Technical Field

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

[0003] Currently, existing terminal electronic devices use the frame as an antenna radiator. For example, in satellite communication systems, frame radiators are primarily used to form linearly polarized antennas. When using satellite communication, users need to point the antenna's area with good radiation characteristics (for example, the antenna's gain within this area is greater than or equal to AdBic, where A is the minimum gain required to meet communication requirements in the satellite communication system) toward the satellite to achieve satellite alignment (establishing a communication connection with the satellite).

[0004] However, during satellite communications, the relative position of the electronic device and the satellite changes. For example, if a low-orbit satellite moves, the satellite may move beyond the antenna's optimal radiation area. In this case, the user needs to adjust their grip or move the device to keep the satellite within the antenna's optimal radiation area to maintain tracking or establish a connection with a new satellite. Failure to do so can result in poor communication quality or even disconnection, significantly impacting the user's communication experience. Summary of the Invention

[0005] The present application provides an electronic device comprising a first antenna and a second antenna. The operating frequency band of the first antenna and the operating frequency band of the second antenna include a satellite communication frequency band. 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 using the first antenna and the second antenna simultaneously, thereby improving the user experience during satellite communication.

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

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

[0008] In combination with the first aspect, in certain 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 the present application, the resonance generated by the first radiator is generated by a linear DM mode. The directional pattern generated by the linear DM mode does not have a strong current flowing to the floor. Therefore, the current excited in the floor is small. The influence of the floor on the directional pattern generated by the linear DM mode is similar to that of a reflector. As a result, the directional pattern generated by the linear DM mode is mainly toward the top of the electronic device (the direction in which the first radiator is away from the floor, for example, the z direction). In contrast, the directional pattern generated by the linear CM mode, because the current flowing to the floor in the linear CM mode is strong, the current excited in the floor is large. The floor has a significant influence on the directional pattern generated by the antenna. As a result, the directional pattern generated by the linear CM mode is not mainly toward the top of the electronic device (the direction in which the first radiator 310 is away from the floor, for example, the z direction).

[0010] Furthermore, in the satellite communication frequency band, the efficiency (e.g., radiation efficiency) of antennas resonating in the linear DM mode can meet satellite communication requirements. For example, when the first radiator extends in a straight line, under the action of unidirectional current, both conductor loss and dielectric loss are low, resulting in high efficiency (e.g., radiation efficiency) of the first antenna. However, due to the reverse current flow in the linear CM mode, losses are high, and antennas resonating in this mode have poor efficiency (e.g., radiation efficiency).

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

[0012] According to an embodiment of the present application, the first tuning circuit can be used to switch the resonant point 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 combination 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 and connected between the first connection point and the floor through the first switch.

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

[0015] In combination with the first aspect, in certain implementations of the first aspect, based on the coupling of the first connection point with the first switch branch, the first radiator is used to generate a first resonance; based on the coupling of the first connection point with the second switch branch, the first radiator is used to generate a second resonance; 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 an embodiment of the present application, when the first connection point is coupled to the first switch branch or the second switch branch through the first switch, the resonance frequency band generated by the first radiator may include the same satellite communication frequency band.

[0017] In combination with the first aspect, in certain 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 floor at the first grounding point; based on the coupling of the first connection point with the first switch branch, the first radiator is also used to generate a third resonance, and the resonance point frequency of the first resonance and the resonance point frequency of the third resonance have a first frequency difference; based on the coupling of the first connection point with the second switch branch, the first radiator is also used to generate a fourth resonance, and the resonance point frequency of the second resonance and the resonance point frequency of the fourth resonance have a second frequency difference, 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 the present application, when the difference between the first frequency difference and the second frequency difference is within the above 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 floor on the first side of the virtual axis and the current on the floor on the second side of the virtual axis is greater, thereby increasing the difference between the first radiation pattern and the second radiation pattern (for example, the angle between the maximum radiation directions increases), which can further widen the width of the radiation beam of the first antenna. The first antenna has a wider beamwidth, which enables the first antenna to have good communication characteristics over a wider range of angles (angles relative to the top direction).

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

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

[0021] According to an embodiment of the present 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 feed point and the second feed point is shorter, which can reduce losses caused by line transmission and improve the radiation characteristics of the antenna.

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

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

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

[0026] According to an embodiment of the present application, the first ground point can be located near the center of the first radiator to better excite the first radiator to generate a linear CM mode and a linear DM mode. Furthermore, when the first ground point is located near the center of the first radiator, it is easier to adjust the frequency difference between the resonances generated by the linear CM mode and the linear DM mode, thereby improving the radiation characteristics of the first antenna.

[0027] In combination with the first aspect, in certain 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, and the first element is coupled and connected between the second connection point and the third connection point, wherein the first frame has a first insulating gap at the first position, and the first frame is coupled to the floor at the second position, or the first frame is coupled to the floor at the first position, and the first frame has a second insulating gap at the second position.

[0028] According to an embodiment of the present application, the first radiator has a structure with one end being a grounded end and the other end being an open end. In addition, the third insulating gap of the first radiator can be regarded as an equivalent capacitor (for example, a distributed capacitor) provided on the first radiator, and the equivalent capacitor can enable the first radiator to form a metamaterial (meta) structure. The first radiator having the metamaterial structure can increase the radiation aperture, and the electric field is more dispersed after having the fifth insulating gap. In one embodiment, the dielectric loss near the first radiator forming the metamaterial structure is reduced, thereby effectively improving the radiation characteristics of the first antenna (for example, system efficiency and radiation efficiency).

[0029] Furthermore, by coupling the first element connected between the first connection point and the second connection point, the equivalent capacitance of the fifth insulating gap can be adjusted, thereby adjusting the radiation characteristics of the first antenna (eg, the resonance point frequency of the first resonance generated by the first radiator).

[0030] In combination with the first aspect, in certain 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.

[0034] According to an embodiment of the present 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 an equivalent capacitor (e.g., a distributed capacitor) provided on the second radiator, which can form a metamaterial structure on the second radiator.

[0035] In combination with the first aspect, in certain 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 combination with the first aspect, in certain 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 the present application, the resonance generated by the second radiator is generated by a linear DM mode. The directional pattern generated by the linear DM mode does not have a strong current flowing into the floor. Therefore, the current excited in the floor is small. The influence of the floor on the directional pattern generated by the linear DM mode is similar to that of a reflector. As a result, the directional pattern generated by the linear DM mode is mainly oriented toward the top of the electronic device (the direction in which the first radiator is away from the floor, for example, the z-direction). In contrast, the directional pattern generated by the linear CM mode, because the current flowing into the floor in the linear CM mode is strong, the current excited in the floor is large. The floor has a significant influence on the directional pattern generated by the antenna. As a result, the directional pattern generated by the linear CM mode is not mainly oriented toward the top of the electronic device (the direction in which the first radiator 310 is away from the floor, for example, the z-direction).

[0177] The following explains the terms that may appear in the embodiments of the present application.

[0178] It should be understood that the term "and / or" as used herein is simply a term used to describe the existence of three possible relationships between related objects. For example, "A and / or B" can represent the existence of A alone, the existence of both A and B, and the existence of B alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0179] When used in this application, "within the range of...", unless it is specifically stated that the end value is not included, it is assumed that both end values ​​of the range are included. For example, in the range of 1 to 5, the two values ​​1 and 5 are included.

[0180] Coupling: can be understood as direct coupling and / or indirect coupling, and "coupling connection" can be understood as direct coupling connection and / or indirect coupling connection. Direct coupling can also be referred to as "electrical connection", which is understood as the physical contact and electrical conduction between components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit signals; "indirect coupling" can be understood as two conductors being electrically connected in an airless / non-contact manner. In one embodiment, indirect coupling can also be referred to as capacitive coupling, for example, signal transmission is achieved by forming an equivalent capacitance through coupling between the gap between two conductive parts.

[0181] Component / device: includes at least one of lumped component / device and distributed component / device.

[0182] Lumped components / devices: A collective term for all components whose size is significantly smaller than the wavelength of the circuit's operating frequency. For signals, the component's characteristics remain constant at all times, independent of frequency. Lumped components / devices can include lumped capacitors, lumped inductors, and other components.

[0183] Distributed components / devices: Unlike lumped components, when a signal passes through a component, the characteristics of each point within the component will vary due to changes in the signal. Therefore, the component as a whole cannot be considered a single entity with fixed characteristics. Instead, it should be called a distributed component. Distributed components / devices can include distributed capacitance, distributed inductance, etc.

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

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

[0186] Radiator: A device in an antenna used to receive / send electromagnetic wave radiation. In some cases, the narrow meaning of "antenna" is the radiator, which converts the guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, used to radiate and receive radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator via the feeder line, where it is converted into a certain polarized electromagnetic wave energy and radiated in the desired direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space into modulated high-frequency current energy and transmits it to the receiver input via the feeder line.

[0187] The radiator may include a conductor with a specific shape and size, such as a linear or sheet shape, etc., and the present application does not limit the specific shape. In one embodiment, the linear radiator can be simply referred to as a linear antenna. In one embodiment, the linear radiator can be implemented by a conductive frame, and can also be called a frame antenna. In one embodiment, the linear radiator can be implemented by a bracket conductor, and can also be called a bracket antenna. In one embodiment, the wire diameter (for example, including thickness and width) of the linear radiator, or the radiator of the linear antenna is much smaller than the wavelength (for example, the wavelength of the medium) (for example, less than 1 / 16 of the wavelength), and the length can be comparable to the wavelength (for example, the wavelength of the medium) (for example, the length is about 1 / 8 of the wavelength, or 1 / 8 to 1 / 4, or 1 / 4 to 1 / 2, or longer). The main forms of linear antennas include dipole antennas, half-wave oscillator antennas, monopole antennas, loop antennas, and inverted F antennas (also known as IFA, Inverted F Antenna). For example, for a dipole antenna, each dipole antenna typically includes two radiating branches, and each branch is fed by a feeding portion from the feeding end of the radiating branch. For example, an inverted-F antenna (IFA) can be considered to be obtained by adding a ground path to a monopole antenna. The IFA antenna has a feeding point and a grounding point, and is called an inverted-F antenna because its side view is an inverted-F shape. 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 by a planar conductor (such as a conductive sheet or a 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, annular, etc., and the present application does not limit the specific shape. The structure of a microstrip antenna generally consists of a dielectric substrate, a radiator, and a floor, wherein the dielectric substrate is arranged between the radiator and the floor.

[0188] The radiator may also include a slot or slot formed in a conductor, for example, a closed or semi-closed slot or slot formed in a grounded conductor surface. In one embodiment, a slotted or slotted radiator may be referred to as a slot antenna or slot antenna. In one embodiment, the radial dimension (e.g., including the width) of the slot or slot of the slot antenna / slot antenna is much smaller than the wavelength (e.g., the dielectric wavelength) (e.g., less than 1 / 16 of the wavelength), and the length dimension may be comparable to the wavelength (e.g., the dielectric wavelength) (e.g., the length is 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 slot may be referred to as a closed slot antenna. In one embodiment, a radiator with a semi-closed slot or slot (e.g., a closed slot or slot with an additional opening) may be referred to as an open slot antenna. In some embodiments, the slot is elongated. In some embodiments, the slot is approximately half a wavelength (e.g., the dielectric wavelength). In some embodiments, the slot is approximately an integer multiple of the wavelength (e.g., one wavelength). In some embodiments, the slot can be fed with a transmission line spanning one or both sides, thereby exciting a radio frequency electromagnetic field in the slot and radiating electromagnetic waves into space. In one embodiment, the radiator of a slot antenna or slot antenna can be implemented as a conductive frame with both ends grounded, also known as a frame antenna. In this embodiment, the slot antenna or slot antenna can be considered to include a linear radiator spaced from the floor and grounded at both ends, thereby forming a closed or semi-enclosed slot or slot. In one embodiment, the radiator of a slot antenna or slot antenna can be implemented as a bracket conductor with both ends grounded, also known as a bracket antenna.

[0189] The feed circuit is a circuit for receiving and / or transmitting radio frequency signals. The feed circuit may include a transceiver / machine (transceiver) and a radio frequency front end circuit (RF front end). In some cases, the "feed circuit" is understood in a narrow sense as a radio frequency chip (RFIC, Radio Frequency Integrated Circuit), and the RFIC can be considered to include a radio frequency front end circuit (or radio frequency front end chip) and a transceiver. The feed circuit has the function of converting radio waves (for example, radio frequency signals) and signals (for example, digital signals). Generally, it is considered to be the radio frequency part.

[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 and test the characteristics of the RF front-end circuit or antenna radiator through the cable. The RF front-end circuit can be considered as the circuit portion coupled between the test socket and the transceiver.

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

[0192] It should be understood that any two feeding circuits in the first / second / ...Nth feeding circuits in the present application may include the same transceiver, for example, a transmitting channel in a transceiver serves as the first feeding circuit and a receiving channel serves as the second feeding circuit, or, for example, the first receiving channel in a transceiver serves as the first feeding circuit and the second receiving channel serves as the second feeding circuit; any two feeding circuits in the first / second / ...Nth feeding circuits in the present application may also include the same RF front-end circuit, for example, processing signals through a tuning circuit or amplifier in an RF front-end circuit.

[0193] It should also be understood that two feeding circuits in the first / second / ...Nth feeding circuit in the present application usually correspond to two radio frequency test sockets in the 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 socket 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 element, and the tuning circuit may be an element used to switch the coupling connection of the radiator. The matching circuit performs impedance matching and / or frequency tuning functions. Generally, it is considered to be part of the antenna.

[0195] The grounding structure / feeding structure may include a connector, such as a metal spring, through which the radiator is coupled to the floor / feeding structure is coupled to the feeding circuit. In some embodiments, the feeding structure may include a transmission line / feeding line, and the grounding structure may include a grounding wire.

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

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

[0198] In some embodiments, the "closed end" can also be understood from the perspective of current distribution. The closed end or the grounded end can be understood as a point with larger current on the radiator, or as a point with smaller electric field on the radiator. In one embodiment, the current distribution characteristics of larger current / smaller electric field can be maintained by coupling electronic devices (for example, capacitors, inductors, etc.) through the closed end. In one embodiment, the current distribution characteristics of larger current / smaller electric field can be maintained by opening a gap at or near the closed end (for example, a gap filled with insulating material).

[0199] In some embodiments, the understanding of "open end" can also be viewed from the perspective of current distribution. The open end or floating end can be understood as a point with low current on the radiator, or as a point with high electric field on the radiator. In one embodiment, coupling electronic devices (for example, capacitors, inductors, etc.) through the open end can maintain the current distribution characteristics of the low current point / high electric field point.

[0200] It should be understood that coupling the radiator end at a gap (from the perspective of the radiator structure, it is similar to the radiator at the opening of the open end or the suspended end) with electronic devices (for example, capacitors, inductors, etc.) can make the radiator end a point with larger current / smaller 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 “suspended radiator” mentioned in the embodiments of the present application means that the radiator is not directly connected to the feed line / feed branch and / or the ground line / ground branch, but is fed and / or grounded through indirect coupling.

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

[0203] The current same direction / reverse direction mentioned in the embodiments of the present application should be understood as the direction of the main current on the conductor on the same side is the same direction / reverse direction. For example, when stimulating a unidirectional distributed current on a conductor that is bent or ring-shaped (for example, the current path is also bent or ring-shaped), it should be understood that, for example, the main currents stimulated on the conductors on both sides of the ring conductor (for example, a conductor surrounding a gap, on the conductors on both sides of the gap) are opposite in direction, which still falls within the definition of the unidirectional distributed current in the embodiments of the present application. In one embodiment, the current same direction on a conductor can refer to the current on the conductor having no reversal point. In one embodiment, the current reverse on a conductor can refer to the current on the conductor having at least one reversal point. In one embodiment, the current same direction on two conductors can refer to the current on both conductors having no reversal point and flowing in the same direction. In one embodiment, the current reverse on two conductors can refer to the current on both conductors having no reversal point and flowing in opposite directions. The current same direction / reversal 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 in which resonance occurs. The resonant frequency can be the frequency range in which the return loss characteristic is less than -5dB. The strongest resonance point can be called the resonance point, and the frequency corresponding to the resonance point is the center frequency point 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, the antenna / radiator mentioned in this application produces a "first / second... resonance", where 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 the specific design, and each antenna mode can generate a corresponding fundamental mode resonance.

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

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

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

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

[0209] Where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0210] Wavelength: Or operating wavelength, this 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, if the center frequency of the B1 uplink frequency band (resonant frequency 1920MHz to 1980MHz) is 1955MHz, the operating wavelength can be the wavelength calculated using 1955MHz. "Operating wavelength" is not limited to the center frequency; it can also refer to the wavelength corresponding to a non-center frequency of the resonant frequency or operating frequency band.

