[0031] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of the present application. The electronic device 1000 includes but is not limited to a mobile phone, a tablet computer, a laptop computer, a computer, a wearable device, a drone, a robot, a digital camera, and other devices with communication functions. The present embodiment of the application is described by taking a mobile phone as an example, and other electronic devices can refer to this embodiment.

[0032] See also Figure 2 , Figure 2 1 is a partial exploded schematic diagram of an electronic device 1000 provided in an embodiment of the present application. The electronic device includes a radio frequency system. The working environment of the radio frequency system 100 is illustrated by taking the electronic device 1000 as a mobile phone as an example. The electronic device 1000 includes a display screen 200, a middle frame 300 and a back cover 400 arranged in sequence along the thickness direction. Among them, the middle frame 300 includes a middle plate 310 and a frame 320 surrounding the side of the middle plate 310. The frame 320 is a conductive frame, such as a metal frame. A receiving space is formed between the display screen 200 and the middle plate 310, and between the middle plate 310 and the back cover 400 to accommodate the main circuit board 600, the camera module, the receiver module, the battery 700, the sub-board 800 and various sensors and other devices. One side of the frame 320 along the thickness direction is surrounded by the edge of the display screen 200, and the other side of the frame 320 along the thickness direction is surrounded by the edge of the back cover 400 to form a complete appearance structure of the electronic device 1000. In this embodiment, the frame 320 and the middle plate 310 are an integral structure, and the frame 320 and the back cover 400 are separate structures. The above is the working environment of the radio frequency system 100 taking a mobile phone as an example, but the radio frequency system 100 of the present application is not limited to the above working environment.

[0033] See also Figure 3 and Figure 4 The radio frequency system 100 includes a radio frequency transceiver module 10, a front-end module 20, a power division module 30 and at least one radiator 40.

[0034] Optionally, the radio frequency transceiver module 10 is a radio frequency transceiver.

[0035] The RF transceiver module 10 includes a transmitter and a receiver, wherein the transmitter is used to move the baseband modulated signal to the RF frequency through up-conversion, amplification, filtering and other processes, and transmit it through the antenna radiator 40; the receiver is used to receive the weak RF signal in the space through the antenna radiator 40, and then obtain the baseband signal through filtering, amplification, down-conversion and other processes, and finally send it to the demodulation module for demodulation.

[0036] See also Figure 3 and Figure 4 The front-end module 20 at least includes a first front-end transmitting module 21 and a second front-end transmitting module 22 .

[0037] One end of the first front-end transmitting module 21 is electrically connected to the RF transceiver module 10. The first front-end transmitting module 21 is used to transmit a RF signal supporting a first frequency band.

[0038] For details, please refer to Figure 4 The radio frequency transceiver module 10 includes a plurality of signal transceiver ports, wherein the plurality of signal transceiver ports include a first port 10a, and the first port 10a is used to transmit a radio frequency signal of a first frequency band.

[0039] The first frequency band includes but is not limited to LB band and HB band of communication standards such as 2G, LB band, MB band, HB band, UHB band of communication standards such as 3G, 4G, 5G or 6G, or Wi-Fi band.

[0040] One end of the first front-end transmitting module 21 is electrically connected to the first port 10a of the RF transceiver module 10, and the first front-end transmitting module 21 is used to receive a RF signal of a first frequency band from the RF transceiver module 10. The electrical connection method includes but is not limited to direct electrical connection or indirect electrical connection.

[0041] One end of the second front-end transmitting module 22 is electrically connected to the RF transceiver module 10. The second front-end transmitting module 22 is used to output a RF signal supporting the first frequency band.

[0042] See also Figure 4 , wherein the plurality of signal transceiver ports further include a second port 10b. The second port 10b is used to output a radio frequency signal of the first frequency band.

[0043] One end of the second front-end transmitting module 22 is electrically connected to the second port 10 b of the RF transceiver module 10 , and the second front-end transmitting module 22 is used to receive a RF signal of a first frequency band from the RF transceiver module 10 .

[0044] Optional, see Figure 4The first front-end transmitting module 21 includes a first power amplifier PA1. The frequency response range of the first power amplifier PA1 corresponds to the first frequency band. In other words, the first front-end transmitting module 21 is used to amplify the signal of the first frequency band.

[0045] See also Figure 4 The second front-end transmitting module 22 includes a second power amplifier PA2, and the frequency response range of the second power amplifier PA2 corresponds to the first frequency band. In other words, the second front-end transmitting module 22 is used to amplify the signal of the first frequency band.

[0046] For example, the first frequency band is the N41 frequency band. The first power amplifier PA1 is a power amplifier for amplifying the N41 frequency band. The second power amplifier PA2 is a power amplifier for amplifying the N41 frequency band.

[0047] For example, the first frequency band is the N78 frequency band. The first power amplifier PA1 is a power amplifier for amplifying the N78 frequency band. The second power amplifier PA2 is a power amplifier for amplifying the N78 frequency band.

[0048] In other embodiments, see Figure 4 The front-end module 20 further includes a first front-end receiving module 23, which includes a first low-loss amplifier (not shown) and a first receiving filter (not shown) electrically connected. The first receiving filter is used to pass the receiving frequency band of the first frequency band so as to receive the signal of the first frequency band.

[0049] Furthermore, the front-end module 20 also includes a first transceiver switching switch (not shown), which can switchably electrically connect the first front-end transmitting module 21 and the first front-end receiving module 23 to time-share the transmission and reception of the first frequency band.

[0050] The working mode of the signal transmission and reception of the first front-end receiving module 23 and the first front-end transmitting module 21 includes but is not limited to the time division duplex mode (TDD) or the frequency division duplex mode (FDD). When the working mode is the frequency division duplex mode (FDD), the first transmitting filter, the first receiving filter, and the first transmitting and receiving switch in the first front-end transmitting module 21 can be replaced by a duplexer.

[0051] The structure of the second front-end transmitting module 22 is similar to that of the first front-end transmitting module 21 .

[0052] See also Figure 4 The power division module 30 includes a first end 31 , a second end 32 and an output end 33 .

[0053] The first end 31 of the power division module 30 is electrically connected to the first input end of the first front-end transmitting module 21 .

[0054] The second end 32 of the power division module 30 is electrically connected to the second input end of the second front-end transmitting module 22 .

[0055] The radiator 40 is electrically connected to the output end 33 of the power division module 30 .

