Description

[0001] This application claims priority to Chinese Patent Application No. 202311840097.2, filed on December 27, 2023, entitled "An Electronic Device", and Chinese Patent Application No. 202410544898.2, filed on April 28, 2024, entitled "An Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of wireless communication, and more particularly to an electronic device. Background Technology

[0003] Currently, existing terminal electronic devices utilize the frame as an antenna radiator. For example, in satellite communication systems, the frame radiator is mainly used to form a linearly polarized antenna. When a user conducts satellite communication, the area of ​​the antenna with good radiation characteristics (e.g., the antenna gain in this area is greater than or equal to AdBic, where A is the minimum gain value that meets the communication requirements of the satellite communication system) needs to be pointed towards the satellite to achieve satellite connection (establish a communication link with the satellite).

[0004] However, during satellite communication, the relative position of the electronic device and the satellite changes. For example, a low-Earth orbit satellite may move, potentially moving beyond the area where the antenna has good radiation characteristics. In such cases, the user needs to change their grip or move the device to keep the satellite within the area where the antenna has good radiation characteristics to maintain alignment or establish a connection with a new satellite. Otherwise, poor communication quality or even dropped calls will occur, significantly impacting the user's communication experience. Summary of the Invention

[0005] This application provides an electronic device including a first antenna and a second antenna. The operating frequency bands of the first antenna and the second antenna include satellite communication frequency bands. The first antenna and the second antenna can generate different maximum radiation directions. The electronic device can perform satellite communication by switching between the first antenna and the second antenna, or by simultaneously using both antennas, which can improve the user's experience when performing satellite communication.

[0006] In a first aspect, an electronic device is provided, comprising: a floor; a first frame, the first frame including a first position, a second position, a third position, and a fourth position sequentially disposed therefrom, the first frame being coupled to or having an insulating gap with the floor at the first position, the first frame being coupled to or having an insulating gap with the floor at the second position, the first frame being coupled to or having an insulating gap with the floor at the third position, and the first frame being coupled to or having an insulating gap with the floor 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, ... The first antenna comprises at least a portion of a first radiator spaced apart from the floor, and a first feed circuit, the first radiator including a first feed point, the first feed circuit coupled to the first feed point, the first feed circuit being used for radio frequency signals in the satellite communication band; the second antenna comprises: a second radiator, the second radiator including a conductive portion of the first frame between the third and fourth positions, at least a portion of the second radiator spaced apart from the floor, and a second feed circuit, the second radiator including a second feed point, the second feed circuit coupled to the second feed point, the second feed circuit being used 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 this 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, 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 performance 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 second radiator, and the electronic device can have good communication characteristics over a larger angle range with respect to the top direction. The upper hemisphere region can be understood as the region within the range where the angle with respect to the top direction is less than or equal to 90°. In the coordinate system, it can be understood as the region in the positive direction of the xoy plane towards the z direction.

[0008] In conjunction with the first aspect, in some implementations 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 an embodiment of this application, the resonance generated by the first radiator is produced by a linear DM mode. The radiation pattern generated by the linear DM mode does not have a strong current flowing to the ground; therefore, the current exciting the ground is small, and the ground's effect on the radiation pattern generated by the linear DM mode is similar to that of a reflector. Thus, the radiation pattern generated by the linear DM mode is mainly oriented towards the top of the electronic device (the direction in which the first radiator is away from the ground, e.g., the z-direction). However, the radiation pattern generated by the linear CM mode has a stronger current flowing to the ground, resulting in a larger current exciting the ground. Since the ground has a greater influence on the radiation pattern generated by the antenna, the radiation pattern generated by the linear CM mode is not mainly oriented towards the top of the electronic device (the direction in which the first radiator 310 is away from the ground, e.g., the z-direction).

[0010] Furthermore, in satellite communication bands, the efficiency (e.g., radiation efficiency) of antennas resonating using the line DM mode can meet the requirements of satellite communication. For example, when the first radiator extends in a straight line, both conductor loss and dielectric loss are relatively small under the action of the same current, resulting in higher efficiency (e.g., radiation efficiency) for the first antenna. However, in the line CM mode, due to the reverse current on the radiator, the loss is larger, leading to lower efficiency (e.g., radiation efficiency) for antennas resonating using the line CM mode.

[0011] In conjunction with the first aspect, in some implementations of the first aspect, the first antenna further includes: a first tuning circuit, the first radiator including a first connection point, the first tuning circuit coupled to the first connection point, the first connection point and the first feed point being located on both sides of a first virtual axis of the first radiator, and the lengths of the first radiators on both sides of the first virtual axis being the same.

[0012] According to an embodiment of this application, the first tuning circuit can be used to switch the resonant frequency of the first antenna, so that the operating frequency band of the first antenna includes different communication frequency bands at different times / periods.

[0013] In conjunction with the first aspect, in some implementations 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 between the first connection point and the floor through the first switch.

[0014] According to an embodiment of this application, the first switch branch and the second switch branch can be used to adjust the current distribution on the floor, thereby causing the first radiation pattern generated by the first antenna to deflect.

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

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

[0017] In conjunction 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 at the first grounding point; based on the coupling of the first connection point to the first switch branch, the first radiator is also used to generate a third resonance, and there is a first frequency difference between the resonant frequency of the first resonance and the resonant frequency of the third resonance; based on the coupling of the first connection point to the second switch branch, the first radiator is also used to generate a fourth resonance, and there is a second frequency difference between the resonant frequency of the second resonance and the resonant 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 50MHz.

[0018] According to an embodiment of this application, when the difference between the first frequency difference and the second frequency difference is within the aforementioned range, and the first connection point is coupled to the first switch branch or the second switch branch respectively, the difference between the current on the ground plane on the first side of the virtual axis and the current on the ground plane on the second side of the virtual axis is greater, thereby making the difference between the first radiation pattern and the second radiation pattern greater (e.g., the angle between the maximum radiation directions increases), which can further widen the beamwidth of the first antenna. The first antenna has a wider beamwidth, enabling the first antenna to have good communication characteristics over a wider angular range (the angle with respect to the top direction).

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

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

[0021] According to an embodiment of this application, the first feed point can be located near the second antenna. In one embodiment, the first feed circuit and the second feed circuit can be generated by different RF channels of the same RF chip. When the first feed point is close to the second feed point, the current transmission path from the RF chip to the first and second feed points is shorter, which can reduce the loss caused by line transmission and improve the radiation characteristics of the antenna.

[0022] Furthermore, since there is usually a strong current in the area near the feed point, when the first feed point can be located close to the second antenna, it is easier to enhance the current on the ground of the second side of the virtual axis, causing the maximum radiation direction of the pattern generated by the first antenna to deflect away from the second antenna, making the difference between the patterns of the first antenna and the second antenna greater, thereby enabling the electronic device to have good communication characteristics over a wider range of angles (angles with the top direction).

[0023] In conjunction 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 at the first grounding point; wherein the first radiator is used to generate a first resonance and a second resonance, and the resonant frequency of the second resonance is lower than the resonant frequency of the first resonance; wherein the ratio between the resonant frequency of the first resonance and the resonant frequency of the second resonance is less than or equal to 1.3; the center frequency of the satellite communication band is greater than the resonant frequency of the second resonance and less than the resonant frequency of the first resonance.

[0024] According to an embodiment of this application, in a first frequency band (or a second frequency band), the first antenna can operate in a hybrid mode of line CM mode and line DM mode, and the radiation is generated by both line CM mode and line DM mode. The first antenna simultaneously has some radiation characteristics of line CM mode and some radiation characteristics of line DM mode.

[0025] In conjunction with the first aspect, in some implementations 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 an embodiment of this application, the first grounding point can be located in a region close to the center of the first radiator to better excite the first radiator to generate line CM mode and line DM mode. Furthermore, when the first grounding point is located in a region close to the center of the first radiator, it is easier to adjust the frequency difference between the resonances generated by the line CM mode and the line DM mode, thus giving the first antenna superior radiation characteristics.

[0027] In conjunction 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 ground at the second position, or the first frame is coupled to the ground at the first position, the first frame has a second insulating gap at the second position.

[0028] According to an embodiment of this application, the first radiator has a structure with one end grounded and the other end open. Furthermore, the third insulating gap in the first radiator can be considered as an equivalent capacitance (e.g., distributed capacitance) on the first radiator, which allows the first radiator to form a metamaterial structure. The first radiator with this metamaterial structure can increase the radiation aperture, and the electric field is more dispersed after the fifth insulating gap is added. In one embodiment, the dielectric loss near the first radiator forming the metamaterial structure is reduced, thus effectively improving the radiation characteristics of the first antenna (e.g., system efficiency and radiation efficiency).

[0029] Furthermore, by coupling the first element 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 (e.g., the resonant frequency of the first resonance generated by the first radiator).

[0030] In conjunction 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.

[0032] According to an embodiment of this application, the second radiator has a structure with one end grounded and the other end open. The second radiator can be formed into a structure similar to an inverted F antenna or a left-handed antenna.

[0033] In conjunction with the first aspect, in some implementations 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, the second radiator has a sixth insulating gap between the fourth connection point and the fifth connection point, 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, the first frame is coupled to the ground at the fourth position, or the first frame is coupled to the ground at the third position, the first frame has a fifth insulating gap at the fourth position.

[0034] According to an embodiment of this application, the second radiator has a structure with one end grounded and the other end open. Furthermore, the sixth insulating gap in the second radiator can be considered as an equivalent capacitance (e.g., a distributed capacitance) disposed on the second radiator, which allows the second radiator to form a metamaterial structure.

[0035] In conjunction with the first aspect, in some implementations 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 conjunction with the first aspect, in some implementations 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 this application, the resonance generated by the second radiator is produced by a linear DM mode. The radiation pattern generated by the linear DM mode does not have a strong current flowing to the ground; therefore, the current excited on the ground is small. The ground's effect on the radiation pattern generated by the linear DM mode is similar to that of a reflector, thus the radiation pattern generated by the linear DM mode is mainly oriented towards the top of the electronic device (the direction in which the first radiator is away from the ground, e.g., the z-direction). However, the radiation pattern generated by the linear CM mode has a stronger current flowing to the ground, resulting in a larger current excited on the ground. Since the ground has a greater influence on the radiation pattern generated by the antenna, the radiation pattern generated by the linear CM mode is not mainly oriented towards the top of the electronic device (the direction in which the first radiator 310 is away from the ground, e.g., the z-direction).

[0038] In conjunction with the first aspect, in some implementations of the first aspect, the second antenna further includes: a second tuning circuit, the second radiator including a second connection point, the second tuning circuit coupled to the second connection point, the second connection point and the second feed point being located on both sides of a second virtual axis of the second radiator, and the second radiator on both sides of the second virtual axis having the same length.

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

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

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

[0042] According to the embodiments of this application, in the first frequency band (or the second frequency band), the second antenna can operate in a mixed mode of line CM mode and line DM mode, and the radiation is generated by both line CM mode and line DM mode.

[0177] The following explains the terminology that may appear in the embodiments of this application.

[0178] It should be understood that the term "and / or" used in this document is merely a description of the same field in the related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0179] The phrase "within the range" used in this application, unless otherwise specified, includes both endpoints of the range by default. For example, in the range of 1 to 5, it includes the values ​​1 and 5.

[0180] Coupling can be understood as direct coupling and / or indirect coupling. "Coupled connection" can be understood as a direct coupling connection and / or indirect coupling connection. Direct coupling can also be called "electrical connection," which is understood as physical contact and electrical conduction between components; it can also be understood as the form of connection between different components in a circuit structure through physical lines that can transmit signals, such as copper foil or wires on a printed circuit board (PCB). "Indirect coupling" can be understood as two conductors conducting electricity through a gap / non-contact method. In one embodiment, indirect coupling can also be called capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gaps between two conductive components.

[0181] Components / devices: including at least one of lumped components / devices and distributed components / devices.

[0182] Lumped components / devices: This refers to all components whose size is much smaller than the wavelength relative to the circuit's operating frequency. For signals, the characteristics of these components remain constant regardless of frequency. Lumped components / devices can include lumped capacitors, lumped inductors, etc.

[0183] Distributed elements / devices: Unlike lumped elements, when a signal passes through an element, the characteristics of each point within the element will vary depending on the signal. Therefore, the element as a whole cannot be considered a single entity with fixed characteristics, and should be called a distributed element. Distributed elements / devices can include distributed capacitance, distributed inductance, etc.

[0184] Capacitance: 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 two conductive components separated by a certain gap.

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

[0186] Radiator: In an antenna, this is the device used to receive / transmit electromagnetic wave radiation. In some cases, the term "antenna" is narrowly defined as a radiator, which converts guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via a feed line, where it is converted into electromagnetic wave energy of a specific polarization and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a specific polarization from a specific direction in space back into modulated high-frequency current energy, which is then transmitted to the receiver input via a feed line.

[0187] The radiator may include a conductor with a specific shape and size, such as a wire or sheet, and this application does not limit the specific shape. In one embodiment, the wire radiator may be simply referred to as a wire antenna. In one embodiment, the wire radiator may be implemented by a conductive frame, and may also be referred to as a frame antenna. In one embodiment, the wire radiator may be implemented by a support conductor, and may also be referred to as a support antenna. In one embodiment, the wire diameter (e.g., including thickness and width) of the wire radiator, or the radiator of the wire antenna, is much smaller than the wavelength (e.g., the wavelength of the medium) (e.g., less than 1 / 16 of the wavelength), and the length may be comparable to the wavelength (e.g., the wavelength of the medium) (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, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, in a dipole antenna, each dipole antenna typically includes two radiating stubs, each fed from the feed end of the radiating stub by a feed section. For example, an inverted-F antenna (IFA) can be considered as a monopole antenna with an added ground path. An IFA antenna has one feed point and one ground point, and is called an inverted-F antenna because its side view is inverted-F shaped. In one embodiment, the sheet radiator may include a microstrip antenna or a patch antenna, such as a planar inverted-F antenna (also known as a PIFA). In one embodiment, the sheet radiator may be implemented using a planar conductor (e.g., a conductive sheet or conductive coating). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet. In one embodiment, the sheet radiator may include a conductive coating, such as silver paste. The shape of the sheet radiator includes circular, rectangular, and annular shapes, and this 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, wherein the dielectric substrate is disposed between the radiator and the ground plane.

[0188] Radiators may also include slots or gaps formed on a conductor, for example, closed or semi-closed slots or gaps formed on a grounded conductor surface. In one embodiment, a slotted or slit radiator may be simply referred to as a slot antenna or a gap antenna. In one embodiment, the radial dimension (e.g., including width) of the slot or gap of the slot antenna / gap antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), while the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., a length of approximately 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). In one embodiment, a radiator with a closed slot or gap may be simply referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or gap (e.g., an opening added to a closed slot or gap) may be simply referred to as an open slot antenna. In some embodiments, the gap shape is elongated. In some embodiments, the length of the gap is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the length of the gap is approximately an integer multiple of a wavelength (e.g., one dielectric wavelength). In some embodiments, the slot can be fed by transmission lines connected across one or both sides, thereby exciting a radio frequency electromagnetic field on the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a conductive frame grounded at both ends, also known as a frame antenna; in this embodiment, the slot antenna or gap antenna can be viewed as including a linear radiator, the linear radiator being spaced apart from the ground and grounded at both ends, thereby forming a closed or semi-closed slot or gap. In one embodiment, the radiator of the slot antenna or gap antenna can be implemented by a support conductor grounded at both ends, also known as a support antenna.

