Corresponding multiple communication antennas are provided inside the electronic device. The coexistence of the satellite communication antenna and the existing communication antennas in the electronic device is an important condition for the electronic device to have both satellite communication and other communication functions. Summary of the Invention
[0004] Embodiments of this application provide an electronic device for solving the problem of the coexistence of the satellite communication antenna and the existing communication antennas in the electronic device.
[0005] To achieve the above object, this application adopts the following technical solutions:
[0006] In the first aspect of the embodiments of the present application, an electronic device is provided. The electronic device can be a single-screen electronic device or a foldable-screen electronic device. The electronic device includes a rectangular frame, a first antenna radiator, a second antenna radiator, a third antenna radiator, a first radio frequency module, a second radio frequency module, and a first selection switch. The frame includes a first position, a second position, a third position, a fourth position, and a fifth position arranged in sequence. The second position is located on the first side of the frame, and the fourth position is located on the second side of the frame. The first side intersects the second side. The frame has slits or ground terminals provided at the first position, the second position, the third position, the fourth position, and the fifth position. The first antenna radiator includes a conductive portion between the first position and the second position of the frame and a first feeding terminal; the second antenna radiator includes a conductive portion between the second position and the third position of the frame and a second feeding terminal; the third antenna radiator includes a conductive portion between the fourth position and the fifth position of the frame and a third feeding terminal; the first radio frequency module includes a radio frequency output terminal, and the radio frequency output terminal is coupled to the first feeding terminal; the first radio frequency module is, for example, a satellite communication module, and the transmission power of the radio frequency output terminal is greater than or equal to 34 dBm; the second radio frequency module is, for example, a cellular communication module, a BT communication module, an NL communication module, a WiFi communication module, or a GPS communication module, etc. The first selection switch includes a first fixed terminal, a first control terminal, a first selection terminal, and a second selection terminal. The first selection terminal is coupled to the second feeding terminal, the second selection terminal is coupled to the third feeding terminal, the first fixed terminal is coupled to the second radio frequency module, and the first control terminal is used to receive a control signal indicating whether the first radio frequency module emits a signal; the first selection switch is used to connect the first fixed terminal to one of the first selection terminal and the second selection terminal under the control of the control signal.
[0007] For the electronic device provided in the embodiments of the present application, the second radio frequency module is matched with a switchable second antenna radiator and third antenna radiator. When the first radio frequency module does not work, the second radio frequency module is connected to the second antenna radiator. When the first radio frequency module works, the second radio frequency module is connected to the third antenna radiator. And there is a third position between the third antenna radiator and the first antenna radiator. The third antenna radiator is located on the side away from the first antenna radiator of the second antenna radiator. Therefore, the isolation degree between the third antenna radiator and the first antenna radiator is greater than the isolation degree between the second antenna radiator and the first antenna radiator. Then, when the first radio frequency module works, the second radio frequency module switches to be connected to the third antenna radiator with a large isolation degree, which can reduce the energy of the transmission power of the first antenna radiator coupled to the link where the second radio frequency module is located, so as to reduce the risk of device damage on the link where the second radio frequency module is located, thereby achieving the purpose of coexistence of the first antenna radiator, the second antenna radiator, and the third antenna radiator in the electronic device.
[0008] In a possible implementation, the first control terminal is coupled to the first radio frequency module. In this way, the first selection switch is directly and only controlled by the first radio frequency module. The switching response speed of the first selection switch is fast and the fast switching time is short, which can improve the startup speed of the first radio frequency module.
[0009] In a possible implementation, the first selection switch is specifically configured to connect the first fixed terminal to the first selection terminal when the control signal indicates that the first radio frequency module does not transmit a signal, and connect the first fixed terminal to the second selection terminal when the control signal indicates that the first radio frequency module transmits a signal. When the first radio frequency module is not working, the second radio frequency module communicates through the second antenna radiator with strong top radiation ability. When the first radio frequency module is working, the second radio frequency module communicates through the third antenna radiator with good isolation. It can improve the communication effect of the electronic device on the basis of meeting the coexistence of multiple communication antennas.
[0010] In a possible implementation, the length of the frame from the fourth position to the second position is greater than or equal to 10 mm. By setting the length of the frame from the fourth position to the second position to be above 10 mm, the isolation requirement between the first antenna radiator and the third antenna radiator can be met.
[0011] In a possible implementation, the isolation between the third antenna radiator and the first antenna radiator is greater than or equal to 20 dB. By setting the isolation between the third antenna radiator and the first antenna radiator to be above 20 dB, the requirement that the energy of the transmitted power of the first antenna radiator coupled to the link where the third antenna radiator is located is not sufficient to damage the devices on the link where the second radio frequency module is located can be met.
[0012] In a possible implementation, the operating frequency band of the first antenna radiator is the satellite communication frequency band, and the satellite communication includes at least one of satellite short message, satellite phone, and satellite Internet access.
[0013] In a possible implementation, the operating frequency bands of the second antenna radiator and the third antenna radiator include the Bluetooth communication frequency band, the XingFlash communication frequency band, the mobile hotspot communication frequency band, the global positioning system communication frequency band, or the cellular communication frequency band. The second antenna radiator can be applicable to multiple non-satellite communication frequency bands.

[0018] In a possible implementation, the third antenna radiator includes a first grounding end that is close to the fifth position, and the third feeding end is away from the first grounding end. This is a setting method with simple structure and excellent performance.
[0019] In a possible implementation, when the third antenna radiator is used as a global positioning system antenna, the upper hemisphere radiation efficiency is greater than or equal to -10 dB. In this way, as an alternative antenna to the second antenna radiator, the third antenna radiator has the upper hemisphere radiation ability required for a GPS communication antenna to provide reliable positioning accuracy.
[0020] In a possible implementation, the second antenna radiator includes a third open end that is close to the second position, and the second feeding end is close to the third open end. This is a setting method with simple structure and excellent performance.
[0021] In a possible implementation, the second antenna radiator includes a fourth open end that is close to the third position, and the second feeding end is away from the fourth open end. This is a setting method with simple structure and excellent performance.
[0022] In a possible implementation, the second antenna radiator includes a second grounding end that is close to the third position, and the second feeding end is away from the second grounding end. This is a setting method with simple structure and excellent performance.
[0023] In a possible implementation, the upper hemisphere radiation efficiency of the second antenna radiator is greater than or equal to -7 dB. In this way, the second antenna radiator can have the top radiation ability required for a GPS communication antenna.
[0024] In a possible implementation, the first antenna radiator includes a fifth open end that is close to the second position, and the first feeding end is close to the fifth open end. This is a setting method with simple structure and excellent performance.
[0025] In a possible implementation, the first antenna radiator includes a sixth open end that is close to the first position, and the first feeding end is away from the sixth open end. This is a setting method with simple structure and excellent performance.
[0026] In a possible implementation, the first antenna radiator includes a third grounding end, the third grounding end is close to the fifth position, and the first feeding end is far from the third grounding end. This is a setting method with simple structure and excellent performance.
[0027] In a possible implementation, the second RF module is configured to receive signals transmitted by the second antenna radiator and the third antenna radiator. The components in the receiving link have relatively low tolerance to power. Improving the isolation degree on the receiving link can more significantly reduce the risk of device damage.
[0028] In a possible implementation, the electronic device further includes a first amplifier circuit, and the first amplifier circuit is coupled between the first selection end and the second feeding end. The first amplifier circuit can separately process the RF signal on the link where the second antenna radiator is located to optimize the performance of the electronic device.
[0029] In a possible implementation, the electronic device further includes a second amplifier circuit, and the second amplifier circuit is coupled between the second selection end and the third feeding end. The second amplifier circuit can separately process the RF signal on the link where the third antenna radiator is located to optimize the performance of the electronic device.
[0030] In a possible implementation, the electronic device further includes a second selection switch and a third RF module; the second selection switch includes a second control end, a third selection end, a fourth selection end, and a second fixed end; the second selection end is coupled to the third selection end, the fourth selection end is coupled to the third RF module, the second control end is used to receive a control signal, and the second fixed end is coupled to the third antenna radiator; the second selection switch is used to connect one of the third selection end and the fourth selection end to the second fixed end under the control of the control signal.