[0211] It should be understood that the wavelength of the radiation signal in air can be calculated as follows: (wavelength in air, or wavelength in vacuum) = speed of light / frequency, where frequency is the frequency of the radiation signal (MHz), and the speed of light can be taken as 3×10 8 m / s. The wavelength of the radiation signal in the medium can be calculated as follows: Wherein, ε is the relative dielectric constant of the medium. The wavelength in the embodiments of the present application generally refers to the dielectric wavelength, which can be the dielectric wavelength corresponding to the center frequency of the resonant frequency, or the dielectric wavelength corresponding to the center frequency of the working frequency band supported by the antenna. For example, assuming that the center frequency of the B1 uplink frequency band (resonant frequency is 1920MHz to 1980MHz) is 1955MHz, the wavelength can be the dielectric wavelength calculated using the frequency of 1955MHz. Not limited to the center frequency, "dielectric wavelength" can also refer to the dielectric wavelength corresponding to the non-center frequency of the resonant frequency or the working frequency band. For ease of understanding, the dielectric wavelength mentioned in the embodiments of the present application can be simply calculated by the relative dielectric constant of the medium filled on one or more sides of the radiator.

[0212] Antenna system efficiency (total efficiency): refers to the ratio of input power to output power at the antenna port.

[0213] Antenna radiation efficiency refers to the ratio of the power radiated by an antenna into space (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 minus power loss; power loss primarily includes return loss and metal ohmic loss and / or dielectric loss. Radiation efficiency measures the antenna's radiation capability, and both metal loss and dielectric loss contribute to it.

[0214] Those skilled in the art will understand that efficiency is generally expressed as a percentage, which has a corresponding conversion relationship with dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna.

[0215] Antenna return loss: This can be understood as the ratio of the signal power reflected back to the antenna port by the antenna circuit to the antenna port's transmitted power. The smaller the reflected signal, the larger the signal radiated from the antenna into space, and the greater the antenna's radiation efficiency. The larger the reflected signal, the smaller the signal radiated from the antenna into space, and the lower the antenna's radiation efficiency.

[0216] Antenna return loss can be expressed using the S11 parameter, a type of S parameter. S11 represents the reflection coefficient and characterizes the antenna's transmission efficiency. The S11 parameter is typically negative. A smaller S11 parameter indicates lower antenna return loss and less energy reflected back from the antenna itself, meaning more energy actually enters the antenna and higher system efficiency. A larger S11 parameter indicates greater antenna return loss and lower system efficiency.

[0217] It should be noted that in engineering, an S11 value of -6dB is generally used as a standard. When the S11 value of an antenna is less than -6dB, it can be considered that the antenna can work normally, or the antenna can be considered to have good transmission efficiency.

[0218] Antenna pattern: Also known as radiation pattern. It is a graph showing how the relative field strength (normalized modulus) of the antenna's radiation field changes with direction at a certain distance from the antenna (far field). It is usually represented by two mutually perpendicular plane patterns passing through the antenna's direction of maximum radiation.

[0219] Antenna patterns typically have multiple radiation beams. The beam with the strongest radiation intensity is called the main lobe, while the remaining beams are called side lobes. Among the side lobes, those in the opposite direction of the main lobe are also called back lobes.

[0220] Beamwidth: This refers to the range of angles within a first range relative to the top of the electronic device (e.g., the y-direction) where the gain of the antenna's pattern is greater than or equal to a threshold. This first angle is the beamwidth. When the first angle is large, for example, greater than or equal to 60°, the antenna is considered to have a wide beam and exhibit good radiation characteristics within this angle range.

[0221] Directivity: Also known as the directivity of an antenna, it refers to the ratio of the maximum power density to the average power density in the antenna pattern at a certain distance from the antenna (far field). It is a dimensionless ratio greater than or equal to 1. It can be used to indicate the energy radiation characteristics of an antenna. A larger directivity indicates that the antenna radiates more energy in a certain direction and the energy radiation is more concentrated.

[0222] Antenna Gain: This is used to measure how well an antenna radiates input power. Generally, the narrower the main lobe of an antenna pattern and the smaller the side lobes, the higher the antenna gain.

[0223] Polarization direction of an antenna: At a given point in space, the electric field strength E (vector) is a function of time t. As time passes, the endpoints of the vector periodically trace a trajectory in space. If this trajectory is straight and perpendicular to the ground, it is called vertical polarization. If it is horizontal to the ground, it is called horizontal polarization. If this trajectory is elliptical or circular and rotates clockwise or to the right as viewed along the propagation direction, it is called right-hand circular polarization (RHCP). If it rotates counterclockwise or to the left as viewed along the propagation direction, it is called left-hand circular polarization (LHCP).

[0224] Ground (GND): can generally refer to at least a part of any grounding layer, grounding plate, or grounding metal layer in an electronic device (such as a mobile phone), or at least a part of any combination of any of the above grounding layers, grounding plates, or grounding components. "Ground / floor" can be used for grounding components in an electronic device, or in other words, can be used as a reference ground for components in an electronic device. Usually, large pieces of metal (for example, metal layers) in an electronic device can be used as "ground / floor". In one embodiment, the "ground / floor" can include any one or more of the following: the grounding layer of the circuit board of the electronic device, the grounding plate formed by the middle frame of the electronic device, the grounding metal layer formed by the metal film under the screen, the conductive grounding layer of the battery, the metal hinge of a foldable electronic device, the metal back cover of the electronic device (for example, when at least a part of the back cover is metal), and conductive parts or metal parts electrically connected to the above grounding layer / grounding plate / metal layer. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12-14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or an element separated and electrically isolated 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 routing layer, and the routing layer and the ground layer are electrically connected through vias. In one embodiment, components such as a display, a touch screen, input buttons, a transmitter, a processor, a memory, a battery, a charging circuit, a system on a chip (SoC), etc. can be mounted on or connected to the circuit board; or electrically connected to the routing layer and / or ground layer in the circuit board. For example, a radio frequency source is provided in the routing layer.

[0225] Any of the above-mentioned grounding layers, grounding plates, or grounding metal layers are made of a conductive material. In one embodiment, the conductive material can be any of the following: copper, aluminum, stainless steel, brass, and alloys thereof, 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 and tin-plated copper on an insulating substrate, cloth impregnated with graphite powder, a graphite-coated substrate, a copper-plated substrate, a brass-plated substrate, and an aluminum-plated substrate. Those skilled in the art will appreciate that the grounding layer / grounding plate / grounding metal layer can also be made of other conductive materials.

[0226] Grounding refers to coupling with the ground / floor via a grounding structure and / or grounding circuit. In one embodiment, grounding can be achieved through physical grounding, such as achieving physical grounding at a specific location on the frame through a portion of the middle frame's structural components (or referred to as a physical ground). In one embodiment, grounding can be achieved through device grounding, such as grounding through a capacitor, inductor, resistor, or other device connected in series or parallel (or referred to as a device ground).

[0227] The technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0228] As shown in FIG1 , 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, cover 13 may be a glass cover or may be replaced with a cover made of other materials, such as a PET (Polyethylene terephthalate) material.

[0229] The cover plate 13 may be disposed closely against the display module 15 , and may be mainly used to protect the display module 15 and prevent dust.

[0230] In one embodiment, the display module 15 may include a liquid crystal display panel (LCD), a light emitting diode (LED) display panel, or an organic light-emitting diode (OLED) display panel, etc., which is not limited in the embodiment of the present application.

[0231] The middle frame 19 mainly supports the entire device. FIG1 shows that the PCB 17 is arranged between the middle frame 19 and the back cover 21. It should be understood that in one embodiment, the PCB 17 can also be arranged between the middle frame 19 and the display module 15. This embodiment of the present application does not limit this. Among them, the printed circuit board PCB17 can use a flame-resistant material (FR-4) dielectric board, a Rogers dielectric board, a mixed dielectric board of Rogers and FR-4, and so on. Here, FR-4 is a code for a grade of flame-resistant material, and the Rogers dielectric board is a high-frequency board. Components such as radio frequency chips are carried on the PCB 17. In one embodiment, a metal layer can be provided on the printed circuit board PCB17. The metal layer can be used to ground the components carried on the printed circuit board PCB17, and can also be used to ground other components, such as bracket antennas, frame antennas, etc. The metal layer can be called a floor, a grounding plate, or a grounding layer. In one embodiment, the metal layer can be formed by etching metal on the surface of any layer of the dielectric board in the PCB 17. In one embodiment, the metal layer used for grounding can be provided on the side of the printed circuit board PCB 17 near the middle frame 19. In one embodiment, the edge of the printed circuit board PCB 17 can be considered the edge of its ground layer. In one embodiment, the metal middle frame 19 can also be used to ground the aforementioned components. The electronic device 100 may also have other floor / ground planes / ground layers, as previously described and will not be further described here.

[0232] Due to the compactness of electronic devices, a floor / grounding plate / grounding layer is typically provided within a 0-2mm internal space from the inner surface of the frame (for example, the printed circuit board, midframe, screen metal layer, battery, etc. can all be considered part of the floor). In one embodiment, a dielectric is filled between the frame and the floor, and the length and width of the rectangle enclosed by the inner surface contour of the dielectric filling can be simply considered the length and width of the floor. Alternatively, the length and width of the rectangle enclosed by the contour of all conductive parts within the frame can be considered the length and width of the floor.

[0233] The electronic device 100 may further include a battery (not shown). 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, and this is not limited in this embodiment of the present application. In some embodiments, the PCB 17 is divided into a main board and a sub-board, and the battery may be disposed between the main board and the sub-board. The main board may be disposed between the middle frame 19 and the upper edge of the battery, and the sub-board may be disposed between the middle frame 19 and the lower edge of the battery.

[0234] The electronic device 100 may further include a frame 11, which may be made of 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.

[0235] In one implementation, the frame 11, which primarily comprises a conductive material, can be referred to as a conductive frame or metal frame of the electronic device 100, and is suitable for use in industrial designs (ID) with a metallic appearance. In one implementation, the outer surface of the frame 11 is primarily made of a conductive material, such as a metal material, thereby creating the appearance of a metallic frame. In these implementations, the conductive portion of the frame 11, including the outer surface, can serve as an antenna radiator for the electronic device 100 and is generally referred to as a frame antenna.

[0236] In another implementation, the outer surface of the frame 11 is primarily composed of a non-conductive material, such as plastic, creating a non-metallic frame appearance suitable for non-metallic IDs. In one implementation, the inner surface of the frame 11 may include a conductive material, such as metal. In this implementation, the conductive portion of the inner surface of the frame 11 can serve as an antenna radiator for the electronic device 100. It should be understood that the radiator (or, in other words, the conductive material on the inner surface) disposed on the inner surface of the frame 11 can be positioned adjacent to the non-conductive material of the frame 11 to minimize the volume occupied by the radiator and to be closer to the exterior of the electronic device 100, achieving better signal transmission. This can also be referred to as a frame antenna. It should be noted that the antenna radiator being positioned adjacent to the non-conductive material of the frame 11 means that the antenna radiator can be positioned closely to the inner surface of the non-conductive material, embedded within the non-conductive material, or positioned close to the inner surface of the non-conductive material, for example, with a small gap between the antenna radiator and the inner surface of the non-conductive material. It should be understood that both the conductive and non-conductive materials can be considered part of the frame 11.

[0237] It should be understood that there may be insulating gaps on the frame 11, and the conductive parts of the frame between the insulating gaps and / or between the insulating gaps and the grounding points serve as radiators, thereby forming a frame antenna (it should be understood that the radiator of the frame antenna may also include the conductive parts of the frame between the grounding points). 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 non-metallic material (insulating material). In this case, the gap is visible on the exterior surface. When the outer surface of the frame 11 is a non-conductive material, the insulating gap can be understood as the end of the radiator on the inner surface of the frame 11 (for example, the end that is not electrically connected to other radiators or conductors), or as a gap formed between radiators on the inner surface of the frame 11. Non-metallic material (insulating material) may be provided in the gap, or non-metallic material may not be provided, for example, it may be filled with air. In this case, the gap is not visible on the exterior surface.

[0238] FIG1 and the subsequent embodiments illustrate an example in which the frame 11 of the electronic device 100 is a metal frame (conductive frame) and has a visible slit on the exterior surface (an insulating gap visible on the exterior surface). In this case, the metal frame serves as at least a portion of the antenna radiator. It should be understood that the same technical effects can be achieved when the frame 11 of the electronic device 100 is a non-metallic frame (with an invisible slit on the exterior surface). For the sake of brevity, these details will not be detailed here.

[0239] The middle frame 19 may include a border 11, and the middle frame 19 including the border 11 is an integral part that can support the electronic devices in the whole machine. The cover 13 and the back cover 21 are respectively covered along the upper and lower edges of the border to form a shell or housing (housing) of the electronic device. In one embodiment, the cover 13, the back cover 21, the border 11 and / or the middle frame 19 can be collectively referred to as the shell or housing of the electronic device 100. It should be understood that "shell or housing" can be used to refer to part or all of any one of the cover 13, the back cover 21, the border 11 or the middle frame 19, or to part or all of any combination of the cover 13, the back cover 21, the border 11 or the middle frame 19.

[0240] The frame 11 can at least partially serve as an antenna radiator to transmit and receive radio frequency signals. A gap can exist between this portion of the frame serving as the radiator and the rest of the middle frame 19 to ensure a good radiation environment for the antenna radiator. In one embodiment, the middle frame 19 can have an aperture in this portion of the frame serving as the radiator to facilitate antenna radiation.

[0241] Alternatively, the frame 11 may not be considered as part of the middle frame 19. In one embodiment, the frame 11 may be connected to the middle frame 19 and formed integrally. In another embodiment, the frame 11 may include a protrusion extending inward to be connected to the middle frame 19, for example, by means of a shrapnel, screws, welding, etc. The protrusion of the frame 11 can also be used to receive feed signals, so that at least a portion of the frame 11 serves as a radiator of the antenna to receive / transmit radio frequency signals. There may be a gap between this part of the frame that serves as the radiator and the middle frame 19, thereby ensuring that the antenna radiator has a good radiation environment, so that the antenna has a good signal transmission function.

[0242] The back cover 21 can be made of metal, non-conductive materials such as glass or plastic, or a combination of conductive and non-conductive materials. In one embodiment, the conductive back cover 21 can replace the middle frame 19 and integrate with the frame 11 to support the electronic components within the device.

[0243] In one embodiment, the middle frame 19 and / or the conductive parts in the back 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 middle frame.

[0244] The antenna of electronic device 100 may also be disposed within the housing, such as a bracket antenna or millimeter-wave antenna (not shown in FIG1 ). The clearance for the antenna disposed within the housing can be provided by a slot / opening in any of the middle frame, and / or the frame, and / or the back cover, and / or the display screen, or by a non-conductive gap / aperture formed between any of these. The antenna clearance ensures the antenna's radiation characteristics. It should be understood that the antenna clearance can be a non-conductive area formed by any conductive component within electronic device 100, through which the antenna radiates signals to the outside world. In one embodiment, antenna 40 may 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). In one embodiment, the antenna may also be a transparent structure embedded within the screen of electronic device 100, such that the antenna is a transparent antenna unit embedded within the screen of electronic device 100.

[0245] Figure 2 is a schematic diagram of the structure of a foldable electronic device 100 provided in an embodiment of the present application. 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 functionality. The embodiment shown in Figure 2 is described using a foldable mobile phone as an example.

[0246] It should be understood that FIG1 only shows an electronic device 100 including one shell (for example, the above-mentioned middle frame 19 ). In actual production or design, the electronic device 100 may also include multiple shells to form a foldable electronic device 100 .

[0247] Referring to Figure 2 , the foldable electronic device 100 may include a flexible display 110 (which may correspond to the display module 15 in Figure 1 ), a first frame 121 (which may correspond to the frame 11 in Figure 1 ), a first cover 122, a second frame 123 (which may correspond to the frame 11 in Figure 1 ), a second cover 124, and a hinge 125. In some embodiments, the first frame 121, the first cover 122, the second frame 123, and the second cover 124 may form a first housing 126 (which may correspond to the middle frame 19 in Figure 1 ) and a second housing 127 (which may correspond to the middle frame 19 in Figure 1 ) that support the flexible display 110. In other embodiments, at least one of the first cover 122 and the second cover 124 may include a display.

[0248] 2 is filled with a dot matrix pattern that schematically represents the flexible display screen 110. The flexible display screen 110 may be flexible and bendable, and may provide users with a new interaction method based on its bendability.

[0249] The flexible display screen 110 may include a first display portion 111 corresponding to the first housing 126 , a second display portion 112 corresponding to the second housing 127 , and a foldable display portion 113 corresponding to the hinge 125 . The foldable display portion 113 may be connected between the first display portion 111 and the second display portion 112 .