[0056] It can be understood that the power division module 30 includes but is not limited to a power divider. The power divider combines two signals of the same frequency band into one. Further optionally, the power division module 30 includes but is not limited to a unidirectional power divider. When the RF signal output by the first front-end transmitting module 21 flows into the power division module 30 through the first end 31, the RF signal output by the first front-end transmitting module 21 will flow out through the output end 33 of the power division module 30, and no or less RF signal will flow to the second end 32.

[0057] When the RF signal output by the second front-end transmitting module 22 flows into the power division module 30 via the second end 32 , the RF signal output by the second front-end transmitting module 22 flows out via the output end 33 of the power division module 30 , and no or less RF signal flows to the first end 31 .

[0058] In other words, the power division module 30 is used to superimpose the RF signal of the first frequency band of the first front-end transmitting module 21 with the RF signal of the first frequency band of the second front-end transmitting module 22 to form a RF signal of the first frequency band with increased power, and transmit the RF signal of the first frequency band to the radiator 40.

[0059] The radiator 40 has a first working state.

[0060] In the first working state, the radiator 40 is used to receive the RF signal of the first frequency band from the first front-end transmitting module 21 and the second front-end transmitting module 22 via the power division module 30, so that the transmission power of the radiator 40 when working in the first frequency band is increased. In other words, the first working state is a dual PA state.

[0061] As the environment of electronic devices becomes more and more complex, the environment of the radiator 40 of the electronic device becomes more and more complex. For example, when the electronic device is in a handheld state, the radiator 40 may be held by the hand and affect its transmission power; or, as more and more devices are installed inside the electronic device, the functions of the radio frequency system 100 increase and decrease, resulting in an increase or decrease in the number of devices on the radio frequency system 100, or the environment where the radio frequency system 100 is located affects the maximum transmission power of the radiator 40. Based on this, in the above case, the radiator 40 can be placed in the first working state, so that the transmission power of the radiator 40 can be increased, avoiding the problem of the maximum transmission power of the radiator 40 being reduced, or the problem of being unable to switch to this antenna, ensuring that the antenna can switch the radiator 40 to ensure the antenna coverage.

[0062] The electronic device 1000 provided in the present application includes a radio frequency system 100 , and the radio frequency system 100 includes a radio frequency transceiver module 10 , a front-end module 20 , a power division module 30 and at least one radiator 40 . The front-end module 20 includes a first front-end transmitting module 21 and a second front-end transmitting module 22, one end of the first front-end transmitting module 21 is electrically connected to the RF transceiver module 10, and the first front-end transmitting module 21 is used to transmit a RF signal supporting a first frequency band; one end of the second front-end transmitting module 22 is electrically connected to the RF transceiver module 10, and the second front-end transmitting module 22 is used to transmit a RF signal supporting the first frequency band; the first end 31 of the power division module 30 is electrically connected to the first input end of the first front-end transmitting module 21, and the second end 32 of the power division module 30 is electrically connected to the second input end of the second front-end transmitting module 22; the radiator 40 is electrically connected to the output end 33 of the power division module 30, and the radiator 40 has a first working state. In the first working state, the radiator 40 is used to receive RF signals from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30. In this way, the radiator 40 has a higher transmission power, avoiding the problem that the maximum transmission power of the radiator 40 is reduced, or the problem that it cannot be switched to this antenna, ensuring that the antenna can switch the radiator 40 to ensure the antenna coverage range.

[0063] Of course, in other embodiments, the RF transceiver module 10 provides a RF signal by controlling the first front-end transmitting module 21, and the second front-end transmitting module 22 does not provide a RF signal, and the first radiator 40 can receive the RF signal provided solely by the first front-end transmitting module 21. In other embodiments, the RF transceiver module 10 provides a RF signal by controlling the second front-end transmitting module 22, and the first front-end transmitting module 21 does not provide a RF signal, and the first radiator 40 can receive the RF signal provided solely by the second front-end transmitting module 22.

[0064] The specific structure of the radiator 40 provided in the embodiment is described below with reference to the accompanying drawings.

[0065] The present application does not specifically limit the material of the radiator 40. Optionally, the material of the radiator 40 is a conductive material, including but not limited to conductive materials such as metals and alloys. The present application does not specifically limit the form of the radiator 40. Optionally, the form of the radiator 40 includes but is not limited to a metal frame 320, a metal frame embedded in a plastic frame 320, a metal radiator 40 located in or on the surface of the frame 320, a flexible circuit board antenna formed on a flexible circuit board (Flexible Printed Circuitboard, FPC), a laser direct structured antenna by laser direct structure (Laser Direct Structuring, LDS), a printed direct structured antenna by printing direct structure (Print Direct Structuring, PDS), a conductive sheet antenna (such as a metal bracket antenna), etc. In this embodiment, the radiator 40 is taken as a part of the metal frame 320 of the electronic device 1000 as an example.

[0066] Optional, see Figure 5 , the at least one radiator 40 includes a first radiator 41.

[0067] See also Figure 5 , the first radiator 41 is electrically connected to the front-end module 20 via a first RF transmission line 51. The length of the first RF transmission line 51 affects the transmission loss between the first radiator 41 and the front-end module 20. When the length of the first RF transmission line 51 between the first radiator 41 and the front-end module 20 is long, or an extractor, a combiner, etc. are provided between the first radiator 41 and the front-end module 20, the loss between the first radiator 41 and the front-end module 20 will increase.

[0068] The insertion loss between the first radiator 41 and the front-end module 20 is greater than a preset insertion loss. The present application does not specifically limit the preset insertion loss. Optionally, the preset insertion loss causes the power at the first radiator 41 to be less than the power at the front-end module 20, and the power at the first radiator 41 is reduced to 0.3 times, 0.5 times, 0.6 times, 0.7 times, 0.8 times, 0.9 times, 0.95 times, etc., of the power at the front-end module 20.

[0069] From another perspective, the preset insertion loss may be a relatively large insertion loss. For example, there are multiple radiators 40 , and the insertion loss between the first radiator 41 and the front-end module 20 is larger than the insertion loss between the other radiators 40 and the front-end module 20 .

[0070] The first radiator 41 is in the first working state when it works in the first frequency band. That is, when the insertion loss between the first radiator 41 and the front-end module 20 is greater than the preset insertion loss, the first radiator 41 receives the RF signal of the first frequency band from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30. Compared with the RF signal sent by one front-end transmitting module received by the first radiator 41, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is larger. For example, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is increased to 1.5 to 2 times of the original (not limited to this data). In this way, even when the insertion loss between the first radiator 41 and the front-end module 20 is large, it can ensure that the first radiator 41 has sufficient transmission power in the first frequency band (for example, similar to the transmission power of other radiators 40 in the first frequency band), thereby ensuring that the RF system 100 can switch to the first radiator 41 when switching to a different radiator 40. In this way, the RF system 100 can send and receive signals within the range covered by the first radiator 41.

