Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an electronic device. Background Technology

[0002] With the development of communication technology, users have increasingly higher requirements for the communication quality of electronic devices. However, at present, most frequency band antennas still have blind spots in antenna pattern coverage, and the improvement of communication quality is still limited. Summary of the Invention

The first antenna, the second antenna, and at least some of the third antennas are connected to the switching circuit. At most some of the third antennas are connected to the second radio frequency circuit.

[0009] Specifically, when the electronic device establishes a connection with the first communication network, the switching circuit connects at least one of the first antenna and the second antenna to the first radio frequency circuit; when the electronic device disconnects from the first communication network, the switching circuit connects at least one of the first antenna and the at least part of the third antenna to the second radio frequency circuit.

Through the switching circuit, when the electronic device is connected to the first communication network, at least one of the first antennas and the second antenna is connected to the first RF circuit. When the electronic device is disconnected from the first communication network, the switching circuit connects at least one of the first antennas and at least some of the third antennas to the second RF circuit. Thus, the first antenna combined with the second antenna can achieve phase scanning of the antennas of the first communication network, and the first antenna combined with the third antenna can achieve phase scanning of the antennas of the second communication network. This allows the electronic device to simultaneously meet the phase scanning requirements of different networks, effectively complementing the multiple antenna patterns of the first and second frequency band signals, and improving the transmission and reception performance of the first and second frequency band signals.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] The electronic devices involved in the embodiments of this application have wireless communication capabilities and can be handheld devices, in-vehicle devices, smart cars, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., mobile phones), mobile stations (MS), etc. For ease of description, the devices mentioned above are collectively referred to as electronic devices.

[0028] Figure 1 This is a structural block diagram of an electronic device according to an embodiment, with reference to... Figure 1 In this embodiment, the electronic device includes: a switching circuit 10, a first radio frequency circuit 20, a second radio frequency circuit 30, and an antenna group.

[0029] A first radio frequency (RF) circuit 20 is used to support the transmission and reception of signals in a first frequency band of a first communication network; a second RF circuit 30 is used to support the transmission and reception of signals in a second frequency band of a second communication network. The first RF circuit 20 and the second RF circuit 30 may each include at least one transceiver link, which includes a receiving link for supporting signal reception processing and a transmitting link for supporting signal transmission processing.

[0030] An antenna array can be understood as a combination of multiple antennas in different locations, including a first antenna (ANT1 in the figure), a second antenna (ANT2 in the figure), and multiple third antennas. Figure 1 The following illustration uses four third antennas as an example, namely ANT3, ANT4, ANT5, and ANT6 in the figure (this is for illustrative purposes only and is not intended to be limiting). The first antenna supports operation in either the first or second frequency band, the second antenna supports operation in the first frequency band, and the third antenna supports operation in the second frequency band. The first antenna, the second antenna, and at least a portion of the third antennas are connected to the switching circuit 10, and at most a portion of the third antennas are connected to the second radio frequency circuit 30. For example, the second and third antennas can be understood as existing antennas in the electronic device, which have blind spots in antenna pattern coverage; the first antenna can be understood as a multi-functional antenna, which can serve as both a phase-scanning antenna for the first communication network and a phase-scanning antenna for the second communication network, achieving effective compensation for multiple radiation patterns.

[0031] The first and second communication networks differ. For example, the first communication network includes a Wi-Fi communication network, and the first frequency band includes one or more of the following: 2.4 GHz Wi-Fi band, 5 GHz Wi-Fi band, 2.4 GHz BT band, and BT Wi-Fi band. The second communication network includes a cellular communication network, and the second frequency band includes one or more of the following: mid-frequency band and high-frequency band of 4G network, or it may include one or more of the following: mid-frequency band, high-frequency band, and ultra-high-frequency band of 5G network. For example, the first frequency band includes the 2.4 GHz Wi-Fi band, and the second frequency band includes the B40 / N40 band and the B41 / N41 band; or the first frequency band includes the 2.4 GHz Wi-Fi band, and the second frequency band includes the B40 / N40 band, the B41 / N41 band, and the N78 band. In other embodiments, the first communication network may also be a Bluetooth (BT) communication network or other communication networks, which will not be described in detail here.