[0250] The first frame 121 can surround the outer periphery of the first cover 122, and at least a portion of the first frame 121 can also surround the outer periphery of the first display portion 111. The first display portion 111 can be arranged parallel to the first cover 122 and spaced apart from the first frame 121. The first display portion 111 and the first cover 122 can be located on either side of the first frame 121. The space between the first display portion 111 and the first cover 122 can be used to accommodate components of the foldable electronic device 100, such as antennas and circuit board components.

[0251] The second frame 123 can surround the outer periphery of the second cover 124, and at least a portion of the second frame 123 can also surround the outer periphery of the second display portion 112. The second display portion 112 can be arranged parallel to the second cover 124 and spaced apart from the second frame 123. The second display portion 112 and the second cover 124 can be located on either side of the second frame 123. The space between the second display portion 112 and the second cover 124 can be used to accommodate components of the foldable electronic device 100, such as antennas and circuit board components.

[0252] In one embodiment provided herein, the cover and the frame may be two parts of the housing of the foldable electronic device 100. The cover and the frame may be connected, and the form of the connection may not be an assembly method such as snap-on, gluing, welding, riveting, or clearance fit. The connection between the cover and the frame is usually difficult to separate. In another embodiment provided herein, the cover and the frame may be two different components. By assembling the cover and the frame together, the housing of the foldable electronic device 100 can be formed.

[0253] The hinge 125 can be connected between the first housing 126 and the second housing 127. The hinge 125 can move the first housing 126 and the second housing 127 closer to or farther from each other. Accordingly, the first display portion 111 of the flexible display 110 and the second display portion 112 of the flexible display 110 can move closer to or farther from each other, allowing the flexible display 110 to be folded or unfolded.

[0254] In one example, the rotating shaft 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. The mutual movement of the first and second connecting components can drive the mutual movement of the first and second housings 126 and 127, thereby realizing the opening and closing function of the foldable electronic device 100.

[0255] The foldable electronic device 100 shown in FIG2 is currently in a possible unfolded state. In this unfolded state, the angle between the first housing 126 and the second housing 127 can be 180 degrees, or what can be called a flattened state. The flexible display 110 can be in the flattened state shown in FIG2.

[0256] The flexible display 110 being in a flattened state can be understood as the angle between the first display portion 111 corresponding to the first housing 126 and the second display portion 112 corresponding to the second housing 127 being 180 degrees. Due to certain errors that may exist in engineering implementation, the flexible display 110 can be considered to be in a flattened state when the angle between the first display portion 111 and the second display portion 112 is between 170 degrees and 190 degrees.

[0257] FIG3 illustrates a possible folded state of the foldable electronic device 100. FIG3 shows the foldable electronic device 100 in an outwardly folded state (the outwardly folded state may be referred to as the outwardly folded state). The outwardly folded state illustrated in FIG3 may be, for example, a left-right outwardly folded state or a top-bottom outwardly folded state. The following describes a possible folded state of the foldable electronic device 100 in conjunction with FIG2 and FIG3.

[0258] In the embodiments of the present application, the foldable electronic device 100 being in a folded state may mean that the foldable electronic device 100 is currently bent and the degree of bending of the foldable electronic device 100 has reached its maximum. In this case, the first cover 122 and the second cover 124 may be approximately parallel, spaced apart from each other, and disposed face to face, with the spacing between the first cover 122 and the second cover 124 being minimized. At least portions of the first housing 126 and the second housing 127 are contained within the space enclosed by the flexible display 110. The first display portion 111, the first housing 126, the second housing 127, and the second display portion 112 are sequentially stacked. Similarly, the first display portion 111 and the second display portion 112 may be approximately parallel, spaced apart from each other, with the spacing between the first cover 122 and the second cover 124 being smaller than the spacing between the first display portion 111 and the second display portion 112. In this case, the first display portion 111 and the second display portion 112 may be considered to be located on different planes.

[0259] 2 and 3 , when the foldable electronic device 100 is in the outward folded state, the first cover 122 and the second cover 124 can be brought into close proximity, and the first display portion 111 and the second display portion 112 can be brought into close proximity. The first display portion 111, the second display portion 112, and the foldable display portion 113 can form a housing area for accommodating the first cover 122, the second cover 124, and the hinge 125. In other words, the first cover 122, the second cover 124, and the hinge 125 can be accommodated in the space between the first display portion 111 and the second display portion 112.

[0260] 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 close to each other, and the first display portion 111 and the second display portion 112 can be 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 portion 111, the second display portion 112, and the foldable display portion 113. In other words, the first display portion 111, the second display portion 112, and the foldable display portion 113 can be accommodated in the space between the first cover 122 and the second cover 124.

[0261] 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, the foldable electronic device 100 occupies a relatively small space. When the foldable electronic device 100 is in the unfolded state, the foldable electronic device 100 can display a relatively large screen to increase the user's viewing area. It should be understood that the folded state includes a closed state, in which the foldable electronic device 100 occupies the smallest space; the unfolded state includes a flattened state, in which the foldable electronic device 100 occupies the largest space.

[0262] The foldable electronic device 100 may further include a third housing 128 and a hinge 129, as shown in FIG4 . The hinge 129 may be connected between the third housing 128 and the second housing 127. The third housing 128 and the second housing 127 may be moved closer to or further away from each other. As the number of foldable portions of the foldable electronic device 100 increases, the space occupied by the foldable electronic device 100 may be further reduced in the folded state while maintaining the same screen size in the unfolded state.

[0263] In the foldable electronic device 100 shown in Figure 4, since it has three foldable parts (first shell 126, second shell 127 and third shell 128), the foldable electronic device 100 has at least three forms: 1. unfolded state; 2. folded state; 3. partially unfolded state.

[0264] 1. As shown in FIG4 , a possible unfolded state of the foldable electronic device 100 is shown. In the unfolded state, the angle between the first housing 126 , the second housing 127 , and the third housing 128 may be approximately 180°. The flexible display 110 may be in the unfolded state.

[0265] 2. Figure 5 shows a possible folded state (tri-folded state) of the foldable electronic device 100. In the folded state, the first housing 126 and the second housing 127 rotate along the rotation axis 125, and the second housing 127 and the third housing 128 rotate along the rotation axis 129, thereby achieving the maximum degree of curvature of the foldable electronic device 100. In this state, the first housing 126, the second housing 127, and the third housing 128 can be considered to be located on different planes.

[0266] It should be understood that for the sake of simplicity, in the structure shown in FIG5 , the folded state of the foldable electronic device 100 is an S-fold (the side of the foldable electronic device 100 is S-shaped, and the second shell 127 is located between the first shell 126 and the third shell 128). In one embodiment, the folded state of the foldable electronic device 100 can also be a G-fold (the side of the foldable electronic device 100 is G-shaped, and the third shell 128 is located between the first shell 126 and the second shell 127). The embodiment of the present application does not limit the folding state of the foldable electronic device 100.

[0267] 3. As shown in FIG6 , a possible partially unfolded state (two-folded state) of the foldable electronic device 100 is shown. In the partially unfolded state, the angle between the first shell 126 and the second shell 127 can be approximately 180°, and the second shell 127 and the third shell 128 rotate along the rotation axis 129, so that the third shell 128 approaches the second shell 127. In this case, the first shell 126 and the second shell 127 are considered to be located on the same plane, and the second shell 127 and the third shell 128 can be considered to be located on different planes. In another possible partially unfolded state, the angle between the third shell 128 and the second shell 127 can be approximately 180°, and the first shell 126 and the second shell 127 rotate along the rotation axis 125, so that the first shell 126 approaches the second shell 127.

[0268] FIG1 and FIG2 only schematically illustrate some components included in the electronic device 100 and the foldable electronic device 100. The actual shapes, actual sizes, and actual structures of these components are not limited by the above drawings.

[0269] It should be understood that in the embodiments of the present application, the surface where the display screen of the electronic device is located can be considered as the front surface, the surface where the back cover is located can be considered as the back surface, and the surface where the frame is located can be considered as the side surface.

[0270] It should be understood that in the embodiments of the present application, when a user holds an electronic device (usually vertically and facing the screen), the electronic device is located at a position having a top, a bottom, a left side, and a right side. It should be understood that in the embodiments of the present application, when a user holds an electronic device (usually vertically and facing the screen), the electronic device is located at a position having a top, a bottom, a left side, and a right side.

[0271] First, the two antenna modes involved in this application are introduced by Figures 7 and 8. Figure 7 is a schematic diagram of the structure of the common mode mode of an antenna provided by this application and the corresponding current and electric field distribution. Figure 8 is a schematic diagram of the structure of the differential mode mode of another antenna provided by this application and the corresponding current and electric field distribution. The antenna radiator in Figures 7 and 8 is open at both ends, and its common mode mode and differential mode mode can be referred to as a line common mode mode and a line differential mode mode, respectively.

[0272] It should be understood that the "common mode" or "CM mode" in this application includes the line common mode mode and the slot common mode mode, and the "differential mode mode" or "DM mode" in this application includes the line differential mode mode and the slot differential mode mode, which can be specifically determined according to the structure of the antenna.

[0273] 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 refers to the slot common mode and slot differential mode generated on the same radiator, which can be specifically determined according to the structure of the antenna.

[0274] 1. Wire common mode (CM) mode

[0275] (a) in Figure 7 shows that the radiator of the antenna 40 is open at both ends and is connected to a feeding circuit (not shown) at the middle position 41. In one embodiment, the feeding form of the antenna 40 adopts symmetrical feed. The feeding circuit can be connected to the middle position 41 of the antenna 40 through a feeding line 42. It should be understood that symmetrical feeding can be understood as one end of the feeding circuit being connected to the radiator and the other end being coupled to the floor to achieve grounding, wherein the connection point between the feeding circuit and the radiator (feeding point) is located at the center of the radiator. The center of the radiator can be, for example, the midpoint of the geometric structure, or the midpoint of the electrical length (or an area within a certain range near the above midpoint).

[0276] 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. For example, the connection between the feed line 42 and the antenna 40 covers the middle position 41 .

[0277] (b) in FIG7 shows the current and electric field distribution of the antenna 40. As shown in (b) in FIG7, the current is distributed in opposite directions on both sides of the middle position 41, for example, symmetrically; the electric field is distributed in the same direction on both sides of the middle position 41. As shown in (b) in FIG7, the current at the feed line 42 is distributed in the same direction. Based on the same direction distribution of the current at the feed line 42, the feeding shown in (a) in FIG7 can be called line CM feeding. Based on the opposite distribution of the current on both sides of the connection between the radiator and the feed line 42, the antenna mode shown in (b) in FIG7 can be called a line CM mode (also referred to as a CM mode for short, for example, for a linear antenna, the CM mode refers to a line CM mode). The current and electric field shown in (b) in FIG7 can be respectively referred to as the current and electric field of the line CM mode.

[0278] The current is stronger at the center 41 of the antenna 40 (the highest current point is near the center 41 of the antenna 40) and weaker at both ends of the antenna 40, as shown in FIG7(b). The electric field is weaker at the center 41 of the antenna 40 and stronger at both ends of the antenna 40.

[0279] 2. Line differential mode (DM) mode

[0280] As shown in Figure 8(a), the left and right ends of the two radiators of antenna 50 are open, and a feed circuit is connected at a center position 51. In one embodiment, antenna 50 uses an anti-symmetrical feed. One end of the feed circuit is connected to one of the radiators via a feed line 52, and the other end of the feed circuit is connected to the other radiator via a feed line 52. Center position 51 can be the geometric center of antenna 50 or the gap formed between the radiators.

[0281] It should be understood that the "center-antisymmetric feeding" mentioned in this application can be understood as the positive and negative poles of the feed unit being connected to two connection points near the aforementioned midpoint of the radiator. In one embodiment, the signals output by the positive and negative poles of the feed unit have the same amplitude but opposite phases, for example, a phase difference of 180°±10°.

[0282] Figure 8(b) shows the current and electric field distribution of antenna 50. As shown in Figure 8(b), the current is distributed in the same direction on both sides of the center position 51 of antenna 50, for example, with an antisymmetric distribution; the electric field is distributed in opposite directions on both sides of the center position 51. As shown in Figure 8(b), the current at the feed line 52 is distributed in opposite directions. Based on the opposite current distribution at the feed line 52, the feeding shown in Figure 8(a) can be referred to as linear DM feeding. Based on the current being distributed in the same direction on both sides of the connection between the radiator and the feed line 52, the antenna mode shown in Figure 8(b) can be referred to as a linear DM mode (or simply a DM mode, for example, for a linear antenna, a DM mode refers to a linear DM mode). The current and electric field shown in Figure 8(b) can be referred to as the current and electric field of the linear DM mode, respectively. It should be understood that based on the current being distributed in the same direction on both sides of the connection between the radiator and the feed line 52, the antenna mode shown in Figure 8(b) can also be referred to as a half-antenna mode, a half-wavelength mode, or simply a half-mode.

[0283] In one embodiment, in the wire DM mode, or half mode, the current is stronger at the center 51 of the antenna 50 (the highest current point is near the center 51 of the antenna 50) and weaker at both ends of the antenna 50, as shown in FIG8(b). The electric field is weaker at the center 51 of the antenna 50 and stronger at both ends of the wire antenna 50.

[0284] It should be understood that the antenna radiator can be understood as a metal structural member that generates radiation, and the number of the radiator can be one, as shown in FIG7 , or two, as shown in FIG8 , which can be adjusted according to actual design or production needs. For example, for the line CM mode, two radiators can be used as shown in FIG8 , with the two ends of the two radiators arranged opposite to each other and separated by a gap. A symmetrical feeding method is adopted at the two ends close to each other, for example, the same feed source signal is fed to the two ends of the two radiators close to each other, and an effect similar to the antenna structure shown in FIG7 can also be obtained. Correspondingly, for the line DM mode, one radiator can be used as shown in FIG7 , with two feeding points set in the middle of the radiator and an anti-symmetrical feeding method is adopted. For example, if two symmetrical feeding points on the radiator are fed with signals with the same amplitude and opposite phases, an effect similar to the antenna structure shown in FIG8 can also be obtained.

[0285] 3. Line CM-DM mode

[0286] FIG7 and FIG8 respectively show that when both ends of the radiator are open, a line CM mode and a line DM mode are generated by adopting different feeding methods.

[0287] When the antenna uses asymmetric feeding (the feeding point is offset from the center of the radiator, including side or offset feeding), or the radiator's grounding point (where it couples with the floor) is asymmetric (the grounding point is offset from the center of the radiator), the antenna can simultaneously produce a first resonance and a second resonance, corresponding to the linear CM mode and the linear DM mode, respectively. For example, the first resonance corresponds to the linear CM mode, with the current and electric field distributions shown in Figure 7(b). The second resonance corresponds to the linear DM mode, with the current and electric field distributions shown in Figure 8(b).

[0288] FIG9 is a schematic diagram of a satellite communication usage scenario provided in an embodiment of the present application.

[0289] As shown in FIG9 , when a user performs satellite communication through an electronic device, it is necessary to point the area of ​​the electronic device's antenna with better radiation characteristics toward the satellite to achieve satellite alignment (establishing a communication connection with the satellite).

[0290] During satellite communications, if the relative position of the electronic device and the satellite changes (for example, a low-orbit satellite may move), and the user's grip on the device remains unchanged, the antenna's maximum radiation direction will deviate from the target radiation direction (for example, the top direction of the device, which can be understood as the direction from the bottom of the device to the top). In this case, the electronic device and the communication satellite cannot maintain a good alignment, resulting in poor communication quality or even dropped calls, which greatly affects the user's communication experience.

[0291] It should be understood that the target radiation direction of the antenna described in the embodiments of the present application can be understood as the direction of the communication satellite relative to the electronic device 100, and in the present embodiment of the present application can be understood as the top direction of the electronic device. When the maximum radiation direction of the directional pattern generated by the antenna is close to the target radiation direction, a good communication connection is easily established between the electronic device 100 and the communication satellite.

[0292] The present application provides an electronic device comprising a first antenna and a second antenna. The operating frequency band of the first antenna and the operating frequency band of the second antenna include a satellite communication frequency band. 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 using the first antenna and the second antenna simultaneously, thereby improving the user experience during satellite communication.

[0293] It should be understood that the antenna and its radiator described in the embodiments of the present application may have different communication functions in different usage scenarios of the electronic device. For example, in the embodiments of the present application, the electronic device performing communication under the first satellite system is used as an example for explanation. 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 a directional pattern suitable for communication with 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 functions of other systems. For example, they can be used as antenna radiators or parasitic branches in cellular systems, or as antenna radiators or parasitic branches in wireless network communication technology (WiFi).

[0294] FIG10 is a schematic diagram of an electronic device 100 provided in an embodiment of the present application.

[0295] As shown in FIG. 10 , the electronic device 100 includes a first antenna 301 and a second antenna 302 .

[0296] The first antenna 301 includes a first radiator 310 and a first feeding circuit 311. The first radiator 310 includes a first feeding point 312, and the first feeding circuit 311 is coupled to the first feeding point 312.

