Detailed implementation manners

[0048] Next, the embodiments in the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0049] As described in the background art, in existing electronic devices, the communication performance of the antenna in the required frequency band still needs to be improved. The communication requirements of the electronic device in the WiFi frequency band will be used for illustration below.

[0050] As the main technology for indoor network coverage, WiFi is widely used inside consumer electronics such as mobile phones, tablets, and computers. The technological evolution of WiFi follows the IEEE 802 standard protocol and also has a clear product planning roadmap. From the early 11a / b / g / n to the current 11ac / ax / be. The latest WiFi technology has reached WiFi7. The frequency band has also reached the higher 6E band, up to 7.125 GHz. Among them, 11a / b / g / n of WiFi each represent different wireless network standards, and 11ac / ax / be of WiFi each represent different wireless network standards. They are all standards of wireless local area network technology, formulated by the IEEE 802.11 committee, and they are different in frequency, transmission speed, and technology. These continuous technological advancements reflect the growth of wireless network demand and the development of technology.

[0051] At the same time, with the rise of AI, the results of cloud computing need to be transmitted back in a timely manner, and the demand for WiFi will be further enhanced. At the same time, the interaction between IoT (Internet of Things) devices and terminals such as mobile phones will become more and more frequent, which will require stronger performance and stability.

[0052] To sum up, on the one hand, users' demand for improving the performance of WiFi antennas is becoming stronger and stronger. On the other hand, restricted by the limitations of WiFi chips and protocols, it is only possible to optimize the antenna performance under the existing hardware and protocols, which is very restricted.

[0053] In electronic devices, the communication performance of the WiFi frequency band can be improved through a multiple-input multiple-output (MIMO) design. However, due to the limitation of the internal space in electronic devices, it is impossible to set a large number of WiFi antennas in electronic devices to meet the MIMO design in the WiFi frequency band.

[0054] Reference Figure 1 , Figure 1 is a schematic diagram of the principle of multi-antenna layout in an electronic device. Figure 1 The electronic device shown includes four antennas 100. Two of the four antennas 100 are WiFi antennas, and the other two are cellular network antennas (Cellular WWAN antennas). Among them, the two cellular network antennas are the first cellular network antenna and the second cellular network antenna respectively.

[0055] The two cellular network antennas can be in a simple multiple-input multiple-output working mode. In this mode, the two cellular network antennas can form a 2×2 multiple-input multiple-output array antenna.

[0056] Alternatively, the two cellular network antennas can be in a hybrid operating mode that includes a main antenna operating mode and a multiple-input multiple-output (MIMO) operating mode. Among them, one cellular network antenna serves as the main antenna, and the other cellular network antenna serves as the auxiliary antenna. The operating mode can be selected through a switching switch. For example, if the main antenna is connected to the communication loop, the electronic device is in the main antenna operating mode. If the auxiliary antenna is connected to the communication loop, the two cellular network antennas form a 2×2 multiple-input multiple-output array antenna.

[0057] Among them, the two Wi-Fi antennas can form a 2×2 multiple-input multiple-output design. In Figure 1 the electronic device shown, the two Wi-Fi antennas and the two cellular network antennas operate separately without intersection. Based on this, the electronic device can at most achieve a 2×2 multiple-input multiple-output design in the Wi-Fi band. Limited by the internal layout space of the electronic device, it is impossible to further increase the number of Wi-Fi antennas to achieve stronger performance Wi-Fi band communication.

[0058] To solve the above problems, an embodiment of the present application provides an electronic device, which includes:

[0059] An antenna group, including: a first antenna and a second antenna;

[0060] A control circuit, which is used to receive a first radio frequency signal through the first antenna and is also used to control the operating mode of the second antenna; if the second antenna is in the first operating mode, the control circuit receives the first radio frequency signal through the second antenna, and if the second antenna is in the second operating mode, the control circuit receives a second radio frequency signal through the second antenna;

[0061] Among them, the first radio frequency signal and the second radio frequency signal have different frequency bands, and the communication distance of the first antenna in the first operating mode is different from that in the second operating mode. In the first operating mode, since the second antenna can receive the first radio frequency signal, the second antenna can be equivalently used as the first antenna. The first antenna and the antenna at different installation positions in the electronic device can be respectively used to receive the first radio frequency signal of different paths, which can enhance the reception ability of the first antenna for weak signals and improve its communication distance.

