Description

Technical Field

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

[0002] Satellite communications use circularly polarized electromagnetic waves for signal transmission. With the development of technology, electronic devices such as mobile phones and tablets are pursuing thinness and lightness. Due to the thickness of electronic devices, the antennas used for satellite communications in electronic devices can only achieve linear polarization. Therefore, when electronic devices use linearly polarized antennas to receive circularly polarized electromagnetic waves emitted by satellite antennas, half of the energy will be lost due to polarization mismatch. Conversely, when electronic devices use linearly polarized antennas to transmit linearly polarized electromagnetic waves, polarization mismatch will also occur on the satellite antenna, which will also cause half of the energy loss. Summary of the invention

[0003] The present application provides an electronic device that can realize the reception and transmission of circularly polarized electromagnetic waves, thereby improving the signal strength and transmission efficiency of the electronic device in satellite communications.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] In the first aspect, the present application provides an electronic device, comprising: a first antenna unit, a second antenna unit, a conductive frame, and a shell connected to the conductive frame; wherein the conductive frame is arranged around the periphery of the shell; the first antenna unit comprises: a first radiator, the first radiator is a part of the conductive frame; the second antenna unit comprises: a second radiator, the second radiator is rotatably connected to the shell, and the second radiator comprises: a first state; when the second radiator is in the first state, the angle between the second radiator and the shell is a preset angle, and part of the second radiator is located outside the shell; the first antenna unit and the second antenna unit are used to send or receive circularly polarized waves when the angle between the second radiator and the shell is a preset angle. wherein the electromagnetic waves used in satellite communication are circularly polarized electromagnetic waves.

[0006] Thus, through the cooperation of the first antenna unit and the second antenna unit, the electronic device can receive and send circularly polarized electromagnetic waves, which reduces the energy loss of the electronic device caused by polarization mismatch during satellite communication, and improves the signal strength and transmission efficiency of the electronic device during satellite communication. At the same time, since the second radiator is rotatably connected to the shell, when there is no need to transmit and receive circularly polarized electromagnetic waves, the second radiator can be rotated to the side close to the shell, saving space for the electronic device and facilitating the storage and carrying of the electronic device. In addition, in the first state, there are fewer electronic devices and less clutter around the second radiator, which has better transmission efficiency than the radiator arranged inside the electronic device. Moreover, when the second radiator is in the first state, the second radiator can be used as a shell bracket of the electronic device to add new functions and new appearance effects to the electronic device.

[0007] In a possible implementation of the first aspect, the electronic device further includes: a modulator, the modulator being electrically connected to the first antenna unit and the second antenna unit, and the modulator being configured to adjust signals input to the first antenna unit and the second antenna unit in response to a preset angle, so that the first antenna unit and the second antenna unit send or receive circularly polarized waves according to the input signals. The modulator may adjust parameters such as an electric field phase and an electric field power of the signals input to the first antenna unit and the second antenna unit.

[0008] Thus, when the second radiator is in the first state, the modulator can adjust the electric field phase, electric field power and other parameters of the signal input to the first antenna unit and the second antenna unit accordingly, so that the first antenna unit and the second antenna unit send or receive circularly polarized waves according to the input signal, reducing the energy loss caused by polarization mismatch and improving the signal strength and transmission efficiency of the electronic device during satellite communication. Compared with the original antenna design for satellite communication in electronic equipment, when the first antenna unit and the second antenna unit can cooperate to realize the reception and transmission of circularly polarized electromagnetic waves, the path loss of satellite communication can be reduced by 3dB in theory, thereby improving the channel capacity and communication reliability of satellite communication.

[0009] 3dB is a relative value used to indicate the proportional relationship between two power values. Specifically, if the power of a signal drops to half of its original value, then this change is -3dB on a logarithmic scale. In wireless communications, a 3dB difference is a very important indicator, which usually represents a halving of signal strength or a halving of power, and has a decisive influence on the success rate of communications.

[0010] In a possible implementation of the first aspect, the second radiator further includes a second state, and when the second radiator is in the second state, the angle between the second radiator and the housing is less than a preset angle. Thus, when the first antenna unit and the second antenna unit are not needed to receive and transmit circularly polarized waves, the second radiator can be rotated to the second state, saving space in the electronic device and facilitating storage and carrying of the electronic device.

[0011] In a possible implementation manner of the first aspect, when the second radiator is in the second state, an angle between the second radiator and the housing is 0°, thereby further storing the second radiator.

[0012] In a possible implementation of the first aspect, a first groove is provided on the housing, and the second radiator is disposed in the first groove. Thus, when the second radiator is in the second state, the thickness of at least part of the second radiator coincides with the thickness of the housing, thereby reducing the thickness of the electronic device and improving the structural compactness of the electronic device.

[0013] In a possible implementation of the first aspect, the length of the first groove is greater than the length of the second radiator. Thus, the second radiator can be embedded in the first groove, making the electronic device compact.

[0014] In a possible implementation of the first aspect, the electronic device further includes: a rotating shaft, and one end of the second radiator is rotatably connected to the housing via the rotating shaft. Thus, the second radiator and the housing are connected using the rotating shaft, which has a simple structure and is easy to manufacture.

[0015] In a possible implementation of the first aspect, the rotating shaft is disposed on an inner wall on one side in the length direction of the first groove, thereby reducing the thickness of the electronic device and making the electronic device compact.

[0016] In a possible implementation of the first aspect, when the electronic device further includes a rotating shaft, the shell further includes: a fixed structure, the rotating shaft is rotatably connected to the fixed structure, the rotating shaft is provided with a convex portion, the fixed structure includes a second groove, and the convex portion and the second groove are used to engage when there is a preset angle between the second antenna unit and the shell. The cooperation of the convex portion and the second groove enables the angle between the second radiator and the shell to be stabilized at a preset angle when the second radiator is in the first state, so that the polarization direction of the second antenna unit remains stable in the first state, thereby improving the communication stability of the second antenna unit when cooperating with the first antenna unit to receive and send circularly polarized electromagnetic waves. At the same time, when the second radiator is stable in the first state, the second radiator can be used as a shell bracket of the electronic device, and the shell bracket can remain stable in the first state, adding new functions and new appearance effects to the electronic device.

[0017] In a possible implementation of the first aspect, when the electronic device further includes a rotating shaft, the electronic device further includes a feeding device; the rotating shaft is made of a conductive material, and the second radiator is electrically connected to the feeding device via the rotating shaft. Thus, the second radiator can be fed by the rotating shaft, and no other structure is required for feeding, and the structure is simple.

[0018] In a possible implementation of the first aspect, when the electronic device further includes a modulator and the second radiator is electrically connected to the feeding device via the shaft, the second radiator is also electrically connected to the modulator via the shaft, thereby improving the space utilization of the electronic device by using the multiplexed shaft as a connection point.

[0019] In a possible implementation of the first aspect, the electronic device further includes: a first connecting device, and a circuit board and a middle frame stacked with the shell, the circuit board is arranged on a side of the middle frame close to the shell, the feeding device is electrically connected to the circuit board, and the feeding device is electrically connected to the shaft through the first connecting device. Thus, the second radiator can be fed through the shaft and the first connecting device, and no additional feeding point is required, and the structure is compact.

[0020] In a possible implementation of the first aspect, the first connecting device includes: at least one of a metal spring sheet and a metal wire, thereby achieving a simple structure.

[0021] In a possible implementation of the first aspect, a first connection portion is provided on the housing, and a second connection portion is provided on the second radiator; when the second radiator is in the second state, the first connection portion is connected to the second connection portion. In this way, when the second radiator is in the second state, it is both rotationally connected to the housing and connected through the first connection portion and the second connection portion, and the two connection points are combined together, so that the second radiator is stably connected to the housing in the second state, avoiding damage caused by frequent rotation of the second radiator when the user moves the electronic device, and increasing the service life of the second radiator.