[0031] By setting the second selection switch, when the first RF module is working, the third antenna radiator is used by the second RF module. When the first RF module is not working, the third antenna radiator is used by the third RF module. The third antenna radiator serves as the matching antenna radiator of the third RF module and at the same time as the alternative antenna of the second antenna radiator. It is possible to avoid making a separate alternative antenna for the second antenna radiator, thereby reducing the requirement for the space adequacy of the electronic device.
[0032] In a possible implementation, the frame further includes a sixth position, a seventh position, and an eighth position that are located between the first position and the fifth position and are arranged in sequence; the electronic device further includes a fourth antenna radiator, a fifth antenna radiator, a fourth radio frequency module, and a third selection switch; the fourth antenna radiator includes a conductive portion of the frame between the first position and the eighth position and a fourth feeding end, and the fifth antenna radiator includes a conductive portion of the frame between the sixth position and the seventh position and a fifth feeding end; the third selection switch includes a third fixed end, a third control end, a fifth selection end, and a sixth selection end, the fifth selection end is coupled to the fourth feeding end, the sixth selection end is coupled to the fifth feeding end, the third fixed end is coupled to the fourth radio frequency module, and the third control end is used to receive a control signal; the third selection switch is used to connect the third fixed end to one of the fifth selection end and the sixth selection end under the control of the control signal.
[0033] The fourth radio frequency module is configured with a switchable fourth antenna radiator and a fifth antenna radiator. When the first radio frequency module is not working, the fourth radio frequency module is connected to the fourth antenna radiator. When the first radio frequency module is working, the fourth radio frequency module is connected to the fifth antenna radiator. Since the fifth antenna radiator is located on the side of the fourth antenna radiator away from the first antenna radiator, the isolation between the fifth antenna radiator and the first antenna radiator is greater than the isolation between the fourth antenna radiator and the first antenna radiator. Then, when the first radio frequency module is working, the fourth radio frequency module is connected to the fifth antenna radiator with a large isolation, which can reduce the energy of the transmitted power of the first antenna radiator coupled into the link where the fourth radio frequency module is located, so as to reduce the risk of damage to the components on the link where the fourth radio frequency module is located, thereby achieving the purpose of coexistence of the first antenna radiator, the second antenna radiator, the third antenna radiator, the fourth antenna radiator, and the fifth antenna radiator in the electronic device.

When the first radio frequency module is working, the second radio frequency module is connected to the second antenna radiator. The second antenna radiator and the first antenna radiator are not arranged adjacent to each other. By adjusting the length of the frame between the second position and the third position, the isolation between the second antenna radiator and the first antenna radiator can be adjusted, so as to reduce the energy of the transmission power of the first antenna radiator coupled into the link where the second radio frequency module is located, thereby reducing the risk of damage to the devices on the link where the second radio frequency module is located, and achieving the purpose of coexisting the second antenna radiator and the first antenna radiator in the electronic device.

The foldable electronic device can be an electronic device with a folding function such as a mobile phone, a tablet computer, an e-reader, a laptop computer, a wearable device such as a watch, etc. Figure 1 The illustrated embodiment is described by taking a foldable mobile phone as an example.
[0073] As Figure 1 shown, the electronic device 100 may include a flexible display screen 110, a first frame 121, a first cover 122, a second frame 123, a second cover 124, and a rotating shaft 125.
[0074] In some embodiments, the first frame 121, the first cover 122, the second frame 123, and the second cover 124 may form a first housing 121' and a second housing 122' that support the flexible display screen 110. The flexible display screen 110 is disposed above at least one of the first housing 121' and the second housing 122'. The first cover 122 and the second cover 124 may be insulating back covers, for example, plastic back covers, glass back covers, ceramic back covers, leather back covers, etc.
[0075] The flexible display screen 110 can be highly flexible and bendable, providing users with a new interaction method based on the foldable characteristics. For example, the flexible display screen 110 can adopt any one of a liquid crystal flexible display (LCD), an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a flexible light-emitting diode (FLED) display screen, a quantum dot light-emitting diode (QLED) display screen, etc. The embodiments of the present application do not limit this.
[0076] The flexible display screen 110 can include a first display portion 111 corresponding to the first housing 121', a second display portion 112 corresponding to the second housing 122', and a foldable display portion 113 corresponding to the rotating shaft 125. The foldable display portion 113 can be connected between the first display portion 111 and the second display portion 112.
[0077] The rotating shaft 125 can be connected between the first housing 121' and the second housing 122'. Under the action of the rotating shaft 125, the first housing 121' and the second housing 122' can approach or move away from each other. Correspondingly, the first display portion 111 and the second display portion 112 of the flexible display screen 110 can approach or move away from each other, so that the flexible display screen 110 can be folded or unfolded to realize the opening and closing function of the electronic device 100.
[0078] The first frame 121 can surround the outer periphery of the first cover 122, and at least part of the first frame 121 can also surround the outer periphery of the first display portion 111. The first display portion 111 can be arranged in parallel and spaced apart from the first cover 122, and the first display portion 111 and the first cover 122 can be located on both sides of the first frame 121. The spaced space between the first display portion 111 and the first cover 122 can be used to arrange devices such as antennas and circuit board assemblies of the foldable electronic device 100.
[0079] In an embodiment provided by the present application, the first frame 121 and the first cover 122 may be two parts of the housing of the foldable electronic device 100. The first frame 121 and the first cover 122 may be connected, and the form of this connection may not belong to assembly methods such as snap connection, adhesion, welding, riveting, clearance fit, etc. The connection relationship between the first frame 121 and the first cover 122 is usually difficult to be separated. In another embodiment provided by the present application, the first frame 121 and the first cover 122 may be two different components. By assembling the first frame 121 and the first cover 122 together, the first housing 121' of the foldable electronic device 100 can be formed.
[0080] The structural relationship between the second frame 123 and the second cover 124 may be the same as that between the first frame 121 and the first cover 122, and will not be elaborated here. In addition, the first cover 122 and the second cover 124 may be insulating back covers, such as plastic back covers, glass back covers, ceramic back covers, leather back covers, etc.
[0081] In some embodiments, the electronic device 100 further includes an antenna radiator ( Figure 1 not shown in the figure). The form of the antenna radiator may be an antenna form based on a flexible printed circuit (FPC), an antenna form based on laser-direct-structuring (LDS), or a microstrip disk antenna (MDA), etc. In other embodiments, the antenna radiator may also adopt a transparent structure embedded in the display screen of the electronic device 100, so that the antenna radiator is a transparent antenna unit embedded in the display screen of the electronic device 100.
[0082] The electronic device 100 may further include a printed circuit board (PCB) (not shown in the figure). The PCB is disposed in the cavity formed by the cover for carrying electronic components such as radio frequency modules. In some embodiments, a metal layer may be provided on the PCB. The metal layer can be used for grounding the electronic components carried on the PCB, and can also be used for grounding other components such as a bracket antenna and a frame antenna. The metal layer can be used as the floor, or ground plane, or grounding layer of the electronic device 100. Of course, the electronic device 100 may also have other floors / ground planes / grounding layers.
[0083] Currently, the electronic device 100 can already be compatible with Bluetooth (BT) communication function, NearLink (NL) communication function, mobile hotspot (WiFi) communication function, global positioning system (GPS) communication function, and cellular network (CN) function, and antenna radiators corresponding to the above functions are provided inside the electronic device 100.
[0084] However, with the rise of mobile phone satellite communication, people's actual usage demands for mobile phone satellite communication are getting stronger and stronger, and satellite communication antennas have developed from novelty to common use. However, since satellite communication is for long-distance communication and the transmission power is relatively large during the satellite communication process, if the transmission power is coupled to other communication links, it will cause damage to the devices on other communication links.
[0085] To implement the satellite communication function of the electronic device 100, it is sometimes inevitable to make the satellite communication function compatible with other communication functions. For example, to implement the satellite communication function, the satellite communication antenna needs to be able to align with the satellite. At this time, it is necessary to know the longitude and latitude of the electronic device 100 to assist in determining the relative position of the satellite communication antenna, and then the electronic device 100 moves to align with the satellite, so as to achieve a better communication effect. This requires the GPS communication function and the satellite communication function to coexist in the electronic device 100.