[0032] The switching circuit 10 is connected to the first radio frequency circuit 20, the second radio frequency circuit 30, the first antenna, the second antenna, and at least part of the third antenna, and at most part of the third antenna is connected to the second radio frequency circuit 30. It can be understood that each antenna in the antenna group is an antenna in a different position, so the radiation patterns of the multiple antennas are different, and different scenarios may require different antenna radiation patterns to be matched.

[0033] When the first RF circuit 20 and the second RF circuit 30 are switchably connected to different antennas via the switching circuit 10, signal reception and transmission in different directions can be achieved. On the one hand, the radiation direction with better signal quality can be selected for signal transmission and reception based on different holding scenarios, communication scenarios, etc. On the other hand, when connected to multiple antennas, effective complementarity of multiple radiation patterns can be achieved, further improving the transmission and reception quality of the electronic device and increasing revenue. In addition, by switching the antennas via the switching circuit 10, the first antenna can be used as both a phase-scanning antenna for the first communication network and a phase-scanning antenna for the second communication network. Thus, by switching, different network signals can be transmitted and received, reducing the number of high-cost extractors required when multiplexing the first antenna for two different network signals, thereby reducing costs.

[0034] For example, when an electronic device establishes a connection with a first communication network, the switching circuit 10 can connect at least one of the first antenna and the second antenna to the first radio frequency circuit 20. At this time, the first antenna mainly operates in the first frequency band, and the first radio frequency circuit 20 can switch between transmitting and receiving signals in the first frequency band using at least one of the first antenna and the second antenna. The transmission and reception of the first frequency band signal can cover different radiation patterns according to actual needs, improving the transmission and reception performance of the first frequency band signal. Specifically, when one of the first antenna and the second antenna is connected to the first radio frequency circuit 20, the first radio frequency circuit 20 can select a radiation direction with better signal quality for signal transmission and reception using that antenna. When both the first antenna and the second antenna are connected to the first radio frequency circuit 20, the first radio frequency circuit 20 can support multiple transmissions and MIMO (Multiple Input Multiple Output) reception through the aforementioned antennas, achieving effective complementarity of multiple radiation patterns for the first frequency band signal through multiple antennas.

[0035] For example, when the electronic device establishes a connection with the first communication network, the switching circuit 10 can also connect at least one of the third antennas to the second radio frequency circuit 30, so that the second radio frequency circuit 30 also transmits and receives signals in the second frequency band, so that the electronic device supports both the first and second communication networks simultaneously.

[0036] For example, when the electronic device is disconnected from the first communication network, the switching circuit 10 can connect at least one of the first antenna and at least a portion of the third antenna to the second radio frequency circuit 30. In this case, the first antenna primarily operates in the second frequency band, and the second radio frequency circuit 30 can switch between transmitting and receiving signals in the second frequency band via at least one of the first antenna and at least a portion of the third antenna. The transmission and reception of the second frequency band signal can cover different radiation patterns according to actual needs, improving the transmission and reception performance of the second frequency band signal. Specifically, when one of the first antenna and at least a portion of the third antenna is connected to the second radio frequency circuit 30, the second radio frequency circuit 30 can select a radiation direction with better signal quality for signal transmission and reception via that antenna. When the first antenna and at least a portion of the third antenna are respectively connected to the second radio frequency circuit 30, the second radio frequency circuit 30 can achieve multiple transmissions and MIMO reception via the aforementioned antennas, effectively complementing multiple radiation patterns of the second frequency band signal through multiple antennas.

[0037] For example, taking a Wi-Fi network as the first communication network, the initial state of the second antenna can be assumed to be connected to the first radio frequency circuit 20. When the second antenna receives a Wi-Fi hotspot signal, it can be determined that the electronic device has established a connection with the first communication network; when the electronic device determines that the Wi-Fi hotspot is turned off, or when neither the first antenna nor the second antenna receives a Wi-Fi hotspot signal, it can be determined that the electronic device has disconnected from the first communication network. It is understood that in other embodiments, it is possible to determine whether the electronic device has established a connection or disconnected from the first communication network in other ways, which will not be described in detail in this embodiment.

