Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to an electronic device. Background Art

[0002] When users conduct satellite communications, they need to point the area where the antenna has better radiation characteristics (for example, the gain of the antenna in this area is greater than or equal to AdBic, where A is the minimum gain value that meets the communication requirements in the satellite communication system) towards the satellite to achieve satellite alignment (establishing a communication connection with the satellite).

[0003] However, during satellite communications, the antenna's radiation characteristics can change due to the human body's influence on how the user holds the device. For example, if the conductive portion of the device's frame acts as the antenna's radiator and the user holds the device to their ear and uses the receiver for a voice call, the antenna's maximum radiation direction will deviate from the top of the device due to the influence of the human body, reducing gain and radiation efficiency, significantly impacting the user's communication experience. Summary of the Invention

[0004] The present application provides an electronic device including a first antenna and a second antenna. The electronic device can switch between the first antenna and the second antenna according to different holding postures of the user, thereby improving the user's experience when performing satellite communications.

[0005] In a first aspect, an electronic device is provided, comprising: a floor; a frame, the frame comprising a first position and a second position, the frame having an insulating gap at the first position or being coupled to the floor, and the frame having an insulating gap at the second position or being coupled to the floor; a first antenna, the first antenna comprising: a first radiator, the first radiator comprising a conductive portion of the frame between the first position and the second position, at least a portion of the first radiator being spaced apart from the floor; a second antenna, the second antenna comprising: a second radiator, the second radiator comprising a first grounding point, the first grounding point being coupled to the floor, the second radiator being attached to a back cover of the electronic device, and at least a portion of the second radiator being spaced apart from the floor; the electronic device further comprising: a first feeding circuit, the first The feeding circuit is used to transmit a radio frequency signal in a first frequency band, wherein the first frequency band includes a transmission frequency band in a satellite communication frequency band, the first radiator includes a first feeding point, the second radiator includes a second feeding point, the first feeding circuit is coupled to the first feeding point, and the first feeding circuit is coupled to the second feeding point; wherein the border includes a first side and a second side that intersect at an angle, the first position and the second position are located on the first side, and the length of the first side is less than the length of the second side; the maximum distance between the first radiator and the second radiator along the extension direction of the second side is less than or equal to half the length of the second side; at a first time, the electronic device performs satellite communication in the first frequency band by the first antenna; at a second time, the electronic device performs satellite communication in the first frequency band by the second antenna.

[0006] According to embodiments of the present application, when conducting satellite communications (e.g., satellite calls), the antenna's radiation characteristics may vary depending on the user's grip on the electronic device. This allows the electronic device to switch antennas connected to the communication satellite at different times, ensuring consistent communication quality regardless of the user's grip.

[0007] At the same time, the first radiator and / or the second radiator can be located in the upper half of the electronic device 10 (the area close to the top), which is more conducive to the radiation generated by the first antenna and / or the second antenna in the top direction, so that the electronic device and the communication satellite have good communication quality.

[0008] In combination with the first aspect, in some implementations of the first aspect, at the first time, the electronic device is in a non-earpiece mode; at the second time, the electronic device is in an earpiece mode.

[0009] According to an embodiment of the present application, when a user uses handset mode for satellite communication, the user's head is close to the handset, and the electronic device performs satellite communication via the second antenna (for example, transmitting signals to a communication satellite in the first frequency band). Because the second antenna is attached to the back cover of the electronic device, when the user holds the electronic device in handset mode, satellite communication via the second antenna (for example, transmitting signals to a communication satellite in the first frequency band) will have better communication performance.

[0010] When a user uses a non-earpiece mode (e.g., hands-free mode or Bluetooth mode) for satellite communication, the user's head is away from the earpiece, and the electronic device uses the first antenna to perform satellite communication (e.g., transmits signals to a communication satellite in a first frequency band). Because the first radiator of the first antenna is located on a short side of the electronic device, when the user holds the electronic device in a non-earpiece mode (e.g., hands-free mode or Bluetooth mode), the electronic device uses the first antenna to perform satellite communication (e.g., transmits signals to a communication satellite in a first frequency band) with better communication performance.

[0011] In combination with the first aspect, in some implementations of the first aspect, the electronic device further includes a first switch, a first common port of the first switch is coupled to the first feeding circuit, a first connection port of the first switch is coupled to the first feeding point, and a second connection port of the first switch is coupled to the second feeding point.

[0012] According to an embodiment of the present application, in an electronic device, a feeding point (for example, a first feeding point or a second feeding point) coupled to a first feeding circuit can be switched by a first switch, so that the electronic device can switch the antenna connected to the communication satellite at different times.

[0013] In combination with the first aspect, in certain implementations of the first aspect, the electronic device further includes: a second feeding circuit, the second feeding circuit being used to transmit a radio frequency signal in a second frequency band, the second frequency band including a receiving frequency band in a satellite communication frequency band; wherein the second feeding circuit is coupled to the first feeding point, and the second feeding circuit is coupled to the second feeding point; at a third time, the electronic device performs satellite communication in the second frequency band by the first antenna; and at a fourth time, the electronic device performs satellite communication in the second frequency band by the second antenna.

[0014] According to an embodiment of the present application, when an electronic device performs satellite communication, it can communicate with a communication satellite via an antenna within the electronic device. In this case, the antenna can be loaded with different electronic components at different times to adjust the resonant point frequency, thereby allowing the antenna to operate in the satellite system's transmit and receive frequency bands at different times.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the electronic device further includes: a second feeding circuit and a third feeding circuit, the second feeding circuit being coupled to the first feeding point, the third feeding circuit being coupled to the second feeding point, the second feeding circuit and the third feeding circuit being both used to transmit radio frequency signals in a second frequency band, the second frequency band including a receiving frequency band in a satellite communication frequency band; wherein, at a third time, the electronic device performs satellite communication in the second frequency band through the first antenna and the second antenna.

[0016] According to an embodiment of the present application, an electronic device simultaneously performs satellite communication in a second frequency band via a first antenna and a second antenna (e.g., receives signals transmitted by a communication satellite in the second frequency band). The signals transmitted by the communication satellite received by the first antenna and the second antenna in the second frequency band can be superimposed using an algorithm or other means, thereby enhancing the communication quality between the electronic device and the communication satellite.

[0017] In combination with the first aspect, in some implementations of the first aspect, a minimum distance between the second radiator and the first radiator is less than or equal to 20 mm.

[0018] According to an embodiment of the present application, since the first radiator is located at the top edge of the electronic device, when the second radiator attached to the back cover is arranged adjacent to the first radiator, satellite communication can be switched between the first radiator and the second radiator without the need to perform the satellite alignment operation again, and both have good radiation characteristics.

[0019] In combination with the first aspect, in some implementations of the first aspect, a distance between the first feeding point and the second feeding point is less than or equal to 20 mm.

[0020] According to an embodiment of the present application, when the distance between the first feeding point and the second feeding point is close, the transmission line distance between the RF channel (first feeding circuit) and the feeding point (for example, the first feeding point or the second feeding point) is short, and the loss of the RF signal output by the RF channel on the transmission path is small, which is beneficial to improving the radiation characteristics (for example, gain) of the antenna (the first antenna or the second antenna).

[0021] In combination with the first aspect, in some implementations of the first aspect, the frame has a first insulating gap and a second insulating gap at the first position and the second position, and the distance between the first feeding point and the first position is different from the distance between the first feeding point and the second position.

[0022] According to an embodiment of the present application, the resonance generated by the first radiator can be generated by a line DM mode. The directional pattern generated by the line DM mode does not have a strong current flowing to the floor. Therefore, the current on the floor is small, and the influence of the floor on the directional pattern generated by the line DM mode is similar to that of a reflector. As a result, the directional pattern generated by the line DM mode is mainly toward the top direction of the electronic device (the direction in which the first radiator is away from the floor, for example, the z direction). However, the directional pattern generated by the line CM mode, because the current flowing to the floor in the line CM mode is strong, the current on the floor is large, and the floor has a great influence on the directional pattern generated by the antenna. As a result, the directional pattern generated by the line CM mode is not mainly toward the top direction of the electronic device (the direction in which the first radiator is away from the floor, for example, the z direction).

[0023] 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).

[0024] In combination with the first aspect, in certain implementations of the first aspect, the second radiator is in a sheet shape; the second radiator also includes a second grounding point, which is coupled to the floor; wherein the second radiator includes a first center line, the second feeding point and the center of the second radiator are located on the first center line, the first center line divides the second radiator into a first part and a second part, the first grounding point is located in the first part, and the second grounding point is located in the second part.

[0025] According to an embodiment of the present application, the second radiator 220 may form a structure similar to a patch antenna.

[0026] In combination with the first aspect, in some implementations of the first aspect, the second radiator is ring-shaped.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the second radiator is used to generate a first resonance and a second resonance, the resonance point frequency of the second resonance is higher than the resonance point frequency of the first resonance, and the ratio between the resonance point frequency of the second resonance and the resonance point frequency of the first resonance is less than or equal to 1.3.

[0028] In combination with the first aspect, in some implementations of the first aspect, the center frequency of the first frequency band is less than the resonance point frequency of the second resonance and greater than the resonance point frequency of the first resonance.

[0029] According to an embodiment of the present application, the first resonance can be generated by the CM mode of the patch antenna, and the second resonance can be generated by the DM mode of the patch antenna. When the second antenna operates in the CM mode of the patch antenna, the maximum radiation direction generated is biased towards the top direction (for example, the positive direction of the z direction) and the bottom direction (for example, the positive direction of the z direction). When the second antenna operates in the DM mode of the patch antenna, the maximum radiation direction generated is biased towards the thickness direction (for example, the x direction). In the first frequency band, the second antenna is radiated by the mode and mode of the patch antenna. The radiation pattern generated by the second antenna is enhanced in the top direction (for example, the positive direction of the z direction) and weakened in the bottom direction (for example, the positive direction of the z direction), so that the second antenna 302 can have better radiation characteristics in the top direction.