[0086] Figure 2 It is a schematic diagram of a satellite communication link and a GPS communication link provided by an embodiment of the present application.
[0087] As Figure 2 shown, the electronic device 100 includes a satellite communication link and a GPS communication link. The satellite communication link includes a satellite communication module, a power amplifier (PA), a filter, and a satellite communication antenna. The GPS communication link includes a GPS communication module, a filter, a low noise amplifier (LNA), and a GPS communication antenna.
[0088] The transmission power of the satellite communication antenna is relatively large. If the isolation degree between the satellite communication antenna and the GPS communication antenna does not meet the requirements, when the satellite communication antenna transmits power, the energy coupled to the GPS communication link will be relatively large, easily causing damage to devices such as filters and LNAs on the GPS communication link, affecting the reliability of the electronic device.
[0089] Therefore, if the electronic device 100 is to have a satellite communication function, it is necessary to make the isolation degree between the satellite communication antenna and other communication antennas meet the system design requirements to protect the devices on the communication link.
[0090] An embodiment of the present application provides an electronic device 100, which has both satellite communication functions and other communication functions, and the isolation degree between the satellite communication antenna and other communication antennas meets the system design requirements.
[0091] Figure 3 It is an architecture diagram of an electronic device provided by an embodiment of the present application.
[0092] An embodiment of the present application provides an electronic device 100. The electronic device 100 can be a straight-screen electronic device, or a curved-screen electronic device, or a foldable-screen electronic device. In the embodiments of the present application, only the straight-screen electronic device is taken as an example for illustration.
[0093] As Figure 3 shown, the electronic device 100 includes a rectangular frame 10, a first radio frequency module 31, a second radio frequency module 32, and a first selection switch 51.
[0094] The frame 10 can be a rectangular frame or a square frame. The shape of the frame 10 shown in Figure 3 is only for illustration and is not limited in any way. Of course, the electronic device 100 may include only one frame 10, in which case the electronic device 100 is a single-screen electronic device. The electronic device 100 may also include multiple frames 10, in which case the electronic device 100 is a multi-screen electronic device, such as a foldable electronic device. The embodiment of the present application does not limit the form of the electronic device 100, and the forms of the electronic device 100 in the related art are all applicable to the embodiment of the present application.
[0095] The frame 10 includes a first position 11, a second position 12, a third position 13, a fourth position 14, and a fifth position 15 arranged in sequence along its extending direction. The second position 12 is located on the first side s1 of the frame 10, and the fourth position 14 is located on the second side s2 of the frame 10. The first side s1 intersects the second side s2. By way of example, the first side s1 extends along the first direction X, the second side s2 extends along the second direction Y, the first side s1 is the short side of the electronic device 100, and the second side s2 is the long side of the electronic device 100. For example, taking the angle of the user's handhold as an example, the first side s1 is, for example, the top side of the electronic device 100, and the second side s2 is, for example, the side of the electronic device 100.
[0096] In the embodiments of the present application, the frame 10 has slits or grounding terminals provided at the first position 11, the second position 12, the third position 13, the fourth position 14, and the fifth position 15. It should be understood that the positions on the frame 10 mentioned in the embodiments of the present application are all point positions. If the slit has a certain length, the midpoint of the region between the two boundary ends of the slit is the position in the embodiments of the present application. For example, if the first position 11 is a slit, the midpoint of the continuous region of the slit is the first position 11 in the embodiments of the present application. If the grounding terminal extends for a certain distance, the midpoint of the region between the two boundary ends of the grounding terminal is the position in the embodiments of the present application. For example, if the third position 13 is a grounding terminal, the midpoint of the continuous region of the grounding terminal is the third position 13 in the embodiments of the present application.
[0097] The first antenna radiator ANT1 includes the conductive portion between the first position 11 and the second position 12 of the frame 10 and the first feeding terminal 21. For example, the frame 10 has a slit at the second position 12, and has a slit or a grounding terminal at the first position 11 ( Figure 3 illustrated by taking the frame 10 having a slit at the first position 11 as an example), and the first feeding terminal 21 is arranged close to the second position 12.
[0098] The second antenna radiator ANT2 includes the conductive portion between the second position 12 and the third position 13 of the frame 10 and the second feeding terminal 22. For example, the frame 10 has a slit at the second position 12, and has a slit or a grounding terminal at the third position 13 ( Figure 3 illustrated by taking the frame 10 having a grounding terminal at the third position 13 as an example), and the second feeding terminal 22 is arranged close to the second position 12.
[0099] The third antenna radiator ANT3 includes the conductive portion between the fourth position 14 and the fifth position 15 of the frame 10 and the third feeding terminal 23. For example, the frame 10 has a slit at the fourth position 14, and has a slit or a grounding terminal at the fifth position 15 ( Figure 3 illustrated by taking the frame 10 having a grounding terminal at the fifth position 15 as an example), and the third feeding terminal 23 is arranged close to the fourth position 14.
[0100] Among them, the conductive portion between the fourth position 14 and the third position 13 of the frame 10 can be used as a communication antenna for other functions or can be used as an isolation structure. In some embodiments, the conductive portion between the fourth position 14 and the third position 13 of the frame 10 is used as a communication antenna for other functions, and can be fed on the conductive portion between the fourth position 14 and the third position 13, or the conductive portion between the fourth position 14 and the third position 13 can be used as a parasitic radiator.
[0101] In some embodiments, the frame 10 is an insulating frame, such as a plastic frame. The first antenna radiator ANT1, the second antenna radiator ANT2, and the third antenna radiator ANT3 can be conductors attached to the non-appearance surface of the frame 10, such as an FPC antenna or an LDS antenna formed on the non-appearance surface of the frame 10 by laser ablation technology. In the embodiments of the present application, the non-appearance surface and the appearance surface are two opposite surfaces, and the appearance surface can be understood as the exposed surface that can be directly felt by the user. The non-appearance surface is the surface facing the inside of the electronic device and cannot be directly felt by the user.
[0102] In other embodiments, the frame 10 is a conductive frame, such as a metal frame. At least part of the conductive structure of the frame 10 can serve as the first antenna radiator ANT1, the second antenna radiator ANT2, and the third antenna radiator ANT3. There may be a gap between this part of the frame serving as the antenna radiator and other parts of the frame, so as to ensure a good radiation environment for the antenna radiator.
[0103] Among them, the antenna radiator: is a device in the antenna used to receive / transmit electromagnetic wave radiation. In some cases, "antenna" is narrowly understood as the radiator, which converts the guided wave energy from the transmitter into radio waves, or converts radio waves into guided wave energy, for radiating and receiving radio waves. The modulated high-frequency current energy (or guided wave energy) generated by the transmitter is transmitted to the transmitting radiator through the feeder line. The radiator converts it into electromagnetic wave energy of a certain polarization and radiates it in the required direction. The receiving radiator converts the electromagnetic wave energy of a certain polarization from a specific direction in space back into modulated high-frequency current energy and transmits it to the input end of the receiver through the feeder line.
[0104] Terminal: The "terminal" in the first terminal / second terminal / feeding terminal / grounding terminal of the antenna radiator should not be narrowly understood as an endpoint or end part that is physically disconnected from other radiators. It can also be considered as a certain point or a certain section on the continuous radiator. In one embodiment, the "terminal" can include the connection / coupling area on the antenna radiator that is coupled to other conductive structures. For example, the feeding terminal can be the coupling area on the antenna radiator that is coupled to the feeding structure or the feeding circuit (for example, the area facing a part of the feeding circuit), and for another example, the grounding terminal can be the connection / coupling area on the antenna radiator that is coupled to the grounding structure or the grounding circuit.
[0105] The first radio frequency module 31 includes a radio frequency output terminal, and the radio frequency output terminal is coupled to the first feeding terminal 21. Then, the first communication link is from the first radio frequency module 31 to the first antenna radiator ANT1.
