the virtual axis of the first radiator 310 can be understood as a straight line passing through the center of the first radiator 310 or the first grounding point 351 and perpendicular to the extending direction of the first radiator 310.

[0382] In one embodiment, the length of the frame between the connection point of the tuning circuit and the first radiator 310 and the open end (the first position 201 or the second position 202) is less than or equal to 10 mm.

[0383] It should be understood that when the radiators described in the embodiments of the present application have the same structure (both ends of the radiator are open ends), the involvement of the tuning circuit can be understood accordingly, and will not be elaborated one by one.

[0384] In one embodiment, both ends of the first radiator 310 are open ends, and the first radiator 310 can operate in the half-wavelength mode. The electrical length of the first radiator 310 is half of the first wavelength.

[0385] In one embodiment, the first radiator 310 may further include a first grounding point 351, as Figure 14 shown. The first radiator 310 is coupled to the floor 300 at the first grounding point 351.

[0386] In one embodiment, the first grounding point 351 may be located in the central region of the first radiator 310. The central region can be understood as the region within 5 mm from the center of the first radiator 310, and the lengths of the first radiator 310 on both sides of the center are the same.

[0387] It should be understood that by increasing the structural symmetry of the first antenna 301, the first antenna 301 can have better communication performance.

[0388] In one embodiment, grounding can be achieved through a grounding member at the first grounding point 351. The width of the grounding member connected to the first frame 210 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0389] In one embodiment, when the grounding member includes at least a part of the central region of the first radiator 310 described above, it can be considered that the first grounding point 351 is located in the central region of the first radiator 310.

[0390] It should be understood that when the first radiator 310 is coupled to the floor 300 at the first grounding point 351, the first radiator 310 can also generate a second resonance by the line CM mode, and the second resonance can be used to improve the radiation characteristics (e.g., radiation efficiency) of the first antenna 301 in the first frequency band and / or the second frequency band.

[0391] In one embodiment, the length of the first radiator 310 between the first grounding point 351 and the first position 201 is greater than or equal to one-fourth of the length of the first radiator 310, and the length of the first radiator 310 between the first grounding point 351 and the second position 202 is greater than or equal to one-fourth of the length of the first radiator 310.

[0392] It should be understood that the first grounding point 351 can be arranged in a region close to the center of the first radiator 310 to better excite the first radiator 310 to generate the line CM mode and the line DM mode. And when the first grounding point 351 can be arranged in a region close to the center of the first radiator 310, it is more convenient to adjust the frequency difference between the resonances generated by the line CM mode and the line DM mode, so that the first antenna 301 has better radiation characteristics. For the sake of brevity of discussion, the grounding points on the radiators described in the embodiments of the present application can be understood accordingly and will not be elaborated one by one.

[0393] In one embodiment, the resonance point frequency of the first resonance can be higher than the resonance point frequency of the second resonance. The ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance can be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance can be greater than or equal to 1.3 and less than or equal to 1.5.

[0394] In one embodiment, the frequency difference between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance can be greater than or equal to 100 MHz and less than or equal to 500 MHz.

[0395] It should be understood that in the first frequency band (or the second frequency band), the first antenna 301 can operate in the line DM mode. The second resonance can be used to improve the radiation characteristics (e.g., radiation efficiency) of the first antenna 301 in the resonance frequency band of the first resonance.

[0396] In one embodiment, the resonance point frequency of the first resonance can be higher than the resonance point frequency of the second resonance. The ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance can be less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band is greater than the resonance point frequency of the second resonance and less than the resonance point frequency of the first resonance.

[0397] It should be understood that in the first frequency band (or the second frequency band), the first antenna 301 can operate in a hybrid mode of the line CM mode and the line DM mode, and the radiation is jointly generated by the line CM mode and the line DM mode. The first antenna 301 simultaneously has partial radiation characteristics of the line CM mode and partial radiation characteristics of the line DM mode.

[0398] In one embodiment, the ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance is less than or equal to 1.2. In one embodiment, the frequency difference between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance is less than or equal to 300 MHz.

[0399] In one embodiment, the first antenna 301 includes a first switch branch 361, a second switch branch 362, and a first switch 360, as Figure 15 shown.

[0400] The first radiator 310 includes a fourth connection point 344. The first switch branch 361 and the second switch branch 362 are coupled between the fourth connection point 344 and the ground plane 300 through the first switch 360. In one embodiment, the first connection port of the first switch 360 is coupled to the first switch branch 361, and the second connection port of the first switch 360 is coupled to the second switch branch 362.

[0401] For ease of understanding, the first switch branch 361 and the second switch branch 362 can be regarded as being arranged in parallel. In one embodiment, the first switch branch 361 and the second switch branch 362 are connected in parallel between the ground plane 300 and the fourth connection point 344. In one embodiment, both the first switch branch 361 and the second switch branch 362 are connected in parallel between the ground plane 300 and the fourth connection point 344 through the first switch 360.

[0402] It should be understood that the switches described in this application, for example, the "first switch" may include one or more switch devices; the connection points in this application, for example, the "fourth connection point" may include one or more connection points. In one embodiment, the first switch branch 361 can be coupled between the ground plane 300 and the first radiator 310 through one switch device in the first switch and one connection point in the fourth connection point 344; the second switch branch 362 can be coupled between the ground plane 300 and the first radiator 310 through another switch device in the first switch and another connection point in the fourth connection point 344. In the embodiments of this application, the switch is only used as a switch to switch to different switch branches coupled to the radiator / parasitic stub, and does not limit its specific position and specific form.

[0403] It should be understood that in the embodiments of the present application, the switching branch can be understood as the circuit between the switch and the connection point (for example, the fourth connection point 344) or the floor 300. The switch can be switched to different switching branches, so that the equivalent capacitance, equivalent resistance or equivalent inductance coupled to the connection point is different.

[0404] In one embodiment, the first tuning circuit described in the above embodiment may include a first switching branch 361, a second switching branch 362, and a first switch 360. The first tuning circuit can also be used to adjust the current distribution on the first radiator 310 and the floor 300. In one embodiment, the first antenna 301 may further include a third switching branch, and the third switching branch can be used to adjust the resonant point frequency of the resonance generated by the first antenna 301, so that the first antenna 301 operates in different satellite communication frequency bands. For example, when the fourth connection point 344 is coupled to the first switching branch 361 or the second switching branch 362 through the first switch 360, the resonant frequency band of the resonance generated by the first radiator 310 includes the first frequency band; when the fourth connection point 344 is coupled to the third switching branch through the first switch 360, the resonant frequency band of the resonance generated by the first radiator 310 includes the second frequency band.

[0405] In one embodiment, the switching branch may include one or more elements, and the multiple elements can be connected in series or in parallel to achieve different equivalent capacitance values and / or equivalent inductance values and / or equivalent resistance values. In one embodiment, the switching branch may also include a switch, and the equivalent capacitance value and / or equivalent inductance value and / or equivalent resistance value in different states of the switching branch can be switched through the switch.

[0406] In one embodiment, the switching branch may not include elements. The switching branch can be used to determine the boundary conditions at the fourth connection point. For example, the switching branch is in an open state. When the common port of the switch is connected to the switching branch, the fourth connection point 344 is in an open state (not coupled to the floor 300 through a device). Or, the switching branch is in a short-circuit state. When the common port of the switch is connected to the switching branch, the fourth connection point 344 is in a short-circuit state (electrically connected to the floor 300 through a stub, and no other elements are provided). For the sake of brevity of discussion, in Figure 14 the illustrated electronic device 100, only the first switching branch 361 including equivalent elements and the second switching branch 362 including equivalent elements are taken as examples for illustration.

[0407] In one embodiment, the first feeding point 312 and the fourth connection point 344 are respectively located on both sides of the virtual axis of the first radiator 310. At this time, the first radiator 310 may or may not include the first grounding point 351.

[0408] When the fourth connection point 344 is coupled to the first switch branch 361. For example, the common port of the first switch 360 is coupled to the first connection port of the first switch 360, and the first switch branch 361 is coupled to the fourth connection point 344. The resonant frequency band of the resonance generated by the first radiator 310 includes the first frequency band (or the second frequency band).

[0409] When the fourth connection point 344 is coupled to the second switch branch 362. For example, the common port of the first switch 360 is coupled to the second connection port of the first switch 360, and the second switch branch 362 is coupled to the fourth connection point 344. The resonant frequency band of the resonance generated by the first radiator 310 includes the above-mentioned first frequency band (or the second frequency band).