[0030] In combination with the first aspect, in some implementations of the first aspect, the second radiator is ring-shaped; at the resonance point of the first resonance, the currents on the second radiators on both sides of the first grounding point are reversed, the currents on the second radiators on both sides of the second grounding point are reversed, and the currents on the second radiator between the first grounding point and the second grounding point are reversed; at the resonance point of the second resonance, the currents on the second radiators on both sides of the first grounding point are in the same direction, the currents on the second radiators on both sides of the second grounding point are in the same direction, and the currents on the second radiator between the first grounding point and the second grounding point are reversed.

[0031] According to an embodiment of the present application, the first resonance may be generated by the CM mode of the patch antenna, and the second resonance may be generated by the DM mode of the patch antenna. The CM mode and the DM mode of the patch antenna may correspond to the above-mentioned current distribution.

[0032] In combination with the first aspect, in certain implementations of the first aspect, the second radiator further includes a connection point, and the angle between the connection point and the second feeding point relative to the center of the second radiator is greater than or equal to 45°; the second antenna further includes a first element, and the first element is coupled and connected between the connection point and the floor.

[0033] According to an embodiment of the present application, in one embodiment, the angle between the connection point and the second feed point is greater than or equal to 135°. As the angle between the connection point and the second feed point increases, the adjustable range of the first element further increases. In conjunction with the first aspect, in certain implementations of the first aspect, the second antenna further includes a second switch and a second element, the second switch being coupled and connected between the connection point and the floor, and the first element and the second element being connected in parallel between the second switch and the connection point or between the second switch and the floor.

[0034] In combination with the first aspect, in some implementations of the first aspect, the first element and the second radiator are used to generate a first resonance and a second resonance, the resonance point frequency of the second resonance is higher than the resonance point frequency of the first resonance, the center frequency of the first frequency band is lower than the resonance point frequency of the second resonance, and higher than the resonance point frequency of the first resonance; the second element and the second radiator are used to generate a third resonance and a fourth resonance, the resonance point frequency of the fourth resonance is higher than the resonance point frequency of the third resonance, the center frequency of the first frequency band is lower than the resonance point frequency of the fourth resonance, and higher than the resonance point frequency of the third resonance; wherein the first frequency difference and the second frequency difference are different, the first frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the first resonance, the second frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the third resonance, and / or the third frequency difference and the fourth frequency difference are different, the third frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the second resonance, and the fourth frequency difference is the frequency difference between the center frequency of the first frequency band and the resonance point frequency of the fourth resonance.

[0035] According to an embodiment of the present application, the element coupled between the floor and the connection point can be used to switch the radiation characteristics (e.g., the direction of maximum radiation) of the second antenna in the first frequency band. For example, because the center frequency of the first frequency band can be relatively close to the resonance point of the resonance generated by the CM mode or the resonance point of the resonance generated by the DM mode, the radiation characteristics (e.g., the direction of maximum radiation) of the second antenna in the first frequency band can be adjusted, thereby achieving switching of the radiation characteristics (e.g., the direction of maximum radiation) of the second antenna in the first frequency band.

[0036] In combination with the first aspect, in some implementations of the first aspect, the first element and the second radiator are used to generate a first resonance and a second resonance, the resonance point frequency of the second resonance is higher than the resonance point frequency of the first resonance, and the center frequency of the first frequency band is less than the resonance point frequency of the second resonance, and greater than the resonance point frequency of the first resonance; the second element and the second radiator are used to generate a third resonance and a fourth resonance, the resonance point frequency of the fourth resonance is higher than the resonance point frequency of the third resonance, the center frequency of the second frequency band is less than the resonance point frequency of the fourth resonance, and greater than the resonance point frequency of the third resonance, and the second frequency band includes a receiving frequency band in the satellite communication frequency band.

[0037] According to an embodiment of the present application, the element coupled between the floor and the connection point 230 can be used to switch the operating frequency band of the second antenna, so that the second antenna can operate in different satellite communication frequency bands at different times.

[0038] In combination with the first aspect, in certain implementations of the first aspect, the second antenna further includes a power divider phase shifter; wherein the second radiator further includes a third feeding point; the first port of the power divider phase shifter is coupled to the first feeding circuit, the second port of the power divider phase shifter is coupled to the second feeding point, and the third port of the power divider phase shifter is coupled to the third feeding point.

[0039] According to an embodiment of the present application, the radiation characteristics (eg, maximum radiation direction) of the second antenna in the first frequency band can be switched by controlling the phase difference between the RF signals fed into the second feeding point and the third feeding point.

[0040] In combination with the first aspect, in some implementations of the first aspect, the second feeding point and the third feeding point are respectively located on both sides of a virtual ground line, and the virtual ground line is a line connecting the first ground point and the second ground point.

[0041] In combination with the first aspect, in certain implementations of the first aspect, the second radiator is ring-shaped; the second feeding point and the third feeding point divide the second radiator into a third part and a fourth part, and the length L1 of the third part and the length L2 of the fourth part satisfy: L2×90%≤L1≤L2×120%.

[0042] According to the embodiment of the present application, as the structural symmetry of the second antenna increases, the second antenna has better radiation characteristics.

[0043] In combination with the first aspect, in certain implementations of the first aspect, the second radiator is a decorative piece of a camera module of the electronic device, and the second radiator is disposed on the outer side of the back cover.

[0044] In combination with the first aspect, in some implementations of the first aspect, the electronic device further includes a bracket, and the second radiator is located on a surface of the bracket.

[0045] According to a second aspect, an electronic device is provided, comprising: a floor; a frame, the frame comprising a first position and a second position, the frame having an insulating gap or coupling with the floor at the first position, and the frame having an insulating gap or coupling with the floor at the second position; a first antenna, the first antenna comprising: a first radiator, the first radiator comprising a conductive portion of the frame between the first position and the second position, at least a portion of the first radiator being spaced apart from the floor; a second antenna, the second antenna comprising: a second radiator, the second radiator comprising a first grounding point, the first grounding point being coupled with the floor, the second radiator being attached to a back cover of the electronic device, at least a portion of the second radiator being spaced apart from the floor; wherein, at a first time, the electronic device performs satellite communication in a first frequency band using the first antenna, the first frequency band comprising a transmit frequency band within a satellite communication frequency band; and at a second time, the electronic device performs satellite communication in the first frequency band using the second antenna; and the electronic device is configured to present a first prompt, the first prompt being configured to instruct a user to avoid touching a target area of ​​the electronic device during the second time, the second radiator being located in the target area.

[0046] In combination with the second aspect, in some implementations of the second aspect, at the first time, the electronic device is in a non-earpiece mode; at the second time, the electronic device is in an earpiece mode.

[0047] In combination with the second aspect, in some implementations of the second aspect, the first prompt is a voice prompt.

[0081] The following explains the terms that may appear in the embodiments of the present application.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] Component / device: includes at least one of lumped component / device and distributed component / device.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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 regarded as a monopole antenna with a ground path added. 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, Planar Inverted FAntenna). In one embodiment, the sheet radiator may be implemented by a planar conductor (such as a conductive sheet or a conductive coating, etc.). In one embodiment, the sheet radiator may include a conductive sheet, such as a copper sheet, etc. In one embodiment, the sheet radiator may include a conductive coating, such as a silver paste, etc. 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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 electronic components, and the tuning circuit may be an electronic component 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.

[0099] 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.

[0100] 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).

[0101] 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).

[0102] 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).

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] Resonance / resonance 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 frequency corresponding to the strongest resonance point is the center frequency point frequency. The return loss characteristic of the center frequency can be 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.

[0109] Resonant frequency band: The range of the resonant frequency is the resonant frequency band. The return loss characteristic of any frequency point in the resonant frequency band can be less than -6dB or -5dB.

[0110] 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.

[0111] 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.

[0112] 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:

[0113]

[0114] Where L is the physical length and λ is the wavelength of the electromagnetic wave.

[0115] 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.

[0116] 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.

[0117] Antenna system efficiency (total efficiency): refers to the ratio of input power to output power at the antenna port.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] Beamwidth: This refers to the range of angles within a first angle range relative to the top of the electronic device (e.g., the z-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 30°, the antenna is considered to have a wide beam and exhibit good radiation characteristics within this angle range.

[0126] 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.

[0127] 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.

[0128] Antenna polarization direction: 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).

[0129] 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, etc. "Ground" can be used for grounding components in an electronic device. In one embodiment, "ground" can be the grounding layer of a circuit board of an electronic device, or it can be the grounding plate formed by the middle frame of the electronic device, or the grounding metal layer formed by the metal film under the screen. In one embodiment, the circuit board can be a printed circuit board (PCB), such as an 8-layer, 10-layer, or 12 to 14-layer board having 8, 10, 12, 13, or 14 layers of conductive material, or an element separated and electrically insulated by a dielectric layer or insulating layer such as fiberglass, polymer, etc. In one embodiment, the circuit board includes a dielectric substrate, a grounding layer, and a routing layer, and the routing layer and the grounding layer are electrically connected through vias. In one embodiment, components such as a display, touch screen, input buttons, transmitter, processor, memory, battery, charging circuit, and system-on-chip (SoC) structures can be mounted on or connected to a circuit board, or electrically connected to a trace layer and / or ground layer in the circuit board. For example, a radio frequency source can be located on a trace layer.

[0130] 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.

[0131] Grounding refers to coupling to the ground / floor in any manner. In one embodiment, grounding can be achieved through physical grounding, such as physical grounding at a specific location on the frame using a portion of the midframe's structural components (or referred to as a physical ground). In one embodiment, grounding can be achieved through device grounding, such as through a series or parallel connection of a capacitor, inductor, or resistor (or referred to as a device ground).