[0022] In a possible implementation of the first aspect, the first connection part is made of a magnet, and the second connection part is made of a metal material, so that the second radiator is adsorbed on the housing by magnetic attraction in the second state, and the connection is stable.

[0023] In a possible implementation of the first aspect, the first connection portion includes a card slot, and the shape of the second connection portion is adapted to the shape of the card slot. Thus, in the second state, at least part of the second connection portion is located in the card slot, which can reduce the thickness of the electronic device and improve the structural compactness of the electronic device.

[0024] In a possible implementation manner of the first aspect, both the first connection portion and the second connection portion include conductive materials, so that the second radiator can be electrically connected to other components in the electronic device through the first connection portion in the second state.

[0025] In a possible implementation of the first aspect, the electronic device further includes a ground plate, and the ground plate is electrically connected to the first connection portion. In this way, the second antenna unit can be grounded through the first connection portion when the second radiator is in the second state, and no separate grounding point needs to be provided, so that the overall structure of the electronic device is more compact.

[0026] In a possible implementation of the first aspect, the second antenna unit further includes a reflector, which is disposed on a side of the second radiator away from the first radiator. In this way, the reflector can reflect electromagnetic waves on the side away from the first radiator toward the side close to the first radiator, so that the electromagnetic waves are superimposed on the electromagnetic waves emitted by the first radiator, thereby enhancing the directivity of the antenna unit formed by the first antenna unit and the second antenna unit, and improving the gain of the antenna unit.

[0027] In a possible implementation of the first aspect, the second antenna unit further includes a reflector, which is disposed on a side of the second radiator away from the maximum radiation direction of the second radiator. In this way, the reflector can reflect electromagnetic waves opposite to the maximum radiation direction of the second radiator toward the maximum radiation direction of the second radiator, so that the electromagnetic waves are superimposed with the electromagnetic waves in the maximum radiation direction of the second radiator, thereby enhancing the directivity of the antenna and improving the gain of the second antenna unit.

[0029] In this way, the second antenna unit can not only receive and send the first radio frequency signal together with the first antenna unit when the second radiator is in the first state. The second antenna unit can also receive and send the second radio frequency signal when the second radiator is in the second state. Thus, the function of the second antenna unit is increased, and the reuse of the second antenna unit is realized. At the same time, using the second antenna unit to receive and send the second radio frequency signal when the second radiator is in the second state is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal inside the electronic device outside the electronic device, so that other antenna units inside the electronic device have a larger size design space, thereby improving the performance of other antenna units inside the electronic device.

[0030] In a possible implementation of the first aspect, the electronic device further includes: a first combiner, a first tuning switch circuit, a processor, a first radio module, a second radio frequency module, and a third radio frequency module, the second antenna unit is electrically connected to the first combiner, the first combiner is electrically connected to the first radio frequency module, the second radio frequency module, and the third radio frequency module, the first radio frequency module, the second radio frequency module, and the first tuning switch circuit are all electrically connected to the processor; the processor is used to control the first radio frequency module to transmit the first radio frequency signal to the second antenna unit when the second radiator is in the first state; the processor is also used to control the second radio frequency module to transmit the first radio frequency signal to the second antenna when the second radiator is in the second state. The unit transmits a second radio frequency signal; the processor is also used to control the third radio frequency module to transmit a third radio frequency signal to the second antenna unit when the second radiator is in the second state; wherein, when the second radiator is in the second state, the first tuning switch circuit is electrically connected to the second antenna unit, and the processor is used to adjust the resonant frequency of the second antenna unit through the first tuning switch circuit according to the second radio frequency signal, so that the resonant frequency of the second antenna unit is within the frequency band of the second radio frequency signal; the processor is also used to control the first tuning switch circuit to adjust the resonant frequency of the second antenna unit according to the third radio frequency signal, so that the resonant frequency of the second antenna unit is within the frequency band of the third radio frequency signal.

The second antenna unit can also receive and send the second radio frequency signal and the third radio frequency signal when the second radiator is in the second state. Thus, the function of the second antenna unit is increased, and the reuse of the second antenna unit is realized. At the same time, using the second antenna unit to receive and send the second radio frequency signal and the third radio frequency signal when the second radiator is in the second state is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal and the third radio frequency signal inside the electronic device outside the electronic device, so that other antenna units inside the electronic device have a larger size design space, thereby improving the performance of other antenna units inside the electronic device.

[0032] In a possible implementation of the first aspect, the electronic device also includes a second combiner, a second tuning switch circuit, a processor, a first RF module, and a second RF module; the first antenna unit is electrically connected to the second combiner, and the second combiner is electrically connected to the first RF module and the second RF module; the second tuning switch circuits of the first RF module and the second RF module are both electrically connected to the processor; the processor is used to control the first RF module to transmit a first RF signal to the first antenna unit when the second radiator is in a first state, and the processor is also used to control the second RF module to transmit a second RF signal to the first antenna unit when the second radiator is in a second state; wherein the second tuning switch circuit is electrically connected to the first antenna unit; when the second radiator is in the first state, the processor is used to adjust the resonant frequency of the first antenna unit through the second adjustment switch circuit according to the first RF signal, so that the resonant frequency of the first antenna unit is within the frequency band of the first RF signal; the processor is also used to adjust the resonant frequency of the first antenna unit through the second tuning switch circuit according to the second RF signal, so that the resonant frequency of the first antenna unit is within the frequency band of the second RF signal.

[0033] Therefore, the first antenna unit can not only receive and send the first radio frequency signal together with the second antenna unit when the second radiator is in the first state. The first antenna unit can also receive and send the second radio frequency signal when the second radiator is in the second state. Thus, the function of the first antenna unit is increased, and the reuse of the second antenna unit is realized. At the same time, using the first antenna unit to receive and send the second radio frequency signal is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal inside the electronic device on the first antenna unit, reducing the number of antennas inside the electronic device, so that other antenna units inside the electronic device have a larger size design space, thereby improving the performance of other antenna units inside the electronic device.

[0035] Therefore, the first antenna unit can not only receive and send the first radio frequency signal together with the second antenna unit when the second radiator is in the first state. The first antenna unit can also receive and send the second radio frequency signal and the third radio frequency signal when the second radiator is in the second state. Thus, the function of the first antenna unit is increased, and the reuse of the second antenna unit is realized. At the same time, using the first antenna unit to receive and send the second radio frequency signal and the third radio frequency signal is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal and the third radio frequency signal inside the electronic device on the first antenna unit, reducing the number of antennas inside the electronic device, so that other antenna units inside the electronic device have a larger size design space, thereby improving the performance of other antenna units inside the electronic device.

[0080] The shell 30 can be a back cover made of metal material; it can also be a back cover made of non-conductive material, such as glass back cover, plastic back cover, ceramic back cover and other non-metallic back covers; it can also be a back cover made of both conductive material and non-conductive material.

[0081] In some embodiments, the housing 30 including a conductive material can replace the middle frame 20 and be integrated with the frame 40 to support the electronic components in the entire device.

[0082] The electronic device 100 may further include a frame 40. In some embodiments, the frame 40 may be formed of a conductive material such as metal. The frame 40 may be disposed between the display module 10 and the housing 30 and extend circumferentially around the periphery of the electronic device 100. The frame 40 may have four sides surrounding the display module 10 to help fix the display module 10. In one implementation, the frame 40 made of a metal material may be directly used as a metal frame of the electronic device 100, forming the appearance of a metal frame, which is suitable for a metal industrial design (ID). In other embodiments, the outer surface of the frame 40 may also be a non-metallic material, such as a plastic frame, to form the appearance of a non-metallic frame, which is suitable for a non-metallic ID.