[0410] It should be understood that when the fourth connection point 344 is coupled to the first switch branch 361 or the second switch branch 362 through the first switch 360, the resonant frequency band of the resonance generated by the first radiator 310 can include the first frequency band.

[0411] In an embodiment of the present application (for example, in Figure 14 the electronic device 100 shown), taking the first antenna 301 being in the same working state as an example for illustration. Among them, the same working state can be understood as that the working frequency band of the first antenna 301 either includes the first frequency band or the second frequency band, and the first antenna 301 can communicate in the corresponding frequency band when the first switch 360 is coupled to the first switch branch 361 or the second switch branch 362.

[0412] In one embodiment, the first switch branch 361 and the second switch branch 362 can be used to adjust the current distribution on the first radiator 310 and the ground plane 300.

[0413] In one embodiment, the fourth connection point 344 is located on the first side of the virtual axis, and the first feeding point 312 is located on the second side of the virtual axis.

[0414] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the case where the fourth connection point 344 is located on the first side of the virtual axis and the first feeding point 312 is located on the second side of the virtual axis is taken as an example for illustration. In actual production or application, the fourth connection point 344 can also be located on the second side of the virtual axis, and the first feeding point 312 can also be located on the first side of the virtual axis. Similarly, it can be understood accordingly.

[0415] In one embodiment, the first switch branch 361 is coupled to the fourth connection point 344, the first antenna 301 operates in the first frequency band or the second frequency band, and the current (for example, current intensity, current density) on the ground plane 300 on the first side of the virtual axis is greater than the current on the ground plane 300 on the second side of the virtual axis.

[0416] In one embodiment, the first switch branch 361 is coupled to the fourth connection point 344, the first antenna 301 operates in a first frequency band or a second frequency band, and the current (e.g., current intensity, current density) on the first radiator 310 on the first side of the virtual axis is greater than the current on the first radiator 310 on the second side of the virtual axis.

[0417] In one embodiment, the second switch branch 362 is coupled to the fourth connection point 344, the first antenna 301 operates in a first frequency band or a second frequency band, and the current (e.g., current intensity, current density) on the ground plane 300 on the first side of the virtual axis is less than the current on the ground plane 300 on the second side of the virtual axis.

[0418] In one embodiment, the second switch branch 362 is coupled to the fourth connection point 344, the first antenna 301 operates in a first frequency band or a second frequency band, and the current (e.g., current intensity, current density) on the first radiator 310 on the first side of the virtual axis is less than the current on the first radiator 310 on the second side of the virtual axis.

[0419] It should be understood that the current on the ground plane 300 described in the embodiments of the present application can be understood as the current near the edge of the ground plane 300 close to the radiator / parasitic stub, for example, the current within 30 mm from the edge.

[0420] It should be understood that when the current (e.g., current intensity, current density) on the ground plane 300 on the first side of the virtual axis is greater than the current on the ground plane 300 on the second side of the virtual axis, the first radiation pattern generated by the first antenna 301 deflects towards the second side. When the current (e.g., current intensity, current density) on the ground plane 300 on the first side of the virtual axis is less than the current on the ground plane 300 on the second side of the virtual axis, the first radiation pattern generated by the first antenna 301 deflects towards the first side.

[0421] Therefore, by switching the switch branch coupled to the fourth connection point 344, the maximum radiation direction of the first radiation pattern generated by the first antenna 301 can be deflected, so that the first antenna 301 can have good radiation characteristics in a larger area.

[0422] In one embodiment, both the first switch branch 361 and the second switch branch 362 can be capacitive. The equivalent capacitance value of the first switch branch 361 and the equivalent capacitance value of the second switch branch 362 can both be less than or equal to 2 pF.

[0423] It should be understood that when the first switch branch 361 and the second switch branch 362 are capacitive, the equivalent capacitance value of the first switch branch 361 is less than the equivalent capacitance value of the second switch branch 362.

[0424] When the second switch branch 362 is coupled to the fourth connection point 344, compared with the first switch branch 361 being coupled to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis decreases, and the current on the floor 300 on the second side of the virtual axis increases.

[0425] When the first switch branch 361 is coupled to the fourth connection point 344, compared with the second switch branch 362 being coupled to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis increases, and the current on the floor 300 on the second side of the virtual axis decreases.

[0426] In one embodiment, the first switch branch 361 and the second switch branch 362 can both be inductive. The equivalent inductance value of the first switch branch 361 and the equivalent inductance value of the second switch branch 362 can both be greater than or equal to 5 nH and less than or equal to 100 nH.

[0427] It should be understood that when the first switch branch 361 and the second switch branch 362 are inductive, the equivalent inductance value of the first switch branch 361 is less than the equivalent inductance value of the second switch branch 362.

[0428] When the second switch branch 362 is coupled to the fourth connection point 344, compared with the first switch branch 361 being coupled to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis decreases, and the current on the floor 300 on the second side of the virtual axis increases.

[0429] When the first switch branch 361 is coupled to the fourth connection point 344, compared with the second switch branch 362 being coupled to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis increases, and the current on the floor 300 on the second side of the virtual axis decreases.

[0430] In one embodiment, the first switch branch 361 can be capacitive and the second switch branch 362 can be inductive.

[0431] When the second switch branch 362 is coupled to the fourth connection point 344, compared with the first switch branch 361 being coupled to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis decreases, and the current on the floor 300 on the second side of the virtual axis increases.

[0432] When the first switch branch 361 is coupled to the fourth connection point 344, compared with the second switch branch 362 being coupled to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis increases, and the current on the floor 300 on the second side of the virtual axis decreases.

[0433] In one embodiment, when the first switch branch 361 is coupled to the fourth connection point 344, the frequency difference between the resonance point frequencies of the first resonance and the second resonance generated by the first antenna 301 is the first frequency difference. When the second switch branch 362 is coupled to the fourth connection point 344, the frequency difference between the resonance point frequencies of the first resonance and the second resonance generated by the first antenna 301 is the second frequency difference. The first frequency difference is less than the second frequency difference.

[0434] In one embodiment, the first frequency difference is less than the first threshold, and the second frequency difference is greater than the first threshold. In one embodiment, the first threshold is 300 MHz. In one embodiment, the first threshold is 250 MHz. In one embodiment, the first threshold is 200 MHz. In one embodiment, the first threshold is 150 MHz.

[0435] It should be understood that the first switch branch 361 and the second switch branch 362 can also be used to adjust the frequency difference between the resonance point frequencies of the resonance generated by the line CM mode and the resonance generated by the line DM mode.

[0436] When the second switch branch 362 is coupled to the fourth connection point 344, compared with the first switch branch 361 being coupled to the fourth connection point 344, the frequency difference between the resonance point frequencies of the resonance generated by the line CM mode and the resonance generated by the line DM mode increases, the current on the first side of the virtual axis on the floor 300 weakens, and the current on the second side of the virtual axis on the floor 300 strengthens. When the first switch branch 361 is coupled to the fourth connection point 344, compared with the second switch branch 362 being coupled to the fourth connection point 344, the frequency difference between the resonance point frequencies of the resonance generated by the line CM mode and the resonance generated by the line DM mode decreases, the current on the first side of the virtual axis on the floor 300 strengthens, and the current on the second side of the virtual axis on the floor 300 weakens.

[0437] In one embodiment, the first frequency difference is less than the second frequency difference. In one embodiment, the difference between the first frequency difference and the second frequency difference is greater than or equal to 100 MHz. In one embodiment, the difference between the first frequency difference and the second frequency difference is greater than or equal to 50 MHz.

[0438] It should be understood that when the difference between the first frequency difference and the second frequency difference is within the above range, and the fourth connection point 344 is coupled to the first switch branch 361 or the second switch branch 362 respectively, the current on the floor 300 on the first side of the virtual axis is more different from the current on the floor 300 on the second side of the virtual axis, so that the difference between the first radiation pattern and the second radiation pattern is greater (for example, the angle between the maximum radiation directions increases), and the width of the radiation beam of the first antenna 301 can be further broadened. The first antenna 301 has a wider beam width, enabling the first antenna 301 to have good communication characteristics within a wider angle range (the angle formed with the top direction).

[0439] In one embodiment, the length of the first side frame 210 between the first feeding point 312 and the third position 203 is less than the length of the first side frame 210 between the fourth connection point 344 and the third position 203.

[0440] It should be understood that the first feeding point 312 can be located on the side close to the second antenna 302. In one embodiment, the first feeding circuit 311 and the second feeding circuit 321 can be generated by different radio frequency channels of the same radio frequency chip. When the first feeding point 312 is close to the second feeding point 322, the current transmission paths from the radio frequency chip to the first feeding point 312 and the second feeding point 322 are shorter, which can reduce the loss caused by line transmission and improve the radiation characteristics of the antenna.