[0132] The technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0133] like Figure 1 As shown, the electronic device 10 may include: a cover 13, a display / module 15, a printed circuit board (PCB) 17, a middle frame 19, and a rear cover 21. It should be understood that in some embodiments, the cover 13 may be a glass cover, or may be replaced with a cover made of other materials, such as a PET (Polyethylene terephthalate) material cover.

[0134] 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.

[0135] 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.

[0136] The middle frame 19 mainly supports the entire device. Figure 1PCB 17 is shown as being located between the middle frame 19 and the back cover 21. It should be understood that, in one embodiment, PCB 17 may also be located between the middle frame 19 and the display module 15, and this is not a limitation in the present embodiment. The printed circuit board PCB 17 may be made of a flame-resistant material (FR-4) dielectric board, a Rogers dielectric board, a hybrid of Rogers and FR-4, or the like. FR-4 is a designation for a grade of flame-resistant material, and Rogers dielectric board is a high-frequency board. PCB 17 carries electronic components, such as radio frequency chips. In one embodiment, a metal layer may be provided on PCB 17. This metal layer may be used to ground the electronic components carried on PCB 17, as well as other components, such as a bracket antenna or a frame antenna. This metal layer may be referred to as a floor, ground plane, or grounding layer. In one embodiment, this metal layer may be formed by etching metal from the surface of any dielectric board in PCB 17. In one embodiment, this metal layer for grounding may be provided on the side of PCB 17 near the middle frame 19. In one embodiment, the edge of the printed circuit board PCB 17 can be considered the edge of its ground layer. In one embodiment, the metal middle frame 19 can also be used to ground the above components. The electronic device 10 can also have other floors / ground planes / ground layers, as described above, and will not be repeated here.

[0137] 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.

[0138] The electronic device 10 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.

[0139] The electronic device 10 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 10. The frame 11 may have four sides surrounding the display module 15 to help secure the display module 15.

[0140] 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 10, and is suitable for use in industrial designs (IDs) 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 10 and is generally referred to as a frame antenna.

[0141] 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 10. 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 10, 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.

[0142] It should be understood that there may be an insulating gap on the frame 11, and the conductive part of the frame between the two insulating gaps or the insulating gap and the grounding point serves as a radiator, thereby forming a frame antenna. Specifically, when the frame 11 is formed of a conductive material such as metal, the insulating gap can be understood as a gap in the frame 11 filled with a non-metallic material (insulating material). In this case, the gap is visible on the exterior surface. When the outer surface of the frame 11 is a non-conductive material, the insulating gap can be understood as a gap formed between two sections of 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.

[0143] exist Figure 1 The following embodiments are described using the example of a metal frame (conductive frame) and a visible slit on the exterior surface (an insulating gap visible on the exterior surface) as the frame 11 of the electronic device 10. 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 10 is a non-metallic frame (with an invisible slit on the exterior surface). For the sake of brevity, these details will not be repeated.

[0144] 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 10. 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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 10, wherein the frame 11, PCB 17, etc. of the electronic device can be grounded through electrical connection with the middle frame.

[0149] The antenna of the electronic device 10 can also be arranged in the housing, such as a bracket antenna, a millimeter wave antenna, etc. ( Figure 1 (not shown). The clearance of the antenna arranged in the shell can be obtained by the slits / openings on any one of the middle frame, and / or the frame, and / or the back cover, and / or the display screen, or by the non-conductive gaps / apertures formed between any of them. The clearance setting of the antenna can ensure the radiation characteristics of the antenna. It should be understood that the clearance of the antenna can be a non-conductive area formed by any conductive components in the electronic device 10, and the antenna radiates signals to the external space through the non-conductive area. In one embodiment, the antenna 40 can be in the form of an antenna based on a flexible printed circuit (FPC), an antenna based on laser direct structuring (LDS), or a microstrip disk antenna (MDA). In one embodiment, the antenna can also adopt a transparent structure embedded in the screen of the electronic device 10, so that the antenna is a transparent antenna unit embedded in the screen of the electronic device 10.

[0150] Figure 1 Only some components of the electronic device 10 are schematically shown, and the actual shapes, sizes and structures of these components are not affected by the present invention. Figure 1 limited.

[0151] 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.

[0152] First, by Figure 2 and Figure 3 To introduce this application, two antenna modes will be involved. Among them, Figure 2 This is a schematic diagram of the common mode structure of an antenna provided in this application and the corresponding current and electric field distribution. Figure 3 This is a schematic diagram of the structure of the differential mode of another antenna provided in this application and the corresponding current and electric field distribution. Figure 2 and Figure 3 The antenna radiator is open at both ends, and its common mode and differential mode can be called line common mode mode and line differential mode mode respectively.

[0153] 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.

[0154] 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.

[0156] Figure 2 (a) in the figure 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 grounded, 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).

[0157] 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 .

[0158] Figure 2 (b) shows the current and electric field distribution of antenna 40. Figure 2 As shown in (b), 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. Figure 2 As shown in (b), the current at the feeder 42 is distributed in the same direction. Based on the current distribution in the feeder 42, Figure 2 The feeding shown in (a) of FIG. 4 is called line CM feeding. Based on the fact that the current is distributed in opposite directions on both sides of the connection between the radiator and the feeding line 42, Figure 2 The antenna mode shown in (b) can be called a linear CM mode (also referred to as a CM mode for short, for example, for a linear antenna, the CM mode refers to a linear CM mode). Figure 2 The current and electric field shown in (b) can be called the current and electric field in the line CM mode, respectively.

[0159] The current is stronger at the middle position 41 of the antenna 40 (the current is stronger near the middle position 41 of the antenna 40), and weaker at both ends of the antenna 40, such as Figure 2 As shown in (b) in FIG. 4 , the electric field is weak at the middle position 41 of the antenna 40 and is strong at both ends of the antenna 40 .

[0160] 2. Line differential mode (DM) mode

[0161] like Figure 3 (a) shows that the left and right ends of the two radiators of antenna 50 are open, and a feed circuit is connected at the center 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 51 can be the geometric center of antenna 50 or the gap formed between the radiators.

[0162] 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°.

[0163] Figure 3 (b) shows the current and electric field distribution of antenna 50. Figure 3 As shown in (b), the current is distributed in the same direction on both sides of the middle position 51 of the antenna 50, for example, in an anti-symmetrical distribution; the electric field is distributed in opposite directions on both sides of the middle position 51. Figure 3 As shown in (b) in FIG, the current at the feeder 52 presents a reverse distribution. Based on the reverse distribution of the current at the feeder 52, Figure 3 The feeding shown in (a) can be called line DM feeding. Based on the fact that the current is distributed in the same direction on both sides of the connection between the radiator and the feeding line 52, Figure 3 The antenna mode shown in (b) can be called a linear DM mode (can also be simply referred to as a DM mode. For example, for a linear antenna, the DM mode refers to a linear DM mode). Figure 3 The current and electric field shown in (b) can be called the current and electric field in the line DM mode, respectively.

[0164] The current is stronger at the middle position 51 of the antenna 50 (the current is stronger near the middle position 51 of the antenna 50), and weaker at both ends of the antenna 50, such as Figure 3 As shown in (b) in FIG. , the electric field is weak at the middle position 51 of the antenna 50 and is strong at both ends of the linear antenna 50 .

[0165] It should be understood that the antenna radiator can be understood as a metal structure that generates radiation, and the number of the metal structure can be one, such as Figure 2 As shown, or, it can be two pieces, such as Figure 3 As shown, it can be adjusted according to actual design or production needs. For example, for the line CM mode, it can also be Figure 3 As shown, two radiators are used, and the two ends of the two radiators are arranged opposite to each other with a gap between them. A symmetrical feeding method is adopted at the two ends close to each other. For example, the same feed source signal is fed into the two ends close to each other, and the same Figure 2 The antenna structure shown in the figure has a similar effect. Correspondingly, for the line DM mode, it can also be Figure 2 As shown in the figure, a radiator is used, two feeding points are set in the middle of the radiator and an antisymmetric 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 respectively, the same power can be obtained. Figure 3 The antenna structure shown has a similar effect.

[0166] 3. Line CM-DM mode

[0167] above Figure 2 and Figure 3 The figures show the line CM mode and line DM mode generated by different feeding methods when both ends of the radiator are open.

[0168] When the antenna is fed in an asymmetric manner (the feeding point is offset from the middle of the radiator, including side feeding or offset feeding), or the grounding point of the radiator (where it is coupled with the floor) is asymmetric (the grounding point is offset from the middle of the radiator), the antenna can simultaneously generate the first resonance and the second resonance, corresponding to the line CM mode and the line DM mode, respectively. For example, the first resonance corresponds to the line CM mode, and the current and electric field distribution are as follows: Figure 2 The second resonance corresponds to the line DM mode, and the current and electric field distribution are shown in (b). Figure 3 As shown in (b) in .

[0169] Figure 4 This is a schematic diagram of a satellite communication usage scenario provided in an embodiment of the present application.

[0170] like Figure 4 As shown, 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).

[0171] However, during satellite communications, the antenna's radiation characteristics can change due to the human body's influence on the way the user holds the device. For example, the antenna's maximum radiation direction can deviate from the target radiation direction (e.g., toward the top of the device), reducing gain and radiation efficiency. In this case, the device and the communication satellite cannot maintain a good alignment, resulting in poor communication quality or even dropped calls, significantly impacting the user's communication experience.

[0172] 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 10, 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 10 and the communication satellite.

[0173] This application provides an electronic device comprising a first antenna and a second antenna. The operating frequency bands of the first antenna and the second antenna both include transmit frequencies within the satellite communication frequency band. The electronic device can switch between the first and second antennas based on different user gripping positions, thereby enhancing the user's satellite communication experience.