[0297] The second antenna 302 includes a second radiator 320 and a second feeding circuit 321. The second radiator 320 includes a second feeding point 322, and the second feeding circuit 321 is coupled to the second feeding point 322.

[0298] The operating frequency bands of the first antenna 301 and the second antenna 302 may both include at least a portion of frequency bands in a satellite communication system. The electronic device 100 may perform satellite communication via the first antenna 301 and / or the second antenna 302 .

[0299] 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 receiving calls, and data services (such as Internet access).

[0300] In one embodiment, the satellite communication frequency band may include part of the frequency band in the Tiantong satellite system, and may include the transmit frequency band (1980MHz-2010MHz) and the receive frequency band (2170MHz-2200MHz) in the Tiantong satellite system. In one embodiment, the satellite communication frequency band may include part of the frequency band in the Beidou satellite system, and may include the transmit frequency band (1610MHz-1626.5MHz) and the receive frequency band (2483.5MHz-2500MHz) in the Beidou satellite system. In one embodiment, the satellite communication frequency band may include part of the frequency band in the low-orbit satellite system, and may include the transmit frequency band (1668MHz-1675MHz) and the receive frequency band (1518MHz-1525MHz) in the low-orbit satellite system. Alternatively, it may also be applied to other satellite communication systems, and the embodiments of the present application are not limited thereto.

[0301] In one embodiment, when the first antenna 301 and / or the second antenna 302 operates in the Tiantong satellite system (the operating frequency band of the first antenna 301 and / or the second antenna 302 includes at least part of the frequency band 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 operates in the Beidou satellite system (the operating frequency band of the first antenna 301 and / or the second antenna 302 includes at least part of the frequency band in the Beidou satellite system), the electronic device 100 can send or receive short messages and pictures 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 operate in a low-orbit satellite system (the operating frequency band of the first antenna 301 and / or the second antenna 302 includes at least part of the frequency band in the low-orbit satellite system), the electronic device 100 can perform voice communication, send or receive short messages, pictures, and access the Internet through the first antenna 301 and / or the second antenna 302. The low-orbit satellite can also have some functions similar to those of a base station.

[0302] In one embodiment, the first feeding circuit 311 is used to transmit radio frequency signals in a satellite communication frequency band. In one embodiment, the second feeding circuit 321 is used to transmit radio frequency signals in a satellite communication frequency band.

[0303] In one embodiment, the satellite communication frequency band includes a first frequency band and a second frequency band. The first frequency band includes a transmit frequency band in at least one satellite communication frequency band, and the second frequency band includes a receive frequency band in at least one satellite communication frequency band. In one embodiment, the first feed circuit 311 is configured to transmit radio frequency signals in the first frequency band or the second frequency band. In one embodiment, the second feed circuit 321 is configured to transmit radio frequency signals in the first frequency band or the second frequency band.

[0304] It should be understood that in the embodiment of the present application, the feed circuit can be understood as an RF channel of the RF IC in the electronic device 100, which is used to generate an RF signal fed into the antenna, or for processing the RF signal received by the antenna. A matching circuit (for example, including at least one element) can 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 an RF signal in a first frequency band that is fed into the antenna.

[0305] 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 point frequency at which the first antenna 301 resonates, 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 either 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 a first frequency band within its operating frequency band through different operating modes; or so that the first antenna 301 can support a second frequency band within 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 ground end (for example, the grounding state includes an open circuit, a disconnected circuit, a semi-open circuit, or a semi-disconnected circuit state with respect to the floor), or switching the open state of the radiator at the open end (for example, the open state also includes an open circuit, a disconnected circuit, a semi-open circuit, or a semi-disconnected circuit state with respect to the floor).

[0306] In one embodiment, the second antenna 302 may include a second tuning circuit 323. The second tuning circuit 323 may be used to switch the resonant frequency of the second antenna 302, 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 may be used to switch the operating frequency band of the second antenna 302 to include either the first frequency band or the second frequency band. In one embodiment, the second tuning circuit 323 may be used to switch the operating mode of the second antenna 302, so that the second antenna 302 can support the first frequency band within its operating frequency band through different operating modes, or support the second frequency band within its operating frequency band through different operating modes.

[0307] In one embodiment, the first frequency band may include at least part of the frequency band within 1.5 GHz to 4.5 GHz. In one embodiment, the first antenna 301 or the second antenna 302 operates in the Tiantong satellite system, and the first frequency band may include the transmit frequency band therein (e.g., 1980 MHz-2010 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates in the Beidou satellite system, and the first frequency band may include the transmit frequency band therein (e.g., 1610 MHz-1626.5 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates in a low-orbit satellite system (e.g., StarNet), and the first frequency band may include the transmit frequency band therein (e.g., 1668 MHz-1675 MHz).

[0308] In one embodiment, the second frequency band may include at least part of the frequency band within 1.5 GHz to 4.5 GHz. In one embodiment, the first antenna 301 or the second antenna 302 operates in the Tiantong satellite system, and the second frequency band may include the receiving frequency band therein (for example, 2170 MHz-2200 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates in the Beidou satellite system, and the second frequency band may include the receiving frequency band therein (for example, 2483.5 MHz-2500 MHz). In one embodiment, the first antenna 301 or the second antenna 302 operates in a low-orbit satellite system (for example, StarNet), and the second frequency band may include the receiving frequency band therein (for example, 1518 MHz-1525 MHz).

[0309] It should be understood that when the electronic device 100 performs satellite communication, it can communicate with the communication satellite through an antenna within the electronic device 100. In this case, the antenna can be loaded with different elements in different time slots to adjust the resonant point frequency, so that the antenna can operate in the transmission frequency band and the reception frequency band of the satellite system in different time slots.

[0310] For the sake of simplicity, in the following embodiments of the present application, the antenna for satellite communication in the electronic device 100 operating in the first frequency band is used as an example for explanation. When the antenna operates in the second frequency band, the same understanding can also be applied, and no further details will be given.

[0311] In one embodiment, the first feeding point 312 on the first radiator 310 (or the second feeding point 322 on the second radiator 320) receives a first RF signal fed by the first feeding circuit 311 (or the second feeding circuit 321). The first RF signal corresponds to the transmission frequency band of the satellite system. Then, the first antenna 301 (or the second antenna 302) operates in the transmission frequency band of the satellite system to transmit signals to the communication satellite.

[0312] In one embodiment, the first feeding point 312 on the first radiator 310 (or the second feeding point 322 on the second radiator 320) receives a second RF signal sent by a communication satellite and transmits it to the first feeding circuit 311 (or the second feeding circuit 321). The second RF signal corresponds to the receiving frequency band of the satellite system, and the first antenna 301 (or the second antenna 302) operates in the receiving frequency band of the satellite system to receive signals from the communication satellite.

[0313] In one embodiment, at a first time / time period, the first feeding point 312 (or the second feeding point 322) feeds a first radio frequency signal, and the resonance frequency band generated by the first radiator 310 (or the second radiator 320) includes a first frequency band, and the first frequency band may include a transmission frequency band in at least one satellite communication frequency band.

[0314] 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 sent by a communication satellite, and the resonant frequency band generated by the first radiator 310 (or the second radiator 320) includes a second frequency band, which may include a receiving frequency band in at least one satellite communication frequency band.

[0315] The first directional pattern generated by the first antenna 301 is different from the second directional pattern generated by the second antenna 302 .

[0316] The difference between the first and second directional patterns can be understood as the difference between the maximum radiation direction of the first and second directional patterns. Alternatively, the difference between the first and second directional patterns can be understood as the difference between the zero point of the first and second directional patterns.

[0317] According to an embodiment of the present application, since the first directional pattern generated by the first antenna 301 and the second directional 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 of the communication satellite and the electronic device 100, so that the communication satellite is always located in an area where the first antenna 301 and / or the second antenna 302 have good radiation characteristics (for example, the maximum radiation direction of the directional pattern generated by the antenna at least partially overlaps with the target radiation direction), thereby maintaining the alignment state with the communication satellite, effectively improving the user experience.

[0318] In one embodiment, electronic device 100 performs satellite communications via a single antenna. During a first time period / time period, electronic device 100 performs satellite communications via first antenna 301. During a second time period / time period, electronic device 100 performs satellite communications via second antenna 302. For example, when a communications satellite is located in an area where first antenna 301 has good radiation characteristics, electronic device 100 communicates with the communications satellite via first antenna 301. For example, first antenna 301 transmits signals to the communications satellite in a first frequency band, and first antenna 301 receives signals from the communications satellite in a second frequency band.

[0319] In one embodiment, the electronic device 100 transmits signals to a communications satellite via a single antenna, or receives signals transmitted by a communications satellite via multiple antennas (e.g., a first antenna 301 and a second antenna 302). During a first time / time period, the electronic device 100 performs satellite communication in a first frequency band via the first antenna 301. During a second time / time period, the electronic device 100 performs satellite communication in a first frequency band via the second antenna 302. During a third time / time period, the electronic device 100 performs satellite communication in a second frequency band via the first antenna 301 and the second antenna 302. For example, when the communications satellite is always located in an area where the first antenna 301 has good radiation characteristics, the electronic device 100 transmits signals to the communications satellite via the first antenna 301 in the first frequency band. Alternatively, the first antenna 301 and the second antenna 302 receive signals transmitted by the communications satellite in a second frequency band.

[0320] In one embodiment, the electronic device 100 performs satellite communication using multiple antennas (e.g., the first antenna 301 and the second antenna 302). During a first time / time period, the electronic device 100 performs satellite communication using the first antenna 301 and the second antenna 302 in a first frequency band. During a second time / time period, the electronic device 100 performs satellite communication using the first antenna 301 and the second antenna 302 in a second frequency band. For example, the electronic device 100 uses multiple antennas (e.g., the first antenna 301 and the second antenna 302) to communicate with a communication satellite, including sending signals to the communication satellite using the multiple antennas (e.g., the first antenna 301 and the second antenna 302) in a first frequency band and receiving signals sent by the communication satellite using the multiple antennas (e.g., the first antenna 301 and the second antenna 302) in a second frequency band.

[0321] It should be understood that the electronic device 100 receives signals transmitted by the communication satellite in the second frequency band through multiple antennas (for example, the first antenna 301 and the second antenna 302) respectively, and the signals can be superimposed through algorithms and other means, thereby enhancing the communication quality between the electronic device 100 and the communication satellite.

[0322] 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. 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 comprise the same RF channel in the RF chip. In one embodiment, the circuit portion of the first feed circuit 311 between the RF channel and the first feed point 312 and the circuit portion of the second feed circuit 321 between the RF channel and the second feed point 322 include at least partially identical electronic components, such as a power amplifier (PA), a low noise amplifier (LNA), and the like.

[0323] In one embodiment, when the electronic device 100 performs satellite communications via multiple antennas, the electronic device 100 performs satellite communications simultaneously 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 RF channels in the RF chip. In one embodiment, the circuit portion of the first feed circuit 311 between the RF channel and the first feed point 312 and the circuit portion of the second feed circuit 321 between the RF channel and the second feed point 322 include at least partially different electronic components, such as PAs, LNAs, etc.

[0324] It should be understood that when the electronic device 100 performs satellite communications via multiple antennas, unlike an antenna array including multiple radiators (e.g., a phased array antenna), the first antenna 301 and the second antenna 302 each function as an independent antenna for satellite communications. 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 splitter and phase shifter circuit to ensure that the RF signals fed into the first antenna 301 and the second antenna 302 have different phase differences.

[0325] FIG11 is a schematic diagram of another electronic device 100 provided in an embodiment of the present application.

[0326] As shown in FIG. 11 , the electronic device 100 may include a first frame 210 .

[0327] The first frame 210 includes a first position 201, a second position 202, a third position 203, and a fourth position 204. At least a portion of the first frame 210 is spaced apart from the floor 300.

[0328] The first frame 210 has an insulating gap at a first position 201 or is coupled to the floor 300. The first frame 210 has an insulating gap at a second position 202 or is coupled to the floor 300. The first frame 210 has an insulating gap at a third position 203 or is coupled to the floor 300. The first frame 210 has an insulating gap at a fourth position 204 or is coupled to the floor 300.

[0329] The first frame 210 includes a first side 131 and a second side 132 that intersects the first side 131 at an angle. The length of the first side 131 is shorter 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. When the electronic device 100 is folded along the extension direction of the first side 131, it can be understood that the extension direction of the rotation axis is substantially parallel to the extension direction of the first side; when the electronic device 100 is folded along the extension direction of the second side 132, it can be understood that the extension direction of the rotation axis is substantially parallel to the extension direction of the second side.

[0330] It should be understood that the first side 131 can be the top side or the bottom side of the electronic device 100. For simplicity, the description will be given using the example where the first side 131 is the top side of the electronic device 100. The top side / bottom side of the electronic device 100 can be understood as the top / bottom side in normal use, for example, the top / bottom side of the desktop or user interface (GUI) in a mobile phone.

[0331] 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.

[0332] The electronic device 100 includes a first antenna 301 and a second antenna 302 .

[0333] First radiator 310 of first antenna 301 includes a conductive portion of first frame 210 between first position 201 and second position 202. At least a portion of first radiator 310 is spaced apart from floor 300. First antenna 301 also includes a first feeding circuit 311. First radiator 310 includes a first feeding point 312, and first feeding circuit 311 is coupled to first feeding point 312.

[0334] Second radiator 320 of second antenna 302 includes a conductive portion of first frame 210 between third position 203 and fourth position 204. At least a portion of second radiator 320 is spaced apart from floor 300. Second antenna 302 also includes a second feeding circuit 321. Second radiator 320 includes a second feeding point 322, and second feeding circuit 321 is coupled to second feeding point 322.

[0335] 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-mentioned embodiment. The electronic device 100 may perform satellite communication via the first antenna 301 and / or the second antenna 302.

[0336] In one embodiment, the minimum distance between the second radiator 320 and the first radiator 310 in the extension direction (eg, 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 .

[0337] It should be understood that the first radiator 310 and / or the second radiator 320 can be located in the upper half of the electronic device 100 (the area near the top), 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.

[0338] Because 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 good radiation in the top direction, thus having better radiation characteristics. The second antenna 302 can be used to improve the radiation performance of the electronic device 100 in the upper hemisphere. For example, the second antenna 302 can be used to enhance the radiation of the electronic device 100 in the top direction toward the second radiator 320, thereby enabling the electronic device 100 to have good communication characteristics over a wider range of angles from the top direction.

[0339] In the embodiment of the present application, the top direction can be understood as a direction perpendicular to the first side 131 and pointing from the inside of the electronic device 100 to the first side 131 .

[0340] The upper hemisphere region can be understood as a region with an angle less than or equal to 90° with the top direction, and can be understood as a region with the xoy plane facing the positive z direction in the coordinate system.

[0341] In one embodiment, the first radiator 310 may be used to generate a first resonance, and a resonance frequency band of the first resonance includes the first frequency band and / or the second frequency band.

[0342] 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 , as shown in FIG. 12 .

[0343] In one embodiment, the width of the first insulating gap is greater than or equal to 0.2 mm and less than or equal to 2 mm. It should be understood that, if the process allows, the width of the first insulating gap can be even smaller, or a conductive material can be disposed inside the first insulating gap and still achieve a similar antenna radiation effect. The width of the gap on the frame in the embodiment of the present application can be within the above range. For the sake of brevity, they are not detailed here. The "width of the insulating gap" can be simply understood as the dimension in the direction extending between two sections of conductive material (e.g., two radiators).

[0344] It should be understood that in the embodiment of the present application, only 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 is used as an example for description. In actual production or design, the arrangement may not be in this order. For example, the first position 201 may 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 may also form a similar structure (the radiator has a structure with one end being grounded and the other end being open). For the sake of brevity, similar structures will not be described one by one, and can be understood accordingly in the embodiment of the present application.

[0345] 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.

[0346] 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 .

[0347] It should be understood that the first radiator 310 is a structure with one end being a grounded end and the other end being an open end. In addition, the fifth insulating gap of the first radiator 310 can be regarded as an equivalent capacitor (for example, a distributed capacitor) provided on the first radiator 310, and the equivalent capacitor can enable the first radiator 310 to form a metamaterial (meta) structure. The first radiator 310 having the metamaterial structure can increase the radiation aperture, and the electric field is more dispersed after having the fifth insulating gap. In one embodiment, the dielectric loss near the first radiator 310 forming the metamaterial structure is reduced, thereby effectively improving the radiation characteristics of the first antenna 301 (for example, system efficiency and radiation efficiency).

[0348] Furthermore, by coupling the first element 331 connected 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 (for example, the resonance point frequency of the first resonance generated by the first radiator 310).

[0349] In one embodiment, the first radiator 310 has a structure with one end being a ground end and the other end being an open end. Since the area near the open end has a stronger magnetic field, the first tuning circuit shown in Figure 10 can be set close to the open end (second position 202) of the first radiator 310 so that the resonance point frequency generated by the first antenna 301 has a larger adjustment space.