[0062] In the electronic device provided by the embodiment of the present application, the control circuit can receive the first radio frequency signal through the first antenna and can also control the operating mode of the second antenna. When the second antenna is in the first operating mode, the control circuit can receive the first radio frequency signal through the second antenna. When the second antenna is in the second operating mode, the control circuit can receive the second radio frequency signal through the second antenna. Among them, the first radio frequency signal and the second radio frequency signal have different frequency bands, and the communication distance of the first antenna in the first operating mode and the second operating mode is different.

[0063] When the second antenna is in the first working mode, the second antenna can receive a first-frequency signal, enabling the second antenna to be equivalent to the first antenna, thereby increasing the number of first antennas in the electronic device. In this way, the electronic device can implement MIMO design in the frequency band where the first radio frequency signal is located, improving the data transmission rate in this frequency band. Additionally, different first radio frequency signals on different paths can be received by multiple first antennas. By selecting the final signal path, the impact of multipath fading can be reduced. Through beamforming technology, the signal can be focused in the direction of the electronic device, reducing interference in other directions, thus enhancing signal reliability.

[0064] Moreover, since the electronic device can enhance the signal strength through beamforming and suppress signal attenuation through diversity technology when implementing MIMO design in the frequency band where the first radio frequency signal is located, based on this, the coverage range and communication distance of the received first radio frequency signal can be improved.

[0065] It should be noted that in the embodiments of the present application, the first-band signal includes but is not limited to a WiFi signal and can also be a signal in other frequency bands. The embodiments of the present application do not make any limitations in this regard.

[0066] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0067] Refer to Figure 2 and Figure 3 , Figure 2 which is a schematic diagram of the layout principle of antennas in an electronic device provided by an embodiment of the present application. Figure 3 For Figure 2 the equivalent circuit diagram of an antenna group in the electronic device shown.

[0068] As shown in Figure 2 and Figure 3 , the electronic device includes: an antenna group 103, and the antenna group 103 includes: a first antenna 101 and a second antenna 102; a control circuit 104, which is used to receive a first radio frequency signal through the first antenna 101 and is also used to control the working mode of the second antenna 102. When the second antenna 102 is in the first working mode, the control circuit 104 receives the first radio frequency signal through the second antenna 102. When the second antenna 102 is in the second working mode, the control circuit 104 receives a second radio frequency signal through the second antenna 102. Among them, the frequency bands of the first radio frequency signal and the second radio frequency signal are different, and the communication distance of the first antenna 101 in the first working mode is different from that in the second working mode.

[0069] The electronic device includes at least one antenna group 103, and the antenna group 103 includes at least one first antenna 101 and at least one second antenna 102. The number of the first antenna 101 and the second antenna 102 in the electronic device is not limited to Figure 1 As shown, the layout positions of the first antenna 101 and the second antenna 102 in the electronic device can be set according to requirements, not limited to Figure 1 As shown.

[0070] In the embodiment of the present application, when the second antenna 102 is in the first working mode, the second antenna 102 can receive a first frequency signal, so that the second antenna 102 can be equivalent to the first antenna 101 to increase the number of the first antennas 101 in the electronic device. In this way, the electronic device can implement MIMO design in the frequency band where the first radio frequency signal is located, and can improve the data transmission rate in this frequency band; it can also receive first radio frequency signals with different paths through multiple first antennas 101 respectively, reduce the influence of multipath fading by selecting the final signal path, and focus the signal in the direction of the electronic device through beamforming technology to reduce interference in other directions, thereby enhancing signal reliability.

[0071] For example, the electronic device may include an antenna group 103, and the antenna group 103 may include a first antenna 101 and a second antenna 102. When the second antenna 102 is in the first working mode, the second antenna 102 can be multiplexed for use as the first antenna 101 to increase the number of the first antennas 101 in the electronic device, so that the number of the first antennas 101 increases from one to two. Thus, the first antenna 101 and the second antenna 102 can be configured as a 2×2 multiple-input multiple-output array antenna corresponding to the target frequency band, and the target frequency band is the frequency band where the first radio frequency signal is located. In this way, the electronic device can implement a 2×2 multiple-input multiple-output design in the target frequency band through one first antenna 101.