[0038] The electronic device provided in this embodiment includes a switching circuit 10, a first radio frequency circuit 20 supporting the transmission and reception of signals in a first frequency band of a first communication network, a second radio frequency circuit 30 supporting the transmission and reception of signals in a second frequency band of a second communication network, and an antenna group. The antenna group includes a first antenna, a second antenna, and multiple third antennas. The first antenna can operate in both the first and second frequency bands. Through the switching circuit 10, when the electronic device is connected to the first communication network, at least one of the first antenna and the second antenna is connected to the first radio frequency circuit 20. When the electronic device is disconnected from the first communication network, the switching circuit 10 connects at least one of the first antenna and at least some of the third antennas to the second radio frequency circuit 30. Thus, the first antenna combined with the second antenna can achieve phase scanning of the antennas of the first communication network, and the first antenna combined with the third antenna can achieve phase scanning of the antennas of the second communication network. This allows the electronic device to simultaneously meet the phase scanning requirements of different networks, effectively complementing multiple radiation patterns of the first and second frequency band signals, and improving the transmission and reception performance of the first and second frequency band signals. For example, when the first frequency band includes the 2.4 GHz Wi-Fi band and the second frequency band includes the N41 and N78 bands, the first antenna can function as both a phase-scanning antenna for 2.4 GHz Wi-Fi and a phase-scanning antenna for cellular N41 and N78 bands. This allows the electronic device to simultaneously meet the phase-scanning requirements of the three major 5G frequency bands used by domestic operators. Furthermore, by switching between different network signals, the first antenna can support the transmission and reception of different network signals, reducing the number of costly extractors required when multiplexing the first antenna for two different network signals, thus lowering costs.

[0039] In one embodiment, when the electronic device is disconnected from the first communication network, the switching circuit 10 uses the first target antenna among the first antenna and at least part of the third antenna as the main antenna of the second communication network and connects it to the second radio frequency circuit 30, where the target antenna has the best signal quality among the first antenna and multiple antennas.

[0040] In this configuration, when the electronic device is disconnected from the first communication network, the first antenna can function as a phase-scanned antenna for the second communication network. The switching circuit 10, by performing phase-scanning switching on the first antenna and at least a portion of the third antennas, can determine the first target antenna with the best signal quality from among the first antenna and at least a portion of the third antennas. This first target antenna is then used as the main antenna for the second communication network, and is connected to the second radio frequency circuit 30. This allows the second radio frequency circuit 30 and the antenna to jointly transmit and receive signals in the second frequency band. Therefore, through the cooperation between the switching circuit 10, the first antenna, and at least a portion of the third antennas, the electronic device can dynamically select the antenna with better signal quality for connection when switching from the first communication network to the second communication network, thus maintaining good signal quality at all times.

[0041] In one embodiment, there are four third antennas, which are connected to the switching circuit 10 respectively. When the electronic device is disconnected from the first communication network, the switching circuit 10 connects the first antenna and four of the four third antennas to the second radio frequency circuit 30, so that the electronic device supports the transmission of the second frequency band signal and 4*4 MIMO reception processing.

[0042] It is understandable that the switching circuit 10 can select the four antennas to be connected to the second radio frequency circuit 30 from the first antenna and the four third antennas, depending on the transmission and reception requirements of the second communication network of the electronic device. For example, the four antennas with higher signal quality from the first antenna and the four third antennas can be connected to the second radio frequency circuit 30 to realize the transmission of the second frequency band signal and 4*4 MIMO reception processing.

[0043] In this embodiment, the switching circuit 10 connects the first antenna and four of the four third antennas to the second radio frequency circuit 30, enabling the electronic device to support the transmission of second frequency band signals and 4*4 MIMO reception processing. This allows four antennas to be selected from a larger pool of antennas as the transmitting and receiving antennas for the second frequency band signals, enabling the electronic device to achieve effective complementarity of multiple radiation patterns of the second frequency band signals and improve the transmission and receiving performance of the second frequency band signals.