[0350] In one embodiment, a length of the first frame between a connection point between the first tuning circuit and the first radiator 310 and the open end (the second position 202 ) is less than or equal to 10 mm.

[0351] It should be understood that when the radiators described in the embodiments of the present application have the same structure (the radiator has a structure in which one end is grounded and the other end is open), the settings of the tuning circuit can be understood accordingly and will not be described in detail.

[0352] In one embodiment, the electrical length of the first radiator 310 is greater than three-eighths of the first wavelength.

[0353] It should be understood that the first resonance generated by the first radiator 310 may correspond to a quarter-wavelength mode. The fifth insulating gap allows the electrical length of the first radiator 310 to be greater than three-eighths of the first wavelength, and the currents in the first radiator 310 flow in the same direction (e.g., not in opposite directions). The electrical length of the first radiator 310 increases from one-quarter of the first wavelength to greater than three-eighths of the first wavelength, while still operating in the quarter-wavelength mode.

[0354] In this case, the current density on first radiator 310 is dispersed, and the electric field density between first radiator 310 and floor 300 is weakened. This reduces the conductor loss and dielectric loss caused by first radiator 310 and the conductors and dielectrics disposed around first radiator 310, thereby improving the radiation characteristics of first antenna 301. First radiator 310 increases the radiation aperture, effectively improving the system efficiency and radiation efficiency of first antenna 301.

[0355] The first wavelength may be understood as the vacuum wavelength corresponding to the resonance point frequency of the first resonance generated by the first radiator 310 , or may be understood as the vacuum wavelength corresponding to the center frequency of the resonance frequency band formed by the first resonance generated by the first radiator 310 .

[0356] It should be understood that the above wavelengths are all vacuum wavelengths. Since there is a certain conversion relationship between medium wavelength and vacuum wavelength, the above vacuum wavelength can also be converted into medium wavelength.

[0357] In one embodiment, the length of the first radiator 310 between the first end (the ground end, the end at the second position 202) of the first radiator 310 and the fifth insulating gap is less than the length of the first radiator 310 between the second end (the open end, the end at the first position 201) of the first radiator 310 and the fifth insulating gap.

[0358] 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 part between the end of the end and the fifth insulating gap. For the sake of simplicity of discussion, it can be understood accordingly in the embodiments of the present application.

[0359] In one embodiment, the length of the first radiator 310 between the first end (the ground end, the end at the second position 202) of the first radiator 310 and the fifth insulating gap is less than three-fifths of the length of the first radiator 310 between the second end (the open end, the end at the first position 201) of the first radiator 310 and the fifth insulating gap.

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

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

[0362] It should be understood that the fifth insulating gap can be located in a region of the first radiator 310 where current is relatively high. The region of relatively high current should be understood as referring to the region corresponding to the first radiator 310 without the gap (e.g., operating in a quarter-wavelength mode). When the fifth insulating gap is included, the electric field strength of the first radiator 310 is weakened, thereby 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).

[0363] In one embodiment, the first element 331 may be a capacitor or an element equivalent to a capacitor.

[0364] In one embodiment, the equivalent capacitance value of the first element 331 can be less than or equal to a first threshold. The first threshold can 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.

[0365] In one embodiment, the first element 331 may be an inductor or an element equivalent to an inductor.

[0366] In one embodiment, the equivalent inductance of the first element 331 may be less than or equal to 5 nH.

[0367] It should be understood that by designing the equivalent capacitance value or equivalent inductance value of the first element 331 according to the frequency of the resonance point of different resonances, the current distribution on the first radiator 310 can be made more dispersed, the conductor loss can be reduced, and the radiation aperture of the first radiator 310 can be increased, thereby improving the radiation characteristics of the first antenna 301 (for example, system efficiency and radiation efficiency).

[0368] In one embodiment, the distance between the first connection point 341 and / or the second connection point 342 and the fifth insulation gap is less than or equal to 5 mm.

[0369] 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 in contact with the connection point and the conductors on both sides of the fifth insulating gap.

[0370] In one embodiment, the first radiator 310 may further include a third connection point 343 . The first antenna 301 may further include a second element 332 , which is coupled between the third connection point 343 and the floor 300 .

[0371] It should be understood that the electrical connection of the first radiator 310 to the floor 300 at the third connection point 343 via the second element 332 allows the current on the first radiator 310 to be shunted in the area near the third connection point 343 when the first radiator 310 generates the first resonance. This shunting in the area near the third connection point 343 disperses the current density on the first radiator 310. In one embodiment, the current distribution on the first radiator 310 is relatively more dispersed, thereby reducing the conductor loss of the first radiator 310. In one embodiment, the relatively more dispersed current distribution on the first radiator 310 can increase the radiation aperture of the first radiator 310. Due to the reduced conductor loss and increased radiation aperture of the first radiator 310, the radiation characteristics of the first antenna 301 (e.g., system efficiency and radiation efficiency) can be improved.

[0372] In one embodiment, the distance between the third connection point 343 and the first connection point 341 and / or the second connection point 342 (for example, the length of the first radiator 310 between the third connection point 343 and the first connection point 341 and / or the second connection point 342) is greater than or equal to 0 mm and less than or equal to 5 mm.

[0373] It should be understood that when the distance between the third connection point 343 and the first connection point 341 and / or the second connection point 342 is equal to 0 mm, the third connection point 343 coincides with the first connection point 341 and / or the second connection point 342 .

[0374] In the antennas described in the embodiments of the present application, when the operating mode of the antenna includes a quarter-wavelength mode (one end of the antenna is open and the other end is grounded), the antenna can have better radiation characteristics (for example, radiation efficiency) by using a structure similar to the first antenna 301 shown in Figure 12. For example, the second antenna 302 shown in Figure 12, the second antenna 302 shown in Figure 15, the first antenna 301 shown in Figure 20 (a), the second antenna 302 shown in Figure 20 (b), the first antenna 301 and the second antenna 302 shown in Figure 41, the first antenna 301 and the second antenna 302 shown in Figure 42, and so on. For the sake of brevity, they are not described one by one.

[0375] In one embodiment, the first frame 210 has a first insulating gap and a second insulating gap at the first position 201 and the second position 202 , respectively, as shown in FIG. 13 .

[0376] 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.

[0377] It should be understood that the first resonance generated by the first radiator 310 is caused by the linear DM mode described in the above embodiment. The directional pattern generated by the linear DM mode lacks a strong current flowing into the floor 300. Therefore, the current excited in the floor 300 is small, and the floor 300 has a similar effect on the directional pattern generated by the linear DM mode as a reflector. As a result, the directional pattern generated by the linear DM mode is primarily oriented toward the top of the electronic device 100 (the direction in which the first radiator 310 is away from the floor, e.g., the z-direction). In contrast, the directional pattern generated by the linear CM mode, due to the strong current flowing into the floor 300 in the linear CM mode, excites more current in the floor 300. Consequently, the floor 300 has a significant impact on the directional pattern generated by the antenna. Consequently, the directional pattern generated by the linear CM mode is not primarily oriented toward the top of the electronic device 100 (the direction in which the first radiator 310 is away from the floor, e.g., the z-direction).

[0378] Furthermore, in the satellite communication frequency band, the efficiency (e.g., radiation efficiency) of antennas resonating in the linear DM mode can meet satellite communication requirements. For example, when the first radiator 310 extends in a straight line, under the action of the same-direction current, the conductor loss and dielectric loss are both low, and the efficiency (e.g., radiation efficiency) of the first antenna 301 is high. However, due to the reverse current flow in the linear CM mode, the loss is large, and the efficiency (e.g., radiation efficiency) of antennas resonating in the linear CM mode is poor.

[0379] In one embodiment, because the area near the open end has a stronger magnetic field, the tuning circuit shown in FIG10 can be located near the open end (first position 201 or second position 202) on one side of the first radiator 310, thereby providing a greater adjustment range for 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 either side of the virtual axis of the first radiator 310.

[0380] 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 described in the embodiment of the present application can be understood as the two sides of the plane formed by the virtual axis and the thickness direction of the electronic device 100 (for example, the direction perpendicular to the display screen) (for example, the x-direction). At the same time, due to the requirements in the production design, the edge of the frame 11 facing the floor 300 (towards the inside of the electronic device 100) is not flat. Therefore, in the embodiment of the application, the virtual axis of the first radiator 310 can be understood as a straight line passing through the center of the first radiator 310 or the first grounding point 351 and perpendicular to the extension direction of the first radiator 310.

[0381] In one embodiment, the length of the frame between the connection point between the tuning circuit and the first radiator 310 and the open end (the first position 201 or the second position 202 ) is less than or equal to 10 mm.

[0382] It should be understood that when the radiators described in the embodiments of the present application have the same structure (both ends of the radiator are open ends), the relevant information of the tuning circuit can be understood accordingly and will not be described in detail.

[0383] In one embodiment, both ends of the first radiator 310 are open ends, and the first radiator 310 can operate in a half-wavelength mode. The electrical length of the first radiator 310 is half of the first wavelength.

[0384] In one embodiment, the first radiator 310 may further include a first grounding point 351 , as shown in FIG14 . The first radiator 310 is coupled to the floor 300 at the first grounding point 351 .

[0385] In one embodiment, the first grounding point 351 may be located in the central area of ​​the first radiator 310 . The central area may be understood as an area within 5 mm from the center of the first radiator 310 , and the lengths of the first radiators 310 on both sides of the center are the same.

[0386] It should be understood that by increasing the structural symmetry of the first antenna 301 , the first antenna 301 can have better communication performance.

[0387] In one embodiment, grounding can be achieved through a grounding member at the first grounding point 351. The width of the connection between the grounding member and the first frame 210 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0388] In one embodiment, when the grounding element includes at least a portion of the central area of ​​the first radiator 310 , it can be considered that the first grounding point 351 is located in the central area of ​​the first radiator 310 .

[0389] It should be understood that when the first radiator 310 is coupled to the floor 300 at the first ground point 351, the first radiator 310 can also generate a second resonance by the line CM mode, and the second resonance can be used to improve the radiation characteristics (for example, radiation efficiency) of the first antenna 301 in the first frequency band and / or the second frequency band.

[0390] In one embodiment, the length of the first radiator 310 between the first ground 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 ground point 351 and the second position 202 is greater than or equal to one quarter of the length of the first radiator 310 .

[0391] It should be understood that the first grounding point 351 can be located near the center of the first radiator 310 to better excite the first radiator 310 to generate the linear CM mode and the linear DM mode. Furthermore, when the first grounding point 351 is located near the center of the first radiator 310, it is easier to adjust the frequency difference between the resonances generated by the linear CM mode and the linear DM mode, thereby improving the radiation characteristics of the first antenna 301. For the sake of simplicity, all grounding points on the radiator described in the embodiments of this application can be understood accordingly and will not be detailed here.

[0392] In one embodiment, the resonance point frequency of the first resonance may be higher than the resonance point frequency of the second resonance. The ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance may be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance may be greater than or equal to 1.3 and less than or equal to 1.5.

[0393] In one embodiment, a frequency difference between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance may be greater than or equal to 100 MHz and less than or equal to 500 MHz.

[0394] It should be understood that in the first frequency band (or the second frequency band), the first antenna 301 can operate in a linear DM mode. The second resonance can be used to improve the radiation characteristics (eg, radiation efficiency) of the first antenna 301 in the resonance frequency band of the first resonance.

[0395] In one embodiment, the resonance point frequency of the first resonance may be higher than the resonance point frequency of the second resonance. The ratio between the resonance point frequency of the first resonance and the resonance point frequency of the second resonance may be less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band is greater than the resonance point frequency of the second resonance and less than the resonance point frequency of the first resonance.

[0396] It should be understood that in the first frequency band (or the second frequency band), the first antenna 301 can operate in a mixed mode of the linear CM mode and the linear DM mode, and radiation is jointly generated by the linear CM mode and the linear DM mode. The first antenna 301 has both partial radiation characteristics of the linear CM mode and partial radiation characteristics of the linear DM mode.

[0397] In one embodiment, the ratio of the first resonance frequency to the second resonance frequency is less than or equal to 1.2. In one embodiment, the frequency difference between the first resonance frequency and the second resonance frequency is less than or equal to 300 MHz.

[0398] In one embodiment, the first antenna 301 includes a first switch branch 361 , a second switch branch 362 , and a first switch 360 , as shown in FIG15 .

[0399] First radiator 310 includes a fourth connection point 344. A first switch branch 361 and a second switch branch 362 are coupled between fourth connection point 344 and floor 300 via first switch 360. In one embodiment, a first connection port of first switch 360 is coupled to first switch branch 361, and a second connection port of first switch 360 is coupled to second switch branch 362.

[0400] 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 panel 300 and the fourth connection point 344. In one embodiment, the first switch branch 361 and the second switch branch 362 are both connected in parallel between the floor panel 300 and the fourth connection point 344 through the first switch 360.

[0401] It should be understood that the switches described herein, for example, the "first switch," may include one or more switching devices; and the connection points described herein, for example, the "fourth connection point," may include one or more connection points. In one embodiment, the first switch branch 361 can be coupled between the floorboard 300 and the first radiator 310 via a switching device in the first switch and a connection point in the fourth connection points 344; the second switch branch 362 can be coupled between the floorboard 300 and the first radiator 310 via another switching device in the first switch and another connection point in the fourth connection points 344. In this embodiment, the switch is used only to switch between different switch branches coupled to the radiator / parasitic stub, and its specific location and form are not limited.

[0402] It should be understood that in the embodiment of the present application, the switch branch can be understood as a circuit between the switch and the connection point (for example, the fourth connection point 344) or the floor 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 is different.

[0403] In one embodiment, the first tuning circuit described in the above embodiment may include a first switch branch 361, a second switch branch 362, and a first switch 360. The first tuning circuit may also be used to adjust the current distribution on the first radiator 310 and the floor 300. In one embodiment, the first antenna 301 may further include a third switch branch, which may be used to adjust the resonant frequency of the resonance generated by the first antenna 301, allowing 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 via 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 via the first switch 360, the resonant frequency band of the resonance generated by the first radiator 310 includes the second frequency band.

[0404] In one embodiment, the switch branch may include one or more components, and the multiple components may be connected in series or in parallel to achieve different equivalent capacitance values ​​and / or equivalent inductance values ​​and / or equivalent resistance values. In one embodiment, the switch branch may also include a switch to switch the equivalent capacitance values ​​and / or equivalent inductance values ​​and / or equivalent resistance values ​​in different states of the switch branch.

[0405] 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, if the switch branch is in an open circuit state, when the switch common port is connected to the switch branch, the fourth connection point 344 is in an open circuit state (not coupled to the floor 300 through a device). Alternatively, if the switch branch is in a short circuit state, when the switch common port is connected to the switch branch, the fourth connection point 344 is in a short circuit state (electrically connected to the floor 300 and no other components are provided). For the sake of simplicity, in the electronic device 100 shown in Figure 14, only the first switch branch 361 including equivalent components and the second switch branch 362 including equivalent components are used as an example for explanation.

[0406] In one embodiment, the first feeding point 312 and the fourth connection point 344 are respectively located on two sides of the virtual axis of the first radiator 310. In this case, the first radiator 310 may include or not include the first grounding point 351.

[0407] 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 resonance frequency band generated by the first radiator 310 includes the first frequency band (or the second frequency band).

[0408] 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 resonance frequency band generated by the first radiator 310 includes the above-mentioned first frequency band (or second frequency band).

[0409] 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 resonance frequency band generated by the first radiator 310 may include the first frequency band.

[0410] In the embodiment of the present application (for example, the electronic device 100 shown in FIG14 ), the first antenna 301 is described as being in the same operating state. The same operating state can be understood as meaning that the operating frequency band of the first antenna 301 includes either the first frequency band or the second frequency band, and the first antenna 301 can communicate in the corresponding frequency band when the first switch 360 is coupled to the first switch branch 361 or the second switch branch 362.

[0411] In one embodiment, the first switch branch 361 and the second switch branch 362 can be used to adjust current distribution on the first radiator 310 and the floor 300 .

[0412] In one embodiment, the fourth connection point 344 is located on a first side of the virtual axis, and the first feeding point 312 is located on a second side of the virtual axis.

[0413] It should be understood that for the sake of simplicity of discussion, in the embodiments of the present application, only the fourth connection point 344 is located on the first side of the virtual axis and the first feed point 312 is located on the second side of the virtual axis as an example 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 feed point 312 may also be located on the first side of the virtual axis. Similarly, it can be understood accordingly.

[0414] 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 floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis.

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

[0416] 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 floor 300 on the first side of the virtual axis is less than the current on the floor 300 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 (for example, 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.

[0418] It should be understood that the current on the floor 300 described in the embodiment of the present 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 30 mm from the edge.