[0071] For example, see Figure 6 , at least one radiator 40 includes a first radiator 41 and a third radiator 43, the first radiator 41 is arranged on the bottom frame 324, the third radiator 43 is arranged on the top frame 321, and the length of the first RF transmission line 51 between the first radiator 41 and the front-end module 20 is much greater than the length of the third RF transmission line 53 between the third radiator 43 and the front-end module 20. When the first radiator 41 is electrically connected to a front-end transmitting module, the transmission power (for example, 0.6P) of the first radiator 41 transmitting the first frequency band is less than the transmission power (for example, 1P) of the second radiator 40 transmitting the first frequency band when the second radiator 40 is electrically connected to a front-end transmitting module. Since the transmission power of the first radiator 41 transmitting the first frequency band is low when the first radiator 41 is electrically connected to a front-end transmitting module, the antenna switch of the RF system 100 will not choose to switch to the first radiator 41 when switching the radiator 40 to detect a better channel, resulting in the first radiator 41 The coverage range cannot achieve the first frequency band transmission and reception, reducing the coverage range of the uplink signal.

[0072] In this embodiment, the first radiator 41 receives the RF signal of the first frequency band from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30. When the first radiator 41 is electrically connected to the two front-end transmitting modules, the transmission power of the first frequency band transmitted by the first radiator 41 (for example, 1.2P) is similar to the transmission power of the first frequency band transmitted by the second radiator 40 (for example, 1P) when the second radiator 40 is electrically connected to one front-end transmitting module, and meets the transmission power requirement of the first frequency band. Therefore, when the antenna switch of the RF system 100 switches the radiator 40 to detect a better channel, it will choose to switch to the first radiator 41, so that the coverage range of the first radiator 41 can realize the reception and transmission of the first frequency band, thereby ensuring the coverage range of the uplink signal.

[0073] As mentioned above, see Figure 3 , Figure 5 and Figure 6 The electronic device 1000 further includes a frame 320 and a main circuit board 600. The frame 320 includes a top frame 321, a first side frame 322, a bottom frame 324 and a second side frame 323 which are connected in sequence.

[0074] See also Figure 3 , Figure 3 1 is a partial back schematic diagram of the electronic device 1000 provided in an embodiment of the present application without the back cover 400. The frame 320 includes a top frame 321 and a bottom frame 324 arranged relatively to each other, and a first side frame 322 and a second side frame 323 connected to the top frame 321 and the bottom frame 324. Among them, the top frame 321 is the side away from the ground when the user holds the electronic device 1000 and uses the screen vertically, and the bottom frame 324 is the side facing the ground when the user holds the electronic device 1000 and uses the screen vertically. The first side frame 322 is the left side when the user holds the electronic device 1000 and uses the screen vertically. The second side frame 323 is the right side when the user holds the electronic device 1000 and uses the screen vertically. Of course, the first side frame 322 can also be the right side when the user holds the electronic device 1000. The second side frame 323 is the left side when the user holds the electronic device 1000.

[0075] Optionally, the top frame 321 is a straight frame, the first side frame 322 and the second side frame 323 are both straight frames in the middle, and the two ends are bent frames, wherein the bending angles of the bent frames at the two ends of the first side frame 322 are close to or 90°. The bending angles of the bent frames at the two ends of the second side frame 323 are close to or 90°. The bent frames are curved in an arc. The bottom frame 324 is a straight frame.

[0076] See also Figure 3 , Figure 5 and Figure 6, the main circuit board 600 is located on a side close to the top frame 321. Specifically, the main circuit board 600 is located in a space surrounded by the portion (upper half) of the first side frame 322 close to the top frame 321, the top frame 321, and the portion (upper half) of the second side frame 323 close to the top frame 321.

[0077] See also Figure 3 , Figure 5 and Figure 6 , the RF transceiver module 10 and the front-end module 20 are both arranged on the main circuit board 600. Specifically, the RF transceiver module 10 can exist in the form of a chip. The front-end module 20 can exist in the form of a chip. Of course, the RF transceiver module 10 and the front-end module 20 can be integrated in the same chip.

[0078] Generally, the main circuit board 600 , the battery 700 , and the sub-board 800 are sequentially arranged from the top frame 321 to the bottom frame 324 .

[0079] In a first alternative implementation, see Figure 5 When the front-end module 20 is arranged on the main circuit board 600 and the first radiator 41 is located at the bottom frame 324, the first RF transmission line 51 between the first radiator 41 and the front-end module 20 needs to cross the battery 700, the sub-board 800, etc. The length of the first RF transmission line 51 is relatively long, and the insertion loss between the first radiator 41 and the front-end module 20 is relatively large. In the embodiment of the present application, it can be considered that the insertion loss between the first radiator 41 and the front-end module 20 is greater than the preset insertion loss.

[0080] In this implementation, see Figure 4 When the RF system 100 transmits and receives the first frequency band through the first radiator 41, the first radiator 41 can be placed in the first working state. The first radiator 41 receives the RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30. Compared with the first radiator 41 receiving the RF signal sent by one front-end transmitting module, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is larger. For example, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is increased to 1.5 to 2 times of the original (not limited to this data). In this way, even when the insertion loss between the first radiator 41 and the front-end module 20 is large, it can be ensured that the first radiator 41 has sufficient transmission power in the first frequency band (for example, similar to the transmission power of other radiators 40 in the first frequency band), thereby ensuring that the RF system 100 can switch to the first radiator 41 when switching to a different radiator 40. In this way, the RF system 100 can transmit and receive signals within the range covered by the first radiator 41.

[0081] In a second alternative implementation, see Figure 7 The first radiator 41 is located at a position of the first side frame 322 close to the bottom frame 324 .

[0082] Specifically, the first radiator 41 is located on the first side frame 322 , and the first radiator 41 is located between the bottom edge of the battery 700 and the bottom frame 324 .

[0083] When the front-end module 20 is arranged on the main circuit board 600, the first radiator 41 is located on the first side frame 322 and the first radiator 41 is located between the bottom edge of the battery 700 and the bottom frame 324, the first RF transmission line 51 between the first radiator 41 and the front-end module 20 needs to cross the battery 700, the sub-board 800, etc. The length of the first RF transmission line 51 is relatively long, and the insertion loss between the first radiator 41 and the front-end module 20 is relatively large. In the embodiment of the present application, it can be considered that the insertion loss between the first radiator 41 and the front-end module 20 is greater than the preset insertion loss.