[0044] In one embodiment, there are four third antennas. Three of the four third antennas are connected to the second radio frequency circuit 30, and the remaining one of the four third antennas is connected to the switching circuit 10. When the electronic device is disconnected from the first communication network, the switching circuit 10 connects the first antenna and one of the remaining antennas to the second radio frequency circuit 30, so that the electronic device supports 4*4 MIMO reception processing of the second frequency band signal.

[0045] It is understood that the switching circuit 10 selects a target antenna from the first antenna and the remaining third antenna to connect to the second radio frequency circuit 30. This target antenna, together with the three third antennas directly connected to the second radio frequency circuit 30, supports the transmission of second-band signals and 4x4 MIMO reception processing. For example, this target antenna can be determined according to the transmission and reception requirements of the electronic device's second communication network. For instance, the target antenna with the higher signal quality from the first antenna and the remaining third antenna can be connected to the second radio frequency circuit 30 to jointly achieve the transmission of second-band signals and 4x4 MIMO reception processing with the other three antennas.

[0046] In this embodiment, the switching circuit 10 connects one of the first antenna and one of the third antennas to the second radio frequency circuit 30, so that it can work with the other three antennas to transmit the second frequency band signal and receive 4*4 MIMO signals. Thus, based on the antennas fixedly connected to the second radio frequency circuit 30, the switchable antenna can be combined to achieve effective pattern complementarity and improve the transmission and reception performance of the second frequency band signal.

[0047] In one embodiment, when the electronic device establishes a connection with the first communication network, the switching circuit 10 connects the second target antenna in the first antenna and the second antenna to the first radio frequency circuit 20, and the signal quality of the second target antenna in the first antenna and the second antenna is optimal.

[0048] In this configuration, when the electronic device establishes a connection with the first communication network, the first antenna can function as a phase-scanned antenna of the first communication network. The switching circuit 10, by performing phase-scanning switching between the first and second antennas, can determine the second target antenna with the best signal quality from the first and second antennas. This second target antenna serves as the main antenna of the first communication network, and is then connected to the first radio frequency circuit 20. This allows the first radio frequency circuit 20 and the second antenna to jointly transmit and receive signals in the first frequency band. Therefore, through the cooperation between the switching circuit 10, the first antenna, and the second antenna, the electronic device can dynamically select the antenna with better signal quality for connection when switching to the first communication network, thus maintaining good signal quality at all times.

[0049] In one embodiment, the switching circuit 10 switches between different antennas connected to the radio frequency circuit, enabling the radio frequency circuit and the antennas connected to the radio frequency circuit to transmit and / or receive signals, in order to determine the target antenna with the optimal signal quality.

[0050] In this process, transmission power information can be obtained through signal transmission, and the target antenna with optimal signal quality can be determined based on the transmission power information. For example, taking the second radio frequency circuit 30 as an example, the switching circuit 10 can switch each antenna to be connected to the second radio frequency circuit 30. The second radio frequency circuit 30 supports the sequential transmission of second frequency band signals to each connected antenna to switch different transmission antennas. Thus, the antennas that are connected can be determined from the first antenna and at least some of the third antennas based on the transmission power information of different transmission antennas.

[0051] In this process, network information of the received signal can be obtained through signal reception, and the target antenna with optimal signal quality can be determined based on the network information. For example, taking the second radio frequency circuit 30 as an example, the switching circuit 10 can switchably connect each antenna to the second radio frequency circuit 30, and determine the four antennas from the first antenna and the four third antennas based on the network information of the received second frequency band signal from each antenna. The network information may include raw and processed information associated with wireless performance metrics of the received second frequency band signal, such as signal strength, received power, Reference Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Signal-to-Noise Ratio (SNR), Rank of the MIMO channel matrix, Carrier-to-Interference Plus Noise Ratio (RS-CINR), Frame Error Rate, Bit Error Rate, Reference Signal Reception Quality (RSRQ), etc.

[0052] In one embodiment, when the electronic device establishes a connection with the first communication network, the switching circuit 10 connects the first antenna and the second antenna to the first radio frequency circuit 20, respectively, so that the electronic device supports the transmission of the first frequency band signal and 2*2 MIMO reception processing.