[0072] Alternatively, the electronic device may also be as Figure 1 shown and include two antenna groups 103, and each antenna group 103 includes a first antenna 101 and a second antenna 102. When the second antenna 102 is in the first working mode, the two second antennas 102 can be multiplexed for use as the first antenna 101 to increase the number of the first antennas 101 in the electronic device, so that the number of the first antennas 101 increases from two to four. Thus, the two first antennas 101 and the two second antennas 102 can be configured as a 4×4 multiple-input multiple-output array antenna corresponding to the target frequency band. In this way, the electronic device can implement a 4×4 multiple-input multiple-output design in the target frequency band through one first antenna 101.

[0073] Among them, each antenna can achieve signal input and signal output through a time-division duplex design. Therefore, if two antennas are configured as a multiple-input multiple-output (MIMO) array antenna, a 2×2 MIMO array antenna can be formed; if four antennas are configured as a MIMO array antenna, a 4×4 MIMO array antenna can be formed.

[0074] Moreover, since the electronic device can enhance the signal strength through beamforming and suppress signal attenuation through diversity techniques when implementing MIMO design in the frequency band where the first radio frequency signal is located, the coverage range and communication distance of the received first radio frequency signal can be improved based on this.

[0075] In addition, in a conventional electronic device, the second antenna 102 generally can only operate in a communication mode based on the second radio frequency signal. In the embodiments of the present application, the second antenna 102 can perform a switching of operating modes and can operate in a first operating mode of receiving the first radio frequency signal or in a second operating mode of receiving the second radio frequency signal according to requirements, so that the electronic device can switch the operating mode of the second antenna 102 based on the current communication environment, so that the communication performance based on the first radio frequency signal can better adapt to the current communication environment and can better meet the communication requirements based on the first radio frequency signal. Among them, the first radio frequency signal includes, but is not limited to, a WiFi signal.

[0076] The electronic device may include multiple second antennas 102. While some of the second antennas 102 are in the first operating mode and are multiplexed as the first antenna 101 to enhance the communication ability of the first radio frequency signal, another part of the second antennas 102 are in the second operating mode. In this way, the electronic device can not only multiplex some of the second antennas 102 as the first antenna 101 to enhance the communication ability of the first radio frequency signal, but also receive the second radio frequency signal through another part of the second antennas 102, so that the electronic device can communicate based on the second radio frequency signal.

[0077] In a scenario where the electronic device does not receive the first radio frequency signal, all the second antennas 102 can be in the second operating mode for receiving the second radio frequency signal. At this time, all the second antennas 102 are used to construct a second antenna array with multiple inputs and multiple outputs. In a scenario where the electronic device has the first radio frequency signal to receive, at least some of the second antennas 102 can be in the second operating mode, and these at least some of the second antennas 102 can be equivalent to the first antenna 101, thereby increasing the number of the first antennas 101, so that there are more antennas in the electronic device as the first antenna 101 to construct a multiple-input multiple-output antenna array for receiving the first radio frequency signal, and improving the communication performance of the electronic device through the first radio frequency signal.

[0078] In one implementation, the first radio frequency signal may be a WiFi signal, and the second radio frequency signal is a signal in a frequency band different from the WiFi signal. The first antenna 101 may be a WiFi antenna. The second antenna 102 may be a cellular network antenna, which is used to receive the WiFi signal in the first working mode and receive the second radio frequency signal in the second working mode. The electronic device may include two first antennas 101 and four second antennas 102.

[0079] In scenarios without WiFi communication requirements, such as outdoors, the four second antennas 102 may all operate in the second working mode, and the four second antennas 102 may be configured as a 4×4 multiple-input multiple-output antenna array for receiving the second radio frequency signal.

[0080] In scenarios with WiFi communication requirements, such as indoors, two of the four second antennas 102 can be controlled to operate in the first working mode, and the other two second antennas 102 can be controlled to operate in the second mode. At this time, the two second antennas 102 operating in the first working mode and the two first antennas 101 can be configured as a 4×4 multiple-input multiple-output antenna array for receiving the first radio frequency signal to improve the communication performance of the electronic device based on the WiFi signal. At the same time, the other two second antennas 102 operating in the second working mode can also be configured as a 2×2 multiple-input multiple-output antenna array for receiving the second radio frequency signal, so that the electronic device can communicate based on the second radio frequency signal while achieving high-performance WiFi signal communication.