[0106] The first selection switch 51 is configured to switch the second radio frequency module 32 to be connected to the second feeding terminal 22 or the third feeding terminal 23 according to a control signal indicating whether the first radio frequency module 31 (such as a satellite communication module) emits a signal. For example, the first selection switch 51 includes a first fixed terminal a1, a first control terminal c1, a first selection terminal b1, and a second selection terminal b2. The first selection terminal b1 is coupled to the second feeding terminal 22, the second selection terminal b2 is coupled to the third feeding terminal 23, the first fixed terminal a1 is coupled to the second radio frequency module 32, and the first control terminal c1 is configured to receive a control signal indicating whether the first radio frequency module emits a signal. The first selection switch 51 is configured to connect the first fixed terminal a1 to one of the first selection terminal b1 and the second selection terminal b2 under the control of the control signal. Then, the second communication link is from the second radio frequency module 32 through the first selection terminal b1 to the second antenna radiator ANT2, and the third communication link is from the second radio frequency module 32 through the second selection terminal b2 to the third antenna radiator ANT3.
[0107] In some embodiments, the control signal received by the first control terminal c1 is sent by a controller in the electronic device 100. After detecting that the first radio frequency module 31 emits a signal, the controller sends a control signal to the first control terminal c1.
[0108] In other embodiments, as Figure 3 shown, the first control terminal c1 is coupled to the first radio frequency module 31, and the first radio frequency module 31 directly sends a control signal to the first control terminal c1.
[0109] For example, the first radio frequency module 31 includes a general purpose input / output (GPIO) port or a mobile industry processor interface (MIPI), and the first radio frequency module 31 transmits a control signal to the first selection switch 51 through the above port or interface.
[0110] In the electronic device 100 provided by the embodiment of the present application, the first selection switch 51 controls the first radio frequency module 31 to change its working state only according to whether the first radio frequency module 31 emits a signal, and the first selection switch 51 synchronously switches the selection terminal. For example, the first selection switch 51 is specifically configured to connect the first fixed terminal a1 to the first selection terminal b1 when the control signal indicates that the first radio frequency module 31 does not emit a signal. When the control signal indicates that the first radio frequency module 31 emits a signal, the first fixed terminal a1 is connected to the second selection terminal b2. Or it can be understood that the first selection switch 51 defaults to connect the first fixed terminal a1 to the first selection terminal b1. When the first radio frequency module 31 emits a signal, the first selection switch 51 is controlled to switch to connect the first fixed terminal a1 to the second selection terminal b2. When the first radio frequency module 31 does not emit a signal, the first selection switch 51 is controlled to switch to the default state, and the first fixed terminal a1 is connected to the first selection terminal b1.
[0111] It should be understood that in the embodiment of the present application, the first selection switch 51 can be selected according to actual production or design. For example, as Figure 3 shown, the first selection switch 51 can be a single-pole double-throw (SPDT) switch. Or, for example, the first selection switch 51 can be a single-pole x-throw (SPXT) switch. The embodiment of the present application does not limit this, and only needs to ensure that the number of selection terminals of the first selection switch 51 is greater than the number of electronic components or radio frequency channels to be connected.
[0112] In some embodiments, the first radio frequency module 31 includes a radio frequency circuit and a radio frequency front-end module. When the radio frequency circuit works with the satellite, the transmission gain is greater than or equal to 22 dBm. After the radio frequency signal output by the radio frequency circuit is converted by the radio frequency front-end module, the transmission power of the first radio frequency module 31 from the radio frequency output terminal is greater than or equal to 34 dBm. That is, the transmission power of the test socket, test pad, and calibration point between the radio frequency output terminal and the first antenna radiator ANT1 is greater than or equal to 34 dBm, or the transmission power of the feeding elastic sheet of the first antenna radiator ANT1 is greater than or equal to 34 dBm, or the power of the first feeding end 21 of the first antenna radiator ANT1 is greater than or equal to 34 dBm, or the board-level conduction power of the first feeding end 21 of the first antenna radiator ANT1 is greater than or equal to 34 dBm.
[0113] For example, the transmit gains of the first RF module 31 during satellite acquisition are 22 dBm, 30 dBm, 32 dBm, 31 dBm, 37 dBm, 40 dBm, 42 dBm, 45 dBm, 47 dBm, 50 dBm, etc. The transmit powers at the RF output end are 34 dBm, 31 dBm, 37 dBm, 40 dBm, 42 dBm, 45 dBm, 47 dBm, 50 dBm, etc.
[0114] Exemplarily, the first RF module 31 is a satellite communication module. For example, the first RF module 31 is a satellite communication chip. Or, for example, the first RF module 31 is a package structure formed by co-packaging a satellite communication chip and a digital-to-analog circuit such as digital-to-analog conversion. Or, for another example, the first RF module 31 is a package structure formed by co-packaging a satellite communication chip and a RF front-end module. The satellite communication module is used for performing at least one of satellite short message communication, satellite phone communication, and satellite Internet communication.
[0115] Then, correspondingly, the first antenna radiator ANT1 coupled to the first RF module 31 is a satellite communication antenna. Exemplarily, the first antenna radiator ANT1 is a low-earth orbit satellite communication antenna. For example, the transmit frequency band of the low-earth orbit satellite communication antenna is 1.668 GHz - 1.675 GHz, and the receive frequency band of the low-earth orbit satellite communication antenna is 1.518 GHz - 1.525 GHz. Or, the first antenna radiator ANT1 is a Beidou satellite communication antenna. For example, the transmit frequency band of the Beidou satellite communication antenna is 1.615 GHz - 1.620 GHz, and the receive frequency band of the Beidou satellite communication antenna is 2.48 GHz - 2.5 GHz. Or, the first antenna radiator ANT1 is a Tiantong satellite communication antenna or a geostationary orbit satellite communication antenna. For example, the transmit frequency band of the Tiantong satellite communication antenna is 1.98 GHz - 2.0 GHz, and the receive frequency band of the Tiantong satellite communication antenna is 2.17 GHz - 2.2 GHz. Or, the first antenna radiator ANT1 is a medium-earth orbit satellite communication antenna with an operating frequency band of 4 GHz - 6 GHz.
[0116] The embodiment of the present application does not limit the specific structure of the first antenna radiator ANT1, as long as it meets the communication requirements of the first RF module 31 coupled thereto. In addition, the first antenna radiator ANT1 in the embodiment of the present application can be used to support at least one of satellite short message communication, satellite phone communication, and satellite Internet communication.
[0117] In some embodiments, the link where the second radio frequency module 32 is located is a receiving link, and the second radio frequency module 32 is configured to receive signals transmitted by the second antenna radiator ANT2 and the third antenna radiator ANT3. Of course, at the same moment, the second radio frequency module 32 can only receive the radio frequency signals transmitted by the second antenna radiator ANT2 or the third antenna radiator ANT3. Of course, the second radio frequency module 32 can also be configured to transmit signals to the second antenna radiator ANT2 and the third antenna radiator ANT3.
[0118] Exemplarily, the second radio frequency module 32 is used for communications other than satellite communications. For example, the board-level conduction power of the second feeding end 22 of the second antenna radiator ANT2 is less than or equal to 22'dBm, and the board-level conduction power of the third feeding end 23 of the third antenna radiator ANT3 is less than or equal to 22'dBm. Exemplarily, the operating frequency band of the second antenna radiator ANT2 may include at least some frequency bands in the cellular network, for example, the lower band (LB, 699 MHz - 960 MHz), the mid / high band (MHB, 1.71 GHz - 2.7 GHz), and the Sub-6G band. Or, exemplarily, the operating frequency band of the second antenna radiator ANT2 may include at least some frequency bands in the near communication (NC), for example, the BT band of 2.4 GHz - 2.48 GHz, the XingShan band of 2.4 GHz - 2.48 GHz, the WiFi band of 2.4 GHz - 2.48 GHz, and the GPS band of 1.56 GHz - 1.62 GHz.