[0441] Moreover, since the area near the feeding point usually has a strong current, when the first feeding point 312 can be located on the side close to the second antenna 302, it is easier to enhance the current on the floor 300 on the second side of the virtual axis, causing the maximum radiation direction of the radiation pattern generated by the first antenna 301 to deflect away from the second antenna 302, making the difference between the radiation patterns of the first antenna 301 and the second antenna 302 greater, so that the electronic device 100 has good communication characteristics within a wider angle range (the angle formed with the top direction).

[0442] It should be understood that for the antenna described in the embodiments of the present application, when the operating mode of the antenna includes the line DM mode (the two ends of the antenna are open ends), the switching between the first radiation pattern and the second radiation pattern can be realized through a structure similar to that of the first antenna 301 shown in Figure 15 For example, Figure 13 the first antenna 301 and the second antenna 302 shown in Figure 14 the first antenna 301 and the second antenna 302 shown in Figure 20 the second antenna 302 shown in (a) in Figure 20 the first antenna 301 shown in (b) and (c) in Figure 25 the first antenna 301 shown in Figure 31The first antenna 301 shown in Figure 38 The first antenna 301 and the second antenna 302 shown in Figure 39 The first antenna 301 and the second antenna 302 shown in, etc. For the sake of brevity of discussion, they will not be elaborated one by one.

[0443] In one embodiment, the second radiator 320 can be used to generate a third resonance, and the resonance frequency band of the third resonance includes the above-mentioned first frequency band and / or second frequency band.

[0444] In one embodiment, the first frame 210 is coupled to the floor 300 at the third position 203 and has a fourth insulating gap at the fourth position 204, as Figure 15 shown.

[0445] It should be understood that one end of the second radiator 320 is a grounded end and the other end is an open end, forming a structure similar to an inverted F-shaped antenna or a left-handed antenna. The left-handed antenna can, for example, conform to an antenna with a composite right and left hand (CRLH) transmission line structure.

[0446] When the second radiator 320 forms a structure similar to an inverted F-shaped antenna, the second feeding point 322 is close to the grounded end, and the distance between the second feeding point 322 and the grounded end (the length of the second radiator 320 between the second feeding point 322 and the third position 203) is less than or equal to one-half of the length of the second radiator 320.

[0447] When the second radiator 320 forms a structure similar to a left-handed antenna, the second feeding point 322 is close to the open end, and the distance between the second feeding point 322 and the grounded end (the length of the second radiator 320 between the second feeding point 322 and the third position 203) is greater than or equal to one-half of the length of the second radiator 320. When the second feeding point 322 is close to the open end, it is beneficial to realize the miniaturization of the second radiator 320. The second feeding circuit 321 is coupled to the second feeding point 322 by a capacitor to better excite the second radiator 320.

[0448] For the sake of brevity of discussion, when forming a structure similar to an inverted F-shaped antenna or a left-handed antenna, it can be correspondingly understood in the application embodiments and will not be elaborated one by one.

[0449] In one embodiment, the third resonance generated by the second radiator 320 can correspond to a quarter-wavelength mode. The electrical length of the second radiator 320 can be one-fourth of the second wavelength, and the second wavelength is the wavelength corresponding to the third resonance.

[0450] In one embodiment, the first frame 210 further includes a fifth position 205, and the fourth position 204 is located between the third position 203 and the fifth position 205. The first frame 210 is coupled to the floor 300 at the fifth position 205.

[0451] In one embodiment, the second antenna 302 further includes a first parasitic stub 330. The first parasitic stub 330 includes a conductive portion of the first frame 210 between the fifth position 205 and the fourth position 204.

[0452] It should be understood that the first parasitic stub 330 can be used to improve the radiation characteristics of the second antenna 302 in the first frequency band and / or the second frequency band.

[0453] In one embodiment, when the parasitic resonance generated by the first parasitic stub 330 is close to the second resonance generated by the second radiator 320 (the frequency difference between the resonance points of the parasitic resonance and the resonance points of the second resonance is less than or equal to 300 MHz and greater than or equal to 100 MHz), the first parasitic resonance 330 can be used to improve the radiation efficiency of the second antenna 302 in the first frequency band and / or the second frequency band.

[0454] In one embodiment, when the parasitic resonance generated by the first parasitic stub 330 is far from the second resonance generated by the second radiator 320 (the frequency difference between the resonance points of the parasitic resonance and the resonance points of the second resonance is greater than or equal to 300 MHz), the first parasitic resonance 330 can be used to improve the beam width of the second antenna 302 in the first frequency band and / or the second frequency band. The current on the first parasitic stub 330 is in the same direction as the current on the second radiator 320, which can enable the second antenna 302 to have better communication characteristics within a larger angular range on one side of the first parasitic stub 330 and in the top direction.

[0455] In one embodiment, the third position 203 is located between the fourth position 204 and the fifth position 205. The first frame 210 has an insulating gap at the fifth position 205.

[0456] It should be understood that in the above embodiment, the first parasitic stub 330 and the second radiator 320 are opposite and non-contact through the fourth insulating gap (the open ends are close to each other). In actual production or design, the first parasitic stub 330 and the second radiator 320 can also be connected through the third position 203 (the grounded ends are close to each other).

[0457] It should be understood that the antennas described in the present application can all include parasitic stubs, and the parasitic stubs can be used to improve the radiation characteristics of the antennas (such as beam width, radiation efficiency, etc.). For the sake of simplicity of discussion, they will not be elaborated one by one.

[0458] In one embodiment, the first frame 210 is coupled to the floor 300 at the third position 203 and has a fourth insulation gap at the fourth position 204. The second radiator 320 includes a fifth connection point 345 and a sixth connection point 346. The second radiator 320 has a sixth insulation gap between the fifth connection point 345 and the sixth connection point 346, as Figure 12 shown.

[0459] In one embodiment, the second antenna 302 further includes a third element 333. The third element 333 is coupled between the fifth connection point 345 and the sixth connection point 346.

[0460] It should be understood that the second radiator 320 has a structure with one end being the ground end and the other end being the open end. Similarly, Figure 12 in the electronic device 100 shown, the second radiator 320 can also form a metamaterial structure. For the sake of brevity of discussion, it will not be elaborated one by one and can be understood with reference to the metamaterial structure in the above embodiments.

[0461] In one embodiment, the first frame 210 has a third insulation gap and a fourth insulation gap at the third position 203 and the fourth position 204 respectively, as Figure 13 shown.

[0462] In one embodiment, the distance between the second feeding point 322 and the third position 203 (the length of the first frame 210 between the second feeding point 322 and the third position 203) is different from the distance between the second feeding point 322 and the fourth position 204 (the length of the first frame 210 between the second feeding point 322 and the fourth position 204).

[0463] It should be understood that the third resonance generated by the second radiator 320 is generated by the line DM mode described in the above embodiments. Similarly, it can be understood with reference to the corresponding description in the above embodiments.

[0464] In one embodiment, both ends of the second radiator 320 are open ends, and the second radiator 320 can operate in the half-wavelength mode. The electrical length of the second radiator 320 is half of the second wavelength.

[0465] In one embodiment, the second radiator 320 may further include a second grounding point 352, as Figure 14 shown. The second radiator 320 is coupled to the floor 300 at the second grounding point 352.

[0466] In one embodiment, the second grounding point 352 may be located in the central region of the second radiator 320. The central region can be understood as the region within 5 mm from the center of the second radiator 320, and the lengths of the second radiator 320 on both sides of the center are the same.

[0467] It should be understood that by increasing the structural symmetry of the second antenna 302, the second antenna 302 can have better communication performance.

[0468] In one embodiment, grounding can be achieved through a grounding member at the second grounding point 352. The width of the connection between the grounding member and the first frame 210 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0469] In one embodiment, when the grounding member includes at least part of the central region of the second radiator 320, it can be considered that the second grounding point 352 is located in the central region of the second radiator 320.

[0470] It should be understood that when the second radiator 320 is coupled to the floor 300 at the second grounding point 352, the second radiator 320 can also generate a fourth resonance by the line CM mode, and the fourth resonance can be used to improve the radiation characteristics (e.g., radiation efficiency) of the second antenna 302 in the first frequency band and / or the second frequency band.

[0471] In one embodiment, the resonance point frequency of the third resonance can be higher than the resonance point frequency of the fourth resonance. The ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance can be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance can be greater than or equal to 1.3 and less than or equal to 1.5.