[0174] 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).

[0175] Figure 5 Schematic diagram of an electronic device 10 provided in an embodiment of the present application.

[0176] like Figure 5 As shown, the electronic device 10 includes a frame 11 , a first antenna 301 , a second antenna 302 , and a base 300 .

[0177] At least a portion of the frame 11 is spaced apart from the floor 300. The frame 11 includes a first position 201 and a second position 202. The frame 11 has an insulating gap at the first position 201 or is coupled to the floor 300. The frame 11 has an insulating gap at the second position 202 or is coupled to the floor 300.

[0178] The frame 11 includes a first side 131 and a second side 132 intersecting the first side 131 at an angle. The length of the first side 131 is shorter than the length of the second side 132. The first position 201 and the second position 202 are located on the first side 131. In one embodiment, the first side 131 can be understood as a short side of the electronic device 10.

[0179] It should be understood that the first side 131 can be the top side or the bottom side of the electronic device 10. For simplicity, the description will be given using the example where the first side 131 is the top side of the electronic device 10. The top side / bottom side of the electronic device 10 can be understood as the top / bottom side in normal use, for example, the top / bottom side of a mobile phone under the user interface (GUI) of the desktop.

[0180] When the electronic device 10 is a foldable electronic device including multiple housings, the first side 131 can be understood as the short side of the electronic device 10 when in a folded state, or the short side when in a flattened state. For example, in a large folding type electronic device (which can be understood as an electronic device that can still display a desktop user interface in the folded state), the first side 131 can be understood as the short side of the electronic device 10 when in a folded state. For another example, in a small folding type electronic device (which can be understood as an electronic device that can only display a desktop user interface in the flattened state), the first side 131 can be understood as the short side of the electronic device 10 when in a flattened state.

[0181] The electronic device 10 further includes a first antenna 301 and a second antenna 302 .

[0182] The first antenna 301 includes a first radiator 210. The first radiator 210 includes a conductive portion of the frame 11 between the first position 201 and the second position 202. At least a portion of the first radiator 210 is spaced apart from the floor 300.

[0183] The second antenna 302 includes a second radiator 220. The second radiator 220 includes a first grounding point 221, and the first grounding point 221 is coupled to the floor 300. At least a portion of the second radiator 220 is spaced apart from the floor 300.

[0184] In one embodiment, the second radiator 220 is attached to the back cover 21 of the electronic device 10 .

[0185] It should be understood that the second radiator 220 being attached to the back cover 21 of the electronic device 10 can be understood as the second radiator 220 being located on the surface of the back cover, or being disposed on the surface of the back cover via other structural members. Alternatively, the second radiator 220 being attached to the back cover 21 of the electronic device 10 can be understood as the second radiator 220 being disposed in close proximity to the back cover 21 in the electronic device 10. "Close proximity" can be understood, for example, to mean that the distance between the second radiator 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 220 can be located on one side of the plane of the back cover 21.

[0186] In one embodiment, the distance (eg, maximum distance) between the first radiator 210 and the second radiator 220 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 .

[0187] It should be understood that the first radiator 210 and / or the second radiator 220 can be located in the upper half of the electronic device 10 (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 10 has good communication quality with the communication satellite.

[0188] 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 10 may perform satellite communication via the first antenna 301 and / or the second antenna 302 .

[0189] 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).

[0190] 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.

[0191] In one embodiment, when the first antenna 301 and / or the second antenna 302 operate 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 10 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 operate 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 10 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 10 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.

[0192] The electronic device 10 further includes a first feeding circuit 231 .

[0193] The first feeding circuit 231 is used to transmit radio frequency signals in a first frequency band, where the first frequency band includes a transmitting frequency band in a satellite communication frequency band.

[0194] It should be understood that in the embodiment of the present application, the feed circuit can be understood as an RF channel of the radio frequency chip (RFIC) in the electronic device 10, 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 231 is used to generate an RF signal in a first frequency band that is fed into the antenna.

[0195] 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).

[0196] The first radiator 210 includes a first feeding point 211 . The second radiator 220 includes a second feeding point 212 . The first feeding circuit 231 is coupled to the first feeding point 211 , and the first feeding circuit 231 is coupled to the second feeding point 212 .

[0197] In one embodiment, the electronic device 10 further includes a first common port of a first switch 241 coupled to the first feeding circuit 231 , a first connection port of the first switch 241 coupled to the first feeding point 211 , and a second connection port of the first switch 241 coupled to the second feeding point 212 .

[0198] In one embodiment, at a first time, the electronic device 10 performs satellite communication in a first frequency band through the first antenna 301 . For example, the electronic device 10 sends a signal to a communication satellite through the first antenna 301 .

[0199] In one embodiment, when the electronic device 10 performs satellite communication and is in a non-earpiece mode, the first feeding circuit 231 feeds a radio frequency signal of the first frequency band to the first feeding point 211 (for example, the first common port of the first switch 241 is connected to the first connection port of the first switch 241), and the electronic device 10 performs satellite communication in the first frequency band through the first antenna 301. For example, the electronic device 10 sends a signal to the communication satellite through the first antenna 301.

[0200] It should be understood that in the above embodiment, when the electronic device 10 performs satellite communication and is in the non-earpiece mode, the time can be considered as the first time.

[0201] In one embodiment, at the second time, the electronic device 10 performs satellite communication in the first frequency band via the second antenna 302 . For example, the electronic device 10 sends a signal to a communication satellite via the second antenna 302 .

[0202] In one embodiment, when the electronic device 10 performs satellite communication and is in handset mode, the first feeding circuit 231 feeds a radio frequency signal of the first frequency band to the second feeding point 212 (for example, the first common port of the first switch 241 is connected to the second connection port of the first switch 241), and the electronic device 10 performs satellite communication in the first frequency band through the second antenna 302. For example, the electronic device 10 sends a signal to the communication satellite through the second antenna 302.

[0203] It should be understood that in the above embodiment, when the electronic device 10 is performing satellite communication and is in the handset mode, this time can be considered as the second time. For the sake of simplicity, the embodiments of this application mainly use the first time in the non-handset mode and the second time in the handset mode as an example. In actual production or application, the first time and the second time can also include other times unrelated to the handset mode or the non-handset mode, and can be designed according to actual needs.

[0204] It should be understood that the electronic device 10 being in the handset mode can be understood as the user conducting satellite communication (e.g., conducting a call via satellite, including a voice service call or a data service call) through the handset (receiver). For example, while the electronic device 10 is conducting satellite communication (e.g., a satellite call), the user taps the handset mode on the display screen. Alternatively, while the electronic device 10 is conducting satellite communication (e.g., a satellite call), a sensor (e.g., a proximity light sensor) senses that a human body is approaching the handset, and the call mode is changed to the handset mode.

[0205] The electronic device 10 being in a non-earpiece mode (e.g., hands-free mode or Bluetooth mode) can be understood as the user conducting satellite communication (e.g., satellite call) through the speaker. For example, while the electronic device 10 is conducting satellite communication (e.g., satellite call), the user taps the non-earpiece mode (e.g., hands-free mode or Bluetooth mode) on the display screen. Alternatively, while the electronic device 10 is conducting satellite communication (e.g., satellite call), a sensor (e.g., a proximity light sensor) senses that a human body is moving away from the earpiece, and the call mode is changed to a non-earpiece mode (e.g., hands-free mode or Bluetooth mode).

[0206] According to an embodiment of the present application, when conducting satellite communications (eg, satellite calls), the radiation characteristics of the antenna may change to a certain extent due to the influence of the human body when the user holds the electronic device 10 in different ways.

[0207] When the user uses the handset mode for satellite communication, the user's head is close to the handset, and the electronic device 10 performs satellite communication (for example, transmits signals to a communication satellite in the first frequency band) via the second antenna 302. Because the second antenna 302 is attached to the back cover of the electronic device 10, when the user holds the electronic device 10 in the handset mode, satellite communication (for example, transmitting signals to a communication satellite in the first frequency band) via the second antenna 302 will have better communication performance.

[0208] When the user uses a non-earpiece mode (e.g., hands-free mode or Bluetooth mode) for satellite communication, the user's head is away from the earpiece, and the electronic device 10 uses the first antenna 301 to perform satellite communication (e.g., transmit signals to a communication satellite in the first frequency band). Because the first radiator 210 of the first antenna 301 is located on the short side of the electronic device 10, when the user holds the electronic device 10 in the non-earpiece mode (e.g., hands-free mode or Bluetooth mode), the electronic device 10 uses the first antenna 301 to perform satellite communication (e.g., transmit signals to a communication satellite in the first frequency band) with better communication performance.

[0209] It should be understood that when the user uses the handset mode for satellite communication, since the handset is located close to the first radiator 210 (such as Figure 8As shown, the earpiece is located between the display screen 15 and the first side 131 of the frame 11. The earpiece is close to the first radiator 210 (for example, the minimum distance is less than 3 mm). The user's head is close to the earpiece, which significantly affects the radiation characteristics of the first antenna 301. Since the second antenna 302 is located on one side of the back cover of the electronic device 10 and is farther away from the user, the radiation characteristics of the second antenna 302 are less affected.

[0210] In one embodiment, the second radiator 220 may be located on the inner side of the back cover 21 (close to the PCB 17), as shown in FIG. Figure 6 As shown. In one embodiment, the second radiator 220 can be located between the back cover 21 and the PCB 17. In one embodiment, the electronic device 10 can further include a bracket 251, and the second radiator 220 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 220.

[0211] It should be understood that when the second radiator 220 is located inside the electronic device 10 , since the second radiator 220 is not located on the exterior surface of the electronic device 10 , a more flexible layout is provided.

[0212] In one embodiment, the second radiator 220 may be located outside the back cover 21 (away from the PCB 17), as shown in FIG. Figure 7 In one embodiment, the second radiator 220 may be a decorative piece (deco) of the camera module 252 of the electronic device 10 , and the decorative piece may be located on the outer surface of the camera module 252 and surround the camera module 252 .