[0419] It should be understood that when the current (e.g., current intensity, current density) on the floor 300 on the first side of the virtual axis is greater than the current on the floor 300 on the second side of the virtual axis, the first directivity pattern generated by the first antenna 301 deflects toward the second side. When the current (e.g., current intensity, current density) on the floor 300 on the first side of the virtual axis is less than the current on the floor 300 on the second side of the virtual axis, the first directivity pattern generated by the first antenna 301 deflects toward the first side.

[0420] Therefore, by switching the switch branch coupled to the fourth connection point 344, the maximum radiation direction of the first directional pattern generated by the first antenna 301 can be deflected, so that the first antenna 301 can have good radiation characteristics in a larger area.

[0421] In one embodiment, the first switch branch 361 and the second switch branch 362 may both be capacitive, and the equivalent capacitance value of the first switch branch 361 and the equivalent capacitance value of the second switch branch 362 may both be less than or equal to 2 pF.

[0422] 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 smaller than the equivalent capacitance value of the second switch branch 362 .

[0423] When the second switch branch 362 is coupled 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 compared to when the first switch branch 361 is coupled to the fourth connection point 344 .

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

[0425] In one embodiment, the first switch branch 361 and the second switch branch 362 may both be inductive. The equivalent inductance of the first switch branch 361 and the equivalent inductance of the second switch branch 362 may both be greater than or equal to 5 nH and less than or equal to 100 nH.

[0426] 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 smaller than the equivalent inductance of the second switch branch 362 .

[0427] When the second switch branch 362 is coupled 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 compared to when the first switch branch 361 is coupled to the fourth connection point 344 .

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

[0429] In one embodiment, the first switch branch 361 may be capacitive, and the second switch branch 362 may be inductive.

[0430] When the second switch branch 362 is coupled 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 compared to when the first switch branch 361 is coupled to the fourth connection point 344 .

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

[0432] In one embodiment, when the first switch branch 361 is coupled to the fourth connection point 344, the frequency difference between the resonant point frequency of the first resonance generated by the first antenna 301 and the resonant point 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 point frequency of the first resonance generated by the first antenna 301 and the resonant point frequency of the second resonance is a second frequency difference. The first frequency difference is less than the second frequency difference.

[0433] In one embodiment, the first frequency difference is less than a first threshold value, and the second frequency difference is greater than the first threshold value. In one embodiment, the first threshold value is 300 MHz. In one embodiment, the first threshold value is 250 MHz. In one embodiment, the first threshold value is 200 MHz. In one embodiment, the first threshold value is 150 MHz.

[0434] It should be understood that the first switching branch 361 and the second switching branch 362 may also be used to adjust the frequency difference between the resonance point frequency of the resonance generated by the line CM mode and the resonance point frequency of the resonance generated by the line DM mode.

[0435] When the second switching branch 362 is coupled to the fourth connection point 344, the frequency difference between the resonance point frequency of the line CM mode and the resonance point frequency of the line DM mode increases compared to when the first switching branch 361 is coupled to the fourth connection point 344. This reduces the current in the floor panel 300 on the first side of the virtual axis, while increasing the current in the floor panel 300 on the second side of the virtual axis. When the first switching branch 361 is coupled to the fourth connection point 344, the frequency difference between the resonance point frequency of the line CM mode and the resonance point frequency of the line DM mode decreases compared to when the second switching branch 362 is coupled to the fourth connection point 344. This reduces the current in the floor panel 300 on the first side of the virtual axis, while decreasing the current in the floor panel 300 on the second side of the virtual axis.

[0436] 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.

[0437] It should be understood that when the difference between the first frequency difference and the second frequency difference is within the above range, and the fourth connection point 344 is coupled to the first switch branch 361 or the second switch branch 362, respectively, the difference between the current on the floor 300 on the first side of the virtual axis and the current on the floor 300 on the second side of the virtual axis is greater, thereby increasing the difference between the first radiation pattern and the second radiation pattern (for example, the angle between the maximum radiation directions increases), further widening the width of the radiation beam of the first antenna 301. The wide beamwidth of the first antenna 301 enables the first antenna 301 to have good communication characteristics over a wider range of angles (angles relative to the top direction).

[0438] In one embodiment, a length of the first frame 210 between the first feeding point 312 and the third position 203 is less than a length of the first frame 210 between the fourth connection point 344 and the third position 203 .

[0439] 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 losses caused by line transmission and improve the antenna's radiation characteristics.

[0440] Moreover, since the area near the feeding point usually has a strong current, when the first feeding point 312 can be located close to the side of the second antenna 302, it can be easier to enhance the current on the floor 300 on the second side of the virtual axis, so that the maximum radiation direction of the directional pattern generated by the first antenna 301 is deflected toward the side away from the second antenna 302, making the difference between the directional patterns of the first antenna 301 and the second antenna 302 larger, thereby enabling the electronic device 100 to have good communication characteristics within a wider angle range (angle with the top direction).

[0441] It should be understood that, in the antennas described in the embodiments of the present application, when the operating mode of the antenna includes a linear DM mode (both ends of the antenna are open), the switching between the first directional pattern and the second directional pattern can be achieved by a structure similar to the first antenna 301 shown in FIG15 . For example, the first antenna 301 and the second antenna 302 shown in FIG13 , the first antenna 301 and the second antenna 302 shown in FIG14 , the second antenna 302 shown in FIG20 (a) , the first antenna 301 shown in FIG20 (b) and (c) , the first antenna 301 shown in FIG25 , the first antenna 301 shown in FIG31 , the first antenna 301 and the second antenna 302 shown in FIG38 , the first antenna 301 and the second antenna 302 shown in FIG39 , and so on. For the sake of brevity, they are not described one by one.

[0442] In one embodiment, the second radiator 320 may be used to generate a third resonance, and the resonance frequency band of the third resonance includes the first frequency band and / or the second frequency band.

[0443] In one embodiment, the first frame 210 is coupled to the floor 300 at the third position 203 and has a fourth insulating gap at the fourth position 204 , as shown in FIG. 15 .

[0444] It should be understood that one end of the second radiator 320 is a ground 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.

[0445] When the second radiator 320 forms a structure similar to an inverted F-type antenna, the second feeding point 322 is close to the ground end, and the distance between the second feeding point 322 and the ground end (the length of the second radiator 320 between the second feeding point 322 and the third position 203) is less than or equal to half the length of the second radiator 320.

[0446] When the second radiator 320 forms 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 miniaturization of the second radiator 320. A capacitor is coupled between the second feed circuit 321 and the second feed point 322 to better excite the second radiator 320.

[0447] For the sake of simplicity, when a structure similar to an inverted F-type antenna or a left-hand antenna is formed, it can be understood accordingly in the application embodiments and will not be described in detail.

[0448] 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 a quarter of the second wavelength, and the second wavelength is the wavelength to which the third resonance may correspond.

[0449] In one embodiment, the first frame 210 further includes a fifth position 205, and the fourth position 204 is located between the third position 203 and the fifth position 205. The first frame 210 is coupled to the floor 300 at the fifth position 205.

[0450] In one embodiment, the second antenna 302 further includes a first parasitic stub 330. The first parasitic stub 330 includes a conductive portion of the first frame 210 between the fifth position 205 and the fourth position 204.

[0451] It should be understood that the first parasitic stub 330 can be used to improve the radiation characteristics of the second antenna 302 in the first frequency band and / or the second frequency band.

[0452] 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 300 MHz and greater than or equal to 100 MHz), the first parasitic resonance 330 can be used to improve the radiation efficiency of the second antenna 302 in the first frequency band and / or the second frequency band.

[0453] In one embodiment, when the parasitic resonance generated by the first parasitic stub 330 is far from the second resonance generated by the second radiator 320 (the frequency difference between the resonant point of the parasitic resonance and the resonant point of the second resonance is greater than or equal to 300 MHz), the first parasitic resonance 330 can be used to increase the beamwidth of the second antenna 302 in the first frequency band and / or the second frequency band. The current in the first parasitic stub 330 and the current in the second radiator 320 are in the same direction, which can enable the second antenna 302 to have better communication characteristics within a larger angle range between the side of the first parasitic stub 330 and the top direction.

[0454] 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.

[0455] It should be understood that in the above embodiment, 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 ground ends are close to each other).

[0456] It should be understood that the antennas described in this application may include parasitic branches, which can be used to improve the radiation characteristics of the antenna (for example, beam width, radiation efficiency, etc.). For the sake of brevity, they will not be described one by one.

[0457] In one embodiment, the first frame 210 is coupled to the floor 300 at the third position 203 and has a fourth insulating gap at the fourth position 204. 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 in FIG. 12 .

[0458] 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.

[0459] It should be understood that the second radiator 320 has a structure with one end grounded and the other end open. Similarly, in the electronic device 100 shown in FIG12 , the second radiator 320 can also form a metamaterial structure. For the sake of brevity, we will not describe it in detail one by one. You can refer to the metamaterial structure in the above embodiment for a corresponding understanding.

[0460] 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 in FIG. 13 .

[0461] 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) and 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) are different.

[0462] 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 embodiment. Similarly, reference may be made to the corresponding description in the above embodiment for understanding.

[0463] In one embodiment, both ends of the second radiator 320 are open ends, and the second radiator 320 can operate in a half-wavelength mode. The electrical length of the second radiator 320 is half of the second wavelength.

[0464] In one embodiment, the second radiator 320 may further include a second grounding point 352 , as shown in FIG14 . The second radiator 320 is coupled to the floor 300 at the second grounding point 352 .

[0465] In one embodiment, the second grounding point 352 may be located in the central area of ​​the second radiator 320 . The central area may be understood as an area within 5 mm from the center of the second radiator 320 . The lengths of the second radiators 320 on both sides of the center are the same.

[0466] It should be understood that by increasing the structural symmetry of the second antenna 302 , the second antenna 302 can have better communication performance.

[0467] In one embodiment, grounding can be achieved through a grounding member at the second grounding point 352. The width of the connection between the grounding member and the first frame 210 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0468] In one embodiment, when the grounding element includes at least a portion of the central area of ​​the second radiator 320 , the second grounding point 352 can be considered to be located in the central area of ​​the second radiator 320 .

[0469] It should be understood that when the second radiator 320 is coupled to the floor 300 at the second ground point 352, the second radiator 320 can also generate a fourth resonance in the line CM mode. The fourth resonance can be used to improve the radiation characteristics (e.g., radiation efficiency) of the second antenna 302 in the first frequency band and / or the second frequency band.

[0470] In one embodiment, the resonance point frequency of the third resonance may be higher than the resonance point frequency of the fourth resonance. The ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance may be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance may be greater than or equal to 1.3 and less than or equal to 1.5.

[0471] In one embodiment, a frequency difference between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance may be greater than or equal to 100 MHz and less than or equal to 500 MHz.

[0472] It should be understood that in the first frequency band (or the second frequency band), the second antenna 302 can operate in the linear DM mode. The fourth resonance can be used to improve the radiation characteristics (eg, radiation efficiency) of the second antenna 302 in the resonance frequency band of the third resonance.

[0473] In one embodiment, the resonance point frequency of the third resonance may be higher than the resonance point frequency of the fourth resonance. The ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance may be less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance.

[0474] 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 the linear CM mode and the linear DM mode, and radiation is jointly generated by the linear CM mode and the linear DM mode. The second antenna 302 has partial radiation characteristics of the linear CM mode and partial radiation characteristics of the linear DM mode.

[0475] In one embodiment, the ratio of the third resonance frequency to the fourth resonance frequency is less than or equal to 1.2. In one embodiment, the frequency difference between the first resonance frequency and the second resonance frequency is less than or equal to 300 MHz.

[0476] In one embodiment, the first antenna 301 and the second antenna 302 included in the electronic device 100 can be any first antenna 301 and any second antenna 302 shown in Figures 12 to 15, or can be any combination of the first antenna 301 and the second antenna 302.

[0477] It should be understood that when the difference between the first radiation pattern generated by the first antenna 301 and the second radiation pattern generated by the second antenna 302 is large, the electronic device 100 can perform satellite communication by switching the first antenna 301 and the second antenna 302, or, perform satellite communication through the first antenna 301 and the second antenna 302 at the same time, to have good communication quality in a larger area.

[0478] For example, when the first antenna 301 and the second antenna 302 are those shown in Figure 13 or Figure 14 (where the radiator does not include the ground point, as shown in Figure 14, or where the radiator includes the ground point, as shown in Figure 14), the operating mode of the first antenna 301 located at the top is the linear DM mode, with the electrical length of the entire branch section being approximately half a wavelength. Power is fed at one end of the first radiator 310, and the other end of the first radiator 310 is tuned via a capacitor or inductor. The middle region of the first radiator 310 may or may not be grounded. When the middle region of the first radiator 310 is grounded, the resonance generated by the linear CM mode is tuned before the resonance generated by the linear DM mode, resulting in the first antenna 301 having optimal radiation efficiency and an end-fire radiation pattern directed toward 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 of the second radiator 320 is tuned via a capacitor or inductor. The middle region of the second radiator 320 may or may not be grounded. When the middle region of second radiator 320 is grounded, the resonance generated by the line CM mode is tuned before the resonance generated by the line DM mode, so that the resonance of the second antenna during operation is exactly in the line DM mode, achieving a radiation pattern oriented toward one side. Because first antenna 301 and second antenna 302 can both achieve upper hemisphere coverage (the upper hemisphere region) and have a certain degree of complementarity in their directional patterns, wide-beam coverage can be achieved by combining the two antennas.

[0479] When the first antenna 301 and the second antenna 302 are the same as those shown in Figure 14 , the combined directional pattern of the first antenna 301 and the second antenna 302 has a coverage null on the left side. To enhance left-side coverage, an unbalanced linear DM mode is introduced into the design of the first antenna 301 located at the top (see first antenna 301 in Figure 15 ). Specifically, by adjusting the resonance generated by the linear CM mode closer to the resonance generated by the linear DM mode, the current generated by the linear DM mode is biased to the right, resulting in a current pattern with a strong right-side and weak left-side distribution. The corresponding directional pattern is then biased to the left. Therefore, combining this directional pattern with the second antenna 302 located at the waist yields a directional pattern that provides coverage on the top side (top direction), the left side (left of the top direction), and the right top direction. Therefore, combining the two antennas achieves improved wide-beam coverage.

[0480] In one embodiment, the structure of the first radiator 310 is the same as that of the second radiator 320 .

[0481] The same structure can be understood as the same boundary conditions, for example, one end is a grounded end and the other end is an open end, or both ends are open ends.

[0482] 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 through the first antenna 301 and the second antenna 302 to have good communication quality in a larger area.

[0483] Figures 16 and 17 are simulation results of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 14. Figure 16 is a simulation result of the S parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 14. Figure 17 is a simulation result of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 14.

[0484] It should be understood that for the sake of simplicity of discussion, only the combination of the first antenna 301 and the second antenna 302 in the electronic device 100 as shown in Figures 12 to 15 is used as an example for explanation. In actual production or design, the first antenna 301 in the combination can be any one of the first antennas shown in Figures 12 to 15, and the second antenna 302 in the combination can be any one of the second antennas shown in Figures 12 to 15. For the sake of simplicity of discussion, they will not be described one by one.

[0485] As shown in FIG16 , the first antenna ( S11 ) can resonate near 2.05 GHz and near 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 above second frequency band.

[0486] 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 may include the above second frequency band.

[0487] In the second frequency band (eg, 2170 MHz-2200 MHz), the isolation (S12 / S21) between the first antenna and the second antenna is greater than 15 dB, indicating good isolation between the first antenna and the second antenna.

[0488] As shown in FIG. 17 , when only the first antenna in the electronic device is working, in the second frequency band (eg, 2170 MHz-2200 MHz), the radiation efficiency of the first antenna is approximately -2.1 dB.

[0489] When only the second antenna is operating in the electronic device, the radiation efficiency of the second antenna is approximately -2.2 dB in the second frequency band (eg, 2170 MHz-2200 MHz).

[0490] When the first antenna and the second antenna in the electronic device operate simultaneously, in the second frequency band (eg, 2170 MHz-2200 MHz), the radiation efficiency of the first antenna decreases by approximately 0.4 dB, and the radiation efficiency of the second antenna decreases by approximately 0.4 dB.

[0491] Figures 18 and 19 illustrate the directional patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 14. Figure 18 illustrates the first directional pattern generated by the first antenna 301 in the electronic device 100 shown in Figure 14, and Figure 19 illustrates the second directional pattern generated by the second antenna 302 in the electronic device 100 shown in Figure 14.

[0492] As shown in FIG18 , the maximum radiation direction of the first directional pattern generated by the first antenna is toward the top direction of the electronic device (eg, the z direction).

[0493] As shown in FIG19 , the maximum radiation direction of the second directional pattern generated by the second antenna is toward the side direction of the electronic device (the direction perpendicular to the second side, for example, the y direction).