[0472] In one embodiment, the frequency difference between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance can be greater than or equal to 100 MHz and less than or equal to 500 MHz.

[0473] It should be understood that in the first frequency band (or the second frequency band), the second antenna 302 can operate in the line DM mode. The fourth resonance can be used to improve the radiation characteristics (e.g., radiation efficiency) of the second antenna 302 in the resonance frequency band of the third resonance.

[0474] In one embodiment, the resonance point frequency of the third resonance can be higher than the resonance point frequency of the fourth resonance. The ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance can be less than or equal to 1.3. In one embodiment, the central frequency of the first frequency band is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance.

[0475] It should be understood that in the first frequency band (or the second frequency band), the second antenna 302 can operate in a hybrid mode of the line CM mode and the line DM mode, and radiation is jointly generated by the line CM mode and the line DM mode. The second antenna 302 simultaneously has partial radiation characteristics of the line CM mode and partial radiation characteristics of the line DM mode.

[0476] In one embodiment, the ratio between the resonant point frequencies of the third resonance and the fourth resonance is less than or equal to 1.2. In one embodiment, the frequency difference between the resonant point frequencies of the first resonance and the second resonance is less than or equal to 300 MHz.

[0477] In one embodiment, the first antenna 301 and the second antenna 302 included in the electronic device 100 may be Figures 12 to 15 any one of the first antennas 301 and any one of the second antennas 302 shown in, or a combination of any first antenna 301 and second antenna 302.

[0478] It should be understood that when the difference between the first radiation pattern generated by the first antenna 301 and the second radiation pattern generated by the second antenna 302 is large, the electronic device 100 can perform satellite communication by switching between the first antenna 301 and the second antenna 302, or can perform satellite communication simultaneously through the first antenna 301 and the second antenna 302 to have good communication quality in a larger area.

[0479] For example, when the first antenna 301 and the second antenna 302 are Figure 13 or Figure 14 as shown in (the radiator does not include the ground point as shown in Figure 14 or the radiator includes the ground point as shown in Figure 14 ), the working mode of the first antenna 301 located at the top is the line DM mode, and the electrical length of the stub is about half a wavelength. It is fed at one end of the first radiator 310, and the other end of the first radiator 310 is tuned through a capacitive or inductive device. The middle area of the first radiator 310 can be grounded or not. When the middle area of the first radiator 310 is grounded, by tuning the resonance generated by the line CM mode before the resonance generated by the line DM mode, the resonance during the operation of the first antenna is exactly in the line DM mode, and the first antenna 301 has the best radiation efficiency and an end-fire radiation pattern in the top direction. Similarly, the second antenna 302 located at the waist is also fed at one end of the second radiator 320, and the other end of the second radiator 320 is tuned through a capacitive or inductive device. The middle area of the second radiator 320 can be grounded or not. When the middle area of the second radiator 320 is grounded, by tuning the resonance generated by the line CM mode before the resonance generated by the line DM mode, the resonance during the operation of the second antenna is exactly in the line DM mode, achieving a radiation pattern towards one side. Since both the first antenna 301 and the second antenna 302 can achieve coverage of the upper hemisphere (upper hemisphere region) and have a certain degree of radiation pattern complementarity, a wide beam coverage can be achieved by combining the two antennas.

[0480] When the first antenna 301 and the second antenna 302 are Figure 14In the first antenna 301 and the second antenna 302 shown in FIG, there is a coverage null on the left side of the combined directional pattern of the first antenna 301 and the second antenna 302. In order to enhance the coverage on the left side, an unbalanced linear DM mode ( Figure 15 The first antenna 301 shown in FIG. 1 is a first antenna 301 shown in FIG. 1 . That is, by adjusting the resonance generated by the line CM mode to a position more forward of the resonance generated by the line DM mode, the current generated by the line DM mode is biased to the right, and the current mode presents a distribution of strong right and weak left, and its corresponding directional pattern will be biased to the left. Therefore, by combining this directional pattern with the second antenna 302 located at the waist, a directional pattern covering the top side (top direction), the left side (left side of the top direction) and the right top direction (side) can be obtained. Therefore, by combining the two antennas, better wide beam coverage can be achieved.

[0481] In one embodiment, the structure of the first radiator 310 is the same as the structure of the second radiator 320 .

[0482] The same structure can be understood as the same boundary conditions, for example, one end is a grounded end and the other end is an open end, or both ends are open ends.

[0483] It should be understood that when the first antenna 301 and the second antenna 302 have good symmetry, the electronic device 100 can have good communication quality in a larger area by switching the first antenna 301 and the second antenna 302 for satellite communication, or by simultaneously performing satellite communication through the first antenna 301 and the second antenna 302.

[0484] Figure 16 and Figure 17 yes Figure 14 The simulation results of the first antenna 301 and the second antenna 302 in the electronic device 100 are shown. Figure 16 yes Figure 14 The simulation results of S parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 are shown. Figure 17 yes Figure 14 The simulation results of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 are shown.

[0485] It should be understood that for the sake of simplicity, only the first antenna 301 and the second antenna 302 in the electronic device 100 are used as examples. Figures 12 to 15 The combination shown in is used as an example for explanation. In actual production or design, the first antenna 301 in the combination can be Figures 12 to 15 Any one of the first antennas shown in , and the second antenna 302 in the combination can be Figures 12 to 15 For the sake of brevity, any second antenna shown in FIG. 1 will not be described in detail one by one.

[0486] As Figure 16 shown, the first antenna (S11) can resonate near 2.05 GHz and near 2.2 GHz. Resonating near 2.05 GHz can correspond to the second resonance in the above embodiments, and resonating near 2.2 GHz can correspond to the first resonance in the above embodiments. The resonance frequency band of the first resonance can include the above second frequency band.

[0487] The second antenna (S22) can resonate near 1.95 GHz and near 2.15 GHz. Resonating near 1.95 GHz can correspond to the fourth resonance in the above embodiments, and resonating near 2.15 GHz can correspond to the third resonance in the above embodiments. The resonance frequency band of the third resonance can include the above second frequency band.

[0488] In the second frequency band (e.g., 2170 MHz - 2200 MHz), the isolation (S12 / S21) between the first antenna and the second antenna is greater than 15 dB, and there is good isolation between the first antenna and the second antenna.

[0489] As Figure 17 shown, when only the first antenna works in the electronic device, in the second frequency band (e.g., 2170 MHz - 2200 MHz), the radiation efficiency of the first antenna is about -2.1 dB.

[0490] When only the second antenna works in the electronic device, in the second frequency band (e.g., 2170 MHz - 2200 MHz), the radiation efficiency of the second antenna is about -2.2 dB.

[0491] When the first antenna and the second antenna work simultaneously in the electronic device, in the second frequency band (e.g., 2170 MHz - 2200 MHz), the radiation efficiency of the first antenna drops by about 0.4 dB, and the radiation efficiency of the second antenna drops by about 0.4 dB.

[0492] Figure 18 And Figure 19 are Figure 14 the radiation patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown. Among them, Figure 18 is Figure 14 the first radiation pattern generated by the first antenna 301 in the electronic device 100 shown. Figure 19 is Figure 14 the second radiation pattern generated by the second antenna 302 in the electronic device 100 shown.

[0493] As Figure 18 shown, the maximum radiation direction of the first radiation pattern generated by the first antenna faces the top direction (e.g., z direction) of the electronic device.

[0494] AsFigure 19 As shown, the maximum radiation direction of the second radiation pattern generated by the second antenna faces the side direction of the electronic device (the direction perpendicular to the second side, for example, the y direction).

[0495] It should be understood that the angle between the maximum radiation direction of the first radiation pattern generated by the first antenna and the maximum radiation direction of the second radiation pattern generated by the second antenna is relatively large. The electronic device can switch the first antenna or the second antenna (or, the first antenna and the second antenna work simultaneously) to keep the communication satellite in the area where the electronic device has better radiation characteristics all the time.

[0496] Figure 20 It is a schematic diagram of another electronic device 100 provided by an embodiment of the present application.

[0497] As Figure 20 shown, the electronic device 100 may include a first housing 211, a second housing 212, and a first rotating shaft 213.

[0498] Among them, the first housing 211 includes a first frame 210, and at least part of the first frame 210 is spaced apart from the floor 300. The second housing 212 includes a second frame 220, and at least part of the second frame 220 is spaced apart from the floor 300.

[0499] The first rotating shaft 213 is located between the first housing 211 and the second housing 212, and the first rotating shaft 213 is respectively rotatably connected to the first housing 211 and the second housing 212, so that the first housing 211 and the second housing 212 can rotate relative to each other.