[0213] It should be understood that when the second radiator 220 is arranged on the outside of the electronic device 10, 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).

[0214] In one embodiment, the frame 11 has a first insulating gap and a second insulating gap, respectively, at the first position 201 and the second position 202. In one embodiment, the distance between the first feeding point 211 and the first position 201 (the length of the frame 11 between the first feeding point 211 and the first position 201) and the distance between the first feeding point 211 and the second position 202 (the length of the frame 11 between the first feeding point 211 and the second position 202) are different.

[0215] 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 the width of the gaps on the frame in the embodiments of the present application can be within the above ranges, and for the sake of brevity, they will not be detailed here. The "width of the insulating gap" should be understood as the dimension in the direction extending between two sections of conductive material (e.g., two radiators).

[0216] In one embodiment, the first radiator 210 may be used to generate a first resonance, and a resonance frequency band of the first resonance includes the above-mentioned first frequency band.

[0217] It should be understood that the first resonance is generated 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 10 (the direction in which the first radiator 210 is away from the floor, e.g., the z-direction). In contrast, the directional pattern generated by the linear CM mode, because the current flowing into the floor 300 is strong 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 10 (the direction in which the first radiator 210 is away from the floor, e.g., the z-direction).

[0218] 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 210 extends in a straight line, under the action of the same-direction current, the conductor loss and dielectric loss are both small, and the efficiency (e.g., radiation efficiency) of the first antenna is high. However, due to the opposite 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.

[0219] In one embodiment, both ends of the first radiator 210 are open, and the first radiator 210 can operate in a half-wavelength mode. The electrical length of the first radiator 210 is half of the first wavelength, and the first wavelength is the wavelength corresponding to the first resonance generated by the radiator 210. The wavelength corresponding to the first resonance can be understood as the wavelength corresponding to the resonance point of the first resonance, or the wavelength corresponding to the center frequency of the first resonance frequency band. It should be understood that the above wavelengths are all vacuum wavelengths. Due to the certain conversion relationship between dielectric wavelengths and vacuum wavelengths, the above vacuum wavelengths can also be converted to dielectric wavelengths.

[0220] In one embodiment, the first radiator 210 may further include a grounding point, such as Figure 9 The first radiator 210 is coupled to the floor 300 at a grounding point.

[0221] In one embodiment, the grounding point may be located in the central area of ​​the first radiator 210 . The central area may be understood as an area within 5 mm from the center of the first radiator 210 . The lengths of the first radiators 210 on both sides of the center are the same.

[0222] It should be understood that by increasing the structural symmetry of the antenna 200 , the antenna 200 can have better communication performance.

[0223] In one embodiment, grounding can be achieved at the grounding point by a grounding piece, and the width of the connection between the grounding piece and the frame 11 is greater than or equal to 1 mm and less than or equal to 20 mm.

[0224] It should be understood that when the first radiator 210 is coupled to the floor 300 at the grounding point, the first radiator 210 can generate a second resonance in a line CM mode. The second resonance can be used to improve the radiation characteristics (e.g., radiation efficiency) of the first antenna 301 in the resonant frequency band of the first resonance. In one embodiment, the resonant point frequency of the first resonance can be higher than the resonant point frequency of the second resonance. The ratio between the resonant point frequency of the first resonance and the resonant point frequency of the second resonance can be greater than or equal to 1.1 and less than or equal to 1.5. In one embodiment, the frequency difference between the resonant point frequency of the first resonance and the resonant point frequency of the second resonance can be greater than or equal to 100 MHz and less than or equal to 500 MHz.

[0225] In one embodiment, when the grounding element includes at least a portion of the central area of ​​the first radiator 210 , the grounding point can be considered to be located in the central area of ​​the first radiator 210 .

[0226] In one embodiment, the second radiator 220 may be in any shape. In one embodiment, the second radiator 220 may be in a ring shape, such as Figure 5 For example, the second radiator 220 may be a decorative piece of the camera module 252 of the electronic device 10. In one embodiment, the second radiator 220 may be in the form of a sheet, such as Figure 9 shown.

[0227] It should be understood that the second radiator 220 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 220, which can be determined based on actual production or design and will not be described in detail.

[0228] In one embodiment, the second radiator 220 may form a structure similar to a patch antenna.

[0229] 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).

[0230] In one embodiment, the second radiator 220 can be used to generate a third resonance and a fourth resonance. The resonance point frequency of the third resonance is lower than the resonance point frequency of the fourth resonance, and the ratio of the resonance point frequency of the fourth resonance to the resonance point frequency of the third resonance is 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 third resonance and less than the resonance point frequency of the fourth resonance.

[0231] In one embodiment, the second radiator 220 further includes a second grounding point 222, at which the second radiator 220 is coupled to the floor 300. In one embodiment, the second radiator 220 includes a first centerline, with the second feed point 212 and the center (e.g., geometric center) of the second radiator 220 located on the first centerline. The first centerline divides the second radiator 220 into a first portion and a second portion, with the first grounding point 221 located in the first portion and the second grounding point 222 located in the second portion. It should be understood that when the second radiator 220 is annular or circular, the center can be understood as the center of the circle; when the second radiator 220 is a quadrilateral, the center can be understood as the intersection of the diagonals; and when the second radiator 220 has other irregular shapes, the center can be understood as the center of gravity.

[0232] It should be understood that the third resonance may be generated by the CM mode of the patch antenna, and the fourth resonance may be generated by the DM mode of the patch antenna.

[0233] 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).

[0234] like Figure 10 As shown in (a) in the figure, in the CM mode of the patch antenna, the current on the second radiator 220 is reversed on both sides of the virtual ground line (the first ground point 221 and the second ground point 222 are located on the virtual ground line) (when the second radiator 220 includes only one ground point, it can be understood as the side of the ground point close to the second feeding point 212 and the side away from the second feeding point 212).

[0235] like Figure 10As shown in (b) in FIG, when the second radiator is ring-shaped, in the CM mode, the current on the second radiator 220 on both sides of the first grounding point 221 is reversed, the current on the second radiator 220 on both sides of the second grounding point 222 is reversed, and the current on the second radiator 220 between the first grounding point 221 and the second grounding point 222 is reversed.

[0236] like Figure 10 As shown in (c) in FIG. 5 , in the CM mode of the patch antenna, the electric field between the second radiator 220 and the floor 300 is in the same direction on both sides of the virtual ground line.

[0237] like Figure 10 As shown in (d) in the figure, 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 10 (the 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 10 (the 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 10 (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%).

[0238] In the CM mode of the patch antenna, the electric field between the second radiator 220 and the floor 300 is in the same direction on both sides of the virtual ground line, but is partially reversed in the far field of the second radiator 220 (for example, this can be understood from the fact that the circumferential electric field shown by the curved arrow is partially reversed). Figure 10 As shown in (e) in FIG. 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 direction of the electronic device 10 (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 direction of the electronic device 10 (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).

[0239] like Figure 11 As shown in (a) in FIG. 5 , in the DM mode of the patch antenna, the current on the second radiator 220 is in the same direction on both sides of the virtual ground line.

[0240] like Figure 11 As shown in (b), when the second radiator is ring-shaped, in the DM mode, the currents on the second radiator 220 on both sides of the first grounding point 221 are in the same direction, the currents on the second radiator 220 on both sides of the second grounding point 222 are in the same direction, and the currents on the second radiator 220 between the first grounding point 221 and the second grounding point 222 are in opposite directions.

[0241] like Figure 11 As shown in (c) in FIG. 5 , in the DM mode of the patch antenna, the electric field between the second radiator 220 and the ground plane 300 is in opposite directions on both sides of the virtual ground line.

[0242] like Figure 11 As shown in (d) in FIG, 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 10. 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 10 (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 10 (direction from the top edge to the bottom edge, e.g., the negative direction of the z-direction).

[0243] In the DM mode of the patch antenna, the electric fields between the second radiator 220 and the floor 300 are in opposite directions on both sides of the virtual ground line, but are in the same direction in the far field of the second radiator 220 (for example, this can be understood from the fact that the circumferential electric fields shown by the curved arrows are substantially in the same direction). Figure 11 Therefore, the directional pattern generated by the second antenna is in the same direction as the electric field in the far field.

[0244] 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 is greater than the resonant point frequency of the third resonance and less than the resonant point frequency of the fourth resonance. In the first frequency band, the second antenna 302 radiates from both the CM mode and the DM mode of the patch antenna.

[0245] 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.

[0246] 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 10 has better communication performance.

[0247] In one embodiment, when the second radiator 220 is ring-shaped, the length difference between the second radiator 220 on both sides of the virtual ground line (the virtual ground line is the line connecting the first ground point 221 and the second ground point 222 ) is within 20%.

[0248] It should be understood that as the symmetry increases, the radiation characteristics of the second antenna 302 are better.

[0249] In one embodiment, the ratio of the fourth resonance frequency to the third 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.

[0250] 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 (for example, the proportion of the radiation pattern increases toward the top).

[0251] In one embodiment, the minimum distance between the first radiator 210 and the second radiator 220 is less than or equal to 20 mm. In one embodiment, the distance between the first radiator 210 and the second radiator 220 is less than or equal to 10 mm.

[0252] In one embodiment, the distance between the first feeding point 211 and the second feeding point 212 is less than or equal to 20 mm. In one embodiment, the distance between the first feeding point 211 and the second feeding point 212 is less than or equal to 10 mm.

[0253] 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 211 and the second feeding point 212 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 210 and the center of the area where the second metal part used to feed the second antenna 302 contacts the second radiator 220.