[0119] Exemplarily, the second radio frequency module 32 is a BT communication module, and the operating frequency bands of the second antenna radiator ANT2 and the third antenna radiator ANT3 are the BT band. Or, exemplarily, the second radio frequency module 32 is an NL communication module, and the operating frequency bands of the second antenna radiator ANT2 and the third antenna radiator ANT3 are the XingShan band. Or, exemplarily, the second radio frequency module 32 is a WiFi communication module, and the operating frequency bands of the second antenna radiator ANT2 and the third antenna radiator ANT3 are the WiFi band. Or, exemplarily, the second radio frequency module 32 is a GPS communication module, and the operating frequency bands of the second antenna radiator ANT2 and the third antenna radiator ANT3 are the GPS band. Or, exemplarily, the second radio frequency module 32 is a cellular network communication module, and the operating frequency bands of the second antenna radiator ANT2 and the third antenna radiator ANT3 are the cellular network bands.
[0120] In the embodiments of the present application, the specific structures of the second antenna radiator ANT2 and the third antenna radiator ANT3 are not limited, and it is only necessary to meet the communication requirements of the second radio frequency module 32 coupled thereto. For example, if the second radio frequency module 32 is a GPS communication module, the structure of the second antenna radiator ANT2 should be able to meet the requirements of its satellite acquisition performance.
[0121] In the electronic device 100 provided by the embodiments of the present application, the second radio frequency module 32 is matched with a switchable second antenna radiator ANT2 and third antenna radiator ANT3. When the first radio frequency module 31 is not working, the second radio frequency module 32 is connected to the second antenna radiator ANT2. When the first radio frequency module 31 is working, the second radio frequency module 32 is connected to the third antenna radiator ANT3. Since the third antenna radiator ANT3 is located on the side of the second antenna radiator ANT2 away from the first antenna radiator ANT1, the isolation between the third antenna radiator ANT3 and the first antenna radiator ANT1 is greater than the isolation between the second antenna radiator ANT2 and the first antenna radiator ANT1. Then, when the first radio frequency module 31 is working, the second radio frequency module 32 is switched to be connected to the third antenna radiator ANT3 with a larger isolation, which can reduce the energy of the transmitted power of the first antenna radiator ANT1 coupled into the link where the second radio frequency module 32 is located, so as to reduce the risk of damage to the devices on the link where the second radio frequency module 32 is located, thereby achieving the purpose of coexistence of the first antenna radiator ANT1, the second antenna radiator ANT2, and the third antenna radiator ANT3 in the electronic device 100.
[0122] In some embodiments, the isolation between the third antenna radiator ANT3 and the first antenna radiator ANT1 is greater than or equal to 20 dB. For example, the isolation between the third antenna radiator ANT3 and the first antenna radiator ANT1 is 20 dB, 21 dB, 22 dB, 23 dB, 24 dB, 25 dB, 30 dB, 31 dB, 40 dB, etc.
[0123] Since the second radio frequency module 32 is connected to the third antenna radiator ANT3 when the first radio frequency module 31 transmits a signal. Then, by setting the isolation between the third antenna radiator ANT3 and the first antenna radiator ANT1 above 20 dB, it can meet the requirement that the energy of the transmitted power of the first antenna radiator ANT1 coupled into the link where the third antenna radiator ANT3 is located is not sufficient to damage the devices on the link where the second radio frequency module 32 is located.
[0124] Next, taking the first radio frequency module 31 as a satellite communication radio frequency module and the second radio frequency module 32 as a GPS communication module as an example, the electronic device 100 provided by the embodiments of the present application will be described in detail.
[0125] When the first radio frequency module 31 does not transmit a signal, the second radio frequency module 32 is connected to the second antenna radiator ANT2 through the first selection switch 51. The second antenna radiator ANT2 needs to have the top radiation ability required by the GPS communication antenna. For example, the second antenna radiator ANT2 is a GPS L1 antenna with good top radiation ability. By way of example, the upper hemisphere radiation efficiency of the second antenna radiator ANT2 is greater than or equal to -7 dB. For example, the upper hemisphere radiation efficiency of the second antenna radiator ANT2 is -7 dB, -6 dB, -5 dB, -4 dB, -3 dB, -2 dB, -1 dB.
[0126] When the first radio frequency module 31 transmits a signal, the second radio frequency module 32 is connected to the third antenna radiator ANT3 through the first selection switch 51. The third antenna radiator ANT3, as an alternative antenna to the second antenna radiator ANT2, needs to have the upper hemisphere radiation ability required by the GPS communication antenna to provide reliable positioning accuracy. For example, the upper hemisphere radiation efficiency of the third antenna radiator ANT3 when used as a GPS antenna is greater than or equal to -10 dB. For example, the upper hemisphere radiation efficiency of the third antenna radiator ANT3 when used as a GPS antenna is -10 dB, -9 dB, -8 dB, -7 dB, -6 dB, -5 dB, -4 dB, -3 dB, -2 dB, -1 dB.
[0127] In some embodiments, the first antenna radiator ANT1 is a Tiantong satellite communication antenna.
[0128] To meet the isolation requirement, the length of the frame 10 from the fourth position 14 to the second position 12 is greater than or equal to 20 mm. For example, the length of the frame 10 from the fourth position 14 to the second position 12 is 20 mm, 22 mm, 23 mm, 24 mm, 25 mm, 30 mm, 31′mm, 40 mm, 45 mm, etc.
[0129] By way of example, the first antenna radiator ANT1 is a Tiantong satellite communication antenna or a high-orbit satellite communication antenna, the second antenna radiator ANT2 is a GPS communication antenna, a Wifi communication antenna, a BT communication antenna, a StarFlash communication antenna or a cellular communication antenna, and the length of the frame 10 from the fourth position 14 to the second position 12 is greater than or equal to 20 mm.
[0130] Table 1 Comparison table of the frame lengths corresponding to the Tiantong satellite communication antenna
[0131]
[0132] The electronic device 100 provided by the embodiment of the present application includes a switchable second antenna radiator ANT2 and a third antenna radiator ANT3. The third antenna radiator ANT3 serves as an alternative antenna to the second antenna radiator ANT2. When the first antenna radiator ANT1 is working, the third antenna radiator ANT3 is working. When the first antenna radiator ANT1 is not working, the second antenna radiator ANT2 is working. As Figure 4A shown, if the electronic device 100 does not include the alternative third antenna radiator ANT3, when the working frequency of the first antenna radiator ANT1 is about 2 GHz and the working frequency of the second antenna radiator ANT2 is about 1.6 GHz, the isolation between the first antenna radiator ANT1 and the second antenna radiator ANT2 is about 9 dB or 15 dB. And as Figure 4B shown, if the electronic device 100 includes the alternative third antenna radiator ANT3, when the working frequency of the first antenna radiator ANT1 is about 2 GHz and the working frequency of the third antenna radiator ANT3 is about 1.6 GHz, the isolation between the first antenna radiator ANT1 and the third antenna radiator ANT3 can be increased to about 21 dB. As Figure 4C shown, if the electronic device 100 does not include the alternative third antenna radiator ANT3, the radiation efficiency of the first antenna radiator ANT1 is about -1 dB. And as Figure 4D shown, if the electronic device 100 includes the alternative third antenna radiator ANT3, the radiation efficiency of the first antenna radiator ANT1 can reach about -0.3 dB, and the radiation efficiency of the first antenna radiator ANT1 can be increased by about 0.7 dB. In addition, through simulation, it is found that the upper hemisphere ratio of the third antenna radiator ANT3 in the electronic device 100 provided by the embodiment of the present application can reach about 40%, which can provide reliable positioning accuracy.
[0133] Antenna radiation efficiency: It refers to the ratio of the power radiated by the antenna into space (i.e., the power effectively converted into electromagnetic waves) to the active power input to the antenna. Among them, the active power input to the antenna = the input power of the antenna - the loss power; the loss power mainly includes the return loss power, the ohmic loss power of the metal and / or the dielectric loss power. The radiation efficiency is a value that measures the radiation ability of the antenna. Metal loss and dielectric loss are both influencing factors of the radiation efficiency. Those skilled in the art can understand that efficiency is generally expressed as a percentage, and there is a corresponding conversion relationship between it and dB. The closer the efficiency is to 0 dB, the better the efficiency of the antenna is characterized.
[0134] In some other embodiments, the first antenna radiator ANT1 is a low-earth orbit satellite communication antenna.