[0084] In this embodiment, when the RF system 100 transmits and receives the first frequency band through the first radiator 41, the first radiator 41 can be placed in the first working state. The first radiator 41 receives the RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22 via the power division module 30. Compared with the first radiator 41 receiving the RF signal sent by one front-end transmitting module, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is larger. For example, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is increased to 1.5 to 2 times of the original (not limited to this data). In this way, even when the insertion loss between the first radiator 41 and the front-end module 20 is large, it can be ensured that the first radiator 41 has sufficient transmission power in the first frequency band (for example, similar to the transmission power of other radiators 40 in the first frequency band), thereby ensuring that the RF system 100 can switch to the first radiator 41 when switching to a different radiator 40. In this way, the RF system 100 can transmit and receive signals within the range covered by the first radiator 41.

[0085] In a third alternative implementation, see Figure 8 , the first radiator 41 is located at a position of the second side frame 323 close to the bottom frame 324. Specifically, the first radiator 41 is located on the second side frame 323, and the second radiator 40 is located between the bottom edge of the battery 700 and the bottom frame 324.

[0086] When the front-end module 20 is arranged on the main circuit board 600, the first radiator 41 is located on the second side frame 323, and the second radiator 40 is located between the bottom edge of the battery 700 and the bottom frame 324, the first RF transmission line 51 between the first radiator 41 and the front-end module 20 needs to cross the battery 700, the sub-board 800, etc. The length of the first RF transmission line 51 is relatively long, and the insertion loss between the first radiator 41 and the front-end module 20 is relatively large. In the embodiment of the present application, it can be considered that the insertion loss between the first radiator 41 and the front-end module 20 is greater than the preset insertion loss.

[0087] In this embodiment, when the RF system 100 transmits and receives the first frequency band through the first radiator 41, the first radiator 41 can be placed in the first working state. The first radiator 41 receives the RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22 via the power division module 30. Compared with the first radiator 41 receiving the RF signal sent by one front-end transmitting module, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is larger. For example, the transmission power of the first frequency band received by the first radiator 41 in this embodiment is increased to 1.5 to 2 times of the original (not limited to this data). In this way, even when the insertion loss between the first radiator 41 and the front-end module 20 is large, it can be ensured that the first radiator 41 has sufficient transmission power in the first frequency band (for example, similar to the transmission power of other radiators 40 in the first frequency band), thereby ensuring that the RF system 100 can switch to the first radiator 41 when switching to a different radiator 40. In this way, the RF system 100 can transmit and receive signals within the range covered by the first radiator 41.

[0088] Optional, see Fig. 9 , the at least one radiator 40 further includes a second radiator 42. The first radiator 41 is disposed on the bottom frame 324. The second radiator 42 is disposed on the first side frame 322 near the bottom frame 324. Of course, in other embodiments, the second radiator 42 may also be disposed on the second side frame 323 near the bottom frame 324.

[0089] See also Fig. 9 The RF system 100 further includes a first switch 61. A fixed end of the first switch 61 is electrically connected to the output end 33 of the power division module 30. A first selection end 61b of the first switch 61 is electrically connected to the first radiator 41. A second selection end 61c of the first switch 61 is electrically connected to the second radiator 42.

[0090] The electronic device 1000 further includes a controller (not shown), which is electrically connected to the first switch 61 .

[0091] See also Fig. 9When the controller switches to the first switch 61 so that the fixed end 61a and the first selection end 61b are turned on, the first radiator 41 receives the RF signal of the first frequency band from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30. In other words, the first radiator 41 receives the RF signal from the dual PA.

[0092] When the controller switches the fixed end 61a of the first switch 61 to the second selection end 61c, the second radiator 42 receives the RF signal of the first frequency band from the first front-end transmitting module 21 and the second front-end transmitting module 22 via the power division module 30. In other words, the second radiator 42 receives the RF signal from the dual PA.

[0093] As mentioned above, see Fig.10 Since the first RF transmission line 51 between the first radiator 41 and the front-end module 20 and the second RF transmission line 52 between the second radiator 42 and the front-end module 20 are both longer, the insertion loss between the first radiator 41, the second radiator 42 and the front-end module 20 is greater than the preset insertion loss.

[0094] In the present embodiment, on the one hand, the transmission power of the first radiator 41 and the second radiator 42 can be improved to compensate for the problem of large insertion loss caused by the long first RF transmission line 51 and the second RF transmission line 52; on the other hand, the first radiator 41 and the second radiator 42 are arranged on different sides of the frame 320 to form different radiation patterns. Therefore, by controlling the first switch 61, the first radiator 41 or the second radiator 42 can be switched to operate in the first frequency band to support a larger coverage range when operating in the first frequency band, thereby improving the performance of the first frequency band, etc.

[0095] As mentioned above, the first radiator 41 can receive the RF signal provided by the first front-end transmitting module 21 alone, or receive the RF signal provided by the second front-end transmitting module 22 alone, and simultaneously receive the RF signal provided by the first front-end transmitting module 21 and the second front-end transmitting module 22. Correspondingly, the second radiator 42 can receive the RF signal provided by the first front-end transmitting module 21 alone, or receive the RF signal provided by the second front-end transmitting module 22 alone, and simultaneously receive the RF signal provided by the first front-end transmitting module 21 and the second front-end transmitting module 22.

[0096] See also Fig.11When the RF system 100 further includes a third radiator 43 and a fourth radiator 44, the third radiator 43 and the fourth radiator 44 can be disposed near the main circuit board 600, and the insertion loss between the third radiator 43 and the fourth radiator 44 and the front-end module 20 can be less than the preset insertion loss. When the antenna switch of the RF system 100 is switched to the third radiator 43 (or the fourth radiator 44), the third radiator 43 (or the fourth radiator 44) can be electrically connected to a front-end transmitting module, thereby saving power consumption while ensuring that the transmission power of the third radiator 43 (or the fourth radiator 44) is sufficient.

[0097] Optionally, the radiator 40 also has a second working state. In the second working state, the radiator 40 receives the RF signal from the first front-end transmitting module 21. In other words, the second working state is a single PA state. Of course, in other embodiments, in the second working state, the radiator 40 can also receive the RF signal from the second front-end transmitting module 22.

[0098] See also Fig.12 The RF system 100 further includes a first switch unit 71. A fixed end 71a of the first switch unit 71 is electrically connected to the first front-end transmitting module 21. A second selection end 71c of the first switch unit 71 is electrically connected to the radiator 40 ( Fig.12 The first selection end 71 b of the first switch unit 71 is electrically connected to the first end 31 of the power division module 30 .