[0254] When the first radiator and the second radiator are both fed by indirect coupling, the distance between the first feeding point 211 and the second feeding point 212 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 210 on the first radiator 210 (along the extension direction perpendicular to the first radiator 210) 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 220 on the second radiator 220 (along the thickness direction of the electronic device 10).

[0255] When the first radiator and the second radiator are fed by electrical connection and indirect coupling respectively, the above embodiments may be referred to for corresponding understanding.

[0256] When the distance between the first feeding point 211 and the second feeding point 212 is close, the transmission line distance between the RF channel (first feeding circuit 231) and the feeding point (for example, the first feeding point 211 or the second feeding point 212) is short, and the loss of the RF signal output by the RF channel on the transmission path is small, which is beneficial to improving the radiation characteristics (for example, gain) of the antenna (the first antenna 301 or the second antenna 302).

[0257] In one embodiment, the electronic device 10 may further include a second feeding circuit 232, such as Figure 12 The second feeding circuit 232 is used to transmit radio frequency signals in a second frequency band, where the second frequency band includes a receiving frequency band in a satellite communication frequency band. In one embodiment, the second feeding circuit 232 is used to process radio frequency signals in the second frequency band received by the antenna.

[0258] In one embodiment, the second common port of the first switch 241 is coupled to the second feeding circuit 232 , the third connection port of the first switch 241 is coupled to the first feeding point 211 , and the fourth connection port of the first switch 241 is coupled to the second feeding point 212 .

[0259] It should be understood that when the electronic device 10 performs satellite communication, it can communicate with the communication satellite through an antenna within the electronic device 10. In this case, the antenna can be loaded with different electronic components at different times 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 at different times.

[0260] In one embodiment, the first feeding point 211 on the first radiator 210 (or the second feeding point 212 on the second radiator 220) receives the first RF signal fed by the first feeding circuit 231. 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.

[0261] In one embodiment, the first feed point 211 on the first radiator 210 (or the second feed point 212 on the second radiator 220) receives a second RF signal transmitted by a communications satellite and transmits it to the second feed circuit 232. The second RF signal corresponds to the satellite system's receiving frequency band. The first antenna 301 (or the second antenna 302) then operates within the satellite system's receiving frequency band to receive signals from the communications satellite. Typically, the radiator switches between receiving the second RF signal at the first feed point 211 and the second feed point 212 via a first switch coupled to the feed point.

[0262] In one embodiment, at a first time / time period, the first feeding point 211 (or the second feeding point 212) feeds a first radio frequency signal, and the resonance frequency band generated by the first radiator 210 (or the second radiator 220) includes a first frequency band, and the first frequency band may include a transmission frequency band in a satellite communication frequency band.

[0263] In one embodiment, at a first time / time period, the first feeding point 211 (or the second feeding point 212) communicates with the second RF signal sent by the satellite, and the resonant frequency band of the resonance generated by the first radiator 210 (or the second radiator 220) includes a second frequency band, and the second frequency band may include a receiving frequency band in the satellite communication frequency band.

[0264] It should be understood that Figure 12 In the illustrated electronic device 10, the electronic device 10 is coupled to the first connection port or the second connection port via the first common port of the first switch 241. The electronic device 10 can perform satellite communication in the first frequency band (e.g., transmit signals to a communication satellite in the first frequency band) via one of the first antenna 301 and the second antenna 302. The electronic device 10 is coupled to the third connection port or the fourth connection port via the second common port of the first switch 241. The electronic device 10 can perform satellite communication in the second frequency band (e.g., receive signals transmitted by a communication satellite in the second frequency band) via one of the first antenna 301 and the second antenna 302.

[0265] For the sake of brevity, Figure 12 In the electronic device 10 shown, only the first switch 241 is a double-pole double-throw (DPDT) as an example for illustration. In actual production or design, it can be replaced. For example, the first switch 241 can be a double-pole multi-throw (DPXT) or a multi-pole multi-throw (XPXT) or a combination of multiple single-pole single-throw (SPST). The embodiment of the present application does not limit this, and the switches described in the embodiment of the present application can be understood accordingly.

[0266] 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).

[0267] In one embodiment, the first antenna 301 may further include a second feeding circuit 232, and the second antenna 302 may further include a third feeding circuit 233. Figure 13 The second feeding circuit 232 and the third feeding circuit 233 are used to transmit radio frequency signals of the second frequency band. In one embodiment, the second feeding circuit 232 and the third feeding circuit 233 are used to process radio frequency signals of the second frequency band received by the antenna.

[0268] In one embodiment, the second feeding circuit 232 is coupled to the first feeding point 211 , and the third feeding circuit 233 is coupled to the second feeding point 212 .

[0269] It should be understood that Figure 13 In the illustrated electronic device 10, the electronic device 10 is coupled to the first connection port or the second connection port via the first common port of the first switch 241. The electronic device 10 can perform satellite communication in the first frequency band (e.g., transmit signals to a communication satellite in the first frequency band) via one of the first antenna 301 and the second antenna 302. The electronic device 10 can also perform satellite communication in the second frequency band (e.g., receive signals transmitted by a communication satellite in the second frequency band) via the first antenna 301 and the second antenna 302 simultaneously.

[0270] The signals transmitted by the communication satellite received by the first antenna 301 and the second antenna 302 in the second frequency band can be superimposed by algorithms or other means, thereby enhancing the communication quality between the electronic device 10 and the communication satellite.

[0271] In one embodiment, the second antenna 302 may further include a first element 261, such as Figure 14 The second radiator 220 further includes a connection point 230 . The first element 261 is coupled between the connection point 230 and the floor 300 .

[0272] It should be understood that, in one embodiment, the first element 261 coupled between the floor 300 and the connection point 230 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. The first element 261 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 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. The first element 261 coupled between the floor 300 and the connection point 230 can increase the flexibility of adjusting the second antenna 302.

[0273] In one embodiment, the angle between the connection point 230 and the second feed point 212 is greater than or equal to 45°. In one embodiment, the angle between the connection point 230 and the second feed point 212 is greater than or equal to 90°. In one embodiment, the angle between the connection point 230 and the second feed point 212 is greater than or equal to 135°.

[0274] It should be understood that the angle between the connection point 230 and the second feed point 212 can be understood as the angle between the connection point 230 and the second feed point 212 relative to the geometric center of the second radiator 220. As the angle between the connection point 230 and the second feed point 212 increases, the adjustable range of the first element 261 further increases.

[0275] In one embodiment, the first element 261 may be a capacitor, or an element equivalent to a capacitor. In one embodiment, the equivalent capacitance value of the first element 261 may be less than or equal to 1 pF.

[0276] In one embodiment, the first element 261 may be an inductor, or an element equivalent to an inductor.

[0277] Figures 15 to 17 yes Figure 14 The simulation results of the second antenna 302 in the electronic device 10 are shown. Figure 15 yes Figure 14 The simulation results of the S parameters of the second antenna 302 in the electronic device 10 are shown. Figure 16 yes Figure 14 The figure shows simulation results of the radiation efficiency of the second antenna 302 of the electronic device 10 in the non-earpiece mode. Figure 17 yes Figure 14 The figure shows simulation results of the radiation efficiency of the second antenna 302 of the electronic device 10 in the handset mode.

[0278] It should be understood that for the sake of simplicity, the second antenna 302 operating in the first frequency band, which includes the transmit frequency band (1980 MHz-2010 MHz) in the Tiantong satellite system, is used as an example for description.

[0279] like Figure 15 As shown, the second antenna can resonate near 1.95 GHz and 2.05 GHz. The resonance near 1.95 GHz may correspond to the third resonance in the above embodiment, and the resonance near 2.05 GHz may correspond to the fourth resonance in the above embodiment.

[0280] It should be understood that Figure 15 The simulation results shown in the figure show S-parameters at two different frequencies (1.99 GHz and 2.05 GHz), which are roughly located near the resonance points of the first and second resonances. At the two frequencies shown (1.99 GHz and 2.05 GHz), the depths are -18.9 dB and -3.3 dB, respectively. The depths in the S-parameters may vary in actual simulation and debugging results, but it is generally believed that a depth above 3 dB is sufficient for communication.

[0281] like Figure 16 As shown, in the non-earpiece mode (for example, the user does not hold the electronic device 10 close to the head), in the first frequency band, the radiation efficiency is approximately -4.1 dB.

[0282] It should be understood that Figure 16 The simulation results graph shows the radiation efficiency at three different frequencies (2.0 GHz, 1.95 GHz, and 2.05 GHz). These frequencies are roughly located near the center frequency of the first frequency band, the resonance point of the first resonance, and the resonance point of the second resonance. At the three frequencies shown (2.0 GHz, 1.95 GHz, and 2.05 GHz), the radiation efficiency is -4.1 dB, -4.7 dB, and -5.6 dB, respectively. Actual simulation and debugging results may show different radiation efficiencies in the radiation efficiency curves. Generally, a value greater than -8 dB is considered sufficient for communication.

[0283] like Figure 17 As shown, in the handset mode (for example, the user holds the electronic device 10 close to the head, for example, in the beside head hand left (BHHL) model or the beside head hand right (BHHR) model), in the first frequency band, the radiation efficiency is approximately -6.7dB, a decrease of approximately 2.6dB.

[0284] It should be understood that Figure 17 In the graph of the simulation results shown, the radiation efficiency at the center frequency (2.0 GHz) of the first frequency band is shown.

[0285] Figure 14 Figures 18 to 20 yes Figure 14The directional pattern generated by the second antenna 302 in the electronic device 10 is shown. Figure 18 yes Figure 14 The second antenna 302 in the electronic device 10 generates a directional pattern in free space (FS). Figure 19 yes Figure 14 The second antenna 302 in the electronic device 10 is shown as generating a directional pattern on the left side of the human head and hand model. Figure 20 yes Figure 14 The second antenna 302 in the electronic device 10 is shown as generating a directional pattern on the right side of the human head and hand model.