[0189] A power supply circuit is a circuit used for receiving and / or transmitting radio frequency (RF) signals. A power supply circuit can include a transceiver and an RF front-end. In some narrower senses, "power supply circuit" refers to an RF IC (Radio Frequency Integrated Circuit), which can be considered to include both the RF front-end circuit (or RF front-end chip) and the transceiver. The power supply circuit has the function of converting radio waves (e.g., RF signals) into signals (e.g., digital signals). It is generally considered part of the RF component.

[0190] In some embodiments, the electronic device may also include a test socket (or, RF socket, or RF test socket). This test socket can be used to insert a coaxial cable to test the characteristics of the RF front-end circuitry or the radiator of the antenna. The RF front-end circuitry can be considered as the circuitry 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 an electronic device.

[0192] It should be understood that any two feed circuits in the first / second / ...Nth feed circuit of this application may include the same transceiver. For example, one transmit channel of a transceiver may serve as the first feed circuit and one receive channel may serve as the second feed circuit, or for example, the first receive channel of a transceiver may serve as the first feed circuit and the second receive channel may serve as the second feed circuit. Any two feed circuits in the first / second / ...Nth feed circuit of this application may also include the same radio frequency front-end circuit, for example, the signal may be processed by a tuning circuit or amplifier in a radio frequency front-end circuit.

[0193] It should also be understood that the two feed circuits in the first / second / ...Nth feed circuit of this application typically correspond to two RF test sockets in an electronic device.

[0194] A matching circuit is a circuit used to adjust the radiation characteristics of an antenna. In one embodiment, the matching circuit is coupled between the feed circuit and the corresponding radiator. In another embodiment, the matching circuit is coupled between the test mount and the radiator. Typically, the matching circuit is a combination of circuits coupled between the radiator and the ground plane. In one embodiment, the matching circuit may include a tuning circuit and / or components, which may be components for switching the coupling connection of the radiator. The matching circuit has impedance matching and / or frequency tuning functions. It is typically considered part of the antenna.

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

[0196] End / Point: The term "end / point" in the context of the antenna radiator's first end / second end / feed end / ground end / feed point / grounding point / connection point should not be narrowly interpreted as necessarily being a point or end physically disconnected from other radiators. It can also be considered as a point or segment on a continuous radiator. In one embodiment, "end / point" can include a connection / coupling region on the antenna radiator that couples to other conductive structures. For example, a feed end / feed point can be a connection / coupling region on the antenna radiator that couples to a feed structure or feed circuit (e.g., a region facing a part of the feed circuit). Similarly, a ground end / grounding point can be a connection / coupling region on the antenna radiator that couples to a ground structure or ground circuit (e.g., a region facing a part of the ground circuit).

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

[0198] In some embodiments, the understanding of "closed end" can also be from the perspective of current distribution. A closed end or ground end can be understood as a point of high current or low electric field on a radiator. In one embodiment, coupling electronic devices (e.g., capacitors, inductors, etc.) through a closed end can maintain the current distribution characteristics of the point of high current / low electric field. In one embodiment, opening a slit at or near the closed end (e.g., filling the slit with insulating material) can maintain the current distribution characteristics of the point of high current / low electric field.

[0199] In some embodiments, the understanding of "open terminal" can also be from the perspective of current distribution. An open terminal or a floating terminal can be understood as a point with a small current or a point with a large electric field on the radiator. In one embodiment, coupling electronic devices (e.g., capacitors, inductors, etc.) through an open terminal can maintain the current distribution characteristics of the point with a small current or a large electric field.

[0200] It should be understood that when an electronic device (e.g., capacitor, inductor, etc.) is coupled at the radiator end of a gap (which, from the perspective of the radiator's structure, is similar to the radiator at the opening of an open or floating end), the radiator end can be a point with a large current / small electric field. In this case, it should be understood that the radiator end at the gap is actually a closed end or a grounded end, etc.

[0201] The "floating radiator" mentioned in the embodiments of this application refers to a radiator that is not directly connected to the feed line / feed branch and / or ground line / ground branch, but is fed and / or grounded through indirect coupling.

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

[0203] The current in the same direction / opposite direction mentioned in the embodiments of this application should be understood as the main current on the same side of the conductor being in the same direction / opposite direction. For example, when a current distributed in the same direction is excited on a conductor that is bent or looped (e.g., the current path is also bent or looped), it should be understood that, for example, the main current excited on the conductors on both sides of a looped conductor (e.g., on the conductors on both sides of a gap) is opposite in direction, but it still falls under the definition of current distributed in the same direction in the embodiments of this application. In one embodiment, current in the same direction on a conductor can mean that the current on the conductor has no reverse point. In one embodiment, current in opposite direction on a conductor can mean that the current on the conductor has at least one reverse point. In one embodiment, current in the same direction on two conductors can mean that the current on both conductors has no reverse point and flows in the same direction. In one embodiment, current in opposite direction on two conductors can mean that the current on both conductors has no reverse point and flows in opposite directions. Current in the same direction / opposite direction 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 a frequency range where the return loss characteristic is less than -5dB. The point of strongest resonance can be called the resonant point, and the frequency corresponding to the resonant point is the center frequency. The return loss characteristic of the center frequency can be less than -10dB, -15dB, or less than -20dB. It should be understood that, unless otherwise specified, when the antenna / radiator in this application generates "first / second...resonance," the first resonance should be the fundamental mode resonance generated by the antenna / radiator, or in other words, the lowest frequency resonance generated by the antenna / radiator. It should be understood that the antenna / radiator can generate one or more antenna modes according to a specific design, and each antenna mode can correspond to a fundamental mode resonance.

[0205] Resonant frequency band: The range of resonant frequencies is the resonant frequency band. The frequency range in which the return loss characteristic of the resonant frequency point is less than -5dB can be regarded as the resonant frequency band.

[0206] Communication band / operating band: Regardless of the type of antenna, it always operates within a certain frequency range (bandwidth). For example, an antenna supporting the B40 band operates within the frequency range of 2300MHz to 2400MHz, or in other words, the antenna's operating band includes the B40 band. The frequency range that meets the specifications can be considered the antenna's operating band.

[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: can be the ratio of physical length (i.e., mechanical length or geometric length) to the wavelength of the transmitted electromagnetic wave. 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 operating wavelength, 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 band (resonant frequency from 1920MHz to 1980MHz) is 1955MHz, then the operating wavelength can be the wavelength calculated using this frequency. Not limited to the center frequency, "operating wavelength" can also refer to the wavelength corresponding to the non-center frequency of the resonant frequency or 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 × 10⁻⁶. 8 m / s. The wavelength of the radiated signal in the medium can be calculated as follows: Where ε is the relative permittivity of the medium. The wavelength in the embodiments of this application typically 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 band (resonant frequency of 1920MHz to 1980MHz) is 1955MHz, then the wavelength can be the medium wavelength calculated using this frequency. Not limited to the center frequency, the "medium wavelength" can also refer to the medium wavelength corresponding to the non-center frequency of the resonant frequency or operating frequency band. For ease of understanding, the medium wavelength mentioned in the embodiments of this application can be simply calculated using the relative permittivity of the medium filling one or more sides of the radiator.

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

[0214] Antenna radiation efficiency refers to the ratio of the power radiated into space by an antenna (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. Active power input to the antenna = antenna input power - loss power; loss power mainly includes return loss power and ohmic loss power of metals and / or dielectric loss power. Radiation efficiency is a measure of an antenna's radiation capability; metal loss and dielectric loss are both factors affecting radiation efficiency.

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

[0216] Antenna return loss: This can be understood as the ratio of the signal power reflected back to the antenna port after passing through the antenna circuit to the transmit power at the antenna port. The smaller the reflected signal, the larger the signal radiated into space through the antenna, and the higher the antenna's radiation efficiency. Conversely, the larger the reflected signal, the smaller the signal radiated into space through the antenna, and the lower the antenna's radiation efficiency.

[0217] Antenna return loss can be represented by the S11 parameter, which is one of the S-parameters. S11 represents the reflection coefficient, and this parameter characterizes the antenna's transmission efficiency. The S11 parameter is usually negative. The smaller the S11 parameter, the smaller the antenna return loss, the less energy the antenna reflects back, which means more energy actually enters the antenna, and the higher the antenna's system efficiency. Conversely, the larger the S11 parameter, the greater the antenna return loss, and the lower the antenna's system efficiency.

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

[0219] Antenna radiation pattern: also known as radiation pattern. It refers to the graph showing the relative field strength (normalized modulus) of the antenna's radiated field as a function of direction at a certain distance from the antenna (far field). It is usually represented by two mutually perpendicular planar radiation patterns passing through the direction of maximum radiation of the antenna.

[0220] Antenna radiation patterns typically have multiple radiating beams. The beam with the highest radiating intensity is called the main lobe, and the remaining beams are called side lobes. Among the side lobes, the side lobe in the opposite direction to the main lobe is also called the back lobe.

[0221] Beamwidth: refers to the angle between the antenna and the direction pointing towards the top of the electronic device (e.g., the y-direction). Within a first angle range, the gain of the antenna's radiation pattern is greater than or equal to a threshold. The first angle is the beamwidth. When the first angle is large, for example, greater than or equal to 60°, the antenna can be considered to have wide beam characteristics, and the antenna has good radiation characteristics within this angle range.

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

[0223] Antenna gain: Characterizes the degree to which an antenna concentrates the radiated input power. Generally, the narrower the main lobe and the smaller the side lobes of the antenna pattern, the higher the antenna gain.

[0224] Antenna polarization: At a given point in space, the electric field intensity E (vector) is a function of time t. As time progresses, the endpoint of the vector periodically traces a trajectory in space. If this 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 elliptical or circular, and when viewed along the propagation direction, it rotates clockwise or right-handed with time, it is called right-hand circular polarization (RHCP); if it rotates counterclockwise or left-handed with time, it is called left-hand circular polarization (LHCP).

[0225] Ground (GND): can generally refer to at least a portion of any grounding layer, ground plane, or grounding metal layer within an electronic device (such as a mobile phone), or at least a portion of any combination of the aforementioned grounding layers, ground planes, or grounding components. "Ground" can be used for grounding components within an electronic device, or in other words, can be used as a reference ground for components within an electronic device. Typically, large areas of metal (e.g., metal layers) within an electronic device can serve as "ground." In one embodiment, "ground" can include any one or more of the following: a grounding layer of the electronic device's circuit board, a ground plane formed by the electronic device's frame, a grounding metal layer formed by a thin metal film beneath the screen, a conductive grounding layer of a battery, a metal hinge of a foldable electronic device, a metal back cover of the electronic device (e.g., when at least a portion of the back cover is metal), and conductive or metal components electrically connected to the aforementioned grounding layer / ground plane / metal layer. In one embodiment, the circuit board may be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12-to-14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or components separated and electrically insulated by dielectric 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, the trace layer and the ground layer being electrically connected via vias. In one embodiment, components such as displays, touchscreens, input buttons, transmitters, processors, memory, batteries, charging circuits, and system-on-chip (SoC) devices may be mounted on or connected to the circuit board; or electrically connected to the trace layers and / or ground layers in the circuit board. For example, a radio frequency source is disposed on a trace layer.

[0226] Any of the aforementioned grounding layers, ground planes, or grounding metal layers are made of conductive materials. In one embodiment, the conductive material may be any of the following: 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, graphite-impregnated cloth, graphite-coated substrates, copper-plated substrates, brass-plated substrates, and aluminum-plated substrates. Those skilled in the art will understand that grounding layers / ground planes / grounding metal layers may also be made of other conductive materials.

[0227] Grounding: refers to coupling with the aforementioned ground / floor via a grounding structure and / or grounding circuit. In one embodiment, grounding can be achieved through physical grounding, such as through a structural component of the mid-frame to achieve physical grounding at a specific location on the frame (or, physical ground). In another embodiment, grounding can be achieved through device grounding, such as through devices like capacitors / inductors / resistors connected in series or parallel (or, device ground).

[0228] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings.

[0229] like Figure 1 As shown, the electronic device 100 may include: a cover 13, a 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 glass cover, but it may also be replaced with a cover made of other materials, such as a PET (Polyethylene terephthalate) cover.

[0230] The cover plate 13 can be set close to the display module 15, and can be mainly used to protect the display module 15 from dust.

[0231] In one embodiment, the display module 15 may include a liquid crystal display (LCD), a light emitting diode (LED) display panel, or an organic light-emitting diode (OLED) display panel, etc., and this application embodiment does not limit this.

[0232] The middle frame 19 mainly serves to support the entire machine. Figure 1The diagram shows PCB 17 positioned between the middle frame 19 and the back cover 21. It should be understood that in one embodiment, PCB 17 may also be positioned between the middle frame 19 and the display module 15; this application does not limit this. The printed circuit board PCB 17 can be made of flame-retardant material (FR-4) dielectric, Rogers dielectric, or a hybrid dielectric of Rogers and FR-4, etc. Here, FR-4 is a designation for a flame-retardant material grade, and Rogers dielectric is a high-frequency board. Components, such as radio frequency chips, are carried on PCB 17. In one embodiment, a metal layer can be provided on PCB 17. This metal layer can be used for grounding components carried on PCB 17, or for grounding other components, such as bracket antennas, frame antennas, etc. This metal layer can be called a ground plane, grounding plate, or grounding layer. In one embodiment, this metal layer can be formed by etching metal onto the surface of any dielectric layer in PCB 17. In one embodiment, the grounding metal layer can be located on the side of PCB 17 near the middle frame 19. In one embodiment, the edge of the printed circuit board PCB 17 can be considered as the edge of its ground plane. In one embodiment, the metal frame 19 can also be used for grounding the aforementioned components. The electronic device 100 may also have other ground planes / grounding layers, as previously described, and will not be repeated here.

[0233] Due to the compact nature of electronic devices, a ground plane / grounding layer is typically provided in the internal space 0-2mm from the inner surface of the frame (e.g., printed circuit boards, mid-frames, screen metal layers, batteries, etc. can all be considered part of the ground plane). In one embodiment, a medium is filled between the frame and the ground plane. The length and width of the rectangle formed by the inner surface contour of the filling medium can be simply considered as the length and width of the ground plane; alternatively, the length and width of the rectangle formed by the superimposed contour of all conductive parts inside the frame can be considered as the length and width of the ground plane.

[0234] 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 back cover 21, or between the middle frame 19 and the display module 15; this embodiment does not limit this. In some embodiments, the PCB 17 is divided into a motherboard and a daughterboard, and the battery may be disposed between the motherboard and the daughterboard. The motherboard may be disposed between the middle frame 19 and the upper edge of the battery, and the daughterboard may be disposed between the middle frame 19 and the lower edge of the battery.