[0135] To meet the isolation requirement, the length of the frame 10 from the fourth position 14 to the second position 12 is greater than or equal to 20 mm. For example, the length of the frame 10 from the fourth position 14 to the second position 12 is 20 mm, 22 mm, 23 mm, 24 mm, 25 mm, 30 mm, 31′mm, 40 mm, 45 mm, etc.
[0136] Exemplarily, as shown in Table 2, the first antenna radiator ANT1 is a low-earth orbit satellite communication antenna, the second antenna radiator ANT2 is a Wifi communication antenna, a BT communication antenna, or a XingShan communication antenna, and the length of the frame 10 from the fourth position 14 to the second position 12 is greater than or equal to 20 mm. When the second antenna radiator ANT2 is a GPS communication antenna or a cellular communication antenna, the length of the frame 10 from the fourth position 14 to the second position 12 is greater than or equal to 30 mm. For example, the length of the frame 10 from the fourth position 14 to the second position 12 is 30 mm, 32 mm, 33 mm, 34 mm, 31′mm, 40 mm, 45 mm, 50 mm, 52′mm, etc.

[0138]
[0139] The electronic device 100 provided by the embodiment of the present application includes a switchable second antenna radiator ANT2 and a third antenna radiator ANT3, and the third antenna radiator ANT3 serves as an alternative antenna for the second antenna radiator ANT2. When the first antenna radiator ANT1 is working, the third antenna radiator ANT3 is working. When the first antenna radiator ANT1 is not working, the second antenna radiator ANT2 is working. As Figure 5A shown, if the electronic device 100 does not include the alternative third antenna radiator ANT3, when the working frequency of the first antenna radiator ANT1 is about 1.7 Ghz and the working frequency of the second antenna radiator ANT2 is about 1.5 Ghz, the isolation between the first antenna radiator ANT1 and the second antenna radiator ANT2 is about 4 dB. And as Figure 5B shown, if the electronic device 100 includes the alternative third antenna radiator ANT3 and the working frequency of the third antenna radiator ANT3 is about 1.6 Ghz, the isolation between the first antenna radiator ANT1 and the third antenna radiator ANT3 can be increased to about 21 dB. As Figure 5C shown, if the electronic device 100 does not include the alternative third antenna radiator ANT3, the radiation efficiency of the first antenna radiator ANT1 is about -3 dB. And as Figure 5DAs shown, if the electronic device 100 includes an alternative third antenna radiator ANT3, the radiation efficiency of the first antenna radiator ANT1 can reach about -0.5 dB, and the radiation efficiency of the first antenna radiator ANT1 can be increased by about 2 dB - 3 dB.

[0156] In some other embodiments, as Figure 6B shown, the second antenna radiator ANT2 includes a third open end and a fourth open end. The third open end is close to the second position 12, the fourth open end is close to the third position 13, and the second feeding end 22 is close to the third open end and far from the fourth open end.
[0157] In some embodiments, as Figure 6A shown, the first antenna radiator ANT1 includes a fifth open end and a sixth open end. The fifth open end is close to the second position 12, the sixth open end is close to the first position 11, and the first feeding end 21 is close to the fifth open end and far from the sixth port.

[0159] Exemplarily, as Figure 6B shown, the third open end k3 of the second antenna radiator ANT2 is opposite to the fifth open end k5 of the first antenna radiator ANT1, but they do not contact.
[0160] In some embodiments, as Figure 6B shown, the first position 11 and the second position 12 are both located on the first side s1, the third position 13 is located at the corner, and the fourth position 14 and the fifth position 15 are both located on the second side s2.
[0161] The electronic device 100 provided by the embodiment of the present application internally coexists a satellite communication antenna and a GPS communication antenna that meet the isolation requirement. When using the satellite communication antenna, the GPS communication antenna can provide accurate real-time position information, improving the reliability of the user in a complex environment.
[0162] Figure 7A and Figure 7B is a topological schematic diagram of a radio frequency link provided by the embodiment of the present application.
[0163] In some embodiments, as Figure 7A shown, the first radio frequency module 31 includes a radio frequency output end O1, and the radio frequency output end O1 is coupled to the first antenna radiator ANT1. Exemplarily, the first radio frequency module 31 includes a radio frequency circuit and a radio frequency front-end module. The radio frequency front-end module can include, for example, one or more of devices such as an LNA, a PA, a filter, a transceiver, a coupler, and a duplexer.
[0164] In some embodiments, as Figure 7BAs shown, the second radio frequency module 32 includes a radio frequency circuit and does not include a radio frequency front-end module. The electronic device further includes a first amplification circuit, and the first amplification circuit is coupled between the first selection terminal b1 and the second feeding terminal (the second antenna radiator ANT2). For example, the first amplification circuit includes an LNA.
[0165] The electronic device further includes a second amplification circuit, and the second amplification circuit is coupled between the second selection terminal b2 and the third feeding terminal (the third antenna radiator ANT3). For example, the second amplification circuit includes an LNA.
[0166] The LNA can perform power compensation on the radio frequency signal lost from the first selection terminal b1 to the first fixed terminal a1, and the LNA can perform power compensation on the radio frequency signal lost from the second selection terminal b2 to the first fixed terminal a1. By performing power compensation on the link where the second antenna radiator ANT2 is located and the link where the third antenna radiator ANT3 is located respectively, the power loss on each respective link can be precisely combined for matching compensation, so as to improve the power compensation accuracy and reduce the influence of the loss of the first selection switch 51 on the performance of the second radio frequency module 32.
[0167] In some other embodiments, the second radio frequency module 32 includes a radio frequency circuit and a radio frequency front-end module. The radio frequency front-end module can include an LNA, for example.
[0168] By arranging an LNA at the first fixed terminal a1, the radio frequency signal lost from the first selection terminal b1 to the first fixed terminal a1 and the radio frequency signal lost from the second selection terminal b2 to the first fixed terminal a1 are power-compensated by the same LNA, which can reduce the number of LNAs and save area.
[0169] Figure 8A It is an architecture diagram of an electronic device provided by an embodiment of the present application. Figure 8B It is a topological schematic diagram of a radio frequency link provided by an embodiment of the present application.
[0170] In some embodiments, as Figure 8A shown, the frame 10 further includes a sixth position 16, a seventh position 17, and an eighth position 18 that are located between the first position 11 and the fifth position 15 and are arranged in sequence.
[0171] That is to say, the first position 11 to the eighth position 18 on the frame 10 are arranged in sequence. Of course, Figure 8AThe settings of the first position 11 to the eighth position 18 shown in the figure on the border 10 are only for illustration and are not subject to any limitation. For example, the first position 11 and the second position 12 are located on the first side s1, the third position 13 is located at the vertex, the fourth position 14 and the fifth position 15 are located on the second side s2, the sixth position 16 is located on the side opposite to the first side s1, and the seventh position 17 and the eighth position 18 are located on the side opposite to the second side s2.
[0172] The electronic device 100 further includes a fourth antenna radiator ANT4, a fifth antenna radiator ANT5, a fourth radio frequency module 34, and a third selection switch 53.
[0173] The fourth antenna radiator ANT4 includes a conductive portion of the border 10 between the first position 11 and the eighth position 18 and a fourth feeding end 24. By way of example, the border 10 has a slit or a grounding end provided at the eighth position 18 ( Figure 8A illustrated by taking the border 10 having a slit at the eighth position 18 as an example), and the fourth feeding end 24 is arranged close to the first position 11. For example, the fourth antenna radiator ANT4 includes a seventh opening end k7 and an eighth opening end k8. The seventh opening end k7 faces the first position 11, the eighth opening end k8 faces the eighth position, and the sixth opening end k6 of the first antenna radiator ANT1 and the seventh opening end k7 of the fourth antenna radiator ANT4 are arranged opposite to each other but in contact.
[0174] The fifth antenna radiator ANT5 includes a conductive portion of the border between the sixth position 16 and the seventh position 17 and a fifth feeding end 25. By way of example, the border 10 has a slit at the seventh position 17 and a slit or a grounding end provided at the sixth position 16 ( Figure 8A illustrated by taking the border 10 having a slit at the sixth position 16 as an example), and the fifth feeding end 25 is arranged close to the seventh position 17. For example, the fifth antenna radiator ANT5 includes a ninth opening end k9 and a tenth opening end k10. The ninth opening end k9 faces the seventh position 17, and the tenth opening end k10 faces the sixth position.