[0099] The electronic device 1000 further includes a controller, which is electrically connected to the first switch unit 71. The controller is used to control the fixed end 71a of the first switch unit 71 to be connected to the first selection end 71b or the second selection end 71c.

[0100] When the fixed end 71 a of the first switch unit 71 is connected to the second selection end 71 c , the radiator 40 operates in the first operating state. At this time, the radiator 40 receives a radio frequency signal from a front-end transmitting module.

[0101] When the fixed end 71 a of the first switch unit 71 is connected to the first selection end 71 b , the radiator 40 operates in the second operating state. At this time, the radiator 40 receives radio frequency signals from two front-end transmitting modules.

[0102] In this embodiment, a radiator 40 can be switched to a first working state (dual PA state) or a second working state (single PA state) through a first switch unit 71. The insertion loss between the radiator 40 and the front-end module 20 can be greater than a preset insertion loss or less than a preset insertion loss. In other words, the radiator 40 is close to the main circuit board 600, or is far away from the main circuit board 600. When the radiator 40 (such as the subsequent third radiator 43) is located near the main circuit board 600, the radiator 40 can have a single PA state and a dual PA state; under conventional communication, the radiator 40 can be in a single PA state, and the radiator 40 has sufficient transmission power and saves power consumption; in weak field conditions such as basements or places with dense traffic, the radiator 40 can be switched to a dual PA state, so that the radiator 40 has a stronger transmission power to ensure that the electronic device 1000 has a stronger signal connection and improve the user experience.

[0103] Optionally, the radiator 40 also has a third working state. In the third working state, the radiator 40 receives a radio frequency signal from the first front-end transmitting module 21 or the second front-end transmitting module 22. The third working state in this embodiment can refer to the description of the second working state mentioned above. The third working state and the second working state are both single PA states.

[0104] See also Fig.13 The RF system 100 also includes a first switch unit 71 and a second switch unit 72.

[0105] The electronic device 1000 further includes a controller, which is electrically connected to the first switch unit 71. The controller is used to control the fixed end 71a of the first switch unit 71 to be turned on or off with the first selection end 71b. The controller is electrically connected to the second switch unit 72. The controller is used to control the fixed end 72a of the second switch unit 72 to be turned on or off with the first selection end 72b.

[0106] The fixed end 71a of the first switch unit 71 is electrically connected to the first front-end transmitting module 21. The selection end of the first switch unit 71 is electrically connected to the first end 31 of the power division module 30.

[0107] The fixed end 72a of the second switch unit 72 is electrically connected to the second front-end transmitting module 22. The selection end of the second switch unit 72 is electrically connected to the second end 32 of the power division module 30.

[0108] When the fixed end 71a of the first switch unit 71 is connected to the selection end and the fixed end 72a of the second switch unit 72 is connected to the selection end, the radiator 40 operates in the first working state (dual PA state), and the radiator 40 receives RF signals from two front-end transmitting modules.

[0109] When the fixed end 71a of the first switch unit 71 is connected to the selection end and the fixed end 72a of the second switch unit 72 is disconnected from the selection end, the radiator 40 operates in the third working state (single PA state) and receives the RF signal from the first front-end transmitting module 21.

[0110] When the fixed end 71a of the first switch unit 71 is disconnected from the selection end and the fixed end 72a of the second switch unit 72 is connected to the selection end, the radiator 40 operates in the third working state (single PA state) and receives the RF signal from the second front-end transmitting module 22.

[0111] In this embodiment, a radiator 40 can be switched to a first working state (dual PA state) or a second working state (single PA state) through a first switch unit 71 and a second switch unit 72. The insertion loss between the radiator 40 and the front-end module 20 can be greater than a preset insertion loss or less than a preset insertion loss. In addition, when the radiator 40 is working in a single PA state, the radiator 40 can also be flexibly and selectively switched to different front-end transmitting modules.

The second selection end 62c of the second switch 62 and the second selection end 72c of the second switch unit 72 are electrically connected to the third radiator 43.

[0114] The electronic device 1000 further includes a controller, which is electrically connected to the second switch 62. The controller is used to control the fixed end 62a of the second switch 62 to be connected to the first selection end 62b or the second selection end 62c.

[0115] When the fixed end 71 a and the second selection end 71 c of the first switch unit 71 are connected, the first radiator 41 receives the single PA radio frequency signal from the first front-end transmitting module 21 .

[0116] When the fixed end 71a of the first switch unit 71 is turned on and the second selection end 71c is turned on, the fixed end 72a of the second switch unit 72 is turned on and the first selection end 72b, and the fixed end 62a of the second switch 62 is turned on and the first selection end 62b, the first radiator 41 receives the dual PA RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22.

[0117] When the fixed end 71a of the first switch unit 71 is turned on and the first selection end 71b, the fixed end 72a of the second switch unit 72 is turned on and the second selection end 72c, and the fixed end 62a of the second switch 62 is turned on and the second selection end 62c, the third radiator 43 receives the dual PA RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22.

[0118] When the fixed terminal 72 a and the second selection terminal 72 c of the second switch unit 72 are connected, the third radiator 43 receives the single PA radio frequency signal from the second front-end transmitting module 22 .

[0119] In this embodiment, the first radiator 41 and the third radiator 43 can be switched to the first working state (dual PA state) or the second working state (single PA state) through the first switch unit 71, the second switch unit 72 and the second switch 62. In this way, the first radiator 41 has a single PA state and a dual PA state, and the third radiator 43 has a single PA state and a dual PA state.

[0133] When the fixed end 72 a of the second switch unit 72 is connected to the second selection end 72 c and the fixed end 63 a of the third switch 63 is connected to the second selection end 63 c , the fourth radiator 44 receives the single PA RF signal from the second front-end transmitting module 22 .

[0134] In this embodiment, the first radiator 41, the second radiator 42, the third radiator 43, and the fourth radiator 44 can be switched to the first working state (dual PA state) or the second working state (single PA state) through the first switch unit 71, the second switch unit 72, the first switch 61, the second switch 62, and the third switch 63. In this way, the first radiator 41 has a single PA state and a dual PA state, the second radiator 42 has a single PA state and a dual PA state, the third radiator 43 has a single PA state and a dual PA state, and the fourth radiator 44 has a single PA state and a dual PA state. The insertion loss between the first radiator 41 and the front-end module 20 can be greater than the preset insertion loss or less than the preset insertion loss. The insertion loss between the second radiator 42 and the front-end module 20 can be greater than the preset insertion loss or less than the preset insertion loss. The insertion loss between the third radiator 43 and the front-end module 20 can be greater than the preset insertion loss or less than the preset insertion loss. The insertion loss between the fourth radiator 44 and the front-end module 20 can be greater than the preset insertion loss or less than the preset insertion loss.