[0081] In the above method, the four cellular network antennas can be dynamically allocated. In scenarios with WiFi communication requirements, two cellular network antennas can be used to receive the WiFi signal to implement a 4×4 multiple-input multiple-output antenna array for the WiFi signal to enhance the communication performance of the WiFi signal. Moreover, in this method, when both of the two cellular network antennas are in the second working mode, a 2×2 multiple-input multiple-output antenna array for the second radio frequency signal can also be implemented based on these two cellular network antennas. In this method, the cellular network antennas need to receive the WiFi signal in scenarios with WiFi communication requirements, and these two cellular network antennas are only used as normal connections without core data services.

[0082] In other methods, the electronic device may also include one or more second antennas 102. In this method, all the second antennas 102 can be controlled to be in the first working mode at the same time, or in the second working mode at the same time. Taking the first radio frequency signal as a WiFi signal as an example, in scenarios without WiFi communication requirements, all the second antennas 102 can be controlled to be in the second working mode; in scenarios with WiFi communication requirements, all the second antennas 102 can be controlled to be in the first working mode.

[0083] Reference Figure 4 , Figure 4 is a schematic structural diagram of a control circuit in an electronic device provided by an embodiment of the present application. On the basis of the above method, Figure 4 In the method shown, the control circuit 104 includes: a first antenna circuit 105 connected to the first antenna 101, capable of receiving a first radio frequency signal in a first frequency band based on the first antenna circuit 105; a second antenna circuit 106 connected to the second antenna 102, and the second antenna circuit 106 is used to control the second antenna 102 to be in a first working mode or a second working mode.

[0084] In Figure 4 In the method shown, an appropriate antenna circuit can be connected to the first antenna 101 and the second antenna 102 respectively, so that the first antenna 101 can receive a first radio frequency signal based on the first antenna circuit 105, and the second antenna 102 can select a working mode through the second antenna circuit 106, so as to control the second antenna 102 to be in the first working mode through the second antenna circuit 106 to receive the first radio frequency signal, or control the second antenna 102 to be in the second working mode to receive a second radio frequency signal.

[0085] Reference Figure 5 , Figure 5 is another schematic structural diagram of a control circuit in an electronic device provided by an embodiment of the present application. On the basis of the method shown in Figure 4 On the basis of the method shown, Figure 5 In the method shown, the second antenna circuit 106 includes a first branch 107 and a second branch 108. If in the first working mode, the first branch 107 is turned on and the second branch 108 is turned off, and the second antenna 102 receives the first radio frequency signal through the first branch 107; if in the second working mode, the first branch 107 is turned off and the second branch 108 is turned on, and the second antenna 102 receives the second radio frequency signal through the second branch 108.

[0086] In Figure 5 In the method shown, the second antenna circuit 106 can simply switch the conduction states of the first branch 107 and the second branch 108 with the second antenna 102, and then the switching of the working mode of the connected second antenna 102 can be realized, so that the connected second antenna 102 can be switched between the first working mode and the second working mode. The control method of the working mode of the second antenna 102 is simple and easy to implement.

[0087] Reference Figure 6 , Figure 6 is still another schematic structural diagram of a control circuit in an electronic device provided by an embodiment of the present application. On the basis of the method shown in Figure 5 On the basis of the method shown, Figure 6In the shown manner, the circuit between the first antenna circuit 105 and the second antenna circuit 106 is separated so that the first radio frequency signals in the first branch 107 and the first antenna circuit 105 are output through independent signal channels respectively. In this manner, for the same control circuit 104, the first antenna circuit 105 and the second antenna circuit 106 are two independent circuits.

[0088] In Figure 6 the shown manner, the control circuit 104 includes three signal ports, which can be represented by A1, A2, and B1 respectively.

[0089] The first antenna 101 can be connected through the first antenna circuit 105 and the signal port A1. After the first radio frequency signal received by the first antenna 101 is processed by the first antenna circuit 105, it is output through the signal port A1.