[0235] The electronic device 100 may also include a frame 11, which may include a conductive material such as metal. The frame 11 may be disposed between the display module 15 and the back 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 secure the display module 15.

[0236] In one implementation, the frame 11, primarily composed of conductive material, can be referred to as the conductive frame or metal frame of the electronic device 100, suitable for industrial design (ID) with a metallic appearance. In another implementation, the outer surface of the frame 11 is primarily made of conductive material, such as metal, thus forming the appearance of a metallic frame. In these implementations, the conductive portion of the outer surface of the frame 11 can be used as an antenna radiator of the electronic device 100, and is commonly referred to as a frame antenna.

[0237] In another implementation, the outer surface of the frame 11 is primarily made of a non-conductive material, such as plastic, forming a non-metallic frame appearance suitable for non-metallic IDs. In another implementation, the inner surface of the frame 11 may include a conductive material, such as a metallic material. In this implementation, the conductive portion of the inner surface of the frame 11 can be used as an antenna radiator of the electronic device 100. It should be understood that the radiator (or the conductive material of the inner surface) disposed on the inner surface of the frame 11 can be attached to the non-conductive material of the frame 11 to minimize the volume occupied by the radiator and to be closer to the outside of the electronic device 100, achieving better signal transmission performance, and can also be referred to as a frame antenna. It should be noted that the antenna radiator being attached to the non-conductive material of the frame 11 means that the antenna radiator can be tightly attached to the inner surface of the non-conductive material, or it can be embedded inside the non-conductive material, or it can be 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 considered as part of the frame 11.

[0238] It should be understood that the frame 11 may have insulating gaps, with the conductive portion of the frame between the insulating gaps and / or between the insulating gaps and the grounding point serving as radiators, thereby forming a frame antenna (it should be understood that the radiator of the frame antenna may also include the conductive portion of the frame between the grounding point and the grounding point). 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 which case the gap is visible on the outer 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 (e.g., an end not electrically connected to other radiators or conductors), or as a gap formed between radiators on the inner surface of the frame 11, in which a non-metallic material (insulating material) may be provided, or it may not be provided with a non-metallic material, for example, filled with air, in which case the gap is not visible on the outer surface.

[0239] exist Figure 1 In subsequent embodiments, the electronic device 100's frame 11 is described using a metal frame (conductive frame) and a visible slit (an insulating slit visible on the surface). In this case, the metal frame serves as at least part of the antenna radiator. It should be understood that the same technical effect can be achieved when the electronic device 100's frame 11 is a non-metallic frame (a slit not visible on the surface), but for the sake of brevity, it will not be elaborated further.

[0240] The middle frame 19 may include the frame 11. The middle frame 19, including the frame 11, is a single unit that supports the electronic components in the device. The cover plate 13 and the rear cover 21 respectively cover the upper and lower edges of the frame to form the 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 may be collectively referred to as the housing of the electronic device 100. It should be understood that "housing" may refer to 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 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 transmit / receive radio frequency signals. This portion of the frame serving as the radiator may have gaps between it and the rest of the middle frame 19, thereby ensuring a good radiation environment for the antenna radiator. In one embodiment, the middle frame 19 may have an aperture at this portion of the frame serving as the radiator to facilitate antenna radiation.

[0242] Alternatively, the frame 11 may not be considered 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 inwardly extending protrusions to connect with the middle frame 19, for example, by means of spring clips, screws, welding, etc. The protrusions of the frame 11 can also be used to receive feed signals, so that at least a portion of the frame 11 acts as a radiator of the antenna to transmit / receive radio frequency signals. A gap may exist between this portion of the frame acting as the radiator and the middle frame 19, thereby ensuring that the antenna radiator has a good radiation environment, enabling the antenna to have good signal transmission capabilities.

[0243] The back cover 21 can be made of metal; it can also be made of non-conductive material, such as a glass back cover, a plastic back cover, or other non-metallic back cover; or it can be made of both conductive and non-conductive materials. In one embodiment, the back cover 21, which includes conductive material, can replace the middle frame 19 and form an integral part with the frame 11, providing support for the electronic components in the whole device.

[0244] In one embodiment, conductive portions in the mid-frame 19 and / or rear cover 21 can serve as a reference ground for the electronic device 100, wherein the frame 11, PCB 17, etc. of the electronic device can be grounded through electrical connection with the mid-frame.

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

[0246] Figure 2This is a schematic diagram of the structure of a foldable electronic device 100 provided in an embodiment of this application. The foldable electronic device 100 can be a mobile phone, tablet computer, e-reader, laptop computer, wearable device such as a watch, or other electronic device with folding function. Figure 2 The illustrated embodiment uses a foldable phone as an example.

[0247] It should be understood that, Figure 1 The diagram only shows an electronic device 100 including a single housing (e.g., the middle frame 19 described above). In actual production or design, the electronic device 100 may also include multiple housings to form a foldable electronic device 100.

[0248] refer to Figure 2 The foldable electronic device 100 may include a flexible display screen 110 (which may correspond to...) Figure 1 The display module 15 and the first border 121 (which can correspond to the display module 15) in the middle. Figure 1 The border 11), the first cover 122, and the second border 123 (which can correspond to) Figure 1 The first frame 121, the first cover 122, the second frame 123, and the second cover 124 can form a first housing 126 supporting the flexible display screen 110 (which can correspond to...). Figure 1 The middle frame 19) and the second housing 127 (which can correspond to) Figure 1 (The middle frame 19 in the middle). In other embodiments, at least one of the first cover 122 and the second cover 124 may include a display screen.

[0249] Figure 2 The dot matrix pattern in the center can schematically represent the flexible display screen 110. The flexible display screen 110 can be highly flexible and bendable, providing users with a new interaction method based on its bendable characteristics.

[0250] The flexible display screen 110 may include a first display section 111 corresponding to the first housing 126, a second display section 112 corresponding to the second housing 127, and a foldable display section 113 corresponding to the pivot 125. The foldable display section 113 may be connected between the first display section 111 and the second display section 112.

[0251] The first frame 121 may surround the outer periphery of the first cover 122, and at least a portion of the first frame 121 may also surround the outer periphery of the first display portion 111. The first display portion 111 may be arranged parallel to and spaced apart from the first cover 122, and the first display portion 111 and the first cover 122 may be located on opposite sides of the first frame 121. The space between the first display portion 111 and the first cover 122 may be used to house components of the foldable electronic device 100, such as antennas, circuit board assemblies, etc.

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

[0253] In one embodiment provided in this 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 connection method does not have to be an assembly method such as snap-fit, adhesive, welding, riveting, or clearance fit. The connection between the cover and the frame is usually difficult to separate. In another embodiment provided in this 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] A hinge 125 can connect the first housing 126 and the second housing 127. Under the action of the hinge 125, the first housing 126 and the second housing 127 can move closer to or further away from each other. Correspondingly, the first display portion 111 and the second display portion 112 of the flexible display screen 110 can move closer to or further away from each other, allowing the flexible display screen 110 to be folded or unfolded.

[0255] In one example, the pivot 125 may include a main shaft, a first connecting component, and a second connecting component. The first connecting component may be fixed to the first cover 122, and the second connecting component may be fixed to the second cover 124. The first and second connecting components are rotatable relative to the main shaft. Through the mutual movement of the first and second connecting components, the mutual movement of the first housing 126 and the second housing 127 can be driven, realizing the opening and closing function of the foldable electronic device 100.

[0256] Figure 2The foldable electronic device 100 shown is currently in one 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 following position: Figure 2 The flattened state shown.

[0257] The flexible display screen 110 being in a flattened state can be understood as the angle between the first display unit 111 corresponding to the first housing 126 and the second display unit 112 corresponding to the second housing 127 being 180 degrees. Due to possible errors in engineering implementation, the flexible display screen 110 can be considered to be in a flattened state when the angle between the first display unit 111 and the second display unit 112 is between 170° and 190°.

[0258] Figure 3 This illustrates one possible folded state of the foldable electronic device 100. Figure 3 The outward folding state of the foldable electronic device 100 is shown (the outward folding state can be simply referred to as the outward folding state). Figure 3 The outward folding state shown can be, for example, a left-right outward folding state or a top-bottom outward folding state. (The following is in conjunction with...) Figure 2 and Figure 3 This describes one possible folding state of the foldable electronic device 100.

[0259] In this embodiment, the foldable electronic device 100 being in a folded state means that the foldable electronic device 100 is currently bent, and the degree of bending of the foldable electronic device 100 reaches its maximum. At this time, the first cover 122 and the second cover 124 can be arranged approximately parallel, spaced apart from each other, and facing each other, and the distance between the first cover 122 and the second cover 124 is minimal. At least a portion of the first housing 126 and the second housing 127 are housed within the space enclosed by the flexible display screen 110; the first display portion 111, the first housing 126, the second housing 127, and the second display portion 112 are stacked sequentially. Similarly, the first display portion 111 and the second display portion 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 portion 111 and the second display portion 112. At this time, the first display portion 111 and the second display portion 112 can be considered to be located on different planes.

[0260] Combination Figure 2 and Figure 3When the foldable electronic device 100 is in the outward-folded state, the first cover 122 and the second cover 124 can approach each other, and the first display unit 111 and the second display unit 112 can approach each other. The first display unit 111, the second display unit 112, and the foldable display unit 113 can form a housing area for accommodating the first cover 122, the second cover 124, and the hinge 125. That is, the first cover 122, the second cover 124, and the hinge 125 can be accommodated in the space between the first display unit 111 and the second display unit 112.

[0261] It should be understood that the foldable electronic device 100 can be folded inward (the inward folded state can be simply referred to as the inward folded state). When the foldable electronic device 100 is in the inward folded state, the first cover 122 and the second cover 124 can be brought close to each other, and the first display unit 111 and the second display unit 112 can be brought close to each other. The first cover 122, the second cover 124, and the hinge 125 can form a housing area for accommodating the first display unit 111, the second display unit 112, and the foldable display unit 113. That is, the first display unit 111, the second display unit 112, and the foldable display unit 113 can be accommodated in the space between the first cover 122 and the second cover 124.

[0262] The foldable electronic device 100 can switch between a folded state and an unfolded state. When the foldable electronic device 100 is in the folded state, it occupies a relatively small space; when it is in the unfolded state, it can display a relatively large screen to increase the user's viewing area. It should be understood that the folded state includes the closed state, in which the foldable electronic device 100 occupies the least space; the unfolded state includes the flattened state, in which the foldable electronic device 100 occupies the most space.

[0263] The foldable electronic device 100 may also include a third housing 128 and a hinge 129, such as Figure 4 As shown. The hinge 129 can be connected between the third housing 128 and the second housing 127. The third housing 128 and the second housing 127 can be close to or far from each other. As the number of foldable parts of the foldable electronic device 100 increases, while maintaining the same screen size in the unfolded state, the space occupied by the foldable electronic device 100 can be further reduced in the folded state.

[0264] And in Figure 4 The foldable electronic device 100 shown has three foldable parts (first housing 126, second housing 127 and third housing 128), so the foldable electronic device 100 has at least three states: 1. unfolded state; 2. folded state; 3. partially unfolded state.

[0265] 1. For example Figure 4 The diagram shows one possible unfolded state of the foldable electronic device 100. 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 also be in the unfolded state.

[0266] 2. For example Figure 5 The diagram shows a possible folded state (tri-fold state) of the foldable electronic device 100. In the folded state, the first housing 126 and the second housing 127 rotate along the pivot 125, and the second housing 127 and the third housing 128 rotate along the pivot 129, maximizing the bending degree of the foldable electronic device 100. At this time, the first housing 126, the second housing 127, and the third housing 128 can be considered to be located on different planes.

[0267] It should be understood that, for the sake of a concise discussion, in Figure 5 In the illustrated structure, the foldable electronic device 100 is folded in an S-shape (the sides of the foldable electronic device 100 are S-shaped, and the second housing 127 is located between the first housing 126 and the third housing 128). In one embodiment, the foldable electronic device 100 can also be folded in a G-shape (the sides of the foldable electronic device 100 are G-shaped, and the third housing 128 is located between the first housing 126 and the second housing 127). This application does not limit the folding state of the foldable electronic device 100.

[0268] 3. For example Figure 6 The diagram illustrates one possible partially unfolded state (two-fold state) of the foldable electronic device 100. In the partially unfolded state, the angle between the first housing 126 and the second housing 127 can be approximately 180°. The second housing 127 and the third housing 128 rotate along the pivot 129, causing the third housing 128 to move closer to the second housing 127. At this time, the first housing 126 and the second housing 127 are considered to be on the same plane, while the second housing 127 and the third housing 128 can be considered to be on different planes. In another possible partially unfolded state, the angle between the third housing 128 and the second housing 127 can be approximately 180°. The first housing 126 and the second housing 127 rotate along the pivot 125, causing the first housing 126 to move closer to the second housing 127.

[0269] Figure 1 and Figure 2 The electronic device 100 and some components included in the foldable electronic device 100 are shown only schematically. The actual shape, size and construction of these components are not limited to the above figures.

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

[0271] It should be understood that, in the embodiments of this application, when a user holds (typically vertically and facing the screen) an electronic device, the orientation of the electronic device includes a top, bottom, left side, and right side.

[0272] First, by Figure 7 and Figure 8 This application will involve two antenna modes. Among them, Figure 7 This is a schematic diagram of the common-mode structure of an antenna provided in this application and the corresponding current and electric field distribution. Figure 8 This is a schematic diagram of the differential mode structure of another antenna provided in this application and the corresponding current and electric field distribution. Figure 7 and Figure 8 The antenna radiator is open at both ends, and its common-mode and differential-mode modes can be referred to as line common-mode and line differential-mode, respectively.

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

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

[0275] 1. Wire common mode (CM) mode

[0276] Figure 7 Figure (a) shows that the radiator of antenna 40 is open at both ends and connected to a feed circuit (not shown) at the middle position 41. In one embodiment, the antenna 40 is fed in a symmetrical feed configuration. The feed circuit can be connected to the middle position 41 of antenna 40 via feed wire 42. It should be understood that symmetrical feed can be understood as one end of the feed circuit being connected to the radiator and the other end being coupled to the ground to achieve grounding, wherein the connection point between the feed circuit and the radiator (feed point) is located at the center of the radiator, which may be, for example, the midpoint of the geometry, or the midpoint of the electrical length (or a certain area within a certain range near the aforementioned midpoint).

[0277] The middle position 41 of the antenna 40 may be, for example, the geometric center of the antenna, or the midpoint of the electrical length of the radiator, such as the connection point between the feed line 42 and the antenna 40, which covers the middle position 41.

[0278] Figure 7 (b) shows the current and electric field distribution of antenna 40. Figure 7 As shown in (b), the current exhibits an opposite distribution on both sides of the middle position 41, for example, a symmetrical distribution; the electric field exhibits a unidirectional distribution on both sides of the middle position 41. Figure 7 As shown in (b), the current at feeder line 42 exhibits a unidirectional distribution. Based on the unidirectional current distribution at feeder line 42, Figure 7 The type of feed shown in (a) can be called a line CM feed. This is based on the fact that the current is distributed in opposite directions on both sides of the connection between the radiator and the feed line 42. Figure 7 The antenna mode shown in (b) can be called the line CM mode (or simply CM mode; for example, for a line antenna, CM mode refers to the line CM mode). Figure 7 The current and electric field shown in (b) can be referred to as the current and electric field of the line CM mode, respectively.