[0053] When the electronic device establishes a connection with the first communication network, the first antenna can act as the phase-scanning antenna of the first communication network. The first antenna and the second antenna are respectively connected to the first radio frequency circuit 20 through the switching circuit 10, so that the electronic device supports the transmission of the first frequency band signal and 2*2 MIMO reception processing, further improving the transmission and reception quality of the first frequency band signal.

[0054] In one embodiment, such as Figure 2 As shown, the electronic device also includes: a top frame 411, a first side frame 413, a bottom frame 414, and a second side frame 414 connected end to end. The top frame 411, the first side frame 413, the bottom frame 414, and the second side frame 414 surround the middle plate. Four third antennas are respectively located on the top frame 411, the first side frame 413, the bottom frame 414, and the second side frame 414 (e.g., Figure 3 As shown, for easy reference, Figure 3(The border is not shown in the image); the first antenna is located at the corner between any two adjacent borders, and the second antenna is located on any border with a third antenna between it and the first antenna. Thus, each antenna is distributed in different borders or at different positions on the same border, resulting in different antenna patterns.

[0055] In this design, the four third antennas of the second communication network are distributed on different frames, with the first antenna located at a corner and in a different position from the second antenna. The first antenna can serve as a phase-scanning antenna for both the first and second communication networks. By switching the switching circuit 10, the antenna pattern of the first antenna can be compensated for in different communication networks.

[0056] Taking the first frequency band as the Wi-Fi band and the second frequency band as the key 5G band N41 / 78 as an example, in related technologies, the key 5G frequency band N41 / 78 typically only has four antennas, resulting in blind spots in antenna pattern coverage. (Example: N41 four-way pattern) Figure 4 As shown, for ease of comparison, Figure 4 The four antennas in the diagram are positioned the same as the four third antennas in this embodiment. There is a certain blind spot on the right side of the diagram. Furthermore, some electronic devices do not support Wi-Fi MIMO and only have one antenna for 2.4G, such as... Figure 5 As shown, blind spots also exist in the radiation pattern coverage.

[0057] In this embodiment, in addition to the second and third antennas, the antenna group also includes a first antenna. The first antenna can function as a phase-scanning antenna for 2.4G Wi-Fi, as well as for N41 and N78, thus meeting the phase-scanning requirements of the three major 5G frequency bands operated in China. Through the switching circuit 10, phase scanning of N41, N78, and Wi-Fi 2.4 is simultaneously achieved in a very small space, compared to... Figure 4 and Figure 5 The radiation pattern of the related technologies shown in the embodiment demonstrates significant benefits from radiation pattern compensation, such as... Figure 6 The simulation pattern of the cellular network in this embodiment is shown below. Figure 7 As can be seen from the simulation pattern of the WIFI network in this embodiment, regardless of whether it is the N41 frequency band or the 2.4G WIFI frequency band, the pattern of the first antenna can effectively complement the pattern of the previous antenna.

[0058] For example, the antenna array can also be configured with other antennas to support operation in other frequency bands, for example, such as... Figure 8As shown, the antenna array may also include several fourth antennas (two fourth antennas are shown in the figure as an example, ANT01 and ANT02 in the figure), used to support operation in the low frequency band; and a fifth antenna (two fourth antennas are shown in the figure as an example, ANT03 and ANT04 in the figure), used to support operation in the ultra-high frequency band, satellite positioning band (e.g., L1 band), etc. These will not be described in detail in this embodiment.

[0059] For example, the middle board can be used to mount electronic components such as batteries, motherboards, and camera modules of electronic devices. The motherboard can integrate electronic components such as processors, storage units, power management modules, and baseband chips of electronic devices. The motherboard can be a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit), and the metal ground plane on the motherboard can provide ground terminals to each antenna. The aforementioned first radio frequency circuit and second radio frequency circuit can be set on the circuit board, and controllers that can control the operation of electronic devices can also be integrated.

[0060] The following are some optional examples to further explain the switching method of switching circuit 10:

[0061] In one embodiment, such as Figure 9 As shown, the second radio frequency circuit 30 has multiple antenna terminals (four antenna terminals are shown as an example in the figure), and one antenna terminal is connected to the switching circuit 10; the switching circuit 10 includes: a first switching unit 110, a second switching unit 120 and a third switching unit 130.