[0083] In some embodiments, the frame 40 is a separate structure. In other embodiments, the frame 40 can be regarded as a part of the middle frame 20, and the middle frame 20 including the frame 40 is an integral part, which can support the electronic devices in the whole machine.

[0084] The electronic device 100 includes at least one antenna unit and at least one radio frequency module 60. The antenna unit includes an antenna radiator ( Figure 2(not shown). The RF module 60 is electrically connected to the antenna unit to transmit and receive electromagnetic signals to the antenna unit through the feeding point. The antenna unit radiates electromagnetic waves according to the received electromagnetic signals or sends electromagnetic signals to the RF module 60 according to the received electromagnetic waves, thereby realizing the transmission and reception of wireless signals. Among them, the RF module (Radio Frequency module, AF module) 60 is a circuit such as a transceiver (transmitter and / or receiver, T / R) that can transmit and / or receive RF signals.

[0085] In some embodiments, the frame 40 includes a conductive material, and the frame 40 can at least partially serve as an antenna radiator to receive / transmit radio frequency signals. There can be a gap between this portion of the frame 40 that serves as the antenna radiator and other portions of the middle frame 20, or between the frame 40 and the middle frame 20, thereby ensuring that the antenna radiator has a good radiation environment.

[0086] In other embodiments, the antenna radiator of the electronic device 100 may also be disposed in the frame 40. The frame 40 includes a non-conductive material, and the antenna radiator may be located in the electronic device 100 and disposed along the frame 40, or the antenna radiator may be at least partially embedded in the non-conductive material of the frame 40.

[0087] In some other embodiments, the antenna radiator of the electronic device 100 may also be disposed in the housing 30, such as a bracket antenna, a millimeter wave antenna, etc. ( Figure 2 There may be a gap between the antenna radiator disposed in the housing 30 and other conductive parts inside the housing 30, thereby ensuring that the antenna radiator has a good radiation environment.

[0088] Currently, the electronic device 100 can be applied to communication transmission in various frequency bands, such as cellular, Bluetooth, WIFI, satellite communication, etc. Among them, satellite communication has a wide coverage, large communication capacity, and good transmission quality. In recent years, it has been gradually widely used in global positioning system (GPS) GPS positioning, voice and video calls, etc.

[0089] Different communication methods often use electromagnetic waves with different polarization modes to transmit signals based on their own characteristics, application scenarios, transmission requirements and other factors. For example, cellular, Bluetooth, WIFI and other communication methods often use linearly polarized electromagnetic waves to transmit signals. Figure 3 , Figure 3The figure is a schematic diagram of the polarization direction of linearly polarized electromagnetic waves. Linear polarization is a polarization mode in which the electric field vector has a fixed orientation in space and the endpoint moves in a straight line over time at a fixed point in space. Electromagnetic waves under this polarization mode can better adapt to the relatively fixed signal transmission direction requirements when transmitted between communication base stations and mobile terminals, and it is also easier to achieve antenna miniaturization and low power consumption requirements in device design.

[0090] Satellite communications use circularly polarized electromagnetic waves. Figure 4 , Figure 4 Schematic diagram of the polarization direction of circularly polarized electromagnetic waves. Circular polarization refers to a polarization mode in which the trajectory of the endpoint of the electric field vector moving over time at a fixed point in space is circular. Satellite communications need to cover a wide geographical area, including various terrains such as oceans and land, and the satellite is in a state of constant motion relative to the ground receiving station. Circularly polarized electromagnetic waves maintain good signal transmission performance when the relative position and angle between the satellite and the ground station are constantly changing. Compared with linearly polarized waves, circularly polarized waves will not cause serious signal attenuation due to slight deviations in the polarization direction during reception, thereby improving the reliability and coverage of satellite communications.

[0091] Compared with linear polarization antennas, circular polarization antennas are often more complex in structure. However, electronic devices 100, such as mobile phones, have compact and complex internal structures. There are many electronic components around the antenna unit, such as chips and batteries, which limit the space and design of the antenna, making it difficult to construct a complex structure for the antenna unit inside the electronic device 100. Under such structural limitations, the antenna unit in the electronic device 100 can only achieve linear polarization.

[0092] When the electronic device 100 uses a linearly polarized antenna unit to receive circularly polarized electromagnetic waves transmitted by a satellite, half of the energy will be lost due to polarization mismatch. Conversely, the linearly polarized electromagnetic waves emitted by the linearly polarized antenna unit of the electronic device 100 will also produce polarization mismatch at the satellite antenna end, which will also cause half of the energy loss. Half of the energy loss means a 3dB performance degradation in the communication index, and the 3dB difference can have a decisive impact on the communication success rate.

[0093] Polarization mismatch refers to the inconsistency between the polarization directions of the transmitting antenna and the receiving antenna in a wireless communication system, resulting in power loss during signal transmission. 3dB is a relative value used to indicate the proportional relationship between two power values. Specifically, if the power of a signal drops to half of its original value, then this change is -3dB on a logarithmic scale. In wireless communications, a 3dB difference is a very important indicator, which usually represents a halving of the signal strength or a halving of the power, and has a decisive influence on the success rate of communication.

[0094] Therefore, the present application provides an electronic device, which provides a radiator rotatably connected to the shell 30 so that the antenna unit corresponding to the radiator cooperates with the antenna unit inside the electronic device 100 to realize the reception and transmission of circularly polarized electromagnetic waves, thereby improving the signal strength and transmission efficiency of the electronic device 100 in satellite communications.

[0095] See also Figure 5 , Figure 5 The three-dimensional structure diagram of the electronic device 100 provided in some embodiments of the present application, the electronic device 100 includes a first antenna unit 51, a second antenna unit 52, a conductive frame 22, a first radio frequency module 61 ( Figure 5 The conductive frame 22 is disposed around the outer periphery of the housing 30.

[0096] The first antenna unit 51 includes a first radiator 511, and the first radiator 511 is a part of the conductive frame 22. In some embodiments, the conductive frame 22 is disposed on the middle frame 20. In other embodiments, the conductive frame 22 is a part of the frame 40. In other embodiments, when the frame 40 includes an insulating material, the conductive frame 22 may also be embedded in the frame 40. This application is not limited to this.

[0097] When the conductive frame 22 is formed by at least a portion of the frame 40 of the electronic device 100, the conductive frame 22 may be, for example, a conductive frame arranged around the periphery of the electronic device 100. In some embodiments, the conductive frame 22 may be, for example, a straight strip frame on the frame 40, such as Figure 5 As shown, or a section of an L-shaped frame where the top of the frame 40 and the side of the frame 40 are connected.

[0098] It should be noted that the conductive frame 22 can be a conductive frame formed by conductive materials such as metal, or a conductive frame 22 formed by non-conductive materials such as plastic and resin, and a conductive radiator arranged on the inside of the non-conductive material, or a conductive radiator embedded in the non-conductive material.

[0099] The first radiator 511 is used for satellite communication. The present application does not limit the location of the first radiator 511. The transmission direction of the electromagnetic wave of satellite communication is vertical or approximately vertical to the ground. Therefore, in order to align the maximum radiation direction of the first radiator 511 with the incoming wave direction to improve the gain of the first antenna unit 51. In some embodiments, the first radiator 511 is arranged parallel to the top of the middle frame 20. Figure 5 In some other embodiments, the first radiator 511 may also be directly disposed on the top of the middle frame 20 .

[0100] The maximum radiation direction refers to the direction in which the electromagnetic wave intensity is the highest when the antenna radiates in space, and the antenna gain is used to characterize the degree to which the antenna input power is concentratedly radiated. Generally, the narrower the main lobe of the antenna pattern and the smaller the side lobe, the higher the antenna gain.