[0500] It should be understood that in the electronic device 100 shown in Figure 20 , the electronic device 100 is a foldable electronic device. The first rotating shaft 213 is directly connected to the first housing 211 and the second housing 212 respectively, so that the first housing 211 and the second housing 212 can rotate relative to each other. In addition, "the first rotating shaft 213 is respectively rotatably connected to the first housing 211 and the second housing 212" includes this situation: the first rotating shaft 213 can be rotatably connected to the first or second housing through one or more second rotating shafts and one or more intermediate housings. For example, in one embodiment, the electronic device 100 may further include a first rotating shaft and a second rotating shaft, and one or more intermediate housings located between the first rotating shaft and the second rotating shaft. The first rotating shaft is located between the first housing 211 and the intermediate housing, and the first rotating shaft is respectively rotatably connected to the first housing 211 and the intermediate housing, so that the first housing 211 and the intermediate housing can rotate relative to each other. The second rotating shaft is located between the intermediate housing and the second housing 212, and the first rotating shaft 213 is respectively rotatably connected to the intermediate housing and the second housing 212, so that the intermediate housing and the second housing 212 can rotate relative to each other.

[0501] It should be understood thatFigure 20 The shown electronic device 100 and Figures 11 to 15 the shown electronic device 100 only differ in whether the electronic device 100 can be folded.

[0502] As Figure 20 shown, the electronic device 100 includes a first antenna 301 and a second antenna 302.

[0503] Among them, the first antenna 301 can be Figures 12 to 15 any one of the first antennas shown in Figures 12 to 15 The second antenna 302 can be

[0504] In one embodiment, the first antenna 301 can be a metamaterial structure (for example, Figure 12 the first antenna 301 shown), and the second antenna 302 can be a structure with open ends at both ends and including a second ground point 352 (for example, Figure 14 the second antenna 302 shown), as Figure 20 shown in (a) of

[0505] In one embodiment, the first antenna 301 can be a structure with open ends at both ends and not including a first ground point 351 (for example, Figure 13 the first antenna 301 shown), and the second antenna 302 can be a metamaterial structure (for example, Figure 12 the second antenna 302 shown), as Figure 20 shown in (b) of

[0506] In one embodiment, the first antenna 301 can be a structure with open ends at both ends and including a first ground point 351 (for example, Figure 14 the first antenna 301 shown), and the second antenna 302 can be a structure with open ends at both ends and not including a second ground point 352 (for example, Figure 13 the second antenna 302 shown), as Figure 20 shown in (c) of

[0507] It should be understood that for the sake of brevity in the discussion, in the Figure 20 shown electronic device 100, only taking the first antenna 301 as Figures 12 to 15 any one of the first antennas shown in Figures 12 to 15 and the second antenna 302 as

[0508] For the sake of brevity in the discussion, Figures 12 to 15 the first antenna 301 and the second antenna 302 shown in Figure 20The similar parts of the first antenna 301 and the second antenna 302 shown are not described one by one. For example, the similar parts include: the position and structure of the first radiator 310; the resonance generated by the first radiator 310; the position and structure of the second radiator 320; the resonance generated by the second radiator 320; the position of the first feeding point 312; the position of the second feeding point 322; the relationship between the first frequency band and the second frequency band; the equivalent inductance or equivalent capacitance value of the corresponding components when the first radiator 310 and the second radiator 320 are metamaterial structures; the position of the connection point on the radiator; and so on.

[0509] Figure 21 and Figure 22 is Figure 20 the simulation results of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) of. Among them, Figure 21 is Figure 20 the simulation results of the S parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) of. Figure 22 is Figure 20 the simulation results of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) of.

[0510] As Figure 21 shown, the first antenna (S11) can generate resonance near 2.15 GHz, and generating resonance near 2.15 GHz can correspond to the first resonance in the above embodiments.

[0511] The second antenna (S22) can generate resonance near 2.1 GHz and near 2.3 GHz. Generating resonance near 2.1 GHz can correspond to the fourth resonance in the above embodiments, and generating resonance near 2.3 GHz can correspond to the third resonance in the above embodiments. The center frequency of the second frequency band is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance. In the second frequency band, the second antenna generates radiation by the line CM mode and the line DM mode.

[0512] In the second frequency band (for example, 2170 MHz - 2200 MHz), the isolation degree (S12 / S21) between the first antenna and the second antenna is greater than 15 dB, and there is good isolation between the first antenna and the second antenna.

[0513] It should be understood that in the illustration of the simulation results shown in Figure 21 , the S parameters at the same frequency point (2.2 GHz) are shown, and this frequency point is located in the second frequency band (for example, 2170 MHz - 2200 MHz). In the actual simulation and debugging results, the depth in the S parameters may be different, and generally it is considered that a depth above 3 dB can provide communication functions.

[0514] As Figure 22 shown, when only the first antenna in the electronic device is working, in the second frequency band (e.g., 2170 MHz - 2200 MHz), the radiation efficiency of the first antenna is about -1.89 dB.

[0515] When only the second antenna in the electronic device is working, in the second frequency band (e.g., 2170 MHz - 2200 MHz), the radiation efficiency of the second antenna is about -2.8 dB.

[0516] When the first antenna and the second antenna in the electronic device are working simultaneously, in the second frequency band (e.g., 2170 MHz - 2200 MHz), the radiation efficiency of the first antenna drops by about 0.1 dB, and the radiation efficiency of the second antenna drops by about 0.2 dB.

[0517] It should be understood that in the Figure 22 illustrations of the simulation results shown, the radiation efficiency at the same frequency point (2.2 GHz) is shown, and this frequency point is located in the second frequency band (e.g., 2170 MHz - 2200 MHz). In the actual simulation and debugging results, the radiation efficiency in the radiation efficiency curve may be different. Generally, it is considered that a radiation efficiency greater than -8 dB can provide communication functions.

[0518] Figure 23 and Figure 24 are Figure 20 the radiation patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) of Figure 23 is Figure 20 the first radiation pattern generated by the first antenna 301 in the electronic device 100 shown in (a) of Figure 24 is Figure 2 the second radiation pattern generated by the second antenna 302 in the electronic device 100 shown in (a)0 of

[0519] As Figure 23 shown, due to Figure 20 in the electronic device 100 shown, the size of the ground plane is large. Affected by the current traction generated on the ground plane, the maximum radiation direction of the first radiation pattern generated by the first antenna faces the top direction of the electronic device (e.g., the z direction) and deflects towards the housing side without the first antenna (towards the second housing side).

[0520] As Figure 24 shown, the maximum radiation direction of the second radiation pattern generated by the second antenna faces the top direction of the electronic device (e.g., the z direction), and there is good radiation on both sides of the top direction.

[0521] It should be understood that the angle between the maximum radiation direction of the first radiation pattern generated by the first antenna and the maximum radiation direction of the second radiation pattern generated by the second antenna is relatively large. The electronic device can switch the first antenna or the second antenna (or, the first antenna and the second antenna work simultaneously) so that the communication satellite is always in the area where the electronic device has good radiation characteristics.

[0522] Figure 25 It is a schematic diagram of another electronic device 100 provided by an embodiment of the present application.

[0523] As Figure 25 shown, the second radiator 320 includes a second grounding point 352, and the second grounding point 352 is coupled to the floor 300. The second radiator 320 is attached to the rear cover 21 of the electronic device 100.

[0524] It should be understood that the second radiator 320 being attached to the rear cover 21 of the electronic device 100 can be understood as the second radiator 320 being located on the surface of the rear cover 21, or being disposed on the surface of the rear cover 21 through other structural members. Or, the second radiator 320 being attached to the rear cover 21 of the electronic device 100 can also be understood as, in the electronic device 100, the second radiator 320 being disposed adjacent to the rear cover 21. Among them, "adjacent" can be understood as, for example, the distance between the second radiator 320 and the rear cover 21 is within 5 mm, or the distance between the second radiator and the rear cover 21 is within 3 mm. In one embodiment, the second radiator 320 can be located on one side of the plane where the rear cover 21 is located.

[0525] In one embodiment, the second radiator 320 can be located inside the rear cover 21 (close to the PCB 17 side), as Figure 26 shown. In one embodiment, the second radiator 320 can be located between the rear cover 21 and the PCB 17. In one embodiment, the electronic device 100 can further include a bracket 251, and the second radiator 320 is located on the surface of the bracket 251. In one embodiment, a shielding cover 15 can be provided between the bracket 251 and the PCB 17. In one embodiment, electronic components can be provided inside the shielding cover 15 to avoid mutual interference between the electronic components and the second radiator 320.