[0279] The current is stronger at the middle position 41 of antenna 40 (the current is strongest near the middle position 41 of antenna 40), and weaker at both ends of antenna 40. Figure 7 As shown in (b) of the diagram. 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. Differential mode (DM)

[0281] like Figure 8 Image (a) shows that the two radiators of antenna 50 have open ends on both sides and are connected to a feed circuit at the middle position 51. In one embodiment, antenna 50 is fed using an anti-symmetrical feed. One end of the feed circuit is connected to one of the radiators via a feed wire 52, and the other end of the feed circuit is connected to the other radiator via a feed wire 52. The middle position 51 can be the geometric center of antenna 50, or the gap formed between the radiators.

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

[0283] Figure 8 (b) shows the current and electric field distribution of antenna 50. Figure 8 As shown in (b), the current in the antenna 50 is distributed in the same direction on both sides of the middle position 51, for example, an antisymmetric distribution; the electric field is distributed in opposite directions on both sides of the middle position 51. Figure 8 As shown in (b), the current at feeder line 52 exhibits a reverse distribution. Based on the reverse current distribution at feeder line 52, Figure 8 The type of feed shown in (a) can be called a line DM feed. This is based on the fact that the current is distributed in the same direction on both sides of the connection between the radiator and the feed line 52. Figure 8 The antenna mode shown in (b) can be called the line DM mode (or simply DM mode; for example, for a line antenna, DM mode refers to the line DM mode). Figure 8 The current and electric field shown in (b) can be referred to as the current and electric field in the line DM mode, respectively. It should be understood that this is based on the fact that the current is distributed in the same direction on both sides of the connection between the radiator and the feed line 52. Figure 8 The antenna mode shown in (b) can also be called the half-antenna mode, or the half-wavelength mode, or simply the half-mode.

[0284] In one embodiment, in online DM mode, or half-mode, the current is stronger at the middle position 51 of antenna 50 (the current peak is located near the middle position 51 of antenna 50), and weaker at both ends of antenna 50, such as... Figure 8 As shown in (b) of the diagram. The electric field is weaker at the middle position 51 of the antenna 50 and stronger at both ends of the linear antenna 50.

[0285] It should be understood that an antenna radiator can be considered as a metal structural component that generates radiation, and its quantity can be one, such as... Figure 7 As shown, or, it can be two items, such as Figure 8 As shown, adjustments can be made according to actual design or production needs. For example, for the line CM mode, it can also be as follows: Figure 8 The diagram illustrates the use of two radiators, positioned opposite each other with a gap between them. Symmetrical feeding is employed at the two ends closest to each other; for example, feeding the same feed source signal into both ends of the two radiators can achieve the same result as... Figure 7 The antenna structure shown achieves a similar effect. Correspondingly, for line DM mode, it can also be done as follows... Figure 7 The diagram illustrates a radiator with two feed points positioned at its center, using an anti-symmetrical feeding method. For example, by feeding signals of the same amplitude but opposite phase to the two symmetrical feed points on the radiator, a signal similar to [the one described above] can be obtained. Figure 8 The antenna structure shown has a similar effect.

[0286] 3. Line CM-DM mode

[0287] The above Figure 7 and Figure 8 The diagrams show how different feeding methods generate line CM mode and line DM mode when both ends of the radiator are open.

[0288] When the antenna uses asymmetrical feeding (the feed point is off-center from the radiator, including side-feed or offset feeding), or when the grounding point of the radiator (coupled to the ground) is asymmetrical (off-center from the radiator), the antenna can simultaneously generate a first resonance and a 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, with current and electric field distributions as follows: Figure 7 As shown in (b) above. The second resonance corresponds to the line DM mode, and the current and electric field distribution is as follows. Figure 8 As shown in (b) of the diagram.

[0289] Figure 9 This is a schematic diagram of a satellite communication application scenario provided in an embodiment of this application.

[0290] like Figure 9 As shown, when users conduct satellite communication through electronic devices, the area of ​​the antenna in the electronic device with better radiation characteristics needs to be pointed towards the satellite in order to achieve satellite connection (establish a communication connection with the satellite).

[0291] During satellite communication, if the relative position of the electronic device and the satellite changes (e.g., a low-Earth orbit satellite moves), while the user's grip on the electronic device remains unchanged, the maximum radiation direction of the antenna will deviate from the target radiation direction (e.g., the top of the electronic device, which can be understood as the direction from the bottom of the electronic device to the top). In this situation, the electronic device and the communication satellite cannot maintain a good alignment, resulting in poor communication quality or even dropped calls, greatly affecting the user's communication experience.

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

[0293] This application provides an electronic device including a first antenna and a second antenna. The operating frequency bands of the first antenna and the second antenna include satellite communication frequency bands. The first antenna and the second antenna can generate different maximum radiation directions. The electronic device can perform satellite communication by switching between the first antenna and the second antenna, or by simultaneously using both antennas, which can improve the user's experience when performing satellite communication.

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

[0295] Figure 10 This is a schematic diagram of an electronic device 100 provided in an embodiment of this application.

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

[0297] The first antenna 301 includes a first radiator 310 and a first feed circuit 311. The first radiator 310 includes a first feed point 312, and the first feed circuit 311 is coupled to the first feed point 312.

[0298] The second antenna 302 includes a second radiator 320 and a second feed circuit 321. The second radiator 320 includes a second feed point 322, and the second feed circuit 321 is coupled to the second feed point 322.

[0299] The operating frequency bands of the first antenna 301 and the second antenna 302 may both include at least a portion of the frequency bands in the satellite communication system. The electronic device 100 can perform satellite communication via the first antenna 301 and / or the second antenna 302.

[0300] Satellite communications include at least one of the following communication services: receiving and / or sending short messages (also known as short messages), making and / or answering telephone calls, and data services (such as Internet access).

[0301] In one embodiment, the satellite communication frequency band may include a portion of the frequency band in the Tiantong satellite system, specifically the transmitting frequency band (1980MHz-2010MHz) and receiving frequency band (2170MHz-2200MHz) within the Tiantong satellite system. In another embodiment, the satellite communication frequency band may include a portion of the frequency band in the BeiDou satellite system, specifically the transmitting frequency band (1610MHz-1626.5MHz) and receiving frequency band (2483.5MHz-2500MHz) within the BeiDou satellite system. In yet another embodiment, the satellite communication frequency band may include a portion of the frequency band in a low-Earth orbit (LEO) satellite system, specifically the transmitting frequency band (1668MHz-1675MHz) and receiving frequency band (1518MHz-1525MHz) within the LEO satellite system. Alternatively, it can be applied to other satellite communication systems, and this embodiment does not limit the scope of the application.

[0302] In one embodiment, when the first antenna 301 and / or the second antenna 302 are operating in the Tiantong satellite system (the operating frequency band of the first antenna 301 and / or the second antenna 302 includes at least a portion of the frequency bands in the Tiantong satellite system), the electronic device 100 can perform voice communication through the first antenna 301 and / or the second antenna 302. In one embodiment, when the first antenna 301 and / or the second antenna 302 are operating in the Beidou satellite system (the operating frequency band of the first antenna 301 and / or the second antenna 302 includes at least a portion of the frequency bands in the Beidou satellite system), the electronic device 100 can send or receive short messages and images through the first antenna 301 and / or the second antenna 302. In one embodiment, when the first antenna 301 and / or the second antenna 302 are operating in a 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 access 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 a base station.

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

[0304] In one embodiment, the satellite communication frequency band includes a first frequency band and a second frequency band. The first frequency band includes at least one transmitting frequency band within the satellite communication frequency band, and the second frequency band includes at least one receiving frequency band within the satellite communication frequency band. In one embodiment, the first feed circuit 311 is used to transmit radio frequency signals of the first frequency band or the second frequency band. In one embodiment, the second feed circuit 321 is used to transmit radio frequency signals of the first frequency band or the second frequency band.

[0305] It should be understood that, in the embodiments of this application, the feed circuit can be understood as a radio frequency channel of the radio frequency chip (RFIC) in the electronic device 100, used to generate the radio frequency signal fed into the antenna, or to process the radio frequency signal received by the antenna. A matching circuit (e.g., including at least one element) may also be provided between the feed circuit and the feed point of the radiator, which can be used to adjust the impedance between the feed circuit and the feed point of the radiator. In one embodiment, the first feed circuit 311 is used to generate the radio frequency signal of 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 may be used to switch the resonant 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 may be used to switch the operating frequency band of the first antenna 301 to include a first frequency band or a second frequency band. In one embodiment, the first tuning circuit 313 may 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 may include switching the grounding state of the radiator at the grounding end (e.g., the grounding state includes an open circuit, open circuit, or half-open circuit or half-open circuit state with respect to the ground), or switching the open state of the radiator at the open end (e.g., the open state also includes an open circuit, open circuit, or half-open circuit or half-open circuit state with respect to the ground).

[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 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 a first frequency band or a second frequency band. In one embodiment, the second tuning circuit 323 can be used to switch the operating mode of the second antenna 302, so that the second antenna 302 can support the first frequency band of its operating frequency band through different operating modes; or so that the second antenna 302 can support the second frequency band of its operating frequency band through different operating modes.

[0308] In one embodiment, the first frequency band may include at least a portion of the frequency band from 1.5 GHz to 4.5 GHz. In one embodiment, the first antenna 301 or the second antenna 302 operates on the Tiantong satellite system, and the first frequency band may include a transmission frequency band therein (e.g., 1980 MHz-2010 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates on the BeiDou satellite system, and the first frequency band may include a transmission frequency band therein (e.g., 1610 MHz-1626.5 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates on a low-Earth orbit satellite system (e.g., StarNet), and the first frequency band may include a transmission frequency band therein (e.g., 1668 MHz-1675 MHz).

[0309] In one embodiment, the second frequency band may include at least a portion of the frequency band from 1.5 GHz to 4.5 GHz. In one embodiment, the first antenna 301 or the second antenna 302 operates on the Tiantong satellite system, and the second frequency band may include a receiving frequency band therein (e.g., 2170 MHz - 2200 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates on the BeiDou satellite system, and the second frequency band may include a receiving frequency band therein (e.g., 2483.5 MHz - 2500 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates on a low-Earth orbit satellite system (e.g., StarNet), and the second frequency band may include a receiving frequency band therein (e.g., 1518 MHz - 1525 MHz).

[0310] It should be understood that when electronic device 100 conducts satellite communication, it can communicate with a communication satellite through an antenna within electronic device 100. In this case, different components can be loaded onto the antenna in different time slots to adjust the resonant frequency of the resonance point, thereby enabling the antenna to operate in the transmission and reception frequency bands of the satellite system in different time slots.

[0311] For the sake of brevity, the following embodiments of this application will be described using the example of the antenna of the electronic device 100 operating in the first frequency band for satellite communication. When the antenna operates in the second frequency band, the same understanding can be made, and will not be described in detail.

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

[0313] In one embodiment, the first feed point 312 on the first radiator 310 (or the second feed point 322 on the second radiator 320) receives the second radio frequency signal transmitted by the communication satellite and transmits it to the first feed circuit 311 (or the second feed 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 the signal from the communication satellite.

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

[0315] In one embodiment, at a first time / time period, the first feed point 312 (or the second feed point 322) receives a second radio frequency signal transmitted by a communication satellite, and the resonant frequency band of the resonance generated by the first radiator 310 (or the second radiator 320) includes the second frequency band, which may include at least one receiving frequency band in the 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] The difference between the first and second radiation patterns can be understood as the maximum radiation directions of the first and second radiation patterns being different. Alternatively, the difference between the first and second radiation patterns can be understood as the zero points of the first and second radiation patterns being different.

[0318] According to an embodiment of this application, since the first radiation pattern generated by the first antenna 301 and the second radiation pattern generated by the second antenna 302 are different, 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 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 the area where the first antenna 301 and / or the second antenna 302 have good radiation characteristics (e.g., the maximum radiation direction of the radiation pattern generated by the antenna at least partially overlaps with the target radiation direction), so as to maintain the alignment with the communication satellite and effectively improve the user experience.

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

[0320] In one embodiment, electronic device 100 transmits signals to a communication satellite via a single antenna, or receives signals transmitted by the communication satellite via multiple antennas (e.g., first antenna 301 and second antenna 302). During a first time period, electronic device 100 performs satellite communication in a first frequency band via first antenna 301. During a second time period, electronic device 100 performs satellite communication in the first frequency band via second antenna 302. During a third time period, electronic device 100 performs satellite communication in a second frequency band via first antenna 301 and second antenna 302 respectively. For example, when the communication satellite is always located in an area where first antenna 301 has good radiation characteristics, electronic device 100 transmits signals to the communication satellite via first antenna 301 in the first frequency band. Alternatively, first antenna 301 and second antenna 302 receive signals transmitted by the communication satellite in the second frequency band respectively.

[0321] In one embodiment, electronic device 100 performs satellite communication via multiple antennas (e.g., first antenna 301 and second antenna 302). During a first time period, electronic device 100 performs satellite communication in a first frequency band via first antenna 301 and second antenna 302. During a second time period, electronic device 100 performs satellite communication in a second frequency band via first antenna 301 and second antenna 302. For example, communication between electronic device 100 and communication satellites via multiple antennas (e.g., first antenna 301 and second antenna 302) includes transmitting signals to the communication satellite via the multiple antennas (e.g., first antenna 301 and second antenna 302) in the first frequency band and receiving signals transmitted by the communication satellite via the multiple antennas (e.g., first antenna 301 and second antenna 302) in the second frequency band.

[0322] It should be understood that the signals received by the electronic device 100 from the communication satellite in the second frequency band through multiple antennas (e.g., the first antenna 301 and the second antenna 302) can be superimposed by algorithms and other means 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 via 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 feed circuit 311 and the second feed circuit 321 may be identical. In one embodiment, the first feed circuit 311 and the second feed circuit 321 include the same radio frequency channel in the radio frequency chip. In one embodiment, the circuit portion of the first feed circuit 311 from the radio frequency channel to the first feed point 312 and the circuit portion of the second feed circuit 321 from the radio frequency channel to the second feed point 322 include at least partially identical electronic components, such as a power amplifier (PA), a low noise amplifier (LNA), etc.

[0324] In one embodiment, when the electronic device 100 performs satellite communication via multiple antennas, the electronic device 100 simultaneously performs satellite communication via the first antenna 301 and the second antenna 302, and the first feed circuit 311 and the second feed circuit 321 are different. In one embodiment, the first feed circuit 311 and the second feed circuit 321 include different radio frequency channels in the radio frequency chip. In one embodiment, the circuit portion of the first feed circuit 311 from the radio frequency channel to the first feed point 312 and the circuit portion of the second feed circuit 321 from the radio frequency channel to the second feed point 322 include at least partially different electronic components, such as PA, LNA, etc.