[0101] It should be noted that in the embodiments of the present application, it is assumed that when a user holds the electronic device (usually vertically and facing the screen), the electronic device 100 and the components included in the electronic device 100 have a top, a bottom, a left side and a right side.

[0102] The second antenna unit 52 includes a second radiator 521, a portion of which is located outside the housing 30, and the second radiator 521 is rotatably connected to the housing 30. The present application does not limit the structure of the housing 30. Exemplarily, the housing 30 may be a back cover or the frame 40 and the back cover may be integrally formed.

[0103] The second radiator 521 includes a first state; when the second radiator 521 is in the first state, please refer to Figure 6 , Figure 6 This is a top view schematic diagram of an electronic device 100 provided in some embodiments of the present application. At this time, the second radiator 521 is in the first state, and the angle between the second radiator 521 and the housing 30 is a preset angle r.

[0104] The first antenna unit 51 and the second antenna unit 52 are used to generate circularly polarized waves when the angle between the second radiator 521 and the housing 30 is a preset angle r.

[0105] The present application does not limit the polarization modes of the first antenna unit 51 and the second antenna unit 52, as long as the first antenna unit 51 and the second antenna unit 52 can generate circularly polarized waves when the angle between the second radiator 521 and the housing 30 is a preset angle r. Exemplarily, the polarization modes of the first antenna unit 51 and the second antenna unit 52 are both linear polarization.

[0106] The electronic device 100 further includes a feeding device 1 ( Figure 5 not shown) and the ground plate 2 ( Figure 5 (not shown). The present application does not limit the feeding method and grounding method of the first antenna unit 51 and the second antenna unit 52. In some embodiments, the first antenna unit 51 and the second antenna unit 52 can be electrically connected to the feeding device 1 and the grounding plate 2 respectively by providing a conductive structure, such as a metal spring, a metal wire, etc. In other embodiments, the first antenna unit 51 and the second antenna unit 52 can be electrically connected to the feeding device 1 and the grounding plate 2 by providing a coupling structure.

[0107] It should be noted that in the above and the following embodiments, the electrical connection can be to electrically connect two components through a physical conductive structure, or to electrically connect two components by setting a coupling structure, which will not be described in detail below. Coupling refers to the phenomenon that there is a close fit and mutual influence between the input and output of two or more circuit elements or electrical networks, and energy is transmitted from one side to the other through interaction.

[0108] The first RF module 61 is used to transmit a first RF signal to the first antenna unit 51 and the second antenna unit 52. The present application does not limit the frequency band of the first RF signal, as long as the electromagnetic wave used when the first RF signal is transmitted in space is a circularly polarized electromagnetic wave. Exemplarily, the frequency band of the first RF signal is the frequency band of the electromagnetic wave used by the electronic device 100 when performing satellite communication, that is, the working frequency band of the first antenna unit 51.

[0109] In some embodiments, the operating frequency bands of the first antenna unit 51 include L1 (1575.42±1.023MHz) band, L5 (1176.45±1.023MHz) band, S wave (2-4GHz) band and other signal bands that use circularly polarized electromagnetic waves for satellite communications.

[0110] The first antenna unit 51 and the second antenna unit 52 include at least one frequency point which is the same as the frequency of the electromagnetic wave used by the first radio frequency signal, so that the first antenna unit 51 and the second antenna unit 52 can both send and receive the first radio frequency signal.

[0111] The first antenna unit 51 and the second antenna unit 52 are electrically connected to the first RF module 61. When transmitting the first RF signal, the first RF module 61 sends the first RF signal to the first antenna unit 51 and the second antenna unit 52 through the feeding points of the first antenna unit 51 and the second antenna unit 52 respectively. The first antenna unit 51 and the second antenna unit 52 respectively transmit electromagnetic waves propagating in a linearly polarized manner in space according to the received first RF signal, and the two linearly polarized electromagnetic waves are synthesized into a circularly polarized wave in space, thereby realizing the transmission of circularly polarized electromagnetic waves. Similarly, when receiving satellite signals, the circularly polarized electromagnetic waves are decomposed into two linearly polarized electromagnetic waves along the polarization direction of the first antenna unit 51 and the polarization direction of the second antenna unit 52. The first antenna unit 51 and the second antenna unit 52 respectively receive the linearly polarized electromagnetic waves with the same polarization direction as their respective polarization directions and convert them into two RF signals. The two RF signals are synthesized into one first RF signal and sent to the first RF module, thereby realizing the reception of circularly polarized electromagnetic waves.

[0112] Thus, through the cooperation of the first antenna unit 51 and the second antenna unit 52, the electronic device 100 can receive and send circularly polarized electromagnetic waves, reduce the energy loss of the electronic device 100 due to polarization mismatch during satellite communication, and improve the signal strength and transmission efficiency of the electronic device 100 during satellite communication. At the same time, since the second radiator 521 is rotatably connected to the housing 30, when it is not necessary to transmit and receive circularly polarized electromagnetic waves, the second radiator 521 can be rotated to the side close to the housing 30, saving space of the electronic device 100 and facilitating the storage and carrying of the electronic device 100. In addition, in the first state, there are fewer electronic devices and less clutter around the second radiator 521, and compared with the radiator arranged inside the electronic device 100, it has better transmission efficiency. Moreover, when the second radiator 521 is in the first state, the second radiator 521 can be used as a housing bracket of the electronic device 100, adding new functions and new appearance effects to the electronic device 100.

[0113] In some embodiments, the second radiator 521 further includes: a second state, when the second radiator 521 is in the second state, the angle between the second radiator 521 and the housing 30 is less than the preset angle r. Therefore, when the first antenna unit 51 and the second antenna unit 52 are not needed to receive and transmit circularly polarized waves, the second radiator 521 can be rotated to the second state, saving space of the electronic device 100 and facilitating the storage and carrying of the electronic device 100.

[0114] There is no limitation on the angle between the second radiator 521 and the housing in the second state. For example, when the second radiator 521 is in the second state, the angle between the second radiator 521 and the housing 30 is 0°. Thus, the second radiator 521 can be further stored.

[0115] In some embodiments, the electronic device 100 also includes a modulator 70, which is electrically connected to the first antenna unit 51 and the second antenna unit 52. The modulator 70 is used to adjust the signals input to the first antenna unit 51 and the second antenna unit 52 in response to a preset angle r, so that the first antenna unit 51 and the second antenna unit 52 send or receive circularly polarized waves according to the input signals.

[0116] When the second radiator 521 is in the first state, the signal input to the first antenna unit 51 and the second antenna unit 52 is the first radio frequency signal. Figure 8 As shown, Figure 8 A schematic diagram of the circuit structure corresponding to the electronic device 100 provided in some embodiments of the present application.

[0117] The modulator 70 may adjust parameters such as the electric field phase and the electric field power of the signal input to the first antenna unit 51 and the second antenna unit 52 .

[0118] The present application does not limit the specific structure of the phase modulator 70. Exemplarily, the modulator 70 may be a combination of a capacitor and an inductor to adjust the phase and power of the electric field of the first RF signal sent by the first communication RF module to the first antenna unit 51 and the second antenna unit 52. In some embodiments, the modulator 70 may include a power adjustment device, a power distribution device, a phase adjustment device, and other structures that can adjust the RF signal parameters.

[0119] The present application does not limit the specific position of the modulator 70 on the electronic device 100. For example, the modulator 70 may be disposed on the circuit board 23.

[0120] The size of the preset angle r can be adjusted according to the polarization direction of the first antenna unit 51 and the polarization direction of the second antenna unit 52, so that in the first state, the polarization directions of the first antenna unit 51 and the second antenna unit 52 are perpendicular.