[0135] In this embodiment, the first front-end transmitting module 21, the first front-end receiving module 23, the first radiator 41 and the second radiator 42 form a 1T2R (one-way transmitting and two-way receiving) antenna. During transmission, the single PA state of the first front-end transmitting module 21 or the dual PA state of the first front-end transmitting module 21 and the second front-end transmitting module 22 can be selected.

[0136] Furthermore, the second front-end transmitting module 22, the second front-end receiving module 24, the third radiator 43 and the fourth radiator 44 form a 1T2R (one transmission and two reception) antenna. During transmission, the single PA state of the second front-end transmitting module 22 alone or the dual PA state of the first front-end transmitting module 21 and the second front-end transmitting module 22 can be selected.

[0137] In other words, two 1T2R antenna groups can be formed above.

[0138] In this embodiment, the first front-end transmitting module 21, the first front-end receiving module 23, the first radiator 41, the second radiator 42, the third radiator 43, and the fourth radiator 44 can form a 1T4R (one-way transmitting and four-way receiving) antenna. During transmission, the single PA state of the first front-end transmitting module 21 or the dual PA state of the first front-end transmitting module 21 and the second front-end transmitting module 22 can be selected.

[0139] Furthermore, the second front-end transmitting module 22, the second front-end receiving module 24, the first radiator 41, the second radiator 42, the third radiator 43, and the fourth radiator 44 can form a 1T4R (one-way transmitting and four-way receiving) antenna. During transmission, the single PA state of the second front-end transmitting module 22 alone or the dual PA state of the first front-end transmitting module 21 and the second front-end transmitting module 22 can be selected.

[0140] In other words, two 1T4R antenna groups can be formed above.

[0141] In this embodiment, the first front-end transmitting module 21, the first front-end receiving module 23, the second front-end transmitting module 22, the second front-end receiving module 24, the first radiator 41, the second radiator 42, the third radiator 43, and the fourth radiator 44 can form a 2T4R (one-way transmitting and four-way receiving) antenna. During transmission, the first front-end transmitting module 21 and the second front-end transmitting module 22 support a dual PA state.

[0142] Optionally, in a MIMO antenna system, the transmit power balance between MIMO antennas affects the performance of the MIMO antenna system. Based on this, when the first radiator 41 and other radiators 40 form a 2*2 MIMO antenna system, the transmit power of the first radiator 41 in the first frequency band is larger than the transmit power of other radiators 40 in the first frequency band, which may result in poor performance of the MIMO antenna system. Alternatively, when the first radiator 41, the second radiator 42, the third radiator 43 and the fourth radiator 44 form a 4*4 MIMO antenna system, the transmit power of the first radiator 41 in the first frequency band is larger than the transmit power of other radiators 40 in the first frequency band, which may result in poor performance of the MIMO antenna system.

[0143] Based on this, see Fig.16 , the RF system 100 also includes a third front-end transmitting module 25. When the insertion loss of the first radiator 41 is greater than the preset insertion loss, the insertion losses of the second radiator 42, the third radiator 43 and the fourth radiator 44 are all less than the preset insertion loss, and the first radiator 41, the second radiator 42, the third radiator 43 and the fourth radiator 44 are to realize dual-channel simultaneous transmission, the first radiator 41 can be switched to be electrically connected to the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30 to receive the dual-PA RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22, and any one of the second radiator 42, the third radiator 43 and the fourth radiator 44 can be switched to be electrically connected to the third front-end transmitting module 25 to receive the single-PA RF signal. In this way, the transmission power of the first radiator 41 in the dual-PA state is similar to the transmission power of other radiators 40 (any one of the second radiator 42, the third radiator 43 and the fourth radiator 44) in the single-PA state to form 2*2MIMO.

[0144] See also Fig.11 When the transmission power of the first radiator 41 and the second radiator 42 in the first frequency band is larger than the transmission power of other radiators 40 (the third radiator 43 and the fourth radiator 44) in the first frequency band, the performance of the MIMO antenna system may be poor.

[0145] Based on this, see Fig.17 The radio frequency system 100 further includes a fourth switch 64 and a power distribution unit 80. The fourth switch 64 is connected in parallel with the power distribution unit 80 and is electrically connected between the second front-end transmitting module 22 and the second switch unit 72. When the fourth switch 64 is turned on, the following is formed: Fig.15RF frame structure. When the fourth switch 64 is disconnected, the power distribution unit 80 is electrically connected between the second front-end transmitting module 22 and the second switch unit 72. The power distribution unit 80 can divide the output power of the second front-end transmitting module 22 into multiple parts, each of which can be the same or different, and transmit a part of the output power to the second switch unit 72, and another part of the output power to the first switch unit 71. For example, the power distribution unit 80 divides the output power P1 of the second front-end transmitting module 22 into a first sub-output power 1 / 3P1 and a second sub-output power 2 / 3P1, and transmits the first sub-output power 1 / 3P1 to the first switch unit 71. If the output power of the second front-end transmitting module 22 is also P1, the power when the first radiator 41 and the second radiator 42 work at the same time is 2 / 3P1. The power distribution unit 80 transmits the second sub-output power 2 / 3P1 to the third radiator 43 and the fourth radiator 44 respectively, and the power when the third radiator 43 and the fourth radiator 44 work at the same time is 1 / 3P1.

[0146] Since the insertion losses of the first radiator 41 and the second radiator 42 are both greater than the preset insertion losses, the insertion losses of the third radiator 43 and the fourth radiator 44 are both less than the preset insertion losses, and when the first radiator 41, the second radiator 42, the third radiator 43 and the fourth radiator 44 want to realize four-channel simultaneous transmission, the first radiator 41 and the second radiator 42 can have relatively large power to compensate for the power loss caused by the large insertion loss, so that the transmission power of the first radiator 41, the second radiator 42, the third radiator 43 and the fourth radiator 44 are similar to form 4*4 MIMO.

[0147] As mentioned above, the electronic device 1000 further includes a frame 320 and a controller. The at least one radiator 40 is disposed on the frame 320 .

[0148] The at least one radiator 40 includes a first radiator 41. The first radiator 41 is located in a horizontal screen holding area of ​​the electronic device 1000. The controller is used to control the first radiator 41 to be in the first working state according to the electronic device 1000 being in the horizontal screen holding state.