[0286] like Figure 18 As shown, in free space, since the center frequency of the first frequency band is greater than the resonance point frequency of the third resonance and less than the resonance point frequency of the fourth resonance, in the first frequency band, the second antenna 302 generates radiation 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 positive direction of the z direction), which can better communicate with the communication satellite.

[0287] like Figure 19 and Figure 20 As shown, under the left human head and hand model or the right human head and hand model, the directional pattern generated by the second antenna has strong radiation in the top direction (for example, the positive direction of the z direction), which can better communicate with the communication satellite.

[0288] Figure 21 Schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0289] like Figure 21 As shown, the second antenna 302 may further include a second switch 242 and a plurality of elements. In one embodiment, the second antenna 302 may include a first element 261 and a second element 262 .

[0290] The second switch 242 is coupled between the connection point 230 and the floor 300. A plurality of elements (eg, a first element 261 and a second element 262) may be coupled between the second switch 242 and the floor 300 or between the second switch 242 and the connection point 230.

[0291] It should be understood that Figure 21 The electronic device 10 is shown with Figures 5 to 9 ,as well as Figures 12 to 14 The electronic device 10 shown differs only in the second switch 242 and the plurality of first elements 261 .

[0292] In one embodiment, the element coupled between the floor 300 and the connection point 230 may be used to switch the radiation characteristics (eg, the maximum radiation direction) of the second antenna 302 in the first frequency band.

[0293] It should be understood that Figures 5 to 9 ,as well as Figures 12 to 14 The electronic device 10 shown may include only one element (eg, first element 261). Figure 21 The electronic device 10 shown includes multiple elements (for example, a first element 261 and a second element 262). The equivalent capacitance value or equivalent inductance value of the element coupled between the connection point 230 and the floor 300 can be switched through the second switch 242, or the boundary condition of the connection point 230 can be switched through the second switch 242, for example, the connection point 230 is disconnected from the floor 300, or the connection point 230 is directly electrically connected to the floor 300 (without setting any elements), so that the frequency difference between the resonance point of the third resonance and the resonance point of the fourth resonance can be adjusted.

[0294] 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 first element 261 and the second radiator 220 are used to generate the third resonance 1 and the fourth resonance 1. The second element 262 and the second radiator 220 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.

[0295] Since the center frequency of the first frequency band can be relatively close to the resonance point of the third resonance or the resonance point of the fourth resonance, the radiation characteristics (e.g., the maximum radiation direction) of the second antenna 302 in the first frequency band can be adjusted, thereby achieving the switching of the radiation characteristics (e.g., the maximum radiation direction) of the second antenna 302 in the first frequency band.

[0296] In one embodiment, the element coupled between the floor panel 300 and the connection point 230 can be used to switch the operating frequency band of the second antenna 302 .

[0297] It should be understood that Figures 5 to 9 ,as well as Figures 12 to 14 The electronic device 10 shown may include only one element (eg, first element 261). Figure 21The electronic device 10 shown includes multiple components (e.g., a first component 261 and a second component 262). A second switch 242 can be used to switch the equivalent capacitance or inductance of the components coupled between the connection point 230 and the floor 300. Alternatively, the boundary conditions of the connection point 230 can be switched, for example, disconnecting the connection point 230 from the floor 300 or directly electrically connecting the connection point 230 to the floor 300 (without any components). This allows for adjustment of the resonant frequencies of the third and fourth resonances. For example, the first component 261 and the second radiator 220 are used to generate the third resonance 1 and the fourth resonance 1. The second component 262 and the second radiator 220 are used to generate the third resonance 2 and the fourth resonance 2. The center frequency of the first frequency band is less than the resonant frequency of the fourth resonance 1 and greater than the resonant frequency of the third resonance 1. The center frequency of the second frequency band is less than the resonant frequency of the fourth resonance 2 and greater than the resonant frequency of the third resonance 2. Switching the first component 261 and the second component 262 can switch the operating frequency band of the second antenna 302.

[0298] In one embodiment, when the electronic device 10 is not performing satellite communication, the second switch 242 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.

[0299] For the sake of brevity, Figure 21 The electronic device 10 is shown with Figures 5 to 9 ,as well as Figures 12 to 14 Similar parts of the electronic device 10 shown are not described one by one. For example, the similar parts include: the position of the first radiator 210, the position of the second radiator 220, information of the first frequency band; information of the second frequency band; the electronic device 10 sends a signal to the communication satellite through one of the first antenna 301 and the second antenna 302; the electronic device 10 receives the signal sent by the communication satellite through one of the first antenna 301 and the second antenna 302; the electronic device 10 receives the signal sent by the communication satellite through the first antenna 301 and the second antenna 302 at the same time; the mode of the second radiator 220; and so on.

[0300] Figure 22 Schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0301] like Figure 22 As shown, the second antenna 302 may include a third switch 243 , a fourth switch 244 , a fifth switch 245 , and a sixth switch 246 . The second radiator 220 further includes a third grounding point 223 and a fourth grounding point 224 .

[0302] The third switch 243 is coupled between the first grounding point 221 and the floor 300. The fourth switch 244 is coupled between the second grounding point 222 and the floor 300. The fifth switch 245 is coupled between the third grounding point 223 and the floor 300. The sixth switch 246 is coupled between the fourth grounding point 224 and the floor 300.

[0303] It should be understood that Figure 22 The electronic device 10 is shown with Figure 21 The electronic device 10 shown differs only in the third switch 243 , the fourth switch 244 , the fifth switch 245 and the sixth switch 246 .

[0304] exist Figure 21 The electronic device 10 shown may include a first grounding point 221 and a second grounding point 222 . The second radiator 220 is coupled to the floor 300 at the first grounding point 221 and the second grounding point 222 . No switch is provided between the grounding points and the floor 300 .

[0305] And in Figure 22 The electronic device 10 shown includes multiple switches corresponding to grounding points, each of which is coupled between the corresponding grounding point and the floor 300. The switches can be used to switch the boundary conditions of the corresponding grounding point, for example, disconnecting the corresponding grounding point from the floor 300 or directly connecting (coupling) the corresponding grounding point to the floor 300, thereby varying the current distribution on the second radiator 220 and adjusting the radiation characteristics of the second antenna 302 (for example, the direction of maximum radiation).

[0306] In one embodiment, the third grounding point 223 and the fourth grounding point 224 are located on both sides of the first feeding point 211 and the second feeding point 212 respectively.

[0307] In one embodiment, the distance between any two adjacent grounding points among the multiple grounding points (the length of the second radiator 220 between any two adjacent grounding points) is approximately one-quarter (e.g., one-quarter ± 10%) of the length of the second radiator 220. This makes it easier to adjust the current on the second radiator 220 and control the radiation characteristics of the second antenna 302 (e.g., the maximum radiation direction).

[0308] In one embodiment, when the first grounding point 221 and the second grounding point 222 are coupled to the floor 300 and the third grounding point 223 and the fourth grounding point 224 are disconnected from the floor 300, by adjusting the first element coupled to the connection point 230, the large radiation direction generated by the second antenna 302 can be moved in a direction perpendicular to the line segment between the first grounding point 221 and the second grounding point 222.

[0309] In one embodiment, when the first grounding point 221 and the second grounding point 222 are disconnected from the floor 300 and the third grounding point 223 and the fourth grounding point 224 are coupled to the floor 300, by adjusting the first element coupled to the connection point 230, the maximum radiation direction generated by the second antenna 302 can be moved in a direction perpendicular to the line segment between the third grounding point 223 and the fourth grounding point 224.

[0310] For the sake of brevity, Figure 22 The electronic device 10 is shown with Figure 21 Similar parts of the electronic device 10 shown are not described one by one. For example, the similar parts include: the position of the first radiator 210, the position of the second radiator 220, information of the first frequency band; information of the second frequency band; the electronic device 10 sends a signal to the communication satellite through one of the first antenna 301 and the second antenna 302; the electronic device 10 receives the signal sent by the communication satellite through one of the first antenna 301 and the second antenna 302; the electronic device 10 receives the signal sent by the communication satellite through the first antenna 301 and the second antenna 302 at the same time; the mode of the second radiator 220; and so on.

[0311] Figures 23 to 26 yes Figure 22 The directional pattern generated by the second antenna 302 in the electronic device 10 is shown. Figure 23 yes Figure 22 The second antenna 302 in the electronic device 10 is shown as generating a directional pattern when coupled to the floor 300 at the first ground point 221 and the second ground point 222 . Figure 24 yes Figure 22 The second antenna 302 in the electronic device 10 is shown as a directional pattern when coupled to the floor 300 at the first ground point 221 and the second ground point 222 . Figure 25 yes Figure 22 The second antenna 302 in the electronic device 10 is shown to generate a directional pattern when coupled to the floor 300 at the third ground point 223 and the fourth ground point 224 . Figure 26 yes Figure 22 The directional pattern of the second antenna 302 in the electronic device 10 when coupled with the floor 300 at the third ground point 223 and the fourth ground point 224 is shown.

[0312] like Figure 23 and Figure 24 As shown, when the first grounding point and the second grounding point are coupled to the floor and the third grounding point and the fourth grounding point are disconnected from the floor, adjusting the boundary conditions with the connection points (for example, the equivalent capacitance value or the equivalent inductance value of the first element) can move the maximum radiation direction generated by the second antenna in a direction perpendicular to the line segment between the first grounding point and the second grounding point (for example, the z direction).

[0313] like Figure 23 As shown, when the connection point is not coupled to the first element (the connection point is disconnected from the ground), the maximum radiation direction of the second antenna is toward the thickness direction of the electronic device (for example, the x direction).

[0314] like Figure 24 As shown, when the equivalent inductance of the first element coupled to the connection point (the equivalent inductance between the connection point and the floor) is 20 nH, the maximum radiation direction of the second antenna is toward the top direction of the electronic device (for example, the z direction).