[0121] In some embodiments, Figure 5 As shown, when the polarization direction of the first antenna unit 51 is parallel to the X-axis, and the polarization direction of the second antenna unit 52 is also parallel to the X-axis when the angle between the second radiator 521 and the housing 30 is 0°, the preset angle r is 90°. In this way, when the second radiator 521 is in the first state, the polarization direction of the second antenna unit 52 is parallel to the Y-axis or the Z-axis. As a result, the polarization direction of the first antenna unit 51 is perpendicular to the polarization direction of the second antenna unit 52.

[0122] At the same time, the modulator 70 responds to the preset angle r so that the phase difference between the electric field of the first antenna unit 51 and the electric field of the second antenna unit 52 with perpendicular polarization directions is 90° (or 270°), and the electric field components of the synthesized electric field of the first antenna unit 51 and the second antenna unit are equal in amplitude in two orthogonal directions.

[0123] Thus, when the second radiator 521 is in the first state, the modulator 70 can adjust the electric field phase, electric field power and other parameters of the signal input to the first antenna unit 51 and the second antenna unit 52 accordingly, so that the first antenna unit 51 and the second antenna unit 52 send or receive circularly polarized waves according to the input signal, reducing the energy loss caused by polarization mismatch and improving the signal strength and transmission efficiency of the electronic device 100 during satellite communication. Compared with the original antenna design for satellite communication in the electronic device 100, when the first antenna unit 51 and the second antenna unit 52 can cooperate to realize the reception and transmission of circularly polarized electromagnetic waves, the path loss of satellite communication can be reduced by 3dB in theory, thereby improving the channel capacity and communication reliability of satellite communication.

[0124] Among them, when the electric field power of the signal input to the first antenna unit 51 and the second antenna unit 52 is adjusted, the electric field power of the signal input to the two antenna units can be distributed and adjusted according to the radiation capabilities of the first antenna unit 51 and the second antenna unit 52, so that the output power of the two antenna units is equal, and then the electric field amplitude of the synthetic electric field output by the two antenna units is equal in two orthogonal directions. Therefore, when the second radiator 521 is in the first state and the phase difference between the electric field of the first antenna unit 51 and the second antenna unit 52 is 90° (or 270°), the first antenna unit 51 and the second antenna unit 52 can cooperate to realize the reception and transmission of circularly polarized electromagnetic waves.

[0125] In order to protect the second radiator 521, in some embodiments, as Figure 5 As shown, the second antenna unit 52 further includes a support structure 522. The support structure 522 wraps part of the second radiator 521 inside the support structure 522 to prevent the performance of the second antenna unit 52 from being affected by the external environment.

[0126] The present application does not limit the shape of the support structure 522. For example, the support structure 522 may be in a strip, column, block, etc., and the cross-sectional shape of the support structure 522 may be circular, rectangular, or irregular. Figure 5 The description is made by taking the supporting structure 522 as a rectangular column as an example.

[0127] The present application does not limit the rotation direction of the second radiator 521, as long as the first antenna unit 51 and the second antenna unit 52 can receive and send circularly polarized electromagnetic waves in the first state. In some embodiments, the second radiator 521 rotates around the housing 30 with the direction parallel to the Y axis as the axis, such as Figure 5 In some other embodiments, see Figure 7 , Figure 7The three-dimensional structural diagram of the electronic device 100 provided in some other embodiments of the present application, the second radiator 521 can also rotate around the housing 30 with the direction parallel to the X-axis as the axis.

[0128] It can be understood that the rotation direction of the second radiator 521 relative to the housing 30 does not affect the maximum radiation transmission direction of the second radiator 521 in the first state. In some embodiments, since the electromagnetic wave transmission direction of satellite communication is vertical or approximately vertical to the ground, when the user uses the electronic device 100 to use the second antenna unit 52 and the first antenna unit 51 for satellite communication, the maximum radiation direction of the second radiator 521 points from the bottom of the electronic device 100 to the top of the electronic device 100, such as Figure 5 and Figure 7 As shown by the middle arrow X1, the maximum radiation direction of the first radiator 511 is aligned with the incoming wave direction, thereby improving the transmission efficiency of the signal.

[0129] See also Fig. 9 , Fig. 9 Schematic diagram of the three-dimensional structure of the electronic device 100 provided in some embodiments of the present application. A first groove a1 is provided on the housing 30, and the second radiator 521 is arranged in the first groove a1. Therefore, when the second radiator 521 is in the second state, the thickness of at least part of the second radiator 521 coincides with the thickness of the housing 30, which reduces the thickness of the electronic device 100 and improves the structural compactness of the electronic device 100.

[0130] The present application does not limit the size of the first groove a1. For example, the length of the first groove a1 is greater than the length of the second radiator 521. Therefore, the second radiator 521 can be embedded in the first groove a1, so that the electronic device 100 has a compact structure.

[0131] The present application does not limit the shape of the first groove a1. For example, the shape of the first groove a1 matches the shape of the second radiator 521. When the second radiator 521 is a rectangular column, Fig. 9 As shown, the first groove a1 is also in the shape of a rectangular column.

[0132] In some embodiments, see Fig.10 , Fig.10 The cross-sectional structure diagram of the electronic device 100 provided in some embodiments of the present application, the electronic device 100 further includes: a rotating shaft 80, and one end of the second radiator 521 is rotatably connected to the housing 30 through the rotating shaft 80. Therefore, the second radiator 521 and the housing 30 are connected by the rotating shaft 80, which has a simple structure and is easy to manufacture.

[0133] The present application does not limit the location of the rotating shaft 80 on the electronic device 100, as long as the second radiator 521 can rotate around the housing 30 relative to the rotating shaft 80. For example, when the housing 30 is provided with a first groove a1, as shown in FIG. Fig.10 As shown, the rotating shaft 80 is disposed on one inner wall of the first groove a1 in the length direction, thereby reducing the thickness of the electronic device 100 and making the electronic device 100 compact.

[0134] The present application does not limit the material of the rotating shaft 80. In some embodiments, please continue to refer to Fig.10 The electronic device 100 further includes a feeding device 1, the shaft 80 is made of a conductive material, and the second radiator 521 is electrically connected to the feeding device 1 through the shaft 80. For example, the shaft 80 can be made of a metal conductive material. Thus, the second radiator 521 can be fed by the shaft 80, and no other structure is required for feeding, and the structure is simple.

[0135] It is understandable that when the second radiator 521 is electrically connected to the feeding device 1 through the shaft 80 , the second radiator 521 can also be electrically connected to the phase modulator 70 through the shaft 80 to reuse the shaft 80 as a connection point, thereby improving space utilization of the electronic device 100 .

[0136] In some embodiments, the second radiator 521 can also use the rotating shaft 80 and the ground plate 2 ( Fig.10 The second antenna unit 52 is electrically connected to the antenna radiator (not shown) to achieve grounding of the second antenna unit 52. At this time, the feeding point and the grounding point of the second antenna unit 52 are both located at one end of the antenna radiator, and the structure is simple.

[0137] It is understandable that, in other embodiments, the second antenna unit 52 may also be provided with other feeding points or grounding points so that the second radiator 521 is electrically connected to the feeding device 1 and the grounding plate 2. Exemplarily, a feeding point or grounding point may be provided at any one of the two opposite ends of the second radiator 521, or at any position between the two opposite ends of the second radiator 521, as long as at least one of the operating frequency bands of the second antenna unit 52 is the same as the operating frequency band of the first antenna unit 51.

[0138] Likewise, the second antenna unit 52 may also be provided with other conductive devices or conductive points to be electrically connected to the modulator 70 .