[0175] Wherein, the conductive portion of the border 10 between the seventh position 17 and the eighth position 18 can be used as a communication antenna for other functions or as an isolation structure.
[0176] The third selection switch 53 includes a third fixed terminal a3, a third control terminal c3, a fifth selection terminal b5, and a sixth selection terminal b6. The fifth selection terminal b5 is coupled to the fourth power feeding terminal 24, the sixth selection terminal b6 is coupled to the fifth power feeding terminal 25, and the third fixed terminal a3 is coupled to the fourth RF module 34. The third control terminal c3 is used to receive a control signal characterizing whether the first RF module 31 emits a signal. For example, the first RF module 31 is coupled to the third control terminal c3, and the first RF module 31 directly sends a control signal to the third control terminal c3.
[0177] The third selection switch 53 is used to connect the third fixed terminal a3 to one of the fifth selection terminal b5 and the sixth selection terminal b6 under the control of the control signal. Then, as Figure 8B shown, the communication link of the fourth RF module 34 includes the fourth RF module 34 passing through the fifth selection terminal b5 to the fourth antenna radiator ANT4, and the fourth RF module 34 passing through the sixth selection terminal b6 to the fifth antenna radiator ANT5.
[0178] For example, when the first RF module 31 emits a signal, the third selection switch 53 connects the third fixed terminal a3 to the sixth selection terminal b6 under the control of the control signal, and the fourth RF module 34 communicates via the fourth antenna radiator ANT4. When the first RF module 31 does not emit a signal, the third selection switch 53 connects the third fixed terminal a3 to the fifth selection terminal b5 under the control of the control signal, and the fourth RF module 34 communicates via the fifth antenna radiator ANT5.
[0179] In some embodiments, the TRP of the fourth RF module 34 is less than or equal to 15 dBm. For example, the operating frequency band of the fourth antenna radiator ANT4 may include a cellular network frequency band, a BT frequency band, a StarFlash frequency band, a WiFi frequency band, and a GPS frequency band.
[0180] In some embodiments, the second RF module 32 and the fourth RF module 34 are RF modules with different functions. For example, the second RF module 32 is a GPS communication module, and the fourth RF module 34 is a BT communication module.
[0181] Then, the electronic device 100 can achieve the coexistence of communication antennas with multiple functions and satellite communication antennas.
[0182] The electronic device 100 provided by the embodiment of the present application is configured such that the fourth radio frequency module 34 is matched with a switchable fourth antenna radiator ANT4 and a fifth antenna radiator ANT5. When the first radio frequency module 31 is not working, the fourth radio frequency module 34 is connected to the fourth antenna radiator ANT4. When the first radio frequency module 31 is working, the fourth radio frequency module 34 is connected to the fifth antenna radiator ANT5. The fifth antenna radiator ANT5 is located on the side of the fourth antenna radiator ANT4 away from the first antenna radiator ANT1. Therefore, the isolation between the fifth antenna radiator ANT5 and the first antenna radiator ANT1 is greater than the isolation between the fourth antenna radiator ANT4 and the first antenna radiator ANT1. Then, when the first radio frequency module 31 is working, the fourth radio frequency module 34 is connected to the fifth antenna radiator ANT5 with a greater isolation, which can reduce the energy of the transmission power of the first antenna radiator ANT1 coupled into the link where the fourth radio frequency module 34 is located, so as to reduce the risk of damage to the devices on the link where the fourth radio frequency module 34 is located, thereby achieving the purpose of coexistence of the first antenna radiator ANT1, the second antenna radiator ANT2, the third antenna radiator ANT3, the fourth antenna radiator ANT4, and the fifth antenna radiator ANT5 in the electronic device 100.
[0183] In some embodiments, the isolation between the fifth antenna radiator ANT5 and the first antenna radiator ANT1 is greater than or equal to 20 dB. For example, the isolation between the fifth antenna radiator ANT5 and the first antenna radiator ANT1 is 20 dB, 21 dB, 22 dB, 23 dB, 24 dB, 25 dB, 30 dB, 31 dB, 40 dB, etc.
[0184] Since the fourth radio frequency module 34 is connected to the fifth antenna radiator ANT5 when the first radio frequency module 31 transmits a signal. Then, by setting the isolation between the fifth antenna radiator ANT5 and the first antenna radiator ANT1 above 20 dB, it can meet the requirement that the energy of the transmission power of the first antenna radiator ANT1 coupled into the link where the fourth radio frequency module 34 is located is not sufficient to damage the devices on the link.
[0185] To meet the requirement of isolation, the length of the frame 10 from the seventh position 17 to the first position 11 can refer to the relevant descriptions in Tables 1 - 4 above, which will not be elaborated here.
[0186] In some embodiments, the second radio frequency module 32 and the fourth radio frequency module 34 can be integrated in the same module component. In other embodiments, the second radio frequency module 32 and the fourth radio frequency module 34 can also be two independent modules.
[0187] Figure 9A It is an architecture diagram of an electronic device provided by an embodiment of the present application. Figure 9BA topological schematic diagram of a radio frequency link provided by an embodiment of the present application.
[0188] In some embodiments, as Figure 9A shown, the electronic device 100 further includes a second selection switch 52 and a third radio frequency module 33.
[0189] The second selection switch 52 includes a second control end c2, a third selection end b3, a fourth selection end b4, and a second fixed end a2. The second selection end b2 is coupled to the third selection end b3, the fourth selection end b4 is coupled to the third radio frequency module 33, the second fixed end a2 is coupled to the third antenna radiator ANT3, and the second control end c2 is used to receive a control signal representing. Exemplarily, the second control end c2 is coupled to the first radio frequency module 31.
[0190] That is to say, whether the selection ends of the first selection switch 51 and the second selection switch 52 are switched is controlled by whether the first radio frequency module 31 is operating or not. Only when the operating state of the first radio frequency module 31 is switched, the first selection switch 51 and the second selection switch 52 will switch the selection ends. The second selection switch 52 is used to connect one of the third selection end b3 and the fourth selection end b4 to the second fixed end a2 under the control of the control signal. For example, the second selection switch 52 is specifically used to connect the second fixed end a2 to the fourth selection end b4 when the control signal represents that the first radio frequency module 31 does not transmit a signal. When the control signal represents that the first radio frequency module 31 transmits a signal, the second fixed end a2 is connected to the third selection end b3. Or it can be understood that the second selection switch 52 defaults to connect the second fixed end a2 to the fourth selection end b4, and when the first radio frequency module 31 transmits a signal, controls the second selection switch 52 to switch to connect the second fixed end a2 to the fourth selection end b4. When the first radio frequency module 31 does not transmit a signal, controls the second selection switch 52 to switch to the default state, and the second fixed end a2 is connected to the third selection end b3.
[0191] During the operation of the electronic device 100, the control signal represents that the first radio frequency module 31 transmits a signal. The first selection switch 51 controls the first fixed end a1 to be connected to the second selection end b2, and the second selection switch 52 controls the second fixed end a2 to be connected to the third selection end b3. Then, at this time, the radio frequency link of the electronic device 100 includes the first radio frequency module 31 - the first antenna radiator ANT1 and the second radio frequency module 32 - the third antenna radiator ANT3.
[0192] If the control signal indicates that the first RF module 31 does not transmit a signal, the first selection switch 51 controls the first fixed terminal a1 to be connected to the first selection terminal b1, and the second selection switch 52 controls the second fixed terminal a2 to be connected to the fourth selection terminal b4. Then, at this time, the RF link of the electronic device 100 includes the second RF module 32 - the second antenna radiator ANT2 and the third RF module 33 - the third antenna radiator ANT3.
[0193] The third antenna radiator ANT3 can be an antenna in the low frequency band or an antenna in the medium and high frequency bands. By way of example, the third RF module 33 can be a cellular communication module, a BT communication module, an NL communication module, a WiFi communication module, or a GPS communication module.