[0526] It should be understood that when the second radiator 320 is located inside the electronic device 100, since the second radiator 320 is not located on the appearance surface of the electronic device 100, therefore, there is a relatively flexible layout method.

[0527] In one embodiment, the second radiator 320 can be located outside the rear cover 21 (far from the PCB 17 side), as Figure 27As shown. In one embodiment, the second radiator 320 may be a decoration piece (deco) of the camera module 252 of the electronic device 100. The decoration piece may be located on the outer surface of the camera module 252 and surround the camera module 252.

[0528] It should be understood that when the second radiator 320 is disposed on the outer side of the electronic device 100, the radiation environment of the second antenna 302 is better (for example, the clearance is larger and the distance from the electronic components disposed on the PCB 17 is farther), and the second antenna 302 has better radiation characteristics (for example, radiation efficiency).

[0529] In one embodiment, the distance (for example, the maximum distance) between the first radiator 310 and the second radiator 320 along the extension direction of the second side 132 (for example, the z direction) is less than or equal to one half of the length of the second side 132.

[0530] It should be understood that the first radiator 310 and / or the second radiator 320 may be located in the upper half (the area near the top) of the electronic device 100, which is more conducive to the radiation generated by the first antenna 301 and / or the second antenna 302 in the top direction, so that the electronic device 100 has good communication quality with the communication satellite.

[0531] It should be understood, Figure 25 the electronic device 100 shown and Figures 11 to 15 and Figure 20 the difference between the electronic device 100 shown and that of the electronic device 100 is only in the structure and position of the second radiator 320. In the above embodiment, the second radiator 320 includes the conductor part of the first frame 210 between the third position 203 and the fourth position 204, and the third position 203 and the fourth position 204 are located on the second side 132. While in Figure 25 the electronic device 100 shown, the second radiator 320 is a conductor attached to one side of the rear cover 21. Figure 25 In the electronic device 100 shown, the first antenna 301 may be Figures 11 to 15 any one of the first antennas 301 in the electronic device 100 shown. For the sake of simplicity of discussion, in the embodiments of the present application, only the first antenna 301 as Figure 14 the first antenna 301 shown in is described, and details are not described one by one.

[0532] Since the first radiator 310 is located at the top edge of the electronic device 100 and the second radiator 320 is located at the side edge of the electronic device 100. Therefore, the first antenna 301 can generate better radiation in the top direction and has better radiation characteristics. The second antenna 302 can be used to improve the radiation of the electronic device 100 in the upper hemisphere region. For example, the second antenna 302 can be used to enhance the radiation of the electronic device 100 in the top direction towards the side of the second radiator 320, and the electronic device 100 can have good communication characteristics within a larger angular range with respect to the top direction.

[0533] Among them, the upper hemisphere region can be understood as the region within an angle less than or equal to 90° with respect to the top direction. In the coordinate system, it can be understood as the region where the xoy plane faces the positive z direction.

[0534] In one embodiment, the second radiator 320 can be in any shape. In one embodiment, the second radiator 320 can be in a ring shape, as Figure 25 shown. For example, the second radiator 320 can be a decorative piece of the camera module 252 of the electronic device 100. In one embodiment, the second radiator 320 can be in a sheet shape, as Figure 28 shown.

[0535] It should be understood that the second radiator 320 can be in a strip shape (for example, the ratio of the length to the width is greater than or equal to 3), circular, trapezoidal, triangular, etc. The embodiments of the present application do not limit the shape of the second radiator 320, which can be determined according to actual production or design and will not be elaborated one by one.

[0536] In one embodiment, the second radiator 320 can form a structure similar to a patch antenna.

[0537] It should be understood that a patch antenna can be understood as a radiator having a certain width (for example, the ratio of the length to the width of the radiator is less than or equal to 10), and the radiator is disposed face to face with the floor (for example, the plane where the radiator is located and the plane where the floor is located are approximately parallel).

[0538] In one embodiment, the second radiator 320 can be used to generate a third resonance and a fourth resonance. The resonance point frequency of the third resonance is higher than the resonance point frequency of the fourth resonance, and the ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance is less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band (or the second frequency band) is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance.

[0539] In one embodiment, the second radiator 320 further includes a third grounding point 353, and the second radiator 320 is coupled to the floor 300 at the third grounding point 353.

[0540] In one embodiment, the second radiator 320 includes a first center line, and the second feeding point 322 and the center (e.g., geometric center) of the second radiator 320 are located on the first center line. The first center line divides the second radiator 320 into a first part and a second part. The second grounding point 352 is located in the first part, and the third grounding point 353 is located in the second part. It should be understood that when the second radiator 320 is in a circular ring shape or a circular shape, the center can be understood as the center of the circle; when the second radiator 320 is in a quadrilateral shape, the center can be understood as the intersection point of the diagonals; when the second radiator 320 is in other irregular shapes, the center can be understood as the center of gravity.

[0541] It should be understood that the fourth resonance can be generated by the CM mode of the patch antenna, and the third resonance can be generated by the DM mode of the patch antenna.

[0542] In the above embodiment, the line CM mode or the line DM mode can be understood as that the line antenna mainly generates radiation by current. And the CM mode of the patch antenna or the DM mode of the patch antenna can be understood as that the patch antenna mainly generates radiation by magnetic current (e.g., the magnetic field between the radiator and the ground plane).

[0543] As Figure 29 shown in (a) of [], in the CM mode of the patch antenna, the currents on the second radiator 320 are reversed on both sides of the virtual ground line (the second grounding point 352 and the third grounding point 353 are located on the virtual ground line) (when the second radiator 320 only includes one grounding point, it can be understood as the sides close to the second feeding point 322 and far from the second feeding point 322 of the grounding point).

[0544] As Figure 29 shown in (b) of [], when the second radiator is in a ring shape, in the CM mode, the currents on the second radiator 320 on both sides of the second grounding point 352 are reversed, the currents on the second radiator 320 on both sides of the third grounding point 353 are reversed, and the currents on the second radiator 320 between the second grounding point 352 and the third grounding point 353 are reversed.

[0545] As Figure 29 shown in (c) of [], in the CM mode of the patch antenna, the electric fields between the second radiator 320 and the ground plane 300 are in the same direction on both sides of the virtual ground line.

[0546] As Figure 29As shown in (d), in the CM mode of the patch antenna, the radiation generated by the second antenna has two relatively strong regions. The two relatively strong radiation regions of the second antenna are respectively biased towards the top direction of the electronic device 100 (the direction from the bottom edge to the top edge, for example, the positive direction of the z-axis) and the bottom direction of the electronic device 100 (the direction from the top edge to the bottom edge, for example, the negative direction of the z-axis). The radiation generated by the second antenna in the thickness direction of the electronic device 100 (for example, the x-axis) is relatively weak (has a null in the radiation pattern, for example, the region where the gain is relatively small, such as 2%).

[0547] In the CM mode of the patch antenna, the electric fields between the second radiator 320 and the ground plane 300 are in the same direction on both sides of the virtual ground wire, but there is partial reverse in the far field of the second radiator 320 (for example, it can be understood that the circumferential electric field shown by the curved arrow is partially reverse), as Figure 29 shown in (e). Therefore, it is possible to set the electric field of the first relatively strong radiation region in the radiation pattern generated by the second antenna to be biased towards the top direction of the electronic device 29 (the direction from the bottom edge to the top edge, for example, the positive direction of the z-axis) and the electric field of the second relatively strong radiation region to be biased towards the bottom direction of the electronic device 29 (the direction from the top edge to the bottom edge, for example, the negative direction of the z-axis), where there are at least partially reverse electric field components in the far fields of the first and second relatively strong radiation regions (for example, there are reverse electric field components in the z-axis direction).

[0548] As Figure 30 shown in (a), in the DM mode of the patch antenna, the currents on the second radiator 320 are in the same direction on both sides of the virtual ground wire.

[0549] As Figure 30 shown in (b), when the second radiator is annular, in the DM mode, the currents on the second radiator 320 on both sides of the second grounding point 352 are in the same direction, the currents on the second radiator 320 on both sides of the third grounding point 353 are in the same direction, and the currents on the second radiator 320 between the second grounding point 352 and the third grounding point 353 are reverse.

[0550] As Figure 30 shown in (c), in the DM mode of the patch antenna, the electric fields between the second radiator 320 and the ground plane 300 are in the reverse direction on both sides of the virtual ground wire.