[0139] In some embodiments, see Fig.11 , Fig.11The cross-sectional structure diagram of the electronic device 100 provided in some other embodiments of the present application, the electronic device 100 further includes: a first connecting device b1, and a circuit board 23 and a middle frame 20 stacked with the housing 30, the circuit board 23 is arranged on a side of the middle frame 20 close to the housing 30, the feeding device 1 is electrically connected to the circuit board 23, and the feeding device 1 is electrically connected to the shaft 80 through the first connecting device b1. Thus, the second radiator 521 can be fed through the shaft 80 and the first connecting device b1, without setting up a separate feeding point, and the structure is compact.

[0140] The first connection device b1 is a conductive structure, and the present application does not limit the material and structure of the first connection device b1. In some embodiments, the first connection device b1 includes at least one of a metal spring sheet and a metal wire, thereby making the structure simple.

[0141] Exemplarily, the first connection device b1 includes a metal trace of a flexible printed circuit (FPC), whereby the FPC metal trace can be used to perform high-precision signal transmission and current transmission, thereby improving communication quality.

[0142] See also Fig.12 , Fig.12 A partial structural diagram of an electronic device 100 provided in some embodiments of the present application. In some embodiments, when the electronic device 100 includes a rotating shaft 80, the housing 30 further includes: a fixing structure 31, the rotating shaft 80 is rotatably connected to the fixing structure 31, the rotating shaft 80 is provided with a convex portion 80a, the fixing structure 31 includes a second groove a2, and the convex portion 80a and the second groove a2 are used for clamping when there is a preset angle r between the second radiator 521 and the housing 30.

[0143] The present application does not limit the number and arrangement of the protrusion 80a and the second groove a2, as long as the protrusion 80a is engaged in the second groove a2 when the second radiator 521 is in the first state. In some embodiments, there are two protrusions 80a, which are respectively arranged at both ends of the rotating shaft 80. Fig.12 In some other embodiments, see Fig.13 , Fig.13 This is a partial exploded structural diagram of an electronic device 100 provided in some embodiments of the present application, wherein there are four protrusions 80a and four second grooves a2, and the two protrusions 80a are respectively located at both ends of the rotating shaft 80, and the two protrusions 80a located at the same end of the rotating shaft 80 are arranged at intervals along the circumference of the rotating shaft 80. When the second radiator 521 rotates around the rotating shaft 80 to form a preset angle r with the housing 30, one protrusion 80a is arranged in one second groove a2, so that the second radiator 521 can be stabilized in the first state.

[0144] The cooperation of the protrusion 80a and the second groove a2 enables the angle between the second radiator 521 and the housing 30 to be stabilized at a preset angle r when the second radiator 521 is in the first state, so that the polarization direction of the second antenna unit 52 remains stable in the first state, thereby improving the communication stability of the second antenna unit 52 when cooperating with the first antenna unit 51 to receive and send circularly polarized electromagnetic waves. At the same time, when the second radiator 521 is stable in the first state, the second radiator 521 can be used as a housing bracket of the electronic device 100, and the housing bracket can remain stable in the first state, thereby adding new functions and new appearance effects to the electronic device 100.

[0145] In some embodiments, the rotating shaft 80 has a first damping, that is, the user needs to apply a torque greater than the first damping to rotate the second radiator 521. The present application does not limit the size of the first damping, as long as the size of the first damping is greater than the gravity torque of the second radiator 521. Among them, the gravity torque of the second radiator 521 refers to the size of the torque of the second radiator 521 rotating around the rotating shaft 80 under the action of gravity when the damping of the rotating shaft 80 is zero. As a result, the process of the user rotating the second radiator 521 is smooth, improving the user experience. At the same time, the rotating shaft 80 has a certain damping, which can prevent the second radiator 521 from being damaged due to frequent rotation during the movement of the electronic device 100, thereby extending the service life of the second radiator 521. Exemplarily, the range of the first damping is 0.01N·m-0.03N·m.

[0146] Similarly, when the protrusion 80a is used to snap into the second groove a2 so that the second radiator 521 and the shell 30 are stably at a preset angle r, the user also needs to apply a torque greater than the second preset torque to make the protrusion 80a disengage from the second groove a2, and the second radiator 521 also disengages from the first state and gradually switches to the second state.

[0147] The magnitude of the second moment can be adjusted according to the relative roughness between the convex portion 80a and the second groove a2, the material properties of the convex portion 80a and the second groove a2, the size, etc. For example, the greater the relative roughness between the convex portion 80a and the second groove a2, the greater the second moment, and the smaller the relative roughness between the convex portion 80a and the second groove a2, the smaller the second moment. During manufacturing, the magnitude of the second moment can be determined by experimental testing, and this application does not limit this. Exemplarily, the second preset moment is greater than 0.03N·m.

[0148] See also Fig.14 , Fig.14This is a schematic diagram of the cross-sectional structure of an electronic device 100 provided in some other embodiments of the present application, wherein a first connection portion c1 is provided on the housing 30, and a second connection portion c2 is provided on the second radiator 521; when the second radiator 521 is in the second state, the first connection portion c1 and the second connection portion c2 are connected. In other words, the first connection portion c1 and the second connection portion c2 are connected only when the second radiator 521 is in the second state, and when the second radiator 521 leaves the second state, the connection relationship between the first connection portion c1 and the second connection portion c2 is also released.

[0149] In this way, when the second radiator 521 is in the second state, it is both rotationally connected to the shell 30 and connected through the first connection part c1 and the second connection part c2. The two connection points are combined together, so that the second radiator 521 is stably connected to the shell 30 in the second state, avoiding damage to the second radiator 521 due to frequent rotation when the user moves the electronic device 100, thereby increasing the service life of the second radiator 521.

[0150] The present application does not limit the materials of the first connection part c1 and the second connection part c2. In some embodiments, the first connection part c1 is made of a magnet and the second connection part c2 is made of a metal material. Thus, the second radiator 521 is adsorbed on the housing 30 by magnetic attraction in the second state, and the connection is stable.

[0151] In some other embodiments, both the first connection portion c1 and the second connection portion c2 include conductive materials. Thus, the second radiator 521 can be electrically connected to other components in the electronic device 100 through the first connection portion c1 in the second state.

[0152] The present application does not limit the structure of the second connection portion c2. Exemplarily, the second connection portion c2 includes a pogo pin, so that the structure is simple.

[0153] The present application does not limit the structure of the first connecting portion c1. Fig.15 , Fig.15 The schematic diagram of the cross-sectional structure of the electronic device 100 provided in some embodiments of the present application, the first connection portion c1 includes: a card slot c11, and the shape of the second connection portion c2 is adapted to the shape of the card slot c11. Therefore, in the second state, at least part of the second connection portion c2 is located in the card slot c11, which can reduce the thickness of the electronic device 100 and improve the compactness of the structure of the electronic device 100.

[0154] In some embodiments, see Fig.16 , Fig.16 This is a schematic cross-sectional structural diagram of an electronic device 100 provided in some other embodiments of the present application. The electronic device 100 further includes a ground plate 2 , and the ground plate 2 is electrically connected to the first connection portion c1 .

[0155] In this way, when the first connection portion c1 includes a conductive material, the second antenna unit 52 can be grounded through the first connection portion c1 when the second radiator 521 is in the second state, without setting a separate grounding point, so that the overall structure of the electronic device 100 is more compact.

[0156] See also Fig.17 and Fig.18 , Fig.17 Schematic diagram of the three-dimensional structure of an electronic device 100 provided in some embodiments of the present application, Fig.18 for Fig.17 A partial cross-sectional structural diagram of an electronic device 100 is provided, in which the second antenna unit 52 further includes a reflector 523 for reflecting electromagnetic waves, and the reflector 523 is arranged on a side of the second radiator 521 away from the first radiator 511 .