[0325] It should be understood that when the electronic device 100 performs satellite communication through multiple antennas, unlike an antenna array (e.g., a phased array antenna) that includes multiple radiators, the first antenna 301 and the second antenna 302 perform satellite communication as independent antennas. For example, the first antenna 301 and the second antenna 302 are independently fed, and the first antenna 301 and the second antenna 302 do not need to be provided with a shared power divider phase shifter circuit to make the radio frequency signals fed into the first antenna 301 and the second antenna 302 have different phase differences.

[0326] Figure 11 This is a schematic diagram of another electronic device 100 provided in the embodiments of this application.

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

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

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

[0330] The first frame 210 includes a first side 131 and a second side 132 intersecting 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. Wherein, 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 pivot 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 pivot is substantially parallel to the extension direction of the second side.

[0331] It should be understood that the first edge 131 can be the top edge or the bottom edge of the electronic device 100. For the sake of brevity, only the example of the first edge 131 being the top edge of the electronic device 100 will be used. The top / bottom edge of the electronic device 100 can be understood as the top / bottom edge in normal use. For example, in a mobile phone, it can be understood as the top / bottom edge of the desktop or 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 a conductive portion of a first frame 210 between a first position 201 and a second position 202. At least a portion of the first radiator 310 is spaced apart from the ground 300. The first antenna 301 also includes a first feed circuit 311, and the first radiator 310 includes a first feed point 312, with the first feed circuit 311 coupled to the first feed 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 ground 300. The second antenna 302 also includes a second feed circuit 321, and the second radiator 320 includes a second feed point 322, with the second feed circuit 321 coupled to the second feed 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 can 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 extension direction (e.g., the z-direction) of the second side 132 is greater than or equal to 20 mm and less than or equal to half 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 part (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 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, 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 performance 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 towards the second radiator 320 in the top direction, allowing the electronic device 100 to have good communication characteristics over a larger angle range with respect to the top direction.

[0340] In this embodiment of the 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] The upper hemisphere region can be understood as the area within a range where the angle with the top direction is less than or equal to 90°. In the coordinate system, it can be understood as the region in the positive direction of the xoy plane towards the z direction.

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

[0343] In one embodiment, the first frame 210 has a first insulating gap at a first position 201 and is coupled to the floor 300 at a second position 202, such as Figure 12 As 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, where the manufacturing process allows, the width of the first insulating gap can be even smaller, or conductive material can be disposed inside the first insulating gap while still achieving a similar antenna radiation effect. The widths of the gaps on the frame in the embodiments of this application are all within the above range, and for the sake of brevity, they will not be elaborated further. Here, "width of the insulating gap" can be simply understood as the dimension in the direction extending between two conductive materials (e.g., two radiators).

[0345] It should be understood that in this embodiment, the description only uses the example of the first frame 210 including the first position 201, the second position 202, the third position 203, and the fourth position 204 arranged in sequence. In actual production or design, the arrangement may not follow this order. For example, the first position 201 may also be located between the second position 202 and the third position 203. At the same time, the first frame 210 is coupled to the floor 300 at the first position 201 and has a second insulating gap at the second position 202, which can also form a similar structure (the radiator has a structure with one end grounded and the other end open). For the sake of brevity, similar structures will not be described in detail, and they can all be understood accordingly in this embodiment.

[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 between a first connection point 341 and a second connection point 342.

[0348] It should be understood that the first radiator 310 has a structure with one end grounded and the other end open. Furthermore, the fifth insulating gap in the first radiator 310 can be considered as an equivalent capacitance (e.g., distributed capacitance) on the first radiator 310, which allows 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 the fifth insulating gap is added. In one embodiment, the dielectric loss near the first radiator 310 forming the metamaterial structure is reduced, thus effectively improving the radiation characteristics (e.g., system efficiency and radiation efficiency) of the first antenna 301.

[0349] Furthermore, by coupling the first element 331 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 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 grounded and the other end open. Because the region near the open end has a stronger magnetic field, Figure 10 The first tuning circuit shown can be positioned close to the open end (second position 202) of the first radiator 310 so that the resonant frequency of the resonance generated by the first antenna 301 has a larger adjustment range.

[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 (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 this application have the same structure (the radiator has a structure with one end grounded and the other end open), the setting of the tuning circuit can be understood accordingly, and will not be described in detail.

[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 a 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., no reversal occurs). The electrical length of the first radiator 310 increases from one-quarter of the first wavelength to more than three-eighths of the first wavelength, but it still operates in a quarter-wavelength mode.

[0355] In this configuration, the current density on the first radiator 310 is dispersed, and the electric field density between the first radiator 310 and the ground 300 is reduced. This reduces conductor and dielectric losses caused by the first radiator 310 and the conductors and dielectrics surrounding it, thereby improving the radiation characteristics of the first antenna 301. Increasing the radiating aperture of the first radiator 310 effectively improves the system efficiency and radiation efficiency of the first antenna 301.

[0356] The first wavelength can be understood as the vacuum wavelength corresponding to the resonant frequency of the first resonance generated by the first radiator 310, or it can 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, one end at the second position 202) and the fifth insulating gap is less than the length of the first radiator 310 between the second end (open end, one end at the first position 201) and the fifth insulating gap.

[0359] It should be understood that the length of the radiator between one end of the first radiator 310 and the fifth insulating gap can be understood as the length of the conductor portion between the end of that end and the fifth insulating gap. For the sake of brevity, this can be understood accordingly in the embodiments of this application.

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

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

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

[0363] It should be understood that the aforementioned fifth insulating gap can be located in the region of the first radiator 310 where the current is relatively large. The region of large current should be understood as, relative to the first radiator 310 without the gap (e.g., operating in quarter-wavelength mode), when the fifth insulating gap is present, the electric field strength of the first radiator 310 is weakened, achieving the effect of dispersing the electric field, thereby improving the radiation characteristics of the first antenna 301 (e.g., system efficiency and radiation efficiency).

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

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

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

[0368] It should be understood that by designing the equivalent capacitance or equivalent inductance of the first element 331 according to the frequency of the resonant point of different resonances, the current distribution on the first radiator 310 can be more dispersed, conductor losses can be reduced, the radiation aperture of the first radiator 310 can be increased, 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] 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 via a connector (e.g., a metal spring), the distance to the fifth insulating gap can be understood as the minimum distance between the center of the portion of the connector that contacts 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 also includes a second element 332, which is coupled between the third connection point 343 and the ground plane 300.

[0372] It should be understood that the first radiator 310 is electrically connected to the ground 300 at the third connection point 343 via the second element 332. This allows the current in the first radiator 310 to be shunt in the region near the third connection point 343 when the first radiator 310 achieves its first resonance. This shunt in the region near the third connection point 343 disperses the current density on the first radiator 310. In one embodiment, the more dispersed current distribution on the first radiator 310 reduces its conductor loss. In another embodiment, the more dispersed current distribution on the first radiator 310 increases its radiating aperture. The reduced conductor loss and increased radiating aperture of the first radiator 310 improve the radiation characteristics of the first antenna 301 (e.g., system efficiency and radiation efficiency).

[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 (e.g., 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 0mm, the third connection point 343 coincides with the first connection point 341 and / or the second connection point 342.

[0375] The antenna described in this application embodiment, when its operating mode includes a quarter-wavelength mode (one end of the antenna is an open end and the other end is a ground end), can transmit signals through a circuit with a grounded terminal. Figure 12 The structure of the first antenna 301 shown gives the antenna better radiation characteristics (e.g., radiation efficiency). For example, Figure 12 The second antenna 302 shown is Figure 15 The second antenna 302 shown is Figure 20 The first antenna 301 shown in (a) is Figure 20 The second line 302 is shown in (b) in the middle. Figure 41 The first antenna 301 and the second antenna 302 shown are illustrated. Figure 42 The first antenna 301 and the second antenna 302 shown are examples of this. For the sake of brevity, they will not be described in detail here.

[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 below. Figure 13 As shown.

[0377] In one embodiment, the distance between the first feed point 312 and the first position 201 (the length of the first border 210 between the first feed point 312 and the first position 201) and the distance between the first feed point 312 and the second position 202 (the length of the first border 210 between the first feed point 312 and the second position 202) are different.

[0378] It should be understood that the first resonance generated by the first radiator 310 is produced by the line DM mode described in the above embodiments. The radiation pattern generated by the line DM mode does not have a strong current flowing towards the ground plane 300; therefore, the current exciting the ground plane 300 is small. The effect of the ground plane 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 of the electronic device 100 (the direction in which the first radiator 310 is away from the ground plane, for example, the z-direction). However, the radiation pattern generated by the line CM mode has a stronger current flowing towards the ground plane 300; therefore, the current exciting the ground plane 300 is large, and the ground plane 300 has a greater impact on the radiation pattern generated by the antenna. Therefore, the radiation pattern generated by the line CM mode is not mainly oriented towards the top of the electronic device 100 (the direction in which the first radiator 310 is away from the ground plane, for example, the z-direction).

[0379] Furthermore, in satellite communication bands, the efficiency (e.g., radiation efficiency) of antennas resonating using the line DM mode can meet the requirements of satellite communication. For example, when the first radiator 310 extends in a straight line, both conductor loss and dielectric loss are relatively small under the action of the same current, resulting in higher efficiency (e.g., radiation efficiency) for the first antenna 301. In contrast, the line CM mode has greater losses due to the reverse current on the radiator, leading to lower efficiency (e.g., radiation efficiency) for antennas resonating using the line CM mode.

[0380] In one embodiment, because the region near the open end has a stronger magnetic field, Figure 10 The tuning circuit shown can be positioned near the open end (first position 201 or second position 202) of the first radiator 310, allowing for greater adjustment range at the resonant frequency generated by the first antenna 301. Both ends of the first radiator 310 are open, and the first feed point 312 and the connection point between the tuning circuit and the radiator are located on opposite sides of the virtual axis of the first radiator 310.

[0381] In this embodiment, the center of the first radiator 310 can be located on a virtual axis, and the lengths of the first radiators 310 on both sides of the virtual axis are the same. It should be understood that the two sides of the virtual axis in this embodiment can be understood as the two sides of the plane formed by the virtual axis and the thickness direction of the electronic device 100 (e.g., the direction perpendicular to the display screen) (e.g., the x-direction). Meanwhile, due to manufacturing design requirements, the edge of the frame 11 facing the floor 300 (facing the interior of the electronic device 100) is not flat. Therefore, in this embodiment, 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 extension 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 (first position 201 or 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 this application have the same structure (both ends of the radiator are open), the relevant information of the tuning circuit can be understood accordingly, and will not be described in detail here.

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

[0385] In one embodiment, the first radiator 310 may further include a first grounding point 351, such as Figure 14 As shown. The first radiator 310 is coupled to the ground 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 of the center of the first radiator 310, and the length of the first radiator 310 on both sides of the center is 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 at the first grounding point 351 using a grounding element. The width of the grounding element 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 element includes at least a portion of the central region of the first radiator 310, the first grounding point 351 can be considered to be 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 ground 300 at the first ground point 351, the first radiator 310 can also generate a second resonance in the line CM mode, which can be used to improve the radiation characteristics (e.g., radiation efficiency) of the first antenna 301 in the first and / or second frequency bands.

[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-quarter 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-quarter of the length of the first radiator 310.

[0392] It should be understood that the first grounding point 351 can be located in a region close to the center of the first radiator 310 to better excite the first radiator 310 to generate line CM mode and line DM mode. Furthermore, when the first grounding point 351 is located in a region close to the center of the first radiator 310, it is easier to adjust the frequency difference between the resonances generated by the line CM mode and the line DM mode, giving the first antenna 301 better radiation characteristics. For the sake of brevity, the grounding points on the radiators described in the embodiments of this application can all be understood accordingly and will not be elaborated further.

[0393] In one embodiment, the resonant frequency of the first resonance may be higher than the resonant frequency of the second resonance. The ratio between the resonant frequency of the first resonance and the resonant frequency of the second resonance may be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the ratio between the resonant frequency of the first resonance and the resonant frequency of the second resonance may 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 resonant frequency of the first resonance and the resonant frequency of the second resonance can be greater than or equal to 100MHz and less than or equal to 500MHz.

[0395] It should be understood that in the first frequency band (or the second frequency band), the first antenna 301 can operate in 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 resonant frequency band of the first resonance.

[0396] In one embodiment, the resonant frequency of the first resonance may be higher than the resonant frequency of the second resonance. The ratio between the resonant frequencies of the first and second resonances may be less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band is greater than the resonant frequency of the second resonance and less than the resonant 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 line CM mode and line DM mode, and the radiation is generated by both line CM mode and line DM mode. The first antenna 301 simultaneously has some radiation characteristics of line CM mode and some radiation characteristics of line DM mode.

[0398] In one embodiment, the ratio between the resonant frequency of the first resonance and the resonant frequency of the second resonance is less than or equal to 1.2. In another embodiment, the frequency difference between the resonant frequency of the first resonance and the resonant 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, such as Figure 15 As shown.

[0400] The first radiator 310 includes a fourth connection point 344. A first switch branch 361 and a second switch branch 362 are coupled between the fourth connection point 344 and the floor 300 via a first switch 360. In one embodiment, a first connection port of the first switch 360 is coupled to the first switch branch 361, and a 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 considered to be connected in parallel. In one embodiment, the first switch branch 361 and the second switch branch 362 are connected in parallel between the floor 300 and the fourth connection point 344. In another embodiment, both the first switch branch 361 and the second switch branch 362 are connected in parallel between the floor 300 and the fourth connection point 344 via the first switch 360.

[0402] It should be understood that the switches described in this application, such as a "first switch," may include one or more switching devices; the connection points described in this application, such as a "fourth connection point," may include one or more connection points. In one embodiment, the first switch branch 361 may be coupled between the floor 300 and the first radiator 310 through one switching device in the first switch and one connection point in the fourth connection point 344; the second switch branch 362 may be coupled between the floor 300 and the first radiator 310 through another switching device in the first switch and another connection point in the fourth connection point 344. In the embodiments of this application, the switches are only used for switching to different switch branches coupled to the radiator / parasitic branch, and their specific locations and forms are not limited.

[0403] It should be understood that, in the embodiments of this application, the switch branch can be understood as the circuit between the switch and the connection point (e.g., the fourth connection point 344) or the ground 300, which can be switched to different switch branches by the switch, so that the equivalent capacitance, equivalent resistance or equivalent inductance coupled to the connection point are different.

[0404] In one embodiment, the first tuning circuit described above may include a first switch branch 361, a second switch 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 ground plane 300. In one embodiment, the first antenna 301 may further include a third switch branch, which can be used to adjust the resonant frequency of the resonance generated by the first antenna 301, enabling the first antenna 301 to operate in different satellite communication frequency bands. For example, 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 includes the first frequency band; when the fourth connection point 344 is coupled to the third switch 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, a switching branch may include one or more components, which may be connected in series or in parallel to achieve different equivalent capacitance and / or equivalent inductance and / or equivalent resistance values. In another embodiment, the switching branch may also include a switch, which switches the equivalent capacitance and / or equivalent inductance and / or equivalent resistance values ​​under different states of the switching branch.