[0090] The second antenna 102 is connected to the signal port A2 through the first branch 107 in the second antenna circuit 106, and is connected to the signal port B1 through the second branch 108 in the second antenna circuit 106. When the first branch 107 and the second antenna 102 are conducting, and the second branch 108 and the second antenna 102 are open-circuited, the first radio frequency signal received by the second antenna 102 is processed by the first branch 107 and then output through the signal port A2. When the first branch 107 and the second antenna 102 are open-circuited, and the second branch 108 and the second antenna 102 are conducting, the second radio frequency signal received by the second antenna 102 is processed by the second branch 108 and then output through the signal port B1.

[0091] In one manner, the first radio frequency signal can be a WiFi signal, and the second radio frequency signal can be a signal applicable to a wireless wide area network (WWAN). At this time, as Figure 6 shown, both the signal port A1 and the signal port A2 can be WiFi signal ports, and the signal port B1 is a WWAN signal port.

[0092] Optionally, in one manner, as Figure 6 shown, in the same second antenna circuit 106, the first branch 107 and the second branch 108 are connected to the second antenna 102 through the first switch SW1. In this manner, the second antenna circuit 106 can realize the on-off control of the second antenna 102 with the first branch 107 and the second branch 108 through the first switch SW1, and the control manner of the second antenna circuit 106 is simple.

[0093] Optionally, at least one of the first branch 107 and the second branch 108 has a phase adjustment component PS, which can be a phase converter. The phase adjustment component PS is used to dynamically adjust the phase of the signal in the branch where it is located, achieve beamforming and signal optimization, and can form constructive interference to enhance the signal. In Figure 6 the illustrated manner, taking the first branch 107 having the phase adjustment component PS as an example for illustration.

[0094] For example, if the electronic device includes two antenna groups 103, and each antenna group 103 includes a first antenna 101 and a second antenna 102, when using Figure 6 the illustrated control circuit 104, the structure of the control circuit 104 of the electronic device can be as Figure 7 illustrated.

[0095] Referring to Figure 7 , Figure 7 which is a schematic structural diagram of a control circuit in another electronic device provided by an embodiment of the present application. On the basis of the Figure 6 illustrated manner, in the Figure 7 illustrated manner, the electronic device includes two antenna groups 103, and each antenna group 103 is connected to a control circuit 104 as Figure 6 illustrated. In the Figure 7 illustrated manner, when the two second antennas 102 are both controlled to operate in the first operating mode through the control circuit 104, the two second antennas 102 and the two first antennas 101 can be used to simultaneously receive the first radio frequency signal. Since the four antennas respectively output signals through separate signal ports, these four antennas can be configured as a 4×4 MIMO antenna array, thereby improving the performance of the electronic device when communicating based on the first radio frequency signal.

[0096] Referring to Figure 8 , Figure 8 which is a schematic structural diagram of a control circuit in another electronic device provided by an embodiment of the present application. On the basis of the Figure 5 illustrated manner, Figure 8In the shown manner, the first branch 107 is connected to the first antenna circuit 105; if the second antenna 102 is in the first working mode, the electronic device can control the circuit between the first branch 107 and the first antenna circuit 105 to conduct, so that the first radio frequency signal in the first branch 107 and the first antenna circuit 105 is output based on the same signal channel. In this manner, in the same antenna group 103, when the second antenna 102 is in the first working mode, if the second antenna 102 and the first antenna 101 output signals based on the first signal channel, the communication performance of the electronic device based on the first radio frequency signal can be enhanced by the second antenna 102. The electronic device can simultaneously receive the first radio frequency signals in different directions through the first antenna 101 and the second antenna 102, improving the reception ability of the first radio frequency signal. Signal fluctuations caused by blockage of obstacles and co-frequency interference can be reduced through multi-path signal superposition or selective reception, which is suitable for complex multi-path communication environments.

[0097] Optionally, as Figure 8 shown, the first antenna circuit 105 includes: a second switching switch SW2 and a third switching switch SW3; a third branch 109 and a fourth branch 110, and the third branch 109 and the fourth branch 110 are connected in parallel between the second switching switch SW2 and the third switching switch SW3.