[0315] like Figure 25 and Figure 26 As shown, when the first grounding point and the second grounding point are disconnected from the floor and the third grounding point and the fourth grounding point are coupled to the floor, adjusting the boundary conditions with the connection points (for example, the equivalent capacitance value or the equivalent inductance value of the first element) can make the maximum radiation direction generated by the second antenna move in a direction perpendicular to the line segment between the third grounding point and the fourth grounding point (for example, the y direction).

[0316] like Figure 25 As shown, when the branch between the connection point and the ground is electrically connected (the first element is not coupled between the connection point and the ground), the maximum radiation direction of the second antenna is toward the right side of the electronic device (for example, the positive direction of the y direction).

[0317] like Figure 26 As shown, when the equivalent inductance of the first element connected to the connection point (the equivalent inductance between the connection point and the floor) is 20nH, the maximum radiation direction of the second antenna is toward the left side of the electronic device (for example, the negative direction of the y direction).

[0318] Figure 27 Schematic diagram of another electronic device 10 provided in an embodiment of the present application.

[0319] like Figure 27 As shown, the second antenna 302 may further include a power division phase shifter 240 .

[0320] The second radiator 220 further includes a third feeding point 213. The first port of the power divider phase shifter 240 is coupled to the second connection port of the first switch 241, the second port of the power divider phase shifter 240 is coupled to the second feeding point 212, and the third port of the power divider phase shifter 240 is coupled to the third feeding point 213.

[0321] It should be understood that the power division phase shifter 240 can be used to distribute the power of the radio frequency signal generated by the second connection port of the first switch 241 from the first port and transmit it to the second port and the third port to achieve power division characteristics. In addition, the power division phase shifter 240 can also be used to adjust the phase of the radio frequency signal at the second port (second feeding point 212) and the third port (third feeding point 213) to achieve a phase shifting function. In one embodiment, the power of the radio frequency signal at the second port (second feeding point 212) and the third port (third feeding point 213) is approximately the same (for example, due to the different circuit paths between the second connection port of the first switch 241 and the second port (second feeding point 212) and the third port (third feeding point 213), there is partial power loss, so the power error within 15% can be considered to be approximately the same).

[0322] It should be understood that the power division phase shifter 240 can be understood as a circuit for realizing the above-mentioned functions. In one embodiment, the power division phase shifter 240 can be understood as a circuit including a power division phase shifter chip, and the circuit has the above-mentioned functions. In one embodiment, the power division phase shifter 240 can be understood as a circuit including a power divider chip and a phase shifter chip, and the circuit has the above-mentioned functions. In one embodiment, the power division phase shifter 240 can be understood as a circuit composed of microstrip lines / strip lines, and the circuit has the above-mentioned functions. The embodiments of the present application do not limit the structure of the power division phase shifter 240, which can be determined according to actual production or design. For the sake of brevity, it will not be described in detail one by one.

[0323] It should be understood that Figure 27 The electronic device 10 is shown with Figures 5 to 9 ,as well as Figures 12 to 14 The electronic device 10 shown differs only in the power division phase shifter 240 .

[0324] exist Figures 5 to 9 ,as well as Figures 12 to 14 In the electronic device 10 shown, the second radiator 220 includes only one feeding point (the second feeding point 212 ), and the second antenna 302 is fed with a radio frequency signal through the feeding point to generate the third resonance and the fourth resonance.

[0325] And in Figure 27 In the electronic device 10 shown, the second radiator 220 includes a second feeding point 212 and a third feeding point 213. The second antenna 302 is fed with RF signals of the same or different phases by the second feeding point 212 and the third feeding point 213 to generate the third and fourth resonances.

[0326] Therefore, in Figure 27In the electronic device 10 shown, the radiation characteristics (eg, maximum radiation direction) of the second antenna 302 in the first frequency band can be switched by controlling the phase difference between the RF signals fed into the second feeding point 212 and the third feeding point 213 .

[0327] In one embodiment, when the second radiator 220 is in a sheet shape, the second feeding point 212 and the third feeding point 213 are respectively located on both sides of a virtual ground line, and the virtual ground line is a line connecting the first ground point 221 and the second ground point 222 .

[0328] In one embodiment, the second feeding point 212 and the third feeding point 213 are symmetrical along the virtual ground line.

[0329] In one embodiment, when the second radiator 220 is annular, the second feeding point 212 and the third feeding point 213 divide the second radiator 220 into a third part and a fourth part, and the length L1 of the third part and the length L2 of the fourth part satisfy: L2×90%≤L1≤L2×120%.

[0330] It should be understood that as the structural symmetry of the second antenna 302 increases, the second antenna 302 has better radiation characteristics.

[0331] For the sake of brevity, Figure 27 The electronic device 10 is shown with Figures 5 to 9 ,as well as Figures 12 to 14 Similar parts of the electronic device 10 shown are not described one by one. For example, the similar parts include: the position of the first radiator 210, the position of the second radiator 220, information of the first frequency band; information of the second frequency band; the electronic device 10 sends a signal to the communication satellite through one of the first antenna 301 and the second antenna 302; the electronic device 10 receives the signal sent by the communication satellite through one of the first antenna 301 and the second antenna 302; the electronic device 10 receives the signal sent by the communication satellite through the first antenna 301 and the second antenna 302 at the same time; the mode of the second radiator 220; and so on.

[0332] Figure 28 and Figure 29 yes Figure 27 The directional pattern generated by the second antenna 302 in the electronic device 10 is shown. Figure 28 yes Figure 27 The directional pattern generated by the second antenna 302 in the electronic device 10 when the phase difference between the second feeding point 212 and the third feeding point 213 is 90° is shown.

[0333] Figure 29 yes Figure 27The directional pattern of the second antenna 302 in the electronic device 10 is shown when the phase difference between the second feeding point 212 and the third feeding point 213 is 270°.

[0334] like Figure 28 As shown, when the phase difference between the RF signal fed into the second feeding point and the phase between the RF signal fed into the third feeding point is 90°, the maximum radiation direction of the second antenna is toward the bottom direction of the electronic device (for example, the negative z direction).

[0335] like Figure 29 As shown, when the phase difference between the RF signal fed into the second feeding point and the phase between the RF signal fed into the third feeding point is 270°, the maximum radiation direction of the second antenna is toward the top direction of the electronic device (for example, the positive z direction).

[0336] Figure 30 Schematic diagram of a user interface (UI) of an electronic device 10 provided in an embodiment of the present application.

[0337] It should be understood that Figure 30 The user interface shown can be applied to the electronic device 10 shown in any of the above embodiments, and the embodiments of the present application do not limit this. The electronic device 10 can be used to present a first prompt, and the first prompt is used to instruct the user to avoid touching the target area of ​​the electronic device 10 at the above second time, wherein the above second radiator is located in the target area. In one implementation, at a first time, the electronic device 10 performs satellite communication in a first frequency band by a first antenna. At a second time, the electronic device 10 performs satellite communication in a first frequency band by a second antenna. In one embodiment, when the electronic device 10 performs satellite communication in the first frequency band via the second antenna, the electronic device 10 presents the first prompt. In one embodiment, the first prompt may appear at the second time, or at a time other than the first time and the second time.

[0338] In one embodiment, Figure 30 As shown, when the electronic device is performing satellite communication, in the handset mode (and / or before entering the handset mode), the electronic device 10 presents a first prompt 310. The first prompt is used to instruct the user not to touch the target area when holding the electronic device 10 at the second time. The second radiator can be located in the target area.

[0339] The target area can be understood as the area within 5 mm of the second radiator. It should be understood that when the user's mobile phone is close to or in contact with the second radiator, the radiation characteristics of the second antenna are reduced. When the user is conducting satellite communication in handset mode, the communication quality between the electronic device 10 and the communication satellite may deteriorate due to the reduced radiation characteristics of the second antenna.

[0340] In one embodiment, the first prompt 310 may be one or more of a picture prompt, a text prompt, and / or a voice prompt.

[0341] It should be understood that when a user performs satellite communication in handset mode, the user may be prompted in different ways not to touch the target area when holding the electronic device 10 .

[0342] For example, when the user clicks on the handset mode on the display screen, a first prompt including text type and / or picture type is displayed on the display screen of the electronic device 10, prompting the user not to touch the target area when holding the electronic device 10, such as Figure 30 As shown, the electronic device 10 may play a first voice prompt 310 through the earpiece to remind the user not to touch the target area when holding the electronic device 10. For another example, when a sensor (e.g., a proximity light sensor) of the electronic device 10 senses that a human body is close to the earpiece, the call mode is changed to the earpiece mode. In this case, the first voice prompt 310 may be played through the earpiece to remind the user not to touch the target area when holding the electronic device 10.

[0343] It should be understood that the electronic device 10 may present the first prompt 310 at different times of satellite communication. In one embodiment, the electronic device 10 presents the first prompt 310 at the second time. In one embodiment, the first prompt 310 is presented when the electronic device 10 is connected to the communication satellite, such as Figure 30 In one embodiment, when the electronic device 10 is successfully connected to the communication satellite, the user can select the handset mode for satellite communication. In response to the user clicking the handset mode, the electronic device 10 presents a first prompt 310, as shown in FIG. Figure 30 In one embodiment, when the user clicks on the satellite communication application and enters the satellite communication related graphical interface, a first prompt 310 is presented, prompting the user not to touch the target area when holding the electronic device 10 when subsequently using the handset mode.

[0344] In one embodiment, the second radiator includes a decorative piece of the camera module. The first prompt is used to instruct the user not to touch the area where the camera module is located when holding the electronic device 10, for example, Figure 7 In one embodiment, the first prompt is used to instruct the user not to touch the camera module when holding the electronic device 10.

[0345] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