[0149] The horizontal screen holding area of ​​the electronic device 1000 includes but is not limited to the area where the top frame 321 and the bottom frame 324 of the electronic device 1000 are located.

[0150] In this embodiment, the first radiator 41 is disposed in the region where the top frame 321 of the electronic device 1000 is located or in the region where the bottom frame 324 is located. For example, the first radiator 41 is disposed in the region where the bottom frame 324 is located.

[0151] When the electronic device 1000 is in a horizontal screen holding state, the first radiator 41 is blocked or held by the hand, which may cause the maximum transmission power of the first radiator 41 to be reduced, and the signal strength of the first radiator 41 receiving and transmitting the first frequency band is poor, which in turn causes the antenna switch of the RF system 100 to not switch to the first radiator 41 when switching. In this way, the radiation range of the RF system 100 in the first frequency band will not cover the radiation area of ​​the first radiator 41.

[0152] Based on this, the controller is used to control the first radiator 41 to be in the first working state according to the electronic device 1000 being in the horizontal screen holding state. In other words, the controller is used to control the radiator 40 (first radiator 41) blocked by the hand or held by the hand to receive the RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30 according to the electronic device 1000 being in the horizontal screen holding state, that is, the radiator 40 (first radiator 41) blocked by the hand or held by the hand is in the dual PA state to compensate for the reduction in transmission power caused by the first radiator 41 being blocked or held by the hand, so that the transmission power of the first radiator 41 in the dual PA state is sufficient, and the antenna switch of the RF system 100 will also switch to the first radiator 41 when switching, so that the radiation range of the RF system 100 in the first frequency band will be able to cover the radiation area of ​​the first radiator 41, ensuring the coverage range of the transmitted uplink signal.

[0153] Optionally, a method of determining that the electronic device 1000 is in the horizontal screen holding state includes but is not limited to: comparing the posture of the electronic device 1000 and the emission power values ​​of the first radiator 41 before and after.

[0154] The electronic device 1000 further includes a sensor, and the sensor is used to detect whether the posture of the electronic device 1000 is a horizontal screen posture.

[0155] The controller monitors the transmission power of the first radiator 41 at a certain frequency, and the difference between the transmission power of the first radiator 41 and the transmission power in the previous t time period is greater than or equal to a preset value, and the controller determines that the electronic device 1000 is in a horizontal screen holding posture according to the transmission power of other radiators 40 located outside the horizontal screen holding area and working in the first frequency band has not decreased or has decreased very little. For example, the electronic device 1000 detects through a sensor that the posture of the electronic device 1000 is a horizontal screen posture. The controller also monitors that the current transmission power of the first radiator 41 is 0.7 times (not limited to this data) of the transmission power in the previous t time period, and the controller determines that the first radiator 41 located in the horizontal screen holding area is blocked or held by the hand according to the transmission power of other radiators 40 located outside the horizontal screen holding area and working in the first frequency band has not decreased or has decreased very little. At this time, the posture of the electronic device 1000 is in a horizontal screen holding posture.

[0156] Optionally, the at least one radiator 40 further includes a second radiator 42. The second radiator 42 is located outside the horizontal screen holding area of ​​the electronic device 1000. For example, the second radiator 42 is located on the first side frame 322 or the second side frame 323. When the electronic device 1000 is in the horizontal screen holding state, the second radiator 42 is not blocked or held by the hand.

[0157] The controller is used to control the first radiator 41 to work in the first frequency band and be in the first working state according to a first condition, wherein the first condition includes that the main radiation direction of the directional pattern of the first radiator 41 when working in the first frequency band is a first preset direction.

[0158] The controller is used to control the second radiator 42 to work in the first frequency band and be in the first working state or the second working state according to a second condition. The second working state is that the second radiator 42 receives a radio frequency signal from the first front-end transmitting module 21 or the second front-end transmitting module 22. The second condition includes the main radiation direction of the first radiator 41 and the signal strength of the second radiator 42 working in the first frequency band and being in the first working state or the second working state.

[0159] Specifically, when the electronic device 1000 is in the horizontal screen holding state, it has several working modes.

[0160] For example, the first working mode is that the controller sets the main radiation direction of the radiation pattern of the first radiator 41 working in the first frequency band as the first preset direction. For example, the main radiation direction of the radiation pattern of the first radiator 41 in the first frequency band is toward the base station. At this time, the controller can control the first radiator 41 to receive the RF signals from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30, and be in a dual PA state to ensure that the first frequency band has a higher radiation power in the first preset direction.

[0161] For example, the second working mode is that the controller controls the main radiation direction of the directional pattern of the first radiator 41 working in the first frequency band to be not the first preset direction, for example, the main radiation direction of the directional pattern of the first radiator 41 in the first frequency band is not toward the base station, and the signal strength of the second radiator 42 working in the first frequency band and in the first working state or the second working state is greater than the signal strength of the first radiator 41 working in the first frequency band and in the second working state. At this time, the controller can control the second radiator 42 to be in the first working state (single PA state) or the second working state (dual PA state) to ensure that the first frequency band has a higher radiation power.

[0162] Optionally, the electronic device 1000 further includes a frame 320 and a controller. The at least one radiator 40 is disposed on the frame 320 .

[0163] The at least one radiator 40 includes a second radiator 42. The second radiator 42 is located in the vertical screen holding area of ​​the electronic device 1000. The controller is used to control the second radiator 42 to be in the first working state according to the electronic device 1000 being in the vertical screen holding state.

[0164] The vertical screen holding area of ​​the electronic device 1000 includes but is not limited to an area where the first side frame 322 and the second side frame 323 of the electronic device 1000 are located.

[0165] In this embodiment, the second radiator 42 is disposed in the area where the first side frame 322 of the electronic device 1000 is located or in the area where the second side frame 323 is located. For example, the second radiator 42 is disposed in the middle and lower part of the second side frame 323 .

[0166] When the electronic device 1000 is in a portrait-screen holding state, the second radiator 42 is blocked or held by the hand, which may cause the maximum transmission power of the second radiator 42 to be reduced, and the signal strength of the second radiator 42 receiving and transmitting the first frequency band is poor, which in turn causes the antenna switch of the RF system 100 to not switch to the second radiator 42 when switching. In this way, the radiation range of the RF system 100 in the first frequency band will not cover the radiation area of ​​the second radiator 42.