[0062] In this circuit, the first terminal of the first switching unit 110 is connected to the second radio frequency circuit 30, and the two second terminals of the first switching unit 110 are respectively connected to a third antenna and a first terminal of the third switching unit 130. The first terminal of the second switching unit 120 is connected to the first radio frequency circuit 20, and the two second terminals of the second switching unit 120 are respectively connected to the other first terminal of the third switching unit 130 and the second antenna. The second terminal of the third switch is connected to the first antenna. For example, the first switching unit 110, the second switching unit 120, and the third switching unit 130 can each be a single-pole double-throw switch (SPDT), which switches the connection relationship between the antenna and each radio frequency circuit by switching different port connection states.

[0063] When the electronic device establishes a connection with the first communication network, the third switch connects the first antenna to the second switch unit 120, and the second switch unit 120 connects at least one of the first antenna and the second antenna to the first radio frequency circuit 20. At this time, the first antenna is switched to serve as the phase-scanned antenna of the first communication network, and the second switch unit 120 selects at least one of the first antenna and the second antenna to connect to the first radio frequency circuit 20.

[0064] In the event that the electronic device is disconnected from the first communication network, the third switching unit 130 connects the first antenna to the first switching unit 110, and the first switching unit 110 connects one of the first antenna and a third antenna (ANT6 is shown as an example in the figure) to the second radio frequency circuit 30. At this time, the first antenna switches to function as the phase-scanning antenna of the second communication network, and the first switching unit 110 selects one of the first antenna and the third antenna to connect to the second radio frequency circuit 30. When the remaining antenna terminals in the second radio frequency circuit 30 can be connected to other third antennas, this antenna can work with other third antennas to support the multi-antenna transmission and reception function of the second frequency band signal, for example, supporting transmission and 4*4 MIMO reception.

[0065] This embodiment uses the first switching unit 110, the second switching unit 120 and the third switching unit 130 to realize the switching between different antennas of the first radio frequency circuit 20 and the second radio frequency circuit 30, so that the electronic device can achieve antenna pattern complementarity, improve the transmission and reception quality of the electronic device and increase revenue; at the same time, it reduces the number of high-cost extractors required when two different network signals reuse the first antenna, thus reducing costs.

[0066] In one embodiment, such as Figure 10 As shown, there are multiple second radio frequency circuits 30 and multiple first switching units 110 (two are shown as an example in the figure). Each second radio frequency circuit 30 is connected to a corresponding first switching unit 110. The multiple second radio frequency circuits 30 support multiple sub-bands of the second frequency band. The multiple sub-bands can be, for example, any sub-band of the intermediate frequency band, high frequency band, and ultra-high frequency band. Further, for example, one of the second radio frequency circuits 30 supports the N41 band, and another second radio frequency circuit 30 supports the N78 band.

[0067] The switching circuit 10 also includes a first combiner 121 and a second combiner 122.

[0068] The first combiner 121 has multiple input terminals that are respectively connected to a first terminal of multiple first switching units 110. The output terminal of the first combiner 121 is connected to a third antenna. When the first switching unit 110 is turned on to the third antenna, the first combiner 121 can combine the second frequency band signals from multiple second radio frequency circuits 30 and output them to the third antenna for transmission through the third antenna. This allows multiple second radio frequency circuits 30 to reuse the third antenna, reducing the number of antennas.

[0069] The second combiner 122 has multiple input terminals that are respectively connected to the other first terminal of multiple first switching units 110. The output terminal of the second combiner 122 is connected to the third switching unit 130. When the first switching unit 110 is turned on to the third switching unit 130, the second combiner 122 can support the combination of second frequency band signals from multiple second radio frequency circuits 30 and output them to the first antenna for transmission through the first antenna. This allows multiple second radio frequency circuits 30 to reuse the first antenna, reducing the number of antennas.