[0194] By setting the second selection switch 52, when the first RF module 31 is operating, the third antenna radiator ANT3 is used by the second RF module 32. When the first RF module 31 is not operating, the third antenna radiator ANT3 is used by the third RF module 33. The third antenna radiator ANT3 serves as the matching antenna radiator of the third RF module 33 and at the same time as the alternative antenna of the second antenna radiator ANT2. When the first RF module 31 is operating, the second RF module 32 can reuse the antenna radiator of the third RF module 33, and there is no need to separately provide an alternative antenna for the second antenna radiator ANT2, so as to reduce the requirement for the space adequacy of the electronic device 100.
[0195] In some embodiments, as Figure 9B shown, the first selection switch 51 is not integrated in the second RF module 32. In some embodiments, the second selection switch 52 is not integrated in the second RF module 32 or the third RF module 33.
[0196] Compared with integrating the selection switch in the RF module or other modules where the selection switch can only be controlled by the integrated module, setting the first selection switch 51 and / or the second selection switch 52 independently allows for flexible selection of the module that controls the selection switch.
[0197] The above-mentioned electronic device 100 provided by the embodiments of the present application aims to provide an alternative third antenna radiator ANT3 for the second RF module 32 on the basis that the second RF module 32 includes the conventional second antenna radiator ANT2. Further, the third antenna radiator ANT3 can be an antenna radiator shared with the third RF module 33 inside the electronic device 100.
[0198] The embodiments of the present application also provide an electronic device 100, aiming to provide an alternative first antenna radiator for the second RF module, and the second RF module and the first RF module share the same conventional antenna radiator.
[0199] Figure 10AIt is an architecture diagram of an electronic device provided by an embodiment of the present application. Figure 10B It is a topological schematic diagram of a radio frequency link provided by an embodiment of the present application.
[0200] An embodiment of the present application provides an electronic device 100. As Figure 10A shown, the electronic device 100 includes a rectangular frame 10, a first antenna radiator ANT1′, a second antenna radiator ANT2′, a first radio frequency module 31′, a second radio frequency module 32′, a first selection switch 51′, and a second selection switch 52′.
[0201] The frame 10 includes a first position 11′, a second position 12′, a third position 13′, and a fourth position 14′ arranged in sequence. The first position 11′ is located on the first side s1 of the frame 10, and the third position 13′ is located on the second side s2 of the frame 10. The first side s1 intersects the second side s2.
[0202] The first radio frequency module 31′ includes a radio frequency output end 31′, and the transmission power of the radio frequency output end 31′ is greater than or equal to 34 dBm. The first radio frequency module 31′ is, for example, a satellite communication module, and the second radio frequency module 32′ is, for example, a cellular communication module, a BT communication module, an NL communication module, a WiFi communication module, or a GPS communication module. The first radio frequency module 31′ and the second radio frequency module 32′ can refer to the relevant descriptions of the first radio frequency module 31 and the second radio frequency module 32 above.
[0203] The first antenna radiator ANT1′ includes a conductive part of the frame 10 between the first position 11′ and the second position 12′ and a first feeding end 21′. By way of example, the frame 10 has a slit at the second position 12′, a slit at the first position 11′, or a grounding end is provided ( Figure 10A in this example, the case where the frame 10 has a slit at the first position 11′ is used for illustration), and the first feeding end 21′ is arranged close to the second position 12′. The first antenna radiator ANT1′ can further refer to the relevant description of the first antenna radiator ANT1 above.
[0204] The second antenna radiator ANT2′ includes a conductive part of the frame 10 between the third position 13′ and the fourth position 14′ and a second feeding end 22′. By way of example, the frame 10 has a slit at the third position 13′, a slit at the fourth position 14′, or a grounding end is provided ( Figure 10A in this example, the case where the frame 10 has a grounding end at the fourth position 14′ is used for illustration), and the second feeding end 22′ is arranged close to the third position 13′. The second antenna radiator ANT2′ can further refer to the relevant description of the third antenna radiator ANT3 above.
[0205] In some embodiments, a power amplifier circuit may be provided between the second selection terminal b2' and the third selection terminal b3', and a power amplifier circuit may also be provided between the fourth selection terminal b4' and the second antenna radiator ANT2'.
[0206] As Figure 10B shown, the first selection switch 51' includes a first fixed terminal a1', a first control terminal c1', a first selection terminal b1' and a second selection terminal b2'. The second selection switch includes a second fixed terminal a2', a second control terminal c2', a third selection terminal b3' and a fourth selection terminal b4'. The first fixed terminal a1' is coupled to the first feeding terminal 21'. The first selection terminal b1' is coupled to the RF output terminal. The second selection terminal b2' is coupled to the third selection terminal b3'. The fourth selection terminal b4' is coupled to the second feeding terminal 22'. The second fixed terminal a2' is coupled to the second RF module 32'. The first control terminal c1' and the second control terminal c2' are used to receive a control signal indicating whether the first RF module 31' emits a signal.
[0207] Exemplarily, the first selection switch 51' is configured to connect the first fixed terminal a1' to one of the first selection terminal b1' and the second selection terminal b2' under the control of the control signal. The second selection switch 52' is configured to connect the second fixed terminal a2' to one of the third selection terminal b3' and the fourth selection terminal b4' under the control of the control signal.
[0208] For example, when the control signal indicates that the first RF module 31' emits a signal, the first selection switch 51 is configured to connect the first fixed terminal a1' to the first selection terminal b1' under the control of the control signal. The second selection switch 52' is configured to connect the second fixed terminal a2' to the fourth selection terminal b4' under the control of the control signal. At this time, the first RF module 31' transmits a signal through the first antenna radiator ANT1', and the second RF module 32' transmits a signal through the second antenna radiator ANT2'.
[0209] When the control signal indicates that the first RF module 31' does not emit a signal, the first selection switch 51 is configured to connect the first fixed terminal a1' to the second selection terminal b2' under the control of the control signal. The second selection switch 52' is configured to connect the second fixed terminal a2' to the third selection terminal b3' under the control of the control signal. At this time, the first RF module 31' does not transmit a signal, and the second RF module 32' transmits a signal through the first antenna radiator ANT1'.
[0210] The electronic device 100 provided by the embodiment of the present application is configured such that the second radio frequency module 32′ is matched with a switchable first antenna radiator ANT1′ and a second antenna radiator ANT2′. When the first radio frequency module 31′ is not working, the second radio frequency module 32′ is connected to the first antenna radiator ANT1′. When the first radio frequency module 31′ is working, the second radio frequency module 32′ is connected to the second antenna radiator ANT2′. The second antenna radiator ANT2′ and the first antenna radiator ANT1′ are not adjacent to each other. By adjusting the length of the frame 10 at the second position 12′ and the third position 13′, the isolation between the second antenna radiator ANT2′ and the first antenna radiator ANT1′ can be adjusted, so as to reduce the energy of the transmission power of the first antenna radiator ANT1′ coupled into the link where the second radio frequency module 32′ is located, thereby reducing the risk of damage to the devices on the link where the second radio frequency module 32′ is located, and achieving the purpose of coexistence of the second antenna radiator ANT2′ and the first antenna radiator ANT1′ in the electronic device 100. In addition, the first radio frequency module 31′ and the second radio frequency module 32′ share the first antenna radiator ANT1′, which can reduce the occupied area of the antenna radiator.
[0211] In some embodiments, the length of the frame 10 from the third position 13′ to the second position 12′ is greater than or equal to 10 mm. The setting of the length of the frame 10 from the third position 13′ to the second position 12′ can refer to the description of the length of the frame from the fourth position 14 to the second position 12 above, and will not be elaborated here.
[0212] In some embodiments, the isolation between the second antenna radiator ANT2′ and the first antenna radiator ANT1′ is greater than or equal to 20 dB, so as to meet the requirement that the energy of the transmission power of the first antenna radiator ANT1′ coupled into the link where the second radio frequency module 32′ is located is not sufficient to damage the devices on the link.
[0213] The isolation between the second antenna radiator ANT2′ and the first antenna radiator ANT1′ during operation can refer to the description of the isolation between the third antenna radiator ANT3 and the first antenna radiator ANT1 during operation above.