[0406] In one embodiment, the switch branch may not include any components. The switch branch can be used to determine the boundary conditions at the fourth connection point. For example, the switch branch may be in an open-circuit state when the switch common port is connected to the switch branch, resulting in an open-circuit state at the fourth connection point 344 (not coupled to the ground plane 300 via a device). Alternatively, the switch branch may be in a short-circuit state when the switch common port is connected to the switch branch, resulting in a short-circuit state at the fourth connection point 344 (connected to the ground plane 300 branch, without any other components). For the sake of brevity, ... Figure 14 In the electronic device 100 shown, only the first switch branch 361 and the second switch branch 362, which include equivalent elements, are described as examples.

[0407] In one embodiment, the first feed point 312 and the fourth connection point 344 are located on opposite sides of the virtual axis of the first radiator 310. In this case, the first radiator 310 may or may not include the first ground 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 aforementioned first frequency band (or 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 the embodiments of this application (e.g., in Figure 14 In the electronic device 100 shown, the example of the first antenna 301 being in the same operating state is used for explanation. The same operating state can be understood as the operating frequency band of the first antenna 301 including either the first frequency band or the second frequency band. When the first switch 360 is coupled to the first switch branch 361 or the second switch branch 362, the first antenna 301 can communicate in the corresponding frequency band.

[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 floor 300.

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

[0414] It should be understood that, for the sake of brevity, this embodiment of the application only uses the example of the fourth connection point 344 being located on the first side of the virtual axis and the first power supply point 312 being located on the second side of the virtual axis for illustration. In actual production or application, the fourth connection point 344 may also be located on the second side of the virtual axis and the first power supply point 312 may 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 (e.g., current intensity, current density) on the ground 300 on the first side of the virtual axis is greater than the current on the ground 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 the first frequency band or the 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 the first frequency band or the second frequency band, and the current (e.g., current intensity, current density) on the ground 300 on the first side of the virtual axis is less than the current on the ground 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 the first frequency band or the 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 floor 300 described in the embodiments of this application can be understood as the current near the edge of the floor 300 close to the radiator / parasitic branch, for example, the current within a distance of 30mm 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 toward 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 toward 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, thus enabling the first antenna 301 to have good radiation characteristics over a larger area.

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

[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 to the coupling of the first switch branch 361 to the fourth connection point 344, the current on the floor 300 on the first side of the virtual axis is weakened, and the current on the floor 300 on the second side of the virtual axis is strengthened.

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

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

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

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

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

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

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

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

[0433] In one embodiment, when the first switch branch 361 is coupled to the fourth connection point 344, the frequency difference between the resonant frequency of the first resonance generated by the first antenna 301 and the resonant frequency of the second resonance is a first frequency difference. When the second switch branch 362 is coupled to the fourth connection point 344, the frequency difference between the resonant frequency of the first resonance generated by the first antenna 301 and the resonant frequency of the second resonance is a 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 a first threshold, and the second frequency difference is greater than the first threshold. In one embodiment, the first threshold is 300MHz. In one embodiment, the first threshold is 250MHz. In one embodiment, the first threshold is 200MHz. In one embodiment, the first threshold is 150MHz.

[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 resonant frequency of the resonance generated by the line CM mode and the resonant frequency of the resonance generated by the line DM mode.

[0436] When the second switch branch 362 is coupled to the fourth connection point 344, compared to the coupling of the first switch branch 361 to the fourth connection point 344, the frequency difference between the resonant frequency of the resonance generated by the line CM mode and the resonant frequency of the resonance generated by the line DM mode increases. This results in a decrease in the current on the first side of the virtual axis's ground plane 300 and an increase in the current on the second side of the virtual axis's ground plane 300. Conversely, when the first switch branch 361 is coupled to the fourth connection point 344, compared to the coupling of the second switch branch 362 to the fourth connection point 344, the frequency difference between the resonant frequency of the resonance generated by the line CM mode and the resonant frequency of the resonance generated by the line DM mode decreases. This results in an increase in the current on the first side of the virtual axis's ground plane 300 and a decrease in the current on the second side of the virtual axis's ground plane 300.

[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 aforementioned range, and the fourth connection point 344 is coupled to either the first switch branch 361 or the second switch branch 362, the current on the ground plane 300 on the first side of the virtual axis differs more from the current on the ground plane 300 on the second side of the virtual axis, thereby increasing the difference between the first radiation pattern and the second radiation pattern (e.g., increasing the angle between the maximum radiation directions), which can further widen the beamwidth of the first antenna 301. The first antenna 301 has a wider beamwidth, enabling it to have good communication characteristics over a wider angular range (the angle with respect to the top direction).

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

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

[0441] Furthermore, since there is usually a strong current in the area near the feed point, when the first feed point 312 can be located near the second antenna 302, it is easier to enhance the current on the ground 300 on the second side of the virtual axis, causing the maximum radiation direction of the pattern generated by the first antenna 301 to deflect away from the second antenna 302, making the difference between the patterns of the first antenna 301 and the second antenna 302 greater, thereby enabling the electronic device 100 to have good communication characteristics over a wider range of angles (angles with the top direction).

[0442] It should be understood that the antenna described in the embodiments of this application, when the antenna's operating mode includes the line DM mode (where both ends of the antenna are open), can communicate with... Figure 15 The first antenna 301 shown has a similar structure to achieve the switching between the first and second radiation patterns. For example, Figure 13 The first antenna 301 and the second antenna 302 shown are illustrated. Figure 14 The first antenna 301 and the second antenna 302 shown are illustrated. Figure 20 The second line 302 is shown in (a) in the middle. Figure 20 The first antenna 301 shown in (b) and (c) is Figure 25 The first antenna 301 shown is Figure 31The first antenna 301 shown is Figure 38 The first antenna 301 and the second antenna 302 shown are illustrated. Figure 39 The first antenna 301 and the second antenna 302 shown are examples of this. For the sake of brevity, they will not be described in detail here.

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

[0444] In one embodiment, the first frame 210 is coupled to the floor 300 at a third position 203 and has a fourth insulating gap at a fourth position 204, such as Figure 15 As 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-type antenna or a left-hand antenna. The left-hand antenna can, for example, be an antenna that conforms to a composite right and left hand (CRLH) transmission line structure.

[0446] When the second radiator 320 forms an inverted F-type antenna, the second feed point 322 is close to the ground end, and the distance between the second feed point 322 and the ground end (the length of the second radiator 320 between the second feed point 322 and the third position 203) is less than or equal to half the length of the second radiator 320.

[0447] When the second radiator 320 is formed similarly to a left-handed antenna, the second feed point 322 is close to the open end, and the distance between the second feed point 322 and the ground end (the length of the second radiator 320 between the second feed point 322 and the third position 203) is greater than or equal to half the length of the second radiator 320. When the second feed point 322 is close to the open end, it facilitates the miniaturization of the second radiator 320. The coupling connection between the second feed circuit 321 and the second feed point 322 is a capacitor to better excite the second radiator 320.

[0448] For the sake of brevity, the formation of structures similar to an inverted F-type antenna or a left-handed antenna can be understood in the embodiments of the application, and will not be described in detail here.

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

[0450] In one embodiment, the first frame 210 further includes a fifth position 205, with a fourth position 204 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 branch 330. The first parasitic branch 330 includes a conductive portion of the first border 210 between the fifth position 205 and the fourth position 204.

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

[0453] In one embodiment, when the first parasitic branch 330 generates a parasitic resonance close to the second resonance generated by the second radiator 320 (the frequency difference between the resonance point of the parasitic resonance and the resonance point of the second resonance is less than or equal to 300MHz and greater than or equal to 100MHz), 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 first parasitic stub 330 generates a parasitic resonance that is far removed from the second resonance generated by the second radiator 320 (the frequency difference between the resonant point of the parasitic resonance and the resonant point of the second resonance is greater than or equal to 300MHz), the first parasitic resonance 330 can be used to enhance the beamwidth 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 give the second antenna 302 better communication characteristics over a larger angle range between the side of the first parasitic stub 330 and 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 embodiments, the first parasitic branch 330 and the second radiator 320 are opposite to each other through the fourth insulating gap and do not contact each other (the open ends are close to each other). In actual production or design, the first parasitic branch 330 and the second radiator 320 can also be connected through the third position 203 (the grounding ends are close to each other).

[0457] It should be understood that all antennas described in this application may include parasitic stubs, which can be used to improve the radiation characteristics of the antenna (e.g., beamwidth, radiation efficiency, etc.). For the sake of brevity, these will not be elaborated further.

[0458] In one embodiment, the first frame 210 is coupled to the floor 300 at a third position 203 and has a fourth insulating gap at a 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 insulating gap between the fifth connection point 345 and the sixth connection point 346, as shown. Figure 12 As 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 grounded and the other end open. Similarly, Figure 12 In the electronic device 100 shown, the second radiator 320 can also form a metamaterial structure. For the sake of brevity, it will not be described in detail. You can refer to the metamaterial structure in the above embodiments for understanding.

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

[0462] In one embodiment, the distance between the second feed point 322 and the third position 203 (the length of the first border 210 between the second feed point 322 and the third position 203) is different from the distance between the second feed point 322 and the fourth position 204 (the length of the first border 210 between the second feed 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, and similarly, it can be understood with reference to the corresponding description in the above embodiments.

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

[0465] In one embodiment, the second radiator 320 may further include a second grounding point 352, such as Figure 14 As shown. The second radiator 320 is coupled to the ground 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 of the center of the second radiator 320, and the length of the second radiator 320 on both sides of the center is 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 at the second grounding point 352 using a grounding element. The width of the grounding element connected to 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 element includes at least a portion of the central region of the second radiator 320, the second grounding point 352 can be considered to be 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 ground 300 at the second grounding point 352, the second radiator 320 can also generate a fourth resonance in the line CM mode, which can be used to improve the radiation characteristics (e.g., radiation efficiency) of the second radiator 302 in the first and / or second frequency bands.

[0471] In one embodiment, the resonant frequency of the third resonance can be higher than the resonant frequency of the fourth resonance. The ratio between the resonant frequencies of the third and fourth resonances can be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the ratio between the resonant frequencies of the third and fourth resonances 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 resonant frequency of the third resonance and the resonant frequency of the fourth resonance can be greater than or equal to 100MHz and less than or equal to 500MHz.

[0473] It should be understood that in the first (or second) frequency band, the second antenna 302 can operate in 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 resonant frequency band of the third resonance.

[0474] In one embodiment, the resonant frequency of the third resonance can be higher than the resonant frequency of the fourth resonance. The ratio between the resonant frequencies of the third and fourth resonances can be less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band is greater than the resonant frequency of the fourth resonance and less than the resonant 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 mixed mode of line CM mode and line DM mode, and the radiation is generated by both line CM mode and line DM mode. The second antenna 302 simultaneously has some radiation characteristics of line CM mode and some radiation characteristics of line DM mode.

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

[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 of the first antennas 301 and any of the second antennas 302 shown can be any combination of the first antenna 301 and the second antenna 302.

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

[0479] For example, when the first antenna 301 and the second antenna 302 are Figure 13 or Figure 14 The radiator shown does not include the grounding point, as shown in the figure. Figure 14 The illustrated or radiating body includes the grounding point, such as Figure 14 The first antenna 301 (shown) and the second antenna 302 are shown. The first antenna 301, located at the top, operates in line DM mode, with the electrical length of the entire stub approximately half a wavelength. One end of the first radiator 310 is fed, and the other end is tuned via a capacitor or inductor. The middle region of the first radiator 310 can be grounded or unconnected. When the middle region of the first radiator 310 is grounded, the resonance generated in the line CM mode is tuned before the resonance generated in the line DM mode, ensuring that the resonance of the first antenna during operation is exactly in line DM mode, resulting in optimal radiation efficiency and an end-fire radiation pattern towards the top. Similarly, the second antenna 302, located at the waist, is also fed at one end of the second radiator 320, and the other end is tuned via a capacitor or inductor. The middle region of the second radiator 320 can be grounded or unconnected. When the middle region of the second radiator 320 is grounded, the resonance generated in the line CM mode is tuned before the resonance generated in the line DM mode, ensuring that the resonance of the second antenna during operation is exactly in 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 pattern complementarity, wide beam coverage can be achieved by combining the two antennas.

[0480] When the first antenna 301 and the second antenna 302 are Figure 14The first antenna 301 and the second antenna 302 shown in the diagram have a coverage null on the left side of the combined radiation pattern. To enhance left-side coverage, an unbalanced line DM mode is introduced in the design of the first antenna 301 located at the top. Figure 15 The first antenna 301 shown is used to adjust the resonance generated by the linear CM mode to a position further forward than the resonance generated by the linear DM mode. This causes the current generated by the linear DM mode to be biased to the right, resulting in a right-stronger, left-weak current pattern. Consequently, the radiation pattern is shifted to the left. Combining this radiation pattern with the second antenna 302 located at the waist of the antenna yields a radiation pattern that covers the top side, left side (left of the top direction), and right side (top direction). 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 that of the second radiator 320.

[0482] In this context, "same structure" can be understood as "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 perform satellite communication by switching the first antenna 301 and the second antenna 302, or simultaneously perform satellite communication by using the first antenna 301 and the second antenna 302, which can achieve good communication quality over a larger area.

[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 shown are presented. Figure 16 yes Figure 14 Simulation results of the S-parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown. Figure 17 yes Figure 14 Simulation results of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown.

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

[0486] like Figure 16 As shown, the first antenna (S11) can resonate near 2.05 GHz and 2.2 GHz. The resonance near 2.05 GHz corresponds to the second resonance in the above embodiment, and the resonance near 2.2 GHz corresponds to the first resonance in the above embodiment. The resonant frequency band of the first resonance can include the second frequency band mentioned above.

[0487] The second antenna (S22) can resonate around 1.95 GHz and 2.15 GHz. The resonance around 1.95 GHz corresponds to the fourth resonance in the above embodiment, and the resonance around 2.15 GHz corresponds to the third resonance in the above embodiment. The resonant frequency band of the third resonance can include the second frequency band mentioned above.

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

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

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

[0491] When the first and second antennas in an electronic device operate simultaneously, in the second frequency band (e.g., 2170MHz-2200MHz), the radiation efficiency of the first antenna decreases by approximately 0.4dB, and the radiation efficiency of the second antenna decreases by approximately 0.4dB.

[0492] Figure 18 and Figure 19 yes Figure 14 The radiation patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown. Figure 18 yes Figure 14 The first radiation pattern generated by the first antenna 301 in the electronic device 100 shown. Figure 19 yes Figure 14 The second radiation pattern generated by the second antenna 302 in the electronic device 100 shown.

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

[0494] like Figure 19 As shown, the maximum radiation direction of the second radiation pattern generated by the second antenna is toward the side 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. Electronic devices can switch between the first antenna and the second antenna (or, the first antenna and the second antenna work simultaneously) to ensure that the communication satellite is always in the area where the electronic devices have good radiation characteristics.

[0496] Figure 20 This is a schematic diagram of another electronic device 100 provided in an embodiment of this application.