[0167] Based on this, the controller is used to control the second radiator 42 to be in the first working state according to the electronic device 1000 being in the vertical screen holding state. In other words, the controller is used to control the radiator 40 (second radiator 42) blocked by the hand or held by the hand to receive the RF signal from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30 according to the electronic device 1000 being in the vertical screen holding state, that is, the radiator 40 (second radiator 42) blocked by the hand or held by the hand is in the dual PA state to compensate for the reduction in transmission power caused by the second radiator 42 being blocked or held by the hand, so that the transmission power of the second radiator 42 in the dual PA state is sufficient, and the antenna switch of the RF system 100 will also switch to the second radiator 42 when switching, so that the radiation range of the RF system 100 in the first frequency band will be able to cover the radiation area of ​​the second radiator 42, ensuring the coverage range of the transmitted uplink signal.

[0168] Optionally, a method of determining that the electronic device 1000 is in the portrait holding state includes, but is not limited to, comparing the posture of the electronic device 1000 and the emission power values ​​of the second radiator 42 before and after.

[0169] The electronic device 1000 further includes a sensor, and the sensor is used to detect whether the posture of the electronic device 1000 is a vertical screen posture.

[0170] The controller monitors the transmission power of the second radiator 42 at a certain frequency, and the difference between the transmission power of the second radiator 42 and the transmission power in the previous t time period is greater than or equal to a preset value, and the controller determines that the electronic device 1000 is in the vertical screen holding posture according to the transmission power of other radiators 40 (such as the first radiator 41) located outside the vertical screen holding area and working in the first frequency band is not reduced or is reduced very little. For example, the electronic device 1000 detects that the posture of the electronic device 1000 is the vertical screen posture through a sensor. The controller also monitors that the current transmission power of the second radiator 42 is 0.7 times (not limited to this data) of the transmission power in the previous t time period, and the controller determines that the second radiator 42 located in the vertical screen holding area is blocked or held by the hand according to the transmission power of other radiators 40 located outside the vertical screen holding area and working in the first frequency band is not reduced or is reduced very little. At this time, the posture of the electronic device 1000 is in the vertical screen holding posture.

[0171] Optionally, the at least one radiator 40 further includes a first radiator 41. The first radiator 41 is located outside the vertical screen holding area of ​​the electronic device 1000. For example, the first radiator 41 is located on the bottom frame 324 or the top frame 321. When the electronic device 1000 is in the vertical screen holding state, the first radiator 41 is not blocked or held by the hand.

[0172] The controller is used to control the second radiator 42 to operate in the first frequency band and be in the first operating state according to a third condition. The third condition includes that the main radiation direction of the directional pattern of the second radiator 42 when operating in the first frequency band is a second preset direction.

[0173] The controller is used to control the first radiator 41 to operate in the first frequency band and be in the first working state or the second working state according to a fourth condition. The second working state is that the first radiator 41 receives a radio frequency signal from the first front-end transmitting module 21 or the second front-end transmitting module 22. The fourth condition includes the main radiation direction of the second radiator 42, and the signal strength of the first radiator 41 operating in the first frequency band and being in the first working state or the second working state.

[0174] Specifically, when the electronic device 1000 is in a vertical screen holding state, it has several working modes.

[0175] For example, in the first working mode, the controller sets the main radiation direction of the radiation pattern of the second radiator 42 working in the first frequency band as the second preset direction. For example, the main radiation direction of the radiation pattern of the second radiator 42 in the first frequency band is toward the base station. At this time, the controller can control the second radiator 42 to receive the RF signals from the first front-end transmitting module 21 and the second front-end transmitting module 22 through the power division module 30, and be in a dual PA state to ensure that the first frequency band has a higher radiation power in the second preset direction.

[0176] For example, the second working mode is that the controller controls the main radiation direction of the directional pattern of the second radiator 42 working in the first frequency band to be not the second preset direction, for example, the main radiation direction of the directional pattern of the second radiator 42 in the first frequency band is not toward the base station, and the signal strength of the first radiator 41 working in the first frequency band and in the first working state or the second working state is greater than the signal strength of the second radiator 42 working in the first frequency band and in the second working state. At this time, the controller can control the first radiator 41 to be in the first working state (single PA state) or the second working state (dual PA state) to ensure that the first frequency band has a higher radiation power.

[0177] Optionally, the electronic device 1000 further includes a controller. The controller is configured to control the radiator 40 to be in the first working state when the strength of the received signal strength indication of the radiator 40 is less than or equal to a second preset strength.

[0178] Specifically, the present application does not make specific limitations on the second preset strength. When the controller detects that the strength of the received signal strength indication of all the radiators 40 is low, for example, 0.7 times the normal preset value (not limited to this data), it can be explained that the electronic device 1000 is in a weak field state or in a dense communication device state. At this time, the controller can control the radiator 40 to receive the RF signal from the first front-end transmission module 21 and the second front-end transmission module 22, and be in a dual PA state to ensure that the first frequency band has a higher radiation power. Among them, the radiator 40 includes but is not limited to any one or more of the aforementioned first radiator 41, the second radiator 42, the third radiator 43 and the fourth radiator 44.

[0179] In general technology, due to the layout of the mobile phone antenna or the RF layout, for example, the antenna radiator 40 is far away from the power amplifier, and the RF transmission line is long; or, there is a combiner, extractor, etc. between the antenna radiator 40 and the power amplifier, resulting in large insertion loss, which may cause a certain antenna RF front-end insertion loss to be large; or, a certain antenna is held dead, and the efficiency drops sharply, which leads to a decrease in the maximum transmission power when switching to this antenna; or it is impossible to switch to this antenna, reducing the transmission uplink coverage. Based on this, when the present application detects that a certain antenna is held dead and the efficiency drops sharply, it switches it to a dual PA state to make it have better efficiency and uplink coverage.

[0180] The present application sets a power divider, a first switch unit 71, a second switch unit 72 and a third switch 63 to realize that the radiator 40 works in a single PA state or a dual PA state. When the power detector detects that the maximum output power of a certain antenna radiator 40 is low, the two PAs work at the same time (that is, the first front-end transmitting module 21 and the second front-end transmitting module 22 work at the same time), and the first switch unit 71 and the second switch unit 72 are switched to switch the two identical (both in the first frequency band) transmission signals to the power division module 30 and combine them into one, and then switch to any one of the first radiator 41, the second radiator 42, the third radiator 43 and the fourth radiator 44 through the first switch 61, the second switch 62 and the third switch 63, for example, flexibly switch to a designated antenna, so as to enhance the uplink transmission power of the radiator 40, increase the uplink coverage, and solve the problem of low maximum power of the radiator 40.

[0181] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application, and these improvements and modifications are also regarded as the scope of protection of the present application.