[0551] As Figure 30As shown in (d), in the DM mode of the patch antenna, the radiation generated by the second antenna is stronger in the thickness direction (e.g., the x direction) of the electronic device 100. The radiation generated by the second antenna is weaker in the top direction of the electronic device 100 (the direction from the bottom edge to the top edge, e.g., the positive direction of the z direction) and the bottom direction of the electronic device 100 (the direction from the top edge to the bottom edge, e.g., the negative direction of the z direction) (having null points on the radiation pattern, e.g., the region where the gain is relatively small at 2%).

[0552] In the DM mode of the patch antenna, the electric field between the second radiator 320 and the floor 300 is reversed on both sides of the virtual ground wire, but is in the same direction in the far field of the second radiator 320 (e.g., it can be understood that the circumferential electric field shown by the curved arrow is basically in the same direction), as Figure 30 shown in (e). Therefore, the radiation pattern generated by the second antenna has the electric field in the same direction in the far field.

[0553] It should be understood that when the second antenna 302 operates in the CM mode of the patch antenna, the maximum radiation direction is biased towards the top direction (e.g., the positive direction of the z direction) and the bottom direction (e.g., the positive direction of the z direction). When the second antenna 302 operates in the DM mode of the patch antenna, the maximum radiation direction is biased towards the thickness direction (e.g., the x direction). In one embodiment, the center frequency of the first frequency band (or the second frequency band) is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance. In the first frequency band, the second antenna 302 generates radiation jointly by the CM mode and the DM mode of the patch antenna.

[0554] Since there are at least partially reversed electric field components in the electric fields of the radiation patterns generated by the CM mode of the patch antenna in two stronger radiation regions, and the electric fields of the radiation patterns generated by the DM mode of the patch antenna are in the same direction in the stronger radiation regions, therefore, in the radiation pattern jointly generated by the CM mode and the DM mode of the patch antenna, the radiation pattern generated by the DM mode of the patch antenna can enhance one of the two stronger radiation regions generated by the CM mode of the patch antenna and weaken the other.

[0555] The second antenna 302 generating radiation jointly by the CM mode and the DM mode of the patch antenna can enhance the radiation in the top direction (e.g., the positive direction of the z direction) of the radiation pattern generated by the second antenna 302 and weaken the radiation in the bottom direction (e.g., the positive direction of the z direction), so that the second antenna 302 can have better radiation characteristics in the top direction, enabling the electronic device 100 to have better communication performance.

[0556] In one embodiment, when the second radiator 320 is annular, the difference in length of the second radiator 320 on both sides of the virtual ground wire (the virtual ground wire is the connection line between the second ground point 352 and the third ground point 353) is within 20%.

[0557] It should be understood that as the symmetry increases, the radiation characteristics of the second antenna 302 are better.

[0558] In one embodiment, the ratio of the resonant point frequency of the third resonance to the resonant point frequency of the fourth resonance is less than or equal to 1.2. In one embodiment, the frequency difference between the resonant point frequency of the fourth resonance and the resonant point frequency of the third resonance is less than or equal to 300 MHz.

[0559] It should be understood that when the resonant points of the third resonance and the fourth resonance are close to each other, the second antenna 302 has better radiation characteristics in the first frequency band (or the second frequency band) (for example, the proportion facing the top in the radiation pattern increases).

[0560] In one embodiment, the minimum distance between the first radiator 310 and the second radiator 320 is less than or equal to 20 mm. In one embodiment, the distance between the first radiator 310 and the second radiator 320 is less than or equal to 10 mm.

[0561] In one embodiment, the distance between the first feeding point 312 and the second feeding point 322 is less than or equal to 20 mm. In one embodiment, the distance between the first feeding point 312 and the second feeding point 322 is less than or equal to 10 mm.

[0562] It should be understood that when both the first radiator and the second radiator are fed in an electrically connected manner, the distance between the first feeding point 312 and the second feeding point 322 can be understood as the distance between the center of the area where the first metal piece for feeding the first antenna 301 contacts the first radiator 310 and the center of the area where the second metal piece for feeding the second antenna 302 contacts the second radiator 320.

[0563] When both the first radiator and the second radiator are fed in an indirectly coupled manner, the distance between the first feeding point 312 and the second feeding point 322 can be understood as the distance between the center of the projection (along the direction perpendicular to the extension direction of the first radiator 310) of the end of the first metal piece for feeding the first antenna 301 on the first radiator 310 and the center of the projection (along the thickness direction of the electronic device 100) of the end of the second metal piece for feeding the second antenna 302 on the second radiator 320.

[0564] When the first radiator 310 and the second radiator 320 are fed by electrical connection and indirect coupling respectively, the corresponding understanding can be made with reference to the above embodiments.

[0565] When the distance between the first feeding point 312 and the second feeding point 322 is relatively short, the transmission line distance between the radio frequency channels (for example, the first feeding circuit 311 and the second feeding circuit 321) in the radio frequency chip and the corresponding feeding point (for example, the first feeding point 312 or the second feeding point 322) is short, and the loss of the radio frequency signal output by the radio frequency channel on this transmission path is small, which is beneficial to improving the radiation characteristics (such as gain) of the antenna (the first antenna 301 or the second antenna 302).

[0566] In one embodiment, the second antenna 302 may further include a fourth element 334, as Figure 31 shown. The second radiator 320 further includes a seventh connection point 347. The fourth element 334 is coupled between the seventh connection point 347 and the ground plane 300.

[0567] It should be understood that, in one embodiment, the fourth element 334 coupled between the ground plane 300 and the seventh connection point 347 can be used to switch the radiation characteristics (such as the maximum radiation direction) of the second antenna 302 in the first frequency band (or the second frequency band). The fourth element 334 can adjust the frequency difference between the resonance point of the third resonance and the resonance point of the fourth resonance. Thus, the center frequency of the first frequency band (or the second frequency band) is relatively close to the resonance point of the third resonance or the resonance point of the fourth resonance, realizing the adjustment of the radiation characteristics (such as the maximum radiation direction) of the second antenna 302 in the first frequency band (or the second frequency band). The fourth element 334 coupled between the ground plane 300 and the seventh connection point 347 can increase the flexibility of the adjustment of the second antenna 302.

[0568] In one embodiment, the angle formed by the seventh connection point 347 and the second feeding point 322 is greater than or equal to 45°. In one embodiment, the angle formed by the seventh connection point 347 and the second feeding point 322 is greater than or equal to 90°. In one embodiment, the angle formed by the seventh connection point 347 and the second feeding point 322 is greater than or equal to 135°.

[0569] It should be understood that the angle formed by the seventh connection point 347 and the second feeding point 322 can be understood as the smaller angle among the angles formed by the seventh connection point 347 and the second feeding point 322 relative to the center of the second radiator 320, or it can also be understood as the angle less than or equal to 180° among the angles formed by the seventh connection point 347 and the second feeding point 322 relative to the center of the second radiator 320. As the angle formed by the seventh connection point 347 and the second feeding point 322 increases, the adjustable range of the fourth element 334 further increases.

[0570] In one embodiment, the fourth element 334 can be a capacitor or an element equivalent to a capacitor. In one embodiment, the equivalent capacitance value of the fourth element 334 can be less than or equal to 1 pF.

[0571] In one embodiment, the fourth element 334 can be an inductor or an element equivalent to an inductor.

[0572] The second antenna 302 may further include a switch 340 and a plurality of elements, such as Figure 32 shown. In one embodiment, the second antenna 302 may include a fourth element 334 and a fifth element 335.

[0573] For the sake of simplicity of discussion, in the Figure 32 illustrated electronic device 100, only the switch 340 being a single-pole four-throw (DPFT) is taken as an example for illustration. In actual production or design, replacements can be made. For example, the switch 340 can be a double-pole X-throw (DPXT), or, an X-pole X-throw (XPXT), or formed by a combination of multiple single-pole single-throw (SPST). The embodiments of the present application do not limit this, and the switches described in the embodiments of the present application can be understood accordingly.

[0574] Among them, the switch 340 is coupled between the seventh connection point 347 and the ground plane 300. A plurality of elements (for example, the fourth element 334 and the fifth element 335) can be coupled between the switch 340 and the ground plane 300 or between the switch 340 and the seventh connection point 347.

[0575] In one embodiment, the element coupled between the ground plane 300 and the seventh connection point 347 can be used to switch the radiation characteristics (for example, the maximum radiation direction) of the second antenna 302 in the first frequency band (or the second frequency band).