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

[0498] The first housing 211 includes a first frame 210, at least a portion of which is spaced apart from the floor 300. The second housing 212 includes a second frame 220, at least a portion of which 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 rotatably 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.

[0500] It should be understood that, Figure 20 In the illustrated electronic device 100, the electronic device 100 is a foldable electronic device. A first rotating shaft 213 is directly connected to a first housing 211 and a second housing 212, allowing the first housing 211 and the second housing 212 to rotate relative to each other. Furthermore, "the first rotating shaft 213 is rotatably connected to the first housing 211 and the second housing 212" includes the case where the first rotating shaft 213 can be rotatably connected to the first or second housing via 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 housings, and is rotatably connected to both the first housing 211 and the intermediate housings, allowing the first housing 211 and the intermediate housings to rotate relative to each other. The second rotating shaft is located between the intermediate housings and the second housing 212, and the first rotating shaft 213 is rotatably connected to both the intermediate housings and the second housing 212, allowing the intermediate housings and the second housing 212 to rotate relative to each other.

[0501] It should be understood that Figure 20 The electronic device 100 shown is Figures 11 to 15 The only difference between the electronic devices 100 shown is whether or not they can be folded.

[0502] like Figure 20 As 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 of the first antennas shown. The second antenna 302 can be... Figures 12 to 15 Any of the second antennas shown.

[0504] In one embodiment, the first antenna 301 can be a metamaterial structure (e.g., Figure 12 The first antenna 301 shown can be a structure with both ends open and including a second ground point 352 (e.g., Figure 14 The second line (302) shown is as follows. Figure 20 As shown in (a) in the figure.

[0505] In one embodiment, the first antenna 301 may be a structure with open ends and not including the first ground point 351 (e.g., Figure 13 The first antenna 301 shown can be a metamaterial structure (e.g., Figure 12 The second line (302) shown is as follows. Figure 20 As shown in (b) of the diagram.

[0506] In one embodiment, the first antenna 301 may be a structure with open ends and including a first ground point 351 (e.g., Figure 14 The first antenna 301 shown can be a structure with both ends open and not including the second grounding point 352 (e.g., Figure 13 The second line (302) shown is as follows. Figure 20 As shown in (c) in the figure.

[0507] It should be understood that, for the sake of brevity, in Figure 20 In the electronic device 100 shown, only the first antenna 301 is used. Figures 12 to 15 The first antenna 301 and the second antenna 302 shown in the figure are Figures 12 to 15 Let's take the second line 302 shown in the image as an example for illustration.

[0508] For the sake of brevity, Figures 12 to 15 The first antenna 301 and the second antenna 302 shown are... Figure 20The similar parts of the first antenna 301 and the second antenna 302 shown will not be described in detail. For example, 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 feed point 312; the position of the second feed point 322; the relationship between the first frequency band and the second frequency band; the equivalent inductance or equivalent capacitance values ​​of the corresponding components when the first radiator 310 and the second radiator 320 are metamaterial structures; the positions of the connection points on the radiators; etc.

[0509] Figure 21 and Figure 22 yes Figure 20 Simulation results of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) are provided. Figure 21 yes Figure 20 Simulation results of the S-parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) are shown. Figure 22 yes Figure 20 Simulation results of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in (a) are shown.

[0510] like Figure 21 As shown, the first antenna (S11) can resonate around 2.15 GHz, which corresponds to the first resonance in the above embodiment.

[0511] The second antenna (S22) can resonate near 2.1 GHz and 2.3 GHz. Resonance near 2.1 GHz corresponds to the fourth resonance in the above embodiment, and resonance near 2.3 GHz corresponds to the third resonance in the above embodiment. The center frequency of the second frequency band is greater than the resonant frequency of the fourth resonance and less than the resonant frequency of the third resonance. In the second frequency band, the second antenna radiates using both line CM and line DM modes.

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

[0513] It should be understood that, Figure 21 The simulation results shown in the figure illustrate the S-parameters at the same frequency (2.2 GHz), which is located in the second frequency band (e.g., 2170 MHz - 2200 MHz). In actual simulation and debugging results, the depth of the S-parameters may vary; generally, a depth of 3 dB or more is considered sufficient to provide communication functionality.

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

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

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

[0517] It should be understood that, Figure 22 The simulation results shown in the graph illustrate the radiative efficiency at the same frequency (2.2 GHz), which is located in the second frequency band (e.g., 2170 MHz - 2200 MHz). In actual simulation and debugging results, the radiative efficiency curves may differ; generally, a value greater than -8 dB is considered sufficient to provide communication functionality.

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

[0519] like Figure 23 As shown, due to Figure 20 In the electronic device 100 shown, the floor is relatively large. Due to the current generated on the floor, the maximum radiation direction of the first radiation pattern generated by the first antenna is directed toward the top of the electronic device (e.g., the z-direction) and deflected toward the housing on the side where the first antenna is not located (deflected toward the second housing side).

[0520] like Figure 24 As shown, the maximum radiation direction of the second radiation pattern generated by the second antenna is toward the top direction of the electronic device (e.g., the z direction), and it has 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. Electronic devices can switch between the first antenna and the second antenna (or, the first antenna and the second antenna work simultaneously) to ensure that the communication satellite is always in the area where the electronic devices have good radiation characteristics.

[0522] Figure 25 This is a schematic diagram of another electronic device 100 provided in the embodiments of this application.

[0523] like Figure 25 As shown, the second radiator 320 includes a second grounding point 352, which 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 back cover 21 of the electronic device 100 can be understood as the second radiator 320 being located on the surface of the back cover 21, or being disposed on the surface of the back cover 21 through other structural components. Alternatively, the second radiator 320 being attached to the back cover 21 of the electronic device 100 can also be understood as the second radiator 320 being disposed adjacent to the back cover 21 in the electronic device 100. Here, "adjacent" can be understood as, for example, the distance between the second radiator 320 and the back cover 21 being within 5 mm, or the distance between the second radiator and the back cover 21 being within 3 mm. In one embodiment, the second radiator 320 may be located on one side of the plane of the back cover 21.

[0525] In one embodiment, the second radiator 320 may be located inside the rear cover 21 (on the side closer to PCB 17), such as... Figure 26 As shown. In one embodiment, the second radiator 320 may be located between the back cover 21 and the PCB 17. In one embodiment, the electronic device 100 may further include a bracket 251, with the second radiator 320 located on the surface of the bracket 251. In one embodiment, a shielding cover 15 may be disposed between the bracket 251 and the PCB 17. In one embodiment, electronic components may be disposed within the shielding cover 15 to prevent 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 outer surface of the electronic device 100, it has a more flexible layout.

[0527] In one embodiment, the second radiator 320 may be located outside the rear cover 21 (on the side away from PCB 17), such as... Figure 27As shown. In one embodiment, the second radiator 320 may be a decorative piece of the camera module 252 of the electronic device 100, which 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 located outside the electronic device 100, the radiation environment of the second radiator 302 is better (e.g., larger clearance and greater distance from the electronic components mounted on the PCB17), and the second radiator 302 has better radiation characteristics (e.g., radiation efficiency).

[0529] In one embodiment, the distance (e.g., the maximum distance) between the first radiator 310 and the second radiator 320 along the extension direction (e.g., the z-direction) of the second side 132 is less than or equal to half 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 part (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 that Figure 25 The electronic device 100 shown is Figures 11 to 15 ,as well as Figure 20 The electronic device 100 shown differs only in the structure and position of the second radiator 320. In the above embodiment, the second radiator 320 includes a conductor portion of the first frame 210 between the third position 203 and the fourth position 204, which are located on the second side 132. Figure 25 In the electronic device 100 shown, the second radiator 320 is a conductor attached to one side of the rear cover 21. Figure 25 The first antenna 301 in the electronic device 100 shown can be Figures 11 to 15 In the electronic device 100 shown, any type of first antenna 301 is used. For the sake of brevity, in this embodiment, only the first antenna 301 is used. Figure 14 The first antenna 301 shown in the diagram will be explained in detail, and will not be described in detail again.

[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, 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 performance 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 towards the second radiator 320 in the top direction, allowing the electronic device 100 to have good communication characteristics over a larger angle range with respect to the top direction.

[0533] The upper hemisphere region can be understood as the area within a range where the angle with the top direction is less than or equal to 90°. In the coordinate system, it can be understood as the region in the positive direction of the xoy plane towards the z direction.

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

[0535] It should be understood that the second radiator 320 can be strip-shaped (e.g., the ratio of length to width is greater than or equal to 3), circular, trapezoidal, triangular, etc. The embodiments of this 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 described in detail here.

[0536] In one embodiment, the second radiator 320 can be formed in 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 (e.g., the ratio of the length to the width of the radiator is less than or equal to 10), and the radiator is set face-to-face with the ground (e.g., the plane on which the radiator is located is approximately parallel to the plane on which the ground is located).

[0538] In one embodiment, the second radiator 320 can be used to generate a third resonance and a fourth resonance. The resonant frequency of the third resonance is higher than that of the fourth resonance, and the ratio between the resonant frequencies of the third and fourth resonances 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 resonant frequency of the fourth resonance and less than the resonant frequency of the third resonance.

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

[0540] In one embodiment, the second radiator 320 includes a first centerline, the second feed point 322 and the center (e.g., geometric center) of the second radiator 320 are located on the first centerline, the first centerline divides the second radiator 320 into a first part and a second part, a second grounding point 352 is located in the first part, and a third grounding point 353 is located in the second part. It should be understood that when the second radiator 320 is annular or circular, the center can be understood as the center of the circle; when the second radiator 320 is quadrilateral, the center can be understood as the intersection of the diagonals; and when the second radiator 320 has 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 embodiments, the linear CM mode or linear DM mode can be understood as the linear antenna primarily generating radiation from current. Conversely, the CM mode or DM mode of the patch antenna can be understood as the patch antenna primarily generating radiation from magnetic current (e.g., the magnetic field between the radiator and the ground).

[0543] like Figure 29 As shown in (a), in the CM mode of the patch antenna, the current on the second radiator 320 is reversed on both sides of the virtual ground line (the second ground point 352 and the third ground point 353 are located on the virtual ground line). When the second radiator 320 includes only one ground point, it can be understood that the ground point is closer to the second feed point 322 and farther away from the second feed point 322.

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

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

[0546] like Figure 29As shown in (d), in the CM mode of the patch antenna, the radiation produced by the second antenna has two strong regions, which are biased towards the top of the electronic device 100 (from bottom to top, e.g., the positive z-direction) and the bottom of the electronic device 100 (from top to bottom, e.g., the negative z-direction). The radiation produced by the second antenna in the thickness direction of the electronic device 100 (e.g., the x-direction) is weaker (having null points on the radiation pattern, e.g., the region where the gain is low at 2%).

[0547] In the CM mode of the patch antenna, the electric field between the second radiator 320 and the ground plane 300 is in the same direction on both sides of the virtual ground wire, but partially reversed in the far field of the second radiator 320 (for example, this can be understood by the partially reversed electric field in the circumferential direction indicated by the curved arrow). Figure 29 As shown in (e) in the diagram. Therefore, the electric field of the first stronger radiation region in the radiation pattern generated by the second antenna can be set to be biased towards the top of the electronic device 29 (the direction from the bottom edge to the top edge, e.g., the positive direction of the z direction) and the electric field of the second stronger radiation region can be biased towards the bottom of the electronic device 29 (the direction from the top edge to the bottom edge, e.g., the negative direction of the z direction), wherein the far field of the first and second stronger radiation regions has at least partially opposite electric field components (e.g., there is an opposite electric field component in the z direction).

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

[0549] like Figure 30 As shown in (b), when the second radiator is in a ring shape, in DM mode, the currents on the second radiators 320 on both sides of the second ground point 352 are in the same direction, the currents on the second radiators 320 on both sides of the third ground point 353 are in the same direction, and the currents on the second radiators 320 between the second ground point 352 and the third ground point 353 are in opposite directions.

[0550] like Figure 30 As shown in (c), in the DM mode of the patch antenna, the electric field between the second radiator 320 and the ground plane 300 is reversed on both sides of the virtual ground line.

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

[0552] In the DM mode of the patch antenna, the electric field between the second radiator 320 and the ground plane 300 is opposite on both sides of the virtual ground wire, but in the same direction in the far field of the second radiator 320 (e.g., this can be understood by the fact that the circumferential electric field is basically in the same direction, as indicated by the curved arrow). Figure 30 As shown in (e). Therefore, the radiation pattern produced by the second antenna is in the same direction as the electric field 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 z-direction) and the bottom direction (e.g., the positive 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 resonant frequency of the fourth resonator and less than the resonant frequency of the third resonator. In the first frequency band, the second antenna 302 radiates jointly by the CM mode and the DM mode of the patch antenna.

[0554] Since the radiation pattern generated by the CM mode of the patch antenna has electric field components that are at least partially opposite in the two stronger radiation regions, and the radiation pattern generated by the DM mode of the patch antenna has electric fields that are in the same direction in the stronger radiation regions, 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, by generating radiation in both CM and DM modes of the patch antenna, can enhance the radiation pattern generated by the second antenna 302 in the top direction (e.g., the positive z-direction) and weaken the radiation in the bottom direction (e.g., the positive z-direction), thereby giving the second antenna 302 better radiation characteristics in the top direction and enabling the electronic device 100 to have better communication performance.

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

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

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

[0559] It should be understood that when the resonant point of the third resonance is close to the resonant point of the fourth resonance, the second antenna 302 has better radiation characteristics in the first frequency band (or the second frequency band) (e.g., the proportion of radiation towards 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 another 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 feed point 312 and the second feed point 322 is less than or equal to 20 mm. In another embodiment, the distance between the first feed point 312 and the second feed 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 by electrical connection, the distance between the first feed point 312 and the second feed point 322 can be understood as the distance between the center of the area where the first metal part and the first radiator 310 contact each other for feeding the first antenna 301 and the center of the area where the second metal part and the second radiator 320 contact each other for feeding the second antenna 302.

[0563] When both the first radiator and the second radiator are fed in an indirect coupling manner, the distance between the first feed point 312 and the second feed point 322 can be understood as the distance between the center of the projection of the end of the first metal member used to feed the first antenna 301 toward the first radiator 310 onto the first radiator 310 (along the extension direction perpendicular to the first radiator 310) and the center of the projection of the end of the second metal member used to feed the second antenna 302 toward the second radiator 320 onto the second radiator 320 (along the direction of the thickness of the electronic device 100).

[0564] When the first radiator 310 and the second radiator 320 are powered by electrical connection and indirect coupling respectively, the above embodiments can be referred to for understanding.

[0565] When the distance between the first feed point 312 and the second feed point 322 is close, the transmission line distance between the RF channel (e.g., the first feed circuit 311 and the second feed circuit 321) in the RF chip and the corresponding feed point (e.g., the first feed point 312 or the second feed point 322) is short. The loss of the RF signal output by the RF channel on this transmission path is small, which is beneficial to improving the radiation characteristics (e.g., gain) of the antenna (first antenna 301 or second antenna 302).