[0098] If the second antenna 102 is in the first working mode, the circuit between the first antenna 101 and the third branch 109 conducts, the first branch 107 and the third branch 109 conduct, and the first radio frequency signal is received through the third branch 109. In this manner, the second antenna 102 can also be connected to the first branch 107 and the second branch 108 respectively through the first switching switch SW1. When the second antenna 102 is in the first working mode, the second antenna 102 conducts through the first switching switch SW1 and the first branch 107. When the second antenna 102 is in the second working mode, the second antenna 102 conducts through the first switching switch SW1 and the second branch 108.

[0099] If the second antenna 102 is in the second working mode, the first antenna 101 conducts with the fourth branch 110, the first radio frequency signal is received through the fourth branch 110, and the first branch 107 is open-circuited with the third branch.

[0100] Wherein, the first antenna 101 is connected to the third branch 109 and the fourth branch 110 respectively through the second switching switch SW2. If the second antenna 102 is in the second working mode, the first antenna 101 conducts with the fourth branch 110 through the second switching switch SW2 to transmit signals through the fourth branch 110. If the second antenna 102 is in the first working mode, the first antenna 101 conducts with the third branch 109 through the second switching switch SW2 to transmit signals through the third branch 109.

[0101] The third branch 109 and the fourth branch 110 are connected to the same signal port A1 through the third switching switch SW3. The second branch 108 is connected to a separate signal port B1.

[0102] As Figure 8 shown, the third branch 109 includes a duplexer Dip. In the third branch 109, the second switching switch SW2 is connected through the duplexer Dip and the third switching switch SW3, and the first branch 107 is connected through the duplexer Dip and the third switching switch SW3.

[0103] In one way, as Figure 8 shown, if the second antenna 102 is in the first operating mode, the first radio frequency signals in the first branch 107 and the first antenna circuit 105 are output based on the same signal channel, and this signal channel is connected to the signal port A1, that is, the first radio frequency signals in the first branch 107 and the first antenna circuit 105 are signal output based on the signal port A1.

[0104] For example, the electronic device includes two antenna groups 103, and each antenna group 103 includes a first antenna 101 and a second antenna 102. When using Figure 8 the control circuit 104 shown, the structure of the control circuit 104 of the electronic device can be as Figure 9 shown.

[0105] Referring to Figure 9 , Figure 9 This is a schematic diagram of the structure of the control circuit in another electronic device provided by the embodiment of the present application. On the basis of the Figure 8 shown method, Figure 9 In the method shown, the electronic device includes two antenna groups 103, and each antenna group 103 is connected to a control circuit 104 as Figure 8 shown. In the Figure 9 shown method, when the two second antennas 102 are both controlled to work in the first operating mode through the control circuit 104, the two second antennas 102 and the two first antennas 101 can be used to simultaneously receive the first radio frequency signal. Since the first antenna 101 and the second antenna 102 in the same antenna group 103 perform signal output through the same signal port A1, these four antennas can be configured as a 2×2 MIMO antenna array, thereby improving the performance of the electronic device when communicating based on the first radio frequency signal.

[0106] Optionally, in the Figure 8 and Figure 9 shown methods, if the second antenna 102 is in the second operating mode, the circuit between the first branch 107 and the first antenna circuit 105 is open, and the second antenna 102 is conductive with the second branch 108, and the second radio frequency signal can be received through the second antenna 102.

[0107] In one way, as Figure 8 and Figure 9 shown, when the second antenna 102 is in the second working mode, the first antenna 101 and the second antenna 102 in the same antenna group 103 can perform signals based on the same signal channel, that is, both output signals through the same signal port.

[0108] In another way, the structure of the control circuit 104 can also be as Figure 10 shown.