[0157] In this way, the reflector 523 can reflect the electromagnetic waves on the side away from the first radiator 511 toward the side close to the first radiator 511, so that they are superimposed with the electromagnetic waves emitted by the first radiator 511, thereby enhancing the directivity of the antenna unit formed by the first antenna unit 51 and the second antenna unit 52 and improving the gain of the antenna unit.

[0158] In some embodiments, the reflector 523 is disposed on the side opposite to the maximum radiation direction of the second radiator 521. In this way, the reflector 523 can reflect the electromagnetic waves opposite to the maximum radiation direction of the second radiator 521 toward the maximum radiation direction of the second radiator 521, so that the electromagnetic waves are superimposed with the electromagnetic waves in the maximum radiation direction of the second radiator 521, thereby enhancing the directivity of the antenna and improving the gain of the second antenna unit 52.

[0159] When the maximum radiation direction of the second radiator 521 is close to the first radiator, Fig.17 As shown, Fig.17 The direction indicated by the middle arrow X1 is the maximum radiation direction of the second radiator 521 .

[0160] The present application does not limit the material of the reflector 523, as long as the reflector 523 can reflect the electromagnetic waves directed toward the reflector 523 in the opposite direction. Exemplarily, the material of the reflector 523 includes metal, dielectric or other materials with high reflectivity.

[0161] The present application does not limit the structure of the reflector 523, as long as a portion of the reflector 523 is located on a side of the second radiator 521 away from the first radiator 511. Exemplarily, the reflector 523 is in the shape of a plate or a block.

[0162] In the above embodiment, the structure of the electronic device 100 is described when the second radiator 521 is in the first state and the second antenna unit 52 cooperates with the first antenna unit 51 to achieve circularly polarized electromagnetic reception and transmission.

[0163] Since the second radiator 521 is located outside the housing 30, its width is not limited by the thickness of the electronic device 100. Therefore, by increasing the width of the second radiator 521, the second antenna unit 52 can have a larger working bandwidth, or even achieve ultra-wideband, so as to be compatible with more working frequency bands.

[0164] See also Fig.19 , Fig.19 The cross-sectional structure diagram of the electronic device 100 provided in some other embodiments of the present application, the electronic device 100 further includes: a first combiner 90a, a first tuning switch circuit 90c, a processor (or application processor) (Application Process, AP) 00 ( Fig.19 The first RF module 61 and the second RF module 62 are not shown), the second antenna unit 52 is connected to the first combiner 90a, and the first combiner 90a is electrically connected to the first RF module 61 and the second RF module 62. The first RF module 61, the second RF module 62, and the first tuning switch circuit 90c are all electrically connected to the processor 00.

[0165] The processor 00 is used to control the first RF module 61 to transmit the first RF signal to the second antenna unit 52 when the second radiator 521 is in the first state.

[0166] The processor 00 is further configured to control the second RF module 62 to transmit the first RF signal to the second antenna unit 52 when the second radiator 521 is in the second state.

[0167] When the second radiator 521 is in the second state, the first tuning switch circuit 90c is electrically connected to the second antenna unit 52, and the processor 00 is used to adjust the resonant frequency of the second antenna unit 52 through the first tuning switch circuit 90c according to the second radio frequency signal, so that the resonant frequency of the second antenna unit 52 is within the frequency band of the second radio frequency signal. The electromagnetic wave used when the first radio frequency signal is transmitted in space is a circularly polarized electromagnetic wave.

[0168] The frequency band and application scenario of the first radio frequency signal are the same as described above and will not be repeated here.

[0169] The present application does not limit the frequency band of the second radio frequency signal. Exemplarily, the frequency band of the second radio frequency signal includes a cellular signal frequency band, a WIFI signal frequency band, a Bluetooth signal frequency band, and the like.

[0170] Among them, the frequency bands supported by cellular signals include but are not limited to B1 (1920MHz-2170MHz), B3 (1710MHz-1880MHz), B34 (2010MHz-2025MHz), B39 (1880MHz-1920MHz) and other frequency bands. The frequency band supported by Bluetooth signals is 2.4GHz. The frequency bands supported by WIFI signals include 2.4GHz, 5GHz, 6GHz and other frequency bands. Among them, when the frequency band used by WIFI signals is 2.4GHz, WIFI signals and Bluetooth signals can use the same RF module to receive and send signals.

[0171] In this way, the second antenna unit 52 can not only receive and send the first radio frequency signal together with the first antenna unit 51 when the second radiator 521 is in the first state. The second antenna unit 52 can also receive and send the second radio frequency signal when the second radiator 521 is in the second state. As a result, the function of the second antenna unit 52 is increased, and the second antenna unit 52 is reused. At the same time, using the second antenna unit 52 to receive and send the second radio frequency signal when the second radiator 521 is in the second state is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal inside the electronic device 100 outside the electronic device 100, so that other antenna units inside the electronic device 100 have a larger size design space, thereby improving the performance of other antenna units inside the electronic device 100.

[0172] The present application does not limit the electrical connection method between the first combiner 90a and the first tuning switch circuit 90c and the second antenna unit 52. Fig.19 The electronic device 100 includes a first groove a1, a rotating shaft 80 disposed in the first groove a1, a first connecting portion c1, and a second connecting portion c2 as an example for description. The rotating shaft 80, the first connecting portion c1, and the second connecting portion c2 all include conductive materials. At this time, the first combiner 90a can be electrically connected to the second radiator 521 through the rotating shaft 80, and the first tuning switch circuit 90c can be connected to the second radiator 521 in the second state through the first connecting portion c1.

[0173] Meanwhile, when the electronic device 100 further includes a first connecting device b1, a feeding device 1 ( Fig.19 When the first connector 100 is electrically connected to the rotating shaft 80 through the first connector b1, the first combiner 90a can also reuse the first connector b1 to be electrically connected to the second radiator 521, thereby improving the space utilization of the electronic device 100.

[0174] The present application does not limit the locations of the first RF module 61, the second RF module 62, the processor 00, the first combiner 90a, and the first tuning switch circuit 90c in the electronic device 100. Exemplarily, the first RF module 61, the second RF module 62, the processor 00, the first combiner 90a, and the first tuning switch circuit 90c are all disposed on the circuit board 23.

[0175] The present application does not limit the structure of the first tuning switch circuit 90c, as long as the first tuning switch circuit 90c can adjust the resonant frequency of the second antenna unit 52. Exemplarily, the first tuning switch circuit 90c includes a tuning switch and a plurality of tuning circuits electrically connected to the tuning switch. The first tuning switch circuit 90c adjusts the resonant frequency of the second antenna unit 52 by switching between the plurality of tuning circuits through the tuning switch.

[0176] In some embodiments, see Fig. 20 , Fig. 20 Schematic diagram of the circuit structure corresponding to the electronic device 100 provided in some other embodiments of the present application. The electronic device 100 also includes a modulator 70. The processor 00 can control the first tuning switch circuit 90c to adjust the resonant frequency of the second antenna unit 52 when the second radiator 521 is in the second state, and the processor 00 can also control the first RF module 61 and the second RF module 62 to transmit the corresponding RF signal to the second antenna unit 52 according to the user's selection.

[0177] The function of the modulator 70 is the same as described above and will not be repeated here.

[0178] exist Fig. 20 In the provided electronic device 100, when the user needs to send a first RF signal, the second radiator 521 is rotated to the first state, the processor 00 controls the first RF module 61 to transmit the first RF signal to the modulator 70, the modulator 70 decomposes the first RF signal into two signals and sends them to the first combiner 90a and the first antenna unit 51 respectively, and the first combiner 90a transmits the first RF signal to the second antenna unit 52. At this time, the resonant frequency of the second antenna unit 52 is within the frequency band of the second RF signal. Thus, the transmission of the first RF signal is realized. The reception of the second RF signal is the reverse process of the transmission of the second RF signal.