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

[0567] It should be understood that, in one embodiment, the fourth element 334 coupled between the floor 300 and the seventh connection point 347 can be used to switch the radiation characteristics (e.g., maximum radiation direction) of the second antenna 302 in the first frequency band (or second frequency band). The fourth element 334 can adjust the frequency difference between the resonant points of the third and fourth resonators. This causes the center frequency of the first frequency band (or second frequency band) to be relatively close to the resonant point of the third or fourth resonator, thereby adjusting the radiation characteristics (e.g., maximum radiation direction) of the second antenna 302 in the first frequency band (or second frequency band). The fourth element 334 coupled between the floor 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 between the seventh connection point 347 and the second feed point 322 is greater than or equal to 45°. In one embodiment, the angle between the seventh connection point 347 and the second feed point 322 is greater than or equal to 90°. In one embodiment, the angle between the seventh connection point 347 and the second feed point 322 is greater than or equal to 135°.

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

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

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

[0572] The second antenna 302 may also include a switch 340 and multiple components, such as Figure 32 As shown. In one embodiment, the second antenna 302 may include a fourth element 334 and a fifth element 335.

[0573] For the sake of brevity, in Figure 32 In the illustrated electronic device 100, only the single-pole fourth-throw (DPFT) switch 340 is used as an example for illustration. In actual production or design, it can be replaced. For example, the switch 340 can be a double-pole Xthrow (DPXT), or an Xpole Xthrow (XPXT), or a combination of multiple single-pole single-throw (SPST) switches. This application embodiment does not limit this, and the switches described in this application embodiment can be understood accordingly.

[0574] The switch 340 is coupled between the seventh connection point 347 and the floor 300. Multiple elements (e.g., the fourth element 334 and the fifth element 335) may be coupled between the switch 340 and the floor 300 or between the switch 340 and the seventh connection point 347.

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

[0576] It should be understood that, Figure 31 The illustrated electronic device 100 may include only one element (e.g., a fourth element 334). While... Figure 32 The electronic device 100 shown includes multiple components (e.g., fourth component 334 and fifth component 335). The equivalent capacitance or equivalent inductance value of the component coupled between the seventh connection point 347 and the ground 300 can be switched by the switch 340. Alternatively, the boundary conditions of the seventh connection point 347 can be switched by the switch 340. For example, the seventh connection point 347 can be disconnected from the ground 300, or the seventh connection point 347 can be directly electrically connected to the ground 300 (without any component). The frequency difference between the resonant point of the third resonance and the resonant point of the fourth resonance can be adjusted.

[0577] By adjusting the frequency difference between the resonant points of the third and fourth resonators, the center frequency of the first frequency band can be made relatively close to the resonant points of the third or fourth resonators. For example, the fourth element 334 and the second radiator 320 are used to generate the third resonator 1 and the fourth resonator 1. The fifth element 335 and the second radiator 320 are used to generate the third resonator 2 and the fourth resonator 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 resonant point frequency of the third resonator 1, and the second frequency difference is the frequency difference between the center frequency of the first frequency band and the resonant point frequency of the third resonator 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 resonant point frequency of the fourth resonator 1, and the fourth frequency difference is the frequency difference between the center frequency of the first frequency band and the resonant point frequency of the fourth resonator 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 floor 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, Figure 31 The illustrated electronic device 100 may include only one element (e.g., a fourth element 334). While... Figure 32 The illustrated electronic device 100 includes multiple components (e.g., a fourth component 334 and a fifth component 335). A switch 340 can switch the equivalent capacitance or equivalent inductance value of the components coupled between the seventh connection point 347 and the ground plane 300. Alternatively, the switch 340 can switch the boundary conditions of the seventh connection point 347; for example, the seventh connection point 347 can be disconnected from the ground plane 300, or directly electrically connected to the ground plane 300 (without any components). The resonant frequencies of the third and fourth resonances can be adjusted. For example, the fourth component 334 and the second radiator 320 are used to generate the third resonance 1 and the fourth resonance 1. The fifth component 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 resonant frequency of the fourth resonance 1 and greater than the resonant frequency of the third resonance 1. The center frequency of the second frequency band is less than the resonant frequency of the fourth resonance 2 and greater than the resonant 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, thereby enabling antenna reuse. For example, the second antenna can also be used as a cellular antenna, a WiFi antenna, etc., which will not be elaborated further.

[0582] It should be understood that, Figures 25 to 28 as well as Figure 31 and Figure 32 In the illustrated electronic device 100, the first antenna 301 located at the top and Figures 12 to 15 The first antenna 301 shown is the same and will not be described again. The second antenna 302, attached to the rear cover 21 of the electronic device 100, can be simplified as a patch antenna with grounded center. Its overall electrical size is half a wavelength. The upper end of the second radiator 320 (closer to the first radiator 310) is fed, and the lower end of the second radiator 320 is tuned by connecting a capacitor or inductor. By adjusting the resonant device generated by the CM mode of the patch antenna, the resonance generated by the CM mode of the patch antenna is tuned before the resonance generated by the DM mode, so that the second antenna 302 has a current combination of the CM mode and the DM mode of the patch antenna in the operating frequency band. This causes the current distribution on the second radiator 320 to be biased towards the upper hemisphere region (the region close to the first radiator 310), and its radiation pattern is also a superposition of the radiation patterns generated by the CM mode and the DM mode of the patch antenna, with a radiation pattern mainly radiating towards the top. Therefore, superimposing the radiation patterns of the first antenna 301 and the second antenna 302 located at the top can obtain better merging benefits.

[0583] Furthermore, since the second radiator 320 of the second antenna 302 does not include the conductive portion of the first frame, the system cost incurred due to compatibility design when the conductive portion of the first frame is reused as both a satellite antenna and a cellular antenna can be reduced.

[0584] For the sake of brevity, Figures 12 to 15 The first antenna 301 and the second antenna 302 shown are... Figure 20 The similar parts of the first antenna 301 and the second antenna 302 shown will not be described in detail. For example, 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 feed point 312; the relationship between the first frequency band and the second frequency band; the equivalent inductance or equivalent capacitance value of the corresponding element when the first radiator 310 is a metamaterial structure; the position of the connection point on the radiator; etc.

[0585] Figure 33 and Figure 34 yes Figure 31 The simulation results of the first antenna 301 and the second antenna 302 in the electronic device 100 shown are presented. Figure 33 yes Figure 31 Simulation results of the S-parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown. Figure 34 yes Figure 31 Simulation results of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown.

[0586] like Figure 33 As shown, the first antenna (S11) can resonate near 1.95 GHz and near 2.2 GHz. The resonance near 1.95 GHz corresponds to the second resonance in the above embodiment, and the resonance near 2.2 GHz corresponds to the first resonance in the above embodiment.

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

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

[0589] like Figure 34 As shown, when the first antenna and the second antenna in the electronic device operate simultaneously, in the second frequency band (e.g., 2170MHz-2200MHz), the radiation efficiency of the first antenna is approximately -2.2dB, and the radiation efficiency of the second antenna is approximately -4.7dB.

[0590] It should be understood that, Figure 34 The simulation results shown in the graph illustrate the radiative efficiency at the same frequency (2.2 GHz), which is located in the second frequency band (e.g., 2170 MHz - 2200 MHz). In actual simulation and debugging results, the radiative efficiency curves may differ; generally, a value greater than -8 dB is considered sufficient to provide communication functionality.

[0591] Figure 35 and Figure 36 yes Figure 31 The radiation patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown. Figure 35 yes Figure 31 The first radiation pattern generated by the first antenna 301 in the electronic device 100 shown. Figure 36 yes Figure 32 The second radiation pattern generated by the second antenna 302 in the electronic device 100 shown.

[0592] like Figure 35 As shown, the maximum radiation direction of the first pattern generated by the first antenna is towards the top of the electronic device (e.g., the z-direction), and the first antenna has good radiation characteristics in the vicinity of the top direction.

[0593] like Figure 36 As shown, since the center frequency of the second frequency band is greater than the resonant frequency of the fourth resonance and less than the resonant frequency of the third resonance, in the first frequency band, the second antenna is radiated by the CM mode and DM mode of the patch antenna. The radiation pattern generated by the second antenna is enhanced in the top direction (e.g., the z direction), which can better facilitate communication with communication satellites.

[0594] Figure 37 This is a schematic diagram of another electronic device 100 provided in the embodiments of this application.

[0595] like Figure 37 As shown, the electronic device 100 may include a first border 210.

[0596] The first border 210 includes a first position 201, a second position 202, a third position 203, and a fourth position 204 arranged sequentially. At least a portion of the first border 210 is spaced apart from the floor 300.

[0597] It should be understood that the sequential arrangement described in the embodiments of this application can be interpreted as an arrangement in sequence. For example, the sequential arrangement of the first position 201, the second position 202, and the third position 203 can be understood as the first position 201, the second position 202, and the third position 203 being arranged in sequence, with the third position 203 not located between the first position 201 and the second position 202, but the second position 202 and the third position 203 can overlap. For the sake of brevity, the sequential arrangement described in the embodiments of this application can all be understood accordingly, and will not be elaborated further.

[0598] The overlap 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, or the second position 202 and the third position 203 being the same location. For the sake of brevity, the overlaps mentioned in the embodiments of this application can all be understood accordingly, and will not be elaborated further.

[0599] Specifically, the first frame 210 has an insulating gap or is coupled to the floor 300 at a first position 201. The first frame 210 has an insulating gap or is coupled to the floor 300 at a second position 202. The first frame 210 has an insulating gap or is coupled to the floor 300 at a third position 203. The first frame 210 has an insulating gap or is coupled to the floor 300 at a fourth position 204.

[0600] The first frame 210 includes a first side 131, a second side 132 intersecting the first side 131 at an angle, and a third side 133 intersecting the first side 131 at an angle. The length of the first side 131 is less than the length of the second side 132. The length of the first side 131 is less than the length of the third side 133. In one embodiment, the first side 131 can be understood as the short side of the electronic device 100.

[0601] The electronic device 100 includes a first antenna 301 and a second antenna 302.

[0602] 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 can perform satellite communication through the first antenna 301 and / or the second antenna 302.

[0603] The first radiator 310 of the first antenna 301 includes a conductive portion of a first frame 210 between a first position 201 and a second position 202. At least a portion of the first radiator 310 is spaced apart from the ground 300. The first antenna 301 also includes a first feed circuit 311, and the first radiator 310 includes a first feed point 312, with the first feed circuit 311 coupled to the first feed point 312.

For example, the second antenna 302 can be used to enhance the radiation of the electronic device 100 towards the second radiator 320 in the top direction, and the electronic device 100 can have good communication characteristics over a larger angle range with respect to the top direction.

[0608] The upper hemisphere region can be understood as the area within a range where the angle with the top direction is less than or equal to 90°. In the coordinate system, it can be understood as the region in the positive direction of the xoy plane towards the z direction.

[0609] In one embodiment, the first radiator 310 can be used to generate a first resonance, the resonant frequency band of which includes the first frequency band and / or the second frequency band described above.

[0623] It should be understood that when the first radiator 310 is coupled to the ground 300 at the first ground point 351, the first radiator 310 can also generate a second resonance in the line CM mode, which can be used to improve the radiation characteristics (e.g., radiation efficiency) of the first antenna 301 in the first and / or second frequency bands.

[0624] At the same time, the structural strength of the electronic device 100 can be improved by coupling the grounding component with the ground 300.

[0632] In one embodiment, the second position 202 and the third position 203 coincide.

[0633] In one embodiment, similarly, in Figure 40 In the first antenna 301 shown, the first radiator 310 may also include a first grounding point 351, but for the sake of brevity, it will not be described in detail.

[0634] In one embodiment, the first position 201 is located on the first side 131. The first frame 210 is coupled to the floor 300 at the first position 201 and has a second insulating gap at the second position 202, such as... Figure 41 As shown.

[0635] In one embodiment, one end of the first radiator 310 is an open end and the other end is a ground end, forming a structure similar to an inverted F-type antenna or a left-handed antenna.

[0636] When the first radiator 310 forms an inverted F-type antenna, the first feed point 312 is close to the ground end, and the distance between the first feed point 312 and the ground end (the length of the first radiator 310 between the first feed point 312 and the first position 201) is less than or equal to half the length of the first radiator 310.

[0637] When the first radiator 310 is formed to resemble a left-handed antenna, the first feed point 312 is close to the open end, and the distance between the first feed point 312 and the ground end (the length of the first radiator 310 between the first feed point 312 and the first position 201) is greater than or equal to half the length of the first radiator 310. When the first feed point 312 is close to the open end, it facilitates the miniaturization of the first radiator 310. The coupling connection between the first feed circuit 311 and the first feed point 312 is a capacitor to better excite the first radiator 310.

[0638] For the sake of brevity, the formation of structures similar to an inverted F-type antenna or a left-handed antenna can be understood in the embodiments of the application, and will not be described in detail here.

The first frame 210 has an insulating gap at sixth position 206 or is coupled to the floor 300.

[0642] It should be understood that, for the sake of brevity, this application embodiment only uses the example of a frame 210 having an insulating gap at the fifth position 205 and being coupled to the floor 300 at the sixth position 206 for illustration.

[0644] It should be understood that the first parasitic stub 371 is used to generate the first parasitic resonance, which can be used to suppress the current on the ground 300 near the second side 132, thereby reducing the component of the radiation pattern corresponding to the first resonance in the bottom direction of the electronic device 100 (the direction from the top of the electronic device 100 to the bottom), thereby increasing the component of the radiation pattern in the top direction of the electronic device 100, and improving the radiation characteristics (e.g., gain) of the first antenna 301 in the top direction.

[0645] In one embodiment, a signal is fed into the first feed circuit 311, a first radiator 310 is used to generate a first primary resonance, and a first parasitic stub 371 is used to generate a first parasitic resonance. The first primary resonance and the first parasitic resonance together form the aforementioned first resonance (since the frequency difference between the resonance point of the first parasitic resonance and the resonance point of the first primary resonance is small, in the S-parameter diagram, the first primary resonance and the first parasitic resonance merge into one resonance). In one embodiment, the resonance point of the first parasitic resonance is located within the resonance frequency band of the first primary resonance. In one embodiment, the frequency difference between the resonance point frequency of the first parasitic resonance and the resonance point frequency of the first primary resonance is less than or equal to 100MHz.

In one embodiment, the resonance point frequency of the first parasitic resonance may be less than the resonance point frequency of the first primary resonance.

[0646] Meanwhile, in this embodiment, the coupling between the first radiator 310 and the first parasitic stub 371 is weak, and it cannot effectively excite the first parasitic resonance. Therefore, a pit corresponding to the first parasitic resonance does not appear clearly in the S-parameter plot. However, since the first parasitic resonance is partially excited by current, a noticeable pit will appear in the efficiency curve (e.g., radiation efficiency or system efficiency). For example, if an efficiency pit appears at the first frequency point, then the first frequency point can be considered to correspond to the resonance point of the aforementioned first parasitic resonance. In one embodiment, the efficiency (e.g., radiation efficiency or system efficiency) reduction caused by the pit does not exceed 1.5 dB. In another embodiment, the efficiency (e.g., radiation efficiency or system efficiency) reduction caused by the pit does not exceed 1 dB.