[0070] It is understood that the first combiner 121 and the second combiner 122 in this embodiment are for combining multiple identical network signals, which is less expensive than combiners that combine signals from different communication networks. At the same time, the first combiner 121 and the second combiner 122 in this embodiment are for combining multiple signals from different sub-frequency bands, which is less expensive than combiners that combine signals from adjacent frequency bands, such as 2.4G WIFI and N41 signals.

[0071] In one embodiment, please continue to refer to Figure 10 When multiple second radio frequency circuits 30 also reuse other third antennas, the electronic device also includes other combiners (such as... Figure 10 The third and fourth combiners in the circuit are used to enable the multiplexing of antennas among multiple second radio frequency circuits 30, thereby further reducing costs.

[0072] In one embodiment, such as Figure 11 As shown, the second radio frequency circuit 30 has multiple antenna terminals (four antenna terminals are shown as an example in the figure), and the multiple antenna terminals are connected to the switching circuit 10; the switching circuit 10 includes: a fourth switching unit 131, a fifth switching unit 132, a sixth switching unit 133 and a seventh switching unit 134.

[0073] In this circuit, multiple first terminals of the fourth switching unit 131 are connected to the second radio frequency circuit 30; a portion of the second terminals of the fourth switching unit 131 are connected to a portion of the third antenna; the remaining second terminal of the fourth switching unit 131 is connected to the first terminal of the fifth switching unit 132; the two second terminals of the fifth switching unit 132 are respectively connected to a third antenna and a first terminal of the seventh switching unit 134; the first terminal of the sixth switching unit 133 is connected to the first radio frequency circuit 20; the two second terminals of the sixth switching unit 133 are respectively connected to the other first terminal of the seventh switching unit 134 and a second antenna; and the second terminal of the seventh switching unit 134 is connected to the first antenna. For example, the fourth switching unit 131 can be a 4P4T switch, and the fifth switching unit 132, the sixth switching unit 133, and the seventh switching unit 134 can each be a single-pole double-throw switch (SPDT). By switching different port connection states, the connection relationship between the antenna and each radio frequency circuit can be switched.

[0074] When the electronic device establishes a connection with the first communication network, the seventh switching unit 134 connects the first antenna to the sixth switching unit 133, and the sixth switching unit 133 connects at least one of the first antenna and the second antenna to the first radio frequency circuit 20. At this time, the first antenna is switched to serve as the phase-scanning antenna of the first communication network, and the sixth switching unit 133 selects at least one of the first antenna and the second antenna to connect to the first radio frequency circuit 20.

[0075] When the electronic device is disconnected from the first communication network, the seventh switch unit 134 connects the first antenna to the fifth switch unit 132. The fourth switch unit 131 and the fifth switch unit 132 jointly connect the first antenna and four of the multiple third antennas to the second radio frequency circuit 30. At this time, the first antenna switches to function as the phase-scanning antenna of the second communication network. The fifth switch unit 132 selects one of the first antennas and three third antennas and connects it to the fourth switch unit 131. The fourth switch selects one or more of the target antenna and the other three antennas for transmitting and receiving signals in the second frequency band. When the fourth switch unit 131 connects the four antennas to the second radio frequency circuit 30, the target antenna and the other three antennas jointly support the multi-antenna transmission and reception function of the second frequency band signal, for example, supporting transmission and 4*4 MIMO reception.

[0076] This embodiment uses the fourth switch unit 131, the fifth switch unit 132, the sixth switch unit 133, and the seventh switch unit 134 to achieve switching between different antennas of the first radio frequency circuit 20 and the second radio frequency circuit 30, enabling the electronic device to achieve antenna pattern complementarity, improving the transmission and reception quality of the electronic device, and increasing revenue; at the same time, it reduces the number of high-cost extractors required when two different network signals reuse the first antenna, thus reducing costs.

[0077] In one embodiment, such as Figure 12 As shown, there are multiple second radio frequency circuits 30 (two are shown as an example in the figure), and multiple fourth switching units 131 and fifth switching units 132. Each second radio frequency circuit 30 is connected to one fourth switching unit 131 and one fifth switching unit 132. The multiple second radio frequency circuits 30 support multiple sub-bands of the second frequency band. The multiple sub-bands can be, for example, any sub-band of the intermediate frequency band, high frequency band, and ultra-high frequency band. Further, for example, one of the second radio frequency circuits 30 supports the N41 band, and another second radio frequency circuit 30 supports the N78 band.