[0576] It should be understood that the Figure 31 illustrated electronic device 100 may include only one element (for example, the fourth element 334). While in the Figure 32 illustrated electronic device 100, a plurality of elements (for example, the fourth element 334 and the fifth element 335) are included. The equivalent capacitance value or the equivalent inductance value of the element coupled between the seventh connection point 347 and the ground plane 300 can be switched through the switch 340, or the boundary conditions of the seventh connection point 347 can be switched through the switch 340. For example, the seventh connection point 347 is disconnected from the ground plane 300, or, the seventh connection point 347 is directly electrically connected to the ground plane 300 (no element is provided), and the frequency difference between the resonance point of the third resonance and the resonance point of the fourth resonance can be adjusted.

[0577] By adjusting the frequency difference between the resonance points of the third resonance and the fourth resonance, the center frequency of the first frequency band can be made relatively close to the resonance point of the third resonance or the resonance point of the fourth resonance. For example, the fourth element 334 and the second radiator 320 are used to generate the third resonance 1 and the fourth resonance 1. The fifth element 335 and the second radiator 320 are used to generate the third resonance 2 and the fourth resonance 2. The first frequency difference and the second frequency difference are different. The first frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the third resonance 1, and the second frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the third resonance 2. Alternatively, the third frequency difference and the fourth frequency difference are different. The third frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the fourth resonance 1, and the fourth frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the fourth resonance 2.

[0578] Since the center frequency of the first frequency band can be relatively close to the resonance point of the third resonance or the resonance point of the fourth resonance, the radiation characteristics (e.g., the maximum radiation direction) of the second antenna 302 in the first frequency band (or the second frequency band) can be adjusted, thereby realizing the switching of the radiation characteristics (e.g., the maximum radiation direction) of the second antenna 302 in the first frequency band.

[0579] In one embodiment, the element coupled between the ground plane 300 and the seventh connection point 347 can be used to switch the operating frequency band of the second antenna 302.

[0580] It should be understood that in Figure 31 the illustrated electronic device 100 may include only one element (e.g., the fourth element 334). While in Figure 32 the illustrated electronic device 100, multiple elements are included (e.g., the fourth element 334 and the fifth element 335). The equivalent capacitance value or the equivalent inductance value of the element coupled between the seventh connection point 347 and the ground plane 300 can be switched through the switch 340, or the boundary condition of the seventh connection point 347 can be switched through the switch 340. For example, the seventh connection point 347 is disconnected from the ground plane 300, or the seventh connection point 347 is directly electrically connected to the ground plane 300 (without setting an element), and the resonance point frequencies of the third resonance and the fourth resonance can be adjusted. For example, the fourth element 334 and the second radiator 320 are used to generate the third resonance 1 and the fourth resonance 1. The fifth element 335 and the second radiator 320 are used to generate the third resonance 2 and the fourth resonance 2. The center frequency of the first frequency band is less than the resonance point frequency of the fourth resonance 1 and greater than the resonance point frequency of the third resonance 1. The center frequency of the second frequency band is less than the resonance point frequency of the fourth resonance 2 and greater than the resonance point frequency of the third resonance 2. The operating frequency band of the second antenna 302 can be switched by switching the fourth element 334 and the fifth element 335.

[0581] In one embodiment, when the electronic device 100 is not performing satellite communication, the switch 340 can also be used to switch the operating frequency band of the second antenna 302 to achieve antenna multiplexing. For example, the second antenna can also be used as a cellular antenna, a WiFi antenna, etc., which will not be elaborated one by one.

[0582] It should be understood that in [[ID and ​ and ​ In the electronic device 100 shown, the first antenna 301 located at the top is the same as the first antenna 301 shown in ​ and will not be elaborated. The second antenna 302 attached to the back cover 21 of the electronic device 100 can be simplified to a patch antenna with an intermediate ground, and its overall electrical size is half a wavelength. The upper end of the second radiator 320 (the side close to the first radiator 310) is fed, and the lower end of the second radiator 320 is tuned by connecting a capacitor or an inductor. By adjusting the device that generates the resonance of the CM mode of the patch antenna, the resonance generated by the CM mode of the patch antenna is tuned to be before the resonance generated by the DM mode, so as to achieve a current combination of the CM mode of the patch antenna and the DM mode of the patch antenna in the operating frequency band of the second antenna 302, so that the current distribution on the second radiator 320 tends to the upper hemisphere region (the region close to the first radiator 310), and its radiation pattern is also the superposition of the radiation patterns generated by the CM mode of the patch antenna and the DM mode of the patch antenna, which is a radiation pattern mainly radiating in the direction of the top. Therefore, by superimposing the radiation patterns of the first antenna 301 located at the top and the second antenna 302, a better combined gain can be obtained.

[0583] Moreover, since the second radiator 320 of the second antenna 302 does not include the conductive part of the first frame, the system cost paid due to the compatibility design when the conductive part of the first frame is multiplexed as a satellite antenna and a cellular antenna can be reduced.

[0584] For the sake of brevity in discussion, ​ the similar parts of the first antenna 301 and the second antenna 302 shown in ​ and the first antenna 301 and the second antenna 302 shown in

[0585] ​ and ​ will not be elaborated one by one. For example, the similar parts include: the position and structure of the first radiator 310; the resonance generated by the first radiator 310; the position of the first feeding point 312; the relationship between the first frequency band and the second frequency band; the equivalent inductance or equivalent capacitance value of the corresponding components when the first radiator 310 is a metamaterial structure; the position of the connection point on the radiator; and so on. ​ In the electronic device 100 shown, ​ is​ The simulation results of S parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 are shown. ​ yes ​ The simulation results of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 are shown.

[0586] like ​ As shown, the first antenna (S11) can resonate at around 1.95 GHz and around 2.2 GHz. The resonance at around 1.95 GHz may correspond to the second resonance in the above embodiment, and the resonance at around 2.2 GHz may correspond to the first resonance in the above embodiment.

[0587] The second antenna (S22) can resonate near 1.95 GHz and near 2.25 GHz. The resonance near 1.95 GHz can correspond to the fourth resonance in the above embodiment, and the resonance near 2.25 GHz can correspond to the third resonance in the above embodiment. The center frequency of the second frequency band is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance. In the second frequency band, the second antenna radiates from the CM mode and the DM mode of the patch antenna.

[0588] In the second frequency band (eg, 2170 MHz-2200 MHz), the isolation (S12 / S21) between the first antenna and the second antenna is greater than 13 dB, and there is good isolation between the first antenna and the second antenna.

[0589] like ​ As shown, when the first antenna and the second antenna in the electronic device work simultaneously, in the second frequency band (eg, 2170 MHz-2200 MHz), the radiation efficiency of the first antenna is approximately -2.2 dB, and the radiation efficiency of the second antenna is approximately -4.7 dB.

[0590] It should be understood that ​ The simulation result diagram shown shows the radiation efficiency at the same frequency point (2.2 GHz), which is located in the second frequency band (e.g., 2170 MHz-2200 MHz). In actual simulation and debugging results, the radiation efficiency in the radiation efficiency curve may be different. It is generally believed that communication functions can be provided if it is greater than -8 dB.

[0591] ​ and ​ yes ​ The directional patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 are shown. ​ yes ​ The first antenna 301 in the electronic device 100 is shown to generate a first radiation pattern. ​ yes​ The second radiation pattern generated by the second antenna 302 in the electronic device 100 shown.

[0592] As ​ shown, the maximum radiation direction of the first radiation pattern generated by the first antenna faces the top direction (e.g., the z direction) of the electronic device, and the first antenna has good radiation characteristics in the vicinity of the top direction.

[0593] As ​ shown, since the center frequency of the second frequency band is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance, in the first frequency band, the second antenna radiates jointly by the CM mode and the DM mode of the patch antenna, and the radiation of the radiation pattern generated by the second antenna in the top direction (e.g., the z direction) is enhanced, and it can communicate with the communication satellite better.

[0598] Among them, the coincidence of the second position 202 and the third position 203 can be understood as the second position 202 and the third position 203 being the same, and the second position 202 and the third position 203 being the same position. For the sake of simplicity of discussion, the coincidence described in the embodiments of the present application can be understood accordingly, and will not be elaborated one by one.

The first radiator 310 includes a first feeding point 312, and the first feeding circuit 311 is coupled to the first feeding point 312.

[0604] The second radiator 320 of the second antenna 302 includes the conductive part of the first border 210 between the third position 203 and the fourth position 204.

The second radiator 320 includes a second feeding point 322, and the second feeding circuit 321 is coupled to the second feeding point 322.

The second antenna 302 can be used to improve the radiation of the electronic device 100 in the upper hemisphere region. For example, the second antenna 302 can be used to enhance the radiation of the electronic device 100 on the side of the second radiator 320 in the top direction, and the electronic device 100 can have good communication characteristics within a larger angular range with respect to the top direction.