[0179] When the user needs to send a second RF signal, after rotating the second radiator 521 to the second state, the processor 00 turns on the second RF module 62, and the second RF module 62 sends the second RF signal to the first combiner 90a, and the first combiner 90a transmits the second RF signal to the second antenna unit 52. At the same time, the processor 00 also controls the first tuning switch circuit 90c to adjust the resonant frequency of the second antenna unit 52 to the frequency band of the second RF signal. Thus, the sending of the second RF signal is realized. The reception of the second RF signal is the reverse process of the sending of the second RF signal.

[0180] In some embodiments, Fig.19 On the basis of the provided electronic device 100, the electronic device 100 further includes: a third RF module 63, the third RF module 63 is electrically connected to the processor 00, and the third RF module 63 is electrically connected to the first combiner 90a;

[0181] The processor 00 is further configured to control the third RF module 63 to transmit a third RF signal to the second antenna unit 52 when the second radiator 521 is in the second state;

[0182] The processor 00 is further configured to control the first tuning switch circuit 90c to adjust the resonant frequency of the second antenna unit 52 according to the third radio frequency signal, so that the resonant frequency of the second antenna unit is within the frequency band of the third radio frequency signal.

[0183] The present application does not limit the frequency band of the third radio frequency signal. Exemplarily, the frequency band of the third radio frequency signal includes a cellular signal frequency band, a WIFI signal frequency band, a Bluetooth signal frequency band, and the like.

[0184] In this way, the second antenna unit 52 can not only receive and send the first radio frequency signal together with the first antenna unit 51 when the second radiator 521 is in the first state. The second antenna unit 52 can also receive and send the second radio frequency signal and the third radio frequency signal when the second radiator 521 is in the second state. Thus, the function of the second antenna unit 52 is increased, and the second antenna unit 52 is reused. At the same time, using the second antenna unit 52 to receive and send the second radio frequency signal and the third radio frequency signal when the second radiator 521 is in the second state is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal and the third radio frequency signal inside the electronic device 100 outside the electronic device 100, so that other antenna units inside the electronic device 100 have a larger size design space, thereby improving the performance of other antenna units inside the electronic device 100.

[0185] Correspondingly, in some embodiments, see Fig.21 , Fig.21Schematic diagram of the circuit structure corresponding to the electronic device 100 provided in some other embodiments of the present application. The electronic device 100 also includes a modulator 70. The processor 00 can control the first tuning switch circuit 90c to adjust the resonant frequency of the second antenna unit 52 when the second radiator 521 is in the second state, and the processor 00 can also control the first RF module 61, the second RF module 62 and the third RF module 63 to transmit the corresponding RF signal to the second antenna unit 52 according to the user's selection. At this time, the steps for transmitting the third RF signal can refer to the steps for transmitting the second RF signal.

[0186] The above embodiment illustrates the structure of the electronic device 100 and the corresponding circuit structure when the second antenna unit 52 is reused. It is understandable that in some other embodiments, the electronic device 100 can reuse the first antenna unit 51 and the second antenna unit 52 at the same time.

[0187] The structure of the electronic device 100 when the first antenna unit 51 and the second antenna unit 52 are multiplexed to the first RF module 61 , the second RF module 62 and the third RF module 63 will be described below.

[0188] See also Fig. 22 , Fig. 22 This is a schematic diagram of the circuit structure of the electronic device provided in some embodiments of the present application. Fig.21 Based on the provided electronic device 100, the electronic device 100 further includes a second combiner 90b and a second tuning switch circuit 90d.

[0189] The first antenna unit 51 is electrically connected to the second combiner 90b, and the second combiner 90b is electrically connected to the first RF module 61, the second RF module 62 and the third RF module 63; the first RF module 61, the second RF module 62, the third RF module 63 and the second tuning switch circuit 90d are all electrically connected to the processor 00.

[0190] The processor 00 is configured to control the first RF module 61 to transmit a first RF signal to the first antenna unit 51 when the second radiator 521 is in the first state.

[0191] The processor 00 is further configured to control the second RF module 62 to transmit a second RF signal to the first antenna unit 51 when the second radiator 521 is in the second state.

[0192] The processor 00 is further configured to control the third RF module 63 to transmit a third RF signal to the first antenna unit 51 when the second radiator 521 is in the second state.

[0193] Among them, the second tuning switch circuit 90d is electrically connected to the first antenna unit 51; when the second radiator 521 is in the first state, the processor 00 adjusts the resonant frequency of the first antenna unit 51 through the second tuning switch circuit 90d according to the first RF signal, so that the resonant frequency of the first antenna unit 51 is within the frequency band of the first RF signal.

[0194] The processor 00 is further configured to adjust the resonant frequency of the first antenna unit 51 through the second tuning switch circuit 90d according to the second RF signal, so that the resonant frequency of the first antenna unit 51 is within the frequency band of the second RF signal. The processor 00 is further configured to adjust the resonant frequency of the first antenna unit 51 through the second tuning switch circuit 90d according to the third RF signal, so that the resonant frequency of the first antenna unit 51 is within the frequency band of the third RF signal. At this time, the electronic device 100 also includes a modulator 70.

[0195] Therefore, the first antenna unit 51 can not only receive and send the first radio frequency signal together with the second antenna unit 52 when the second radiator 521 is in the first state. The first antenna unit 51 can also receive and send the second radio frequency signal and the third radio frequency signal when the second radiator 521 is in the second state. Therefore, the function of the first antenna unit 51 is increased, and the reuse of the first antenna unit 51 is realized. At the same time, using the first antenna unit 51 to receive and send the second radio frequency signal and the third radio frequency signal is equivalent to setting the radiator of the antenna unit originally used for receiving and sending the second radio frequency signal and the third radio frequency signal inside the electronic device 100 on the first antenna unit 51, reducing the number of antennas inside the electronic device 100, so that other antenna units inside the electronic device 100 have a larger size design space, thereby improving the performance of other antenna units inside the electronic device 100.

[0196] exist Fig. 22 In the provided electronic device 100, the steps of using the second antenna unit 52 to transmit the second RF signal or the third RF signal are the same as described above, and will not be repeated here. When the user uses the second antenna unit 52 and the first antenna unit 51 to transmit the first RF signal, Fig. 22 An electronic device 100 is provided with Fig.21 Compared with the electronic device 100 provided, the only difference is that when the first RF signal is transmitted between the first RF module 61 and the first antenna unit 51, the first RF module 61 needs to pass through the second combiner 90b first.

[0197] When the user needs to use the first antenna unit 51 to send the second RF signal, the processor 00 turns on the second RF module 62, and the second RF module 62 sends the second RF signal to the second combiner 90b, and the second combiner 90b transmits the second RF signal to the first antenna unit 51. At the same time, the processor 00 also controls the second tuning switch circuit 90d to adjust the resonant frequency of the first antenna unit 51 to the frequency band of the second RF signal. Thus, the first antenna unit 51 realizes the transmission of the second RF signal. The reception of the second RF signal by the first antenna unit is the reverse process of the transmission of the second RF signal.

[0198] The steps of using the first antenna unit 51 to send and receive the third radio frequency signal may refer to the steps of using the first antenna unit 51 to send and receive the second radio frequency signal, which will not be repeated here.

[0199] In other embodiments, the first antenna unit 51 and the second antenna unit 52 may be multiplexed to the first RF module 61 and the second RF module 62. In this case, the steps of using the first antenna unit 51 to receive and send the first RF signal and the second RF signal are the same as described above.

[0200] It is understandable that in some other embodiments, when the first antenna unit 51 is reused, the second antenna unit 52 is only used to transmit the first radio frequency signal. At this time, the corresponding structure and circuit structure diagram of the electronic device 100 can refer to the above embodiment, which will not be repeated here.

[0201] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0202] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