[0078] The switching circuit 10 also includes a fifth combiner 141 and a sixth combiner 142. When multiple second radio frequency circuits 30 also multiplex other third antennas, the electronic equipment also includes other combiners (such as...). Figure 12 The seventh and eighth combiners in the diagram are shown in the attached figure. The connection relationship of each combiner is described in the above embodiment. They will not be repeated here.

[0079] In one embodiment, the first RF circuit 20 and the second RF circuit 30 described above may each include circuits formed by combining discrete components, such as power amplifiers (PA), low-noise amplifiers (LNA), duplexers, combiners, etc., and may also include RF front-end devices configured with multiple ports, such as L-PA Mid (LNA PowerAmplifier Modules including Duplexers, power amplifier modules with built-in low-noise amplifiers), and combinations of LFEM (Low Noise Amplifier Front-End Modules) and DiFEM (Diversity Front-end Module, integrating filters and switches), etc. This embodiment is not specifically limited here; the foregoing is merely illustrative.

[0080] In one embodiment, the electronic device further includes a control circuit for determining the connection relationship between the electronic device and the first communication network and the second communication network, and controlling the switching circuit 10 to switch the connection relationship between the first antenna, the second antenna, and at least part of the third antenna with the first radio frequency circuit 20 and the second radio frequency circuit 30, respectively.

[0081] For example, the control circuit may include a radio frequency transceiver, which uses transmit power information, network information, etc., received by the radio frequency transceiver to determine the corresponding target antenna in order to control the switching state of the switching circuit 10. The radio frequency transceiver may be configured with a control interface. The control interface includes either a MIPI (Mobile Industry Processor Interface) interface or a GPIO (General Purpose Input Output) interface. The radio frequency transceiver can send switching control signals to each switching unit of the switching circuit 10 through the MIPI interface or the GPIO interface to improve control efficiency.

[0082] For example, the control circuit may also include an AP (Application Processor) and / or a BP (Baseband Processor), which determines the corresponding target antenna based on the received transmit power information, network information, etc., and then controls the RF transceiver to output the corresponding switching control signal.

[0083] In one embodiment, the above-mentioned electronic device is described using a mobile phone 11 as an example. Figure 13 As shown, the mobile phone 11 may include a memory 21 (which optionally includes one or more computer-readable storage media), a processor 22, a peripheral device interface 23, a radio frequency system 24 (which may include the first radio frequency circuit 20, the second radio frequency circuit 30, the antenna assembly, and the radio frequency transceiver mentioned in the above embodiments), and an input / output (I / O) subsystem 26. These components optionally communicate via one or more communication buses or signal lines 29. Those skilled in the art will understand that...

Figure 13 The various components shown are implemented in hardware, software, or a combination of both, including one or more signal processing and / or application-specific integrated circuits.

[0084] Memory 21 optionally includes high-speed random access memory, and also optionally includes non-volatile memory, such as one or more disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Exemplary examples include software components stored in memory 21 such as an operating system 211, a communication module (or instruction set) 212, a global positioning system (GPS) module (or instruction set) 213, etc.

[0085] The processor 22 and other control circuits can be used to control the operation of the mobile phone 11. The processor 22 can be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio codec chips, application-specific integrated circuits, etc.

[0086] The processor 22 can be configured to implement control algorithms for controlling the use of the antenna in the mobile phone 11. The processor 22 can also issue control commands for controlling various switches in the radio frequency system 24.

[0087] I / O subsystem 26 couples input / output peripherals on mobile phone 11, such as a keypad and other input control devices, to peripheral interface 23. I / O subsystem 26 optionally includes a touchscreen, buttons, a tone generator, an accelerometer (motion sensor), an ambient light sensor and other sensors, LEDs and other status indicators, data ports, etc. For example, a user can control the operation of mobile phone 11 by supplying commands via I / O subsystem 26, and can use the output resources of I / O subsystem 26 to receive status information and other outputs from mobile phone 11. For example, a user can press button 261 to turn the phone on or off.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