[0494] It should be understood that the angle between the maximum radiation direction of the first radiation pattern generated by the first antenna and the maximum radiation direction of the second radiation pattern generated by the second antenna is relatively large. The electronic device can switch the first antenna or the second antenna (or the first antenna and the second antenna work simultaneously) so that the communication satellite is always in an area where the electronic device has better radiation characteristics.

[0495] FIG20 is a schematic diagram of another electronic device 100 provided in an embodiment of the present application.

[0496] As shown in FIG. 20 , the electronic device 100 may include a first housing 211 , a second housing 212 , and a first rotation shaft 213 .

[0497] 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.

[0498] 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.

[0499] It should be understood that in the electronic device 100 shown in FIG20 , the electronic device 100 is a foldable electronic device, and the first rotation shaft 213 is directly connected to the first housing 211 and the second housing 212, respectively, enabling relative rotation of the first housing 211 and the second housing 212. Furthermore, the phrase "the first rotation shaft 213 is rotatably connected to the first housing 211 and the second housing 212" includes the case where the first rotation shaft 213 is rotatably connected to the first or second housing via one or more second rotation shafts and one or more intermediate housings. For example, in one embodiment, the electronic device 100 may further include a first rotation shaft and a second rotation shaft, and one or more intermediate housings located between the first rotation shaft and the intermediate housing. The first rotation shaft is located between the first housing 211 and the intermediate housing, and is rotatably connected to the first housing 211 and the intermediate housing, respectively, enabling relative rotation of the first housing 211 and the intermediate housing. The second rotation shaft is located between the intermediate housing and the second housing 212, and the first rotation shaft 213 is rotatably connected to the intermediate housing and the second housing 212, respectively, enabling relative rotation of the intermediate housing and the second housing 212.

[0500] It should be understood that the electronic device 100 shown in FIG. 20 is different from the electronic device 100 shown in FIG. 11 to FIG. 15 only in whether the electronic device 100 is foldable.

[0501] As shown in FIG. 20 , the electronic device 100 includes a first antenna 301 and a second antenna 302 .

[0502] The first antenna 301 may be any one of the first antennas shown in Figures 12 to 15 . The second antenna 302 may be any one of the second antennas shown in Figures 12 to 15 .

[0503] In one embodiment, the first antenna 301 can be a metamaterial structure (for example, the first antenna 301 shown in Figure 12), and the second antenna 302 can be a structure with open ends at both ends and including a second grounding point 352 (for example, the second antenna 302 shown in Figure 14), as shown in (a) in Figure 20.

[0504] In one embodiment, the first antenna 301 can be a structure with open ends at both ends and does not include the first grounding point 351 (for example, the first antenna 301 shown in Figure 13), and the second antenna 302 can be a metamaterial structure (for example, the second antenna 302 shown in Figure 12), as shown in (b) in Figure 20.

[0505] In one embodiment, the first antenna 301 can be a structure with open ends at both ends and including a first grounding point 351 (for example, the first antenna 301 shown in Figure 14), and the second antenna 302 can be a structure with open ends at both ends and not including a second grounding point 352 (for example, the second antenna 302 shown in Figure 13), as shown in (c) in Figure 20.

[0506] It should be understood that for the sake of simplicity, in the electronic device 100 shown in Figure 20, only the first antenna 301 is the first antenna 301 shown in any one of Figures 12 to 15, and the second antenna 302 is the second antenna 302 shown in any one of Figures 12 to 15 as an example for description.

[0507] For the sake of simplicity, the parts of the first antenna 301 and the second antenna 302 shown in Figures 12 to 15 that are similar to the first antenna 301 and the second antenna 302 shown in Figure 20 are not repeated one by one. For example, the similar parts include: the position and structure of the first radiator 310; the resonance generated by the first radiator 310; the position and structure of the second radiator 320; the resonance generated by the second radiator 320; the position of the first feeding point 312; the position of the second feeding point 322; the relationship between the first frequency band and the second frequency band; the equivalent inductance or equivalent capacitance values ​​of the corresponding elements when the first radiator 310 and the second radiator 320 are metamaterial structures; the position of the connection points on the radiators; and so on.

[0508] Figures 21 and 22 show simulation results for the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 20(a). Figure 21 shows the simulation results for the S parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 20(a). Figure 22 shows the simulation results for the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 20(a).

[0509] As shown in FIG. 21 , the first antenna ( S11 ) may resonate around 2.15 GHz, and the resonance around 2.15 GHz may correspond to the first resonance in the above embodiment.

[0510] The second antenna (S22) can resonate near 2.1 GHz and 2.3 GHz. The resonance near 2.1 GHz corresponds to the fourth resonance in the above-described embodiment, and the resonance near 2.3 GHz corresponds to the third resonance in the above-described 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 in both the linear CM mode and the linear DM mode.

[0511] In the second frequency band (eg, 2170 MHz-2200 MHz), the isolation (S12 / S21) between the first antenna and the second antenna is greater than 15 dB, indicating good isolation between the first antenna and the second antenna.

[0512] It should be understood that the simulation results shown in Figure 21 illustrate 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. It is generally believed that a depth of 3 dB or more can provide communication functions.

[0513] As shown in FIG. 22 , when only the first antenna in the electronic device is working, in the second frequency band (eg, 2170 MHz-2200 MHz), the radiation efficiency of the first antenna is approximately −1.89 dB.

[0514] When only the second antenna is operating in the electronic device, the radiation efficiency of the second antenna is approximately -2.8 dB in the second frequency band (eg, 2170 MHz-2200 MHz).

[0515] When the first antenna and the second antenna in the electronic device operate simultaneously, in the second frequency band (eg, 2170 MHz-2200 MHz), the radiation efficiency of the first antenna decreases by approximately 0.1 dB, and the radiation efficiency of the second antenna decreases by approximately 0.2 dB.

[0516] It should be understood that the simulation results shown in Figure 22 illustrate the radiation 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 radiation efficiency in the radiation efficiency curve may vary. It is generally believed that any value greater than -8 dB can provide communication functionality.

[0517] Figures 23 and 24 illustrate the directional patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 20(a). Figure 23 illustrates the first directional pattern generated by the first antenna 301 in the electronic device 100 shown in Figure 20(a). Figure 24 illustrates the second directional pattern generated by the second antenna 302 in the electronic device 100 shown in Figure 20(a).

[0518] As shown in Figure 23, since the floor of the electronic device 100 shown in Figure 20 is large, it is pulled by the current generated on the floor, and the maximum radiation direction of the first radiation pattern generated by the first antenna is toward the top direction of the electronic device (for example, the z direction) and deflected toward the side of the shell where the first antenna is not set (deflected toward the side of the second shell).

[0519] As shown in FIG. 24 , the maximum radiation direction of the second directional pattern generated by the second antenna is toward the top direction of the electronic device (eg, the z direction), and has good radiation on both sides of the top direction.

[0520] It should be understood that the angle between the maximum radiation direction of the first radiation pattern generated by the first antenna and the maximum radiation direction of the second radiation pattern generated by the second antenna is relatively large. The electronic device can switch the first antenna or the second antenna (or the first antenna and the second antenna work simultaneously) so that the communication satellite is always in an area where the electronic device has better radiation characteristics.

[0521] FIG25 is a schematic diagram of another electronic device 100 provided in an embodiment of the present application.

[0522] 25 , the second radiator 320 includes a second grounding point 352 , and the second grounding point 352 is coupled to the floor 300 . The second radiator 320 is attached to the back cover 21 of the electronic device 100 .

[0523] 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 via 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 in close proximity to the back cover 21 in the electronic device 100. "Close proximity" can be understood, for example, to mean that the distance between the second radiator 320 and the back cover 21 is within 5 mm, or that the distance between the second radiator and the back cover 21 is within 3 mm. In one embodiment, the second radiator 320 can be located on one side of the plane of the back cover 21.

[0524] In one embodiment, the second radiator 320 can be located on the inner side of the back cover 21 (close to the PCB 17), as shown in FIG26 . In one embodiment, the second radiator 320 can be located between the back cover 21 and the PCB 17. In one embodiment, the electronic device 100 can further include a bracket 251, and the second radiator 320 can be located on a surface of the bracket 251. In one embodiment, a shielding cover 15 can be provided between the bracket 251 and the PCB 17. In one embodiment, electronic components can be provided within the shielding cover 15 to prevent mutual interference between the electronic components and the second radiator 320.

[0525] 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 exterior surface of the electronic device 100 , a more flexible layout is provided.

[0526] In one embodiment, the second radiator 320 may be located outside the back cover 21 (away from the PCB 17), as shown in FIG27 . In one embodiment, the second radiator 320 may be a decorative piece (deco) of the camera module 252 of the electronic device 100. The decorative piece may be located on the outer surface of the camera module 252 and surround the camera module 252.

[0527] It should be understood that when the second radiator 320 is arranged on the outside of the electronic device 100, the radiation environment of the second antenna 302 is better (for example, the clearance is larger and the distance from the electronic components arranged on the PCB 17 is farther), and the second antenna 302 has better radiation characteristics (for example, radiation efficiency).

[0528] In one embodiment, the distance (eg, maximum distance) between the first radiator 310 and the second radiator 320 along the extension direction (eg, z-direction) of the second side 132 is less than or equal to half the length of the second side 132 .

[0529] It should be understood that the first radiator 310 and / or the second radiator 320 can be located in the upper half of the electronic device 100 (the area near the top), 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.

[0530] It should be understood that the electronic device 100 shown in FIG. 25 differs from the electronic devices 100 shown in FIG. 11 to FIG. 15 and FIG. 20 only in the structure and position of the second radiator 320. In the above embodiment, the second radiator 320 comprises a conductive portion of the first frame 210 between the third position 203 and the fourth position 204, with the third position 203 and the fourth position 204 located on the second side 132. In contrast, in the electronic device 100 shown in FIG. 25 , the second radiator 320 is a conductor attached to one side of the back cover 21. The first antenna 301 in the electronic device 100 shown in FIG. 25 can be any of the first antennas 301 shown in FIG. 11 to FIG. 15 . For simplicity, in this embodiment, the first antenna 301 shown in FIG. 14 will be used for illustration, and no further details will be given.

[0531] Because 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 good radiation in the top direction, thus having better radiation characteristics. The second antenna 302 can be used to improve the radiation performance of the electronic device 100 in the upper hemisphere. For example, the second antenna 302 can be used to enhance the radiation of the electronic device 100 in the top direction toward the second radiator 320, thereby enabling the electronic device 100 to have good communication characteristics over a wider range of angles from the top direction.

[0532] The upper hemisphere region can be understood as a region with an angle less than or equal to 90° with the top direction, and can be understood as a region with the xoy plane facing the positive z direction in the coordinate system.

[0533] In one embodiment, the second radiator 320 can have any shape. In one embodiment, the second radiator 320 can be annular, as shown in FIG25 . For example, the second radiator 320 can be a decorative piece of the camera module 252 of the electronic device 100. In one embodiment, the second radiator 320 can be in the form of a sheet, as shown in FIG28 .

[0534] It should be understood that the second radiator 320 can be in the shape of a bar (for example, the ratio of length to width is greater than or equal to 3), a circle, a trapezoid, a triangle, etc. The embodiment of the present application does not limit the shape of the second radiator 320, which can be determined based on actual production or design and will not be described in detail.

[0535] In one embodiment, the second radiator 320 may form a structure similar to a patch antenna.

[0536] It should be understood that the patch antenna can be understood as a radiator having a certain width (for example, the ratio of the length to the width of the radiator is less than or equal to 10), and the radiator is arranged face to face with the floor (for example, the plane where the radiator is located is approximately parallel to the plane where the floor is located).

[0537] In one embodiment, the second radiator 320 can be used to generate a third resonance and a fourth resonance. The resonance point frequency of the third resonance is higher than the resonance point frequency of the fourth resonance, and the ratio between the resonance point frequency of the third resonance and the resonance point frequency of the fourth resonance is less than or equal to 1.3. In one embodiment, the center frequency of the first frequency band (or the second frequency band) is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance.

[0538] In one embodiment, the second radiator 320 further includes a third grounding point 353 , and the second radiator 320 is coupled to the floor 300 at the third grounding point 353 .

[0539] 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 portion and a second portion. The second grounding point 352 is located in the first portion, and the third grounding point 353 is located in the second portion. 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 a 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.

[0540] It should be understood that the fourth resonance may be generated by the CM mode of the patch antenna, and the third resonance may be generated by the DM mode of the patch antenna.

[0541] In the above embodiments, the linear CM mode or the linear DM mode can be understood as the radiation generated by the linear antenna mainly by the current. The CM mode or the DM mode of the patch antenna can be understood as the radiation generated by the patch antenna mainly by the magnetic current (for example, the magnetic field between the radiator and the floor).

[0542] As shown in (a) in Figure 29, 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 grounding point 352 and the third grounding point 353 are located on the virtual ground line) (when the second radiator 320 includes only one grounding point, it can be understood as the side of the grounding point close to the second feeding point 322 and the side away from the second feeding point 322).

[0543] As shown in (b) of Figure 29, when the second radiator is ring-shaped, in the CM mode, the current on the second radiator 320 on both sides of the second grounding point 352 is reversed, the current on the second radiator 320 on both sides of the third grounding point 353 is reversed, and the current on the second radiator 320 between the second grounding point 352 and the third grounding point 353 is reversed.

[0544] As shown in FIG. 29( 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 line.

[0545] As shown in (d) of FIG29 , in the CM mode of the patch antenna, the radiation generated by the second antenna has two relatively strong regions. The two relatively strong radiation regions of the second antenna are respectively biased toward the top direction of the electronic device 100 (direction from the bottom edge to the top edge, for example, the positive direction of the z direction) and the bottom direction of the electronic device 100 (direction from the top edge to the bottom edge, for example, the negative direction of the z direction). The radiation generated by the second antenna in the thickness direction of the electronic device 100 (for example, the x direction) is relatively weak (having a null point on the radiation pattern, for example, the region where the gain is as low as 2%).

[0546] In the CM mode of the patch antenna, the electric field between the second radiator 320 and the floor 300 is in the same direction on both sides of the virtual ground line, but is partially opposite in direction in the far field of the second radiator 320 (for example, this can be understood by the fact that the circumferential electric field indicated by the curved arrows is partially opposite in direction), as shown in (e) in Figure 29. Therefore, the electric field of the first relatively strong radiation area in the directional pattern generated by the second antenna can be set to be biased toward the top of the electronic device 29 (from the bottom edge to the top edge, for example, in the positive direction of the z direction), and the electric field of the second relatively strong radiation area can be set to be biased toward the bottom of the electronic device 29 (from the top edge to the bottom edge, for example, in the negative direction of the z direction), wherein the far fields of the first and second relatively strong radiation areas have at least partially opposite electric field components (for example, there are opposite electric field components in the z direction).

[0547] As shown in (a) of FIG30 , 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 line.

[0548] As shown in (b) of Figure 30, when the second radiator is ring-shaped, in the DM mode, the current on the second radiator 320 on both sides of the second grounding point 352 is in the same direction, the current on the second radiator 320 on both sides of the third grounding point 353 is in the same direction, and the current on the second radiator 320 between the second grounding point 352 and the third grounding point 353 is in the opposite direction.

[0549] As shown in FIG. 30( 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.

[0550] As shown in (d) of Figure 30 , in the DM mode of the patch antenna, the radiation generated by the second antenna is stronger in the thickness direction (e.g., the x-direction) of the electronic device 100. The radiation generated by the second antenna is weaker (having a null point on the radiation pattern, e.g., a region where the gain is as low as 2%) in the top direction of the electronic device 100 (direction from the bottom edge to the top edge, e.g., the positive direction of the z-direction) and the bottom direction of the electronic device 100 (direction from the top edge to the bottom edge, e.g., the negative direction of the z-direction).

[0551] In the DM mode of the patch antenna, the electric field between the second radiator 320 and the floor 300 is in opposite directions on either side of the virtual ground line, but is in the same direction in the far field of the second radiator 320 (for example, this can be understood from the fact that the circumferential electric field indicated by the curved arrows is substantially in the same direction), as shown in (e) of Figure 30 . Therefore, the electric field pattern generated by the second antenna is in the same direction in the far field.

[0552] It should be understood that when the second antenna 302 operates in the CM mode of the patch antenna, the maximum radiation direction generated is biased toward the top direction (e.g., the positive direction in the z-direction) and the bottom direction (e.g., the positive direction in the z-direction). When the second antenna 302 operates in the DM mode of the patch antenna, the maximum radiation direction generated is biased toward 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 point frequency of the fourth resonance and less than the resonant point frequency of the third resonance. In the first frequency band, the second antenna 302 radiates from both the CM mode and the DM mode of the patch antenna.

[0553] Since the directional pattern generated by the CM mode of the patch antenna has at least partially opposite electric field components in the electric fields of the two stronger radiation areas, and the directional pattern generated by the DM mode of the patch antenna has the electric fields in the stronger radiation areas in the same direction, the directional pattern generated by the DM mode of the patch antenna can enhance one of the two stronger radiation areas generated by the CM mode of the patch antenna and weaken the other one.