[0109] Referring to Figure 10 , Figure 10 a schematic diagram of the structure of the control circuit in another electronic device provided by the embodiments of the present application. Based on the way shown in Figure 8 , in the way shown in Figure 10 , the first branch 107 has a preset signal port A2, and the preset signal port A2 is connected to the second antenna 102 through the first switch SW1. If the second antenna 102 is in the first working mode, the electronic device can also control the circuit between the first branch 107 and the first antenna circuit 105 to be open, so that the first branch 107 and the antenna circuit independently transmit the first radio frequency signal respectively, and the signal can be output through the preset signal port A2. In this way, for the second antenna 102 corresponding to the second working mode, the electronic device can select that the first branch 107 and the first antenna circuit 105 output signals based on the same signal port, or select that the first branch 107 and the first antenna circuit 105 output signals based on different signal ports respectively. If the electronic device selects that the first branch 107 and the first antenna circuit 105 output signals based on the same signal port, at this time, the same control circuit 104 receives the first radio frequency signals from the first antenna 101 and the second antenna 102 in the same antenna group 103 at the same time, and combines and outputs the two signals through the same signal port, which can reduce power consumption and enhance the weak signal reception ability.

[0110] If the electronic device selects the first branch 107 and the first antenna circuit 105 to output signals based on different signal ports respectively, at this time, the same control circuit 104 receives the first radio frequency signal simultaneously based on the first antenna 101 and the second antenna 102 in the same antenna group 103, and outputs the two signals through separate signal ports respectively. A multiple-input multiple-output antenna array can be constructed with a larger number of antennas to improve the transmission rate. In this way, if the electronic device includes two first antennas 101 and two second antennas 102, when the two second antennas 102 are in the first working mode, the two first antennas 101 and the two second antennas 102 can be configured as a 4×4 multiple-input multiple-output antenna array for receiving the first radio frequency signal. If the two second antennas 102 are in the second working mode, the two first antennas 101 are configured as a 2×2 multiple-input multiple-output antenna array for receiving the first radio frequency signal.

[0111] Optionally, as Figures 6 - 10 shown, one of the first branch 107 and the second branch 108 includes a phase adjustment component PS.

[0112] From the above description, it can be seen that in the electronic device provided by the embodiments of the present application, the second antenna 102 can be equivalent to the first antenna 101. If the electronic device includes two first antennas 101 and two second antennas 102, for the scenario of receiving the first radio frequency signal, through Figure 6 , Figure 7 or Figure 11 shown methods, the original 2×2 multiple-input multiple-output antenna array can be expanded to a 4×4 multiple-input multiple-output antenna array for receiving the first radio frequency signal. When the electronic device communicates based on WiFi signals, an electronic device with two WiFi antennas can be enabled to implement a 4×4 multiple-input multiple-output antenna array for receiving WiFi signals.

[0113] If the electronic device includes two first antennas 101 and two second antennas 102, for the scenario of receiving the first radio frequency signal, the weak signal reception ability can also be enhanced based on Figure 8 or Figure 9 shown methods.

[0114] Based on the electronic device provided in the above embodiments, another embodiment of the present application further provides a communication method for the above electronic device. The communication method is as Figure 11 shown.

[0115] Referring to Figure 11 , Figure 11 is a schematic flowchart of a communication method for an electronic device provided by an embodiment of the present application. The communication method includes:

[0116] Step S11: If the second antenna 102 is in the first working mode, receive the first radio frequency signal through the first antenna 101 and the second antenna 102 simultaneously.

[0117] Step S12: If the second antenna 102 is in the second working mode, receive the second radio frequency signal through the second antenna 102 and receive the first radio frequency signal through the first antenna 101.

[0118] Wherein, the frequency bands of the first radio frequency signal and the second radio frequency signal are different, and the communication distance of the first antenna 101 in the first working mode is different from the communication distance of the first antenna 101 in the second working mode.

[0119] Optionally, in the above communication method, the electronic device includes a plurality of second antennas 102; if the target condition is satisfied, control a part of the second antennas 102 to be in the first working mode and control another part of the second antennas 102 to be in the second working mode; if the target condition is not satisfied, control all the second antennas 102 to be in the second working mode. In this way, not only can a part of the second antennas 102 be equivalent to the first antenna 101 to enhance the communication performance of the electronic device based on the first radio frequency signal, but also the electronic device can communicate based on another part of the second antennas 102 based on the second radio frequency signal.

[0120] Wherein, if the electronic device obtains a preset instruction, the target condition is satisfied, and the preset instruction represents that the user manually inputs an operation for the second antenna 102 to enter the second working mode. Or, if the electronic device executes an application program that needs to communicate based on the first radio frequency signal, the target condition is satisfied.