[0554] The second antenna 302 generates radiation jointly by the CM mode and DM mode of the patch antenna, which can enhance the radiation of the directional pattern generated by the second antenna 302 in the top direction (for example, the positive direction of the z direction) and weaken the radiation in the bottom direction (for example, the positive direction of the z direction), thereby enabling the second antenna 302 to have better radiation characteristics in the top direction, so that the electronic device 100 has better communication performance.

[0555] In one embodiment, when the second radiator 320 is ring-shaped, the length difference between the second radiator 320 on both sides of the virtual ground line (the virtual ground line is the line connecting the second ground point 352 and the third ground point 353 ) is within 20%.

[0556] It should be understood that as the symmetry increases, the radiation characteristics of the second antenna 302 are better.

[0557] In one embodiment, the ratio of the third resonance frequency to the fourth resonance frequency is less than or equal to 1.2. In one embodiment, the frequency difference between the fourth resonance frequency and the third resonance frequency is less than or equal to 300 MHz.

[0558] It should be understood that when the resonance point of the third resonance is close to the resonance point of the fourth resonance, the second antenna 302 has better radiation characteristics in the first frequency band (or the second frequency band) (for example, the proportion of the directivity pattern increases toward the top).

[0559] In one embodiment, the minimum distance between the first radiator 310 and the second radiator 320 is less than or equal to 20 mm. In one embodiment, the distance between the first radiator 310 and the second radiator 320 is less than or equal to 10 mm.

[0560] 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 one embodiment, the distance between the first feed point 312 and the second feed point 322 is less than or equal to 10 mm.

[0561] It should be understood that when the first radiator and the second radiator are both fed by electrical connection, the distance between the first feeding point 312 and the second feeding point 322 can be understood as the distance between the center of the area where the first metal part used to feed the first antenna 301 contacts the first radiator 310 and the center of the area where the second metal part used to feed the second antenna 302 contacts the second radiator 320.

[0562] When the first radiator and the second radiator are both fed by indirect coupling, the distance between the first feeding point 312 and the second feeding point 322 can be understood as the distance between the center of the projection of the end of the first metal part used to feed the first antenna 301 toward the first radiator 310 on 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 part used to feed the second antenna 302 toward the second radiator 320 on the second radiator 320 (along the thickness direction of the electronic device 100).

[0563] When the first radiator 310 and the second radiator 320 are fed by electrical connection and indirect coupling respectively, the above embodiments may be referred to for corresponding understanding.

[0564] When the distance between the first feeding point 312 and the second feeding point 322 is close, the transmission line distance between the RF channel in the RF chip (for example, the first feeding circuit 311 and the second feeding circuit 321) and the corresponding feeding point (for example, the first feeding point 312 or the second feeding point 322) is shorter, and the loss of the RF signal output by the RF channel on the transmission path is smaller, which is beneficial to improving the radiation characteristics (for example, gain) of the antenna (the first antenna 301 or the second antenna 302).

[0565] In one embodiment, the second antenna 302 may further include a fourth element 334, as shown in FIG31 . The second radiator 320 may further include a seventh connection point 347. The fourth element 334 may be coupled between the seventh connection point 347 and the floor 300.

[0566] 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., the direction of maximum radiation) of the second antenna 302 in the first frequency band (or the second frequency band). The fourth element 334 can adjust the frequency difference between the resonance point of the third resonance and the resonance point of the fourth resonance. This allows the center frequency of the first frequency band (or the second frequency band) to be relatively close to the resonance point of the third resonance or the resonance point of the fourth resonance, thereby adjusting the radiation characteristics (e.g., the direction of maximum radiation) of the second antenna 302 in the first frequency band (or the second frequency band). The fourth element 334 coupled between the floor 300 and the seventh connection point 347 can increase the flexibility of adjusting the second antenna 302.

[0567] 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°.

[0568] It should be understood that the angle between the seventh connection point 347 and the second feed point 322 can be understood as the smaller angle among the angles between the seventh connection point 347 and the second feed point 322 relative to the center of the second radiator 320, or can also be understood as the angle between the seventh connection point 347 and the second feed point 322 relative to the center of the second radiator 320 that is less than or equal to 180°. 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.

[0569] 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 1 pF.

[0570] In one embodiment, the fourth element 334 may be an inductor, or an element equivalent to an inductor.

[0571] The second antenna 302 may further include a switch 340 and a plurality of elements, as shown in FIG32. In one embodiment, the second antenna 302 may include a fourth element 334 and a fifth element 335.

[0572] For the sake of simplicity, in the electronic device 100 shown in FIG32 , only a single-pole four-throw (DPFT) switch 340 is used as an example for description. In actual production or design, replacements may be made. For example, the switch 340 may be a double-pole X-throw (DPXT) switch, or a multi-pole multi-throw (X-pole X-throw, XPXT) switch, or a combination of multiple single-pole single-throw (SPST) switches. The embodiments of the present application do not limit this, and the switches described in the embodiments of the present application may be understood accordingly.

[0573] The switch 340 is coupled between the seventh connection point 347 and the floor 300. A plurality of elements (eg, 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.

[0574] In one embodiment, the element coupled between the floor panel 300 and the seventh connection point 347 may be used to switch the radiation characteristics (eg, the maximum radiation direction) of the second antenna 302 in the first frequency band (or the second frequency band).

[0575] It should be understood that the electronic device 100 shown in FIG31 may include only one element (e.g., the fourth element 334). However, the electronic device 100 shown in FIG32 includes multiple elements (e.g., the fourth element 334 and the fifth element 335). The equivalent capacitance or equivalent inductance of the element coupled between the seventh connection point 347 and the floor 300 can be switched by the switch 340, or the boundary condition 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 floor 300, or the seventh connection point 347 can be directly electrically connected to the floor 300 (without any element), thereby adjusting the frequency difference between the resonance point of the third resonance and the resonance point of the fourth resonance.

[0576] By adjusting the frequency difference between the resonance point of the third resonance and the resonance point of the fourth resonance, the center frequency of the first frequency band can be made relatively close to the resonance point of the third resonance or the resonance point of the fourth resonance. For example, the fourth element 334 and the second radiator 320 are used to generate the third resonance 1 and the fourth resonance 1. The fifth element 335 and the second radiator 320 are used to generate the third resonance 2 and the fourth resonance 2. The first frequency difference and the second frequency difference are different, the first frequency difference being the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the third resonance 1, and the second frequency difference being the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the third resonance 2. Alternatively, the third frequency difference and the fourth frequency difference are different, the third frequency difference being the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the fourth resonance 1, and the fourth frequency difference being the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the fourth resonance 2.

[0577] 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., maximum radiation direction) of the second antenna 302 in the first frequency band (or the second frequency band) can be adjusted, thereby achieving the switching of the radiation characteristics (e.g., maximum radiation direction) of the second antenna 302 in the first frequency band.

[0578] In one embodiment, the element coupled between the floor panel 300 and the seventh connection point 347 can be used to switch the operating frequency band of the second antenna 302 .

[0579] It should be understood that the electronic device 100 shown in FIG31 may include only one element (e.g., fourth element 334). However, the electronic device 100 shown in FIG32 includes multiple elements (e.g., fourth element 334 and fifth element 335). Switch 340 can be used to switch the equivalent capacitance or equivalent inductance of the element coupled between seventh connection point 347 and floor 300. Alternatively, switch 340 can be used to switch the boundary conditions of seventh connection point 347, for example, disconnecting seventh connection point 347 from floor 300 or directly electrically connecting seventh connection point 347 to floor 300 (without any element). This allows adjustment of the resonant frequency of the third resonance and the resonant frequency of the fourth resonance. For example, fourth element 334 and second radiator 320 are used to generate third resonance 1 and fourth resonance 1. Fifth element 335 and second radiator 320 are used to generate third resonance 2 and fourth resonance 2. The center frequency of the first frequency band is less than the resonant frequency of fourth resonance 1 and greater than the resonant frequency of third resonance 1. The center frequency of the second frequency band is less than the resonance point frequency of the fourth resonance 2 and greater than the resonance point frequency of the third resonance 2. The operating frequency band of the second antenna 302 can be switched by switching the fourth element 334 and the fifth element 335.

[0580] In one embodiment, when the electronic device 100 is not performing satellite communication, the switch 340 can also be used to switch the operating frequency band of the second antenna 302 to achieve antenna reuse. For example, the second antenna can also be used as a cellular antenna, a WiFi antenna, etc., which will not be described in detail.

[0581] It should be understood that in the electronic device 100 shown in Figures 25 to 28 and Figures 31 and 32, the first antenna 301 located at the top is the same as the first antenna 301 shown in Figures 12 to 15 and will not be described again. The second antenna 302 attached to the back cover 21 of the electronic device 100 can be simplified as a patch antenna with a grounded center, its overall electrical size is half a wavelength, the upper end of the second radiator 320 (close to the side of the first radiator 310) is fed, and the lower end of the second radiator 320 is tuned by connecting a capacitor or inductor device. By adjusting the resonant device generated by the patch antenna's CM mode, the patch antenna's CM mode resonance is tuned before the DM mode resonance, so that the second antenna 302 has a combination of currents in the patch antenna's CM and DM modes within the operating frequency band. This results in the current distribution on the second radiator 320 being biased toward the upper hemisphere (the region near the first radiator 310). Its directional pattern is also a superposition of the directional patterns generated by the patch antenna's CM and DM modes, resulting in a directional pattern that primarily radiates toward the top. Therefore, by superimposing the directional patterns of the first antenna 301 and the second antenna 302, located at the top, a good merging benefit can be achieved.

[0582] Furthermore, since the second radiator 320 of the second antenna 302 does not include the conductive portion of the first frame, the system cost of compatible design when the conductive portion of the first frame is reused as a satellite antenna and a cellular antenna can be reduced.

[0583] For the sake of simplicity, the parts of the first antenna 301 and the second antenna 302 shown in Figures 12 to 15 that are similar to the first antenna 301 and the second antenna 302 shown in Figure 20 are not repeated one by one. For example, the similar parts include: the position and structure of the first radiator 310; the resonance generated by the first radiator 310; the position of the first feeding point 312; the relationship between the first frequency band and the second frequency band; the equivalent inductance or equivalent capacitance value of the corresponding element when the first radiator 310 is a metamaterial structure; the position of the connection point on the radiator; and so on.

[0584] Figures 33 and 34 are simulation results of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 31. Figure 33 is a simulation result of the S parameters of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 31. Figure 34 is a simulation result of the radiation efficiency of the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 31.

[0585] As shown in Figure 33, the first antenna (S11) can resonate around 1.95 GHz and around 2.2 GHz. The resonance around 1.95 GHz corresponds to the second resonance in the above embodiment, and the resonance around 2.2 GHz corresponds to the first resonance in the above embodiment.

[0586] The second antenna (S22) can resonate near 1.95 GHz and 2.25 GHz. The resonance near 1.95 GHz corresponds to the fourth resonance in the above-described embodiment, and the resonance near 2.25 GHz corresponds to the third resonance in the above-described embodiment. The center frequency of the second frequency band is greater than the resonant point frequency of the fourth resonance and less than the resonant point frequency of the third resonance. In the second frequency band, the second antenna radiates in both the CM and DM modes of the patch antenna.

[0587] In the second frequency band (eg, 2170 MHz-2200 MHz), the isolation (S12 / S21) between the first antenna and the second antenna is greater than 13 dB, indicating good isolation between the first antenna and the second antenna.

[0588] As shown in FIG34 , when the first antenna and the second antenna in the electronic device operate simultaneously, in the second frequency band (eg, 2170 MHz-2200 MHz), the radiation efficiency of the first antenna is approximately -2.2 dB, and the radiation efficiency of the second antenna is approximately -4.7 dB.

[0589] It should be understood that the simulation results shown in Figure 34 illustrate the radiation 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 radiation efficiency in the radiation efficiency curve may vary. It is generally believed that any value greater than -8 dB can provide communication functionality.

[0590] Figures 35 and 36 illustrate the directional patterns generated by the first antenna 301 and the second antenna 302 in the electronic device 100 shown in Figure 31. Figure 35 illustrates the first directional pattern generated by the first antenna 301 in the electronic device 100 shown in Figure 31. Figure 36 illustrates the second directional pattern generated by the second antenna 302 in the electronic device 100 shown in Figure 32.

[0591] As shown in FIG35 , the maximum radiation direction of the first directional pattern generated by the first antenna is toward the top direction of the electronic device (eg, the z direction), and the first antenna has good radiation characteristics in the area near the top direction.

[0592] As shown in Figure 36, since the center frequency of the second frequency band is greater than the resonance point frequency of the fourth resonance and less than the resonance point frequency of the third resonance, in the first frequency band, the second antenna 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 (for example, the z direction), which can better communicate with the communication satellite.

[0593] FIG37 is a schematic diagram of another electronic device 100 provided in an embodiment of the present application.

[0594] As shown in FIG. 37 , the electronic device 100 may include a first bezel 210 .

[0595] The first frame 210 includes a first position 201, a second position 202, a third position 203, and a fourth position 204. At least a portion of the first frame 210 is spaced apart from the floor 300.

[0596] It should be understood that the sequential arrangement described in the embodiments of the present application can be understood as being arranged 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. The third position 203 will not be 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 simplicity, the sequential arrangement described in the embodiments of the present application can be understood accordingly and will not be detailed one by one.

[0597] The overlap of the second position 202 and the third position 203 can be understood as the same as the second position 202 and the third position 203. For the sake of simplicity, the overlap described in the embodiments of this application can be understood accordingly and will not be repeated one by one.

[0598] The first frame 210 has an insulating gap at a first position 201 or is coupled to the floor 300. The first frame 210 has an insulating gap at a second position 202 or is coupled to the floor 300. The first frame 210 has an insulating gap at a third position 203 or is coupled to the floor 300. The first frame 210 has an insulating gap at a fourth position 204 or is coupled to the floor 300.

[0599] 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 shorter than the length of the second side 132. The length of the first side 131 is shorter than the length of the third side 133. In one embodiment, the first side 131 can be understood as a short side of the electronic device 100.

[0600] The electronic device 100 includes a first antenna 301 and a second antenna 302 .

[0601] 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-mentioned embodiment. The electronic device 100 may perform satellite communication via the first antenna 301 and / or the second antenna 302.

[0631] In one embodiment, the second position 202 and the third position 203 coincide.

[0632] In one embodiment, similarly, in the first antenna 301 shown in FIG40 , the first radiator 310 may also include a first grounding point 351 , which will not be described in detail for the sake of brevity.

[0634] 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-shaped antenna or a left-handed antenna.

[0635] When the first radiator 310 forms a shape similar to an inverted F-type antenna, the first feeding point 312 is close to the ground end, and the distance between the first feeding point 312 and the ground end (the length of the first radiator 310 between the first feeding point 312 and the first position 201) is less than or equal to half the length of the first radiator 310.

When the first feed point 312 is located near the open end, this facilitates miniaturization of the first radiator 310. A capacitor is coupled between the first feed circuit 311 and the first feed point 312 to better excite the first radiator 310.

[0637] For the sake of simplicity, when a structure similar to an inverted F-type antenna or a left-hand antenna is formed, it can be understood accordingly in the application embodiments and will not be described in detail.

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

[0641] It should be understood that for simplicity of discussion, in the embodiment of the present application, only an example is given in which a frame 210 has an insulating gap at the fifth position 205 and is coupled with the floor 300 at the sixth position 206 .

[0643] It should be understood that the first parasitic branch 371 is used to generate a first parasitic resonance, which can be used to suppress the current on the floor 300 near the second side 132, thereby reducing the component of the radiation pattern corresponding to the first resonance toward the bottom of the electronic device 100 (the direction from the top of the electronic device 100 to the bottom), thereby increasing the component of the direction toward the top of the electronic device 100, and improving the radiation characteristics (for example, gain) of the first antenna 301 in the top direction.

In one embodiment, the resonance point of the first parasitic resonance is located within the resonance frequency band of the first main resonance.

[0645] At the same time, in an embodiment of the present application, the coupling between the first radiator 310 and the first parasitic branch 371 is weak, and the first parasitic resonance cannot be well excited. Therefore, the pit corresponding to the first parasitic resonance does not appear clearly in the S-parameter diagram. However, since the first parasitic resonance is partially excited by current, an obvious pit will appear in the efficiency curve (for example, radiation efficiency or system efficiency). For example, if an efficiency pit appears at the first frequency point, the first frequency point can be considered to correspond to the resonance point of the above-mentioned first parasitic resonance. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1.5dB. In one embodiment, the efficiency (for example, radiation efficiency or system efficiency) caused by the pit does not exceed 1dB.

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 in FIG38 .

[0652] 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) and 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) are different.
