[0025] In the embodiments of the present application, the words "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying order. For example, the first application, the second application, etc. are used to distinguish different applications, rather than to describe a specific order of applications. The features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] Usually, users can use the satellite communication function of electronic devices for emergency communication when they are in areas that are not covered by the communication network. In the scenario where electronic devices use satellite communication, in order to avoid the human head affecting the antenna during voice calls, users need to establish a connection with the electronic device through a Bluetooth headset before using the Bluetooth headset for voice communication. Therefore, how to ensure the communication performance of electronic devices when satellite communication and Bluetooth coexist has become a problem that needs to be solved urgently.

[0032] Exemplarily, the RF module 10 is installed in the inner cavity of the whole machine. The RF module 10 can be electrically connected to the frame 40. The RF module 10 can be used to process the communication signal and transmit it to the antenna to be transmitted via the antenna, or to process the communication signal received by the antenna and transmit it to other modules for subsequent processing to realize the communication function of the electronic device 100. The RF module 10 may include structures such as chips and circuit boards. Understandably, the RF module 10 can also be electrically connected to antennas of other structures to realize the communication function of the electronic device 100.

[0033] The display screen 20 is used to display images, and the display screen 20 may also integrate a touch function to achieve human-computer interaction. The back cover 30 is used to protect the internal structure of the electronic device 100, and the back cover 30 may be made of metal material, non-metal material, or a metal and non-metal composite material.

[0040] It can be understood that in this embodiment, the first to eighth gaps mentioned above all pass through and separate the frame 40. The first to eighth gaps together divide a plurality of metal segments from the frame 40. Every two metal segments are separated by a gap. The plurality of metal segments can form a plurality of antennas of the electronic device 100 for transmitting and / or receiving communication signals. Different metal segments can form different antennas. One antenna can cover one or more communication frequency bands.

The metal segment between the second slot 402 and the fifth slot 405 is the antenna 43, and the antenna 43 is the top cellular antenna of the electronic device 100. The metal segment between the third slot 403 and the fourth slot 404 is the antenna 45. The antenna 45 is the side cellular antenna of the electronic device 100. The metal segment between the fifth slot 405 and the sixth slot 406 is the antenna 46, and the antenna 46 is the side cellular antenna of the electronic device 100. The metal segment between the seventh slot 407 and the eighth slot 408 is the antenna 44, and the antenna 44 is the bottom cellular antenna of the electronic device 100.

[0043] In other words, the antenna 41 of the present application is set at the top of the frame 40, the second antenna is set at the upper left corner of the frame 40, the antenna 44 is set at the lower right corner of the frame 40, and the antenna 45 and the antenna 46 are set on the side of the frame 40.

[0044] Among them, satellite communication refers to the communication between two or more ground stations using artificial satellites as relay stations to forward or reflect radio signals.

[0045] WiFi and Bluetooth are wireless networking technologies that enable wireless communication within a certain range.

[0046] Cellular mobile communication is a wireless communication technology that uses a mesh structure to achieve wireless communication over a large area. Exemplarily, cellular mobile communication can use a variety of network types, such as: global system for mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), long term evolution (LTE), etc. Cellular mobile communication can also use a variety of communication frequency bands, such as: N41, N78, N79, etc. In an embodiment of the present application, the electronic device 100 can use N41 as the working frequency band of cellular mobile communication.

[0047] Exemplarily, in the present application, antenna 41 is a satellite communication antenna, and electronic device 100 can send and receive satellite communication signals through antenna 41. Antenna 42 is a Bluetooth antenna, and electronic device 100 can send and receive Bluetooth signals through antenna 42. Antenna 43, antenna 45, antenna 46, and antenna 44 are cellular antennas.

[0050] See also Figure 3 , Figure 3 1 is a partial structural diagram of an electronic device 100 provided by an embodiment of the present application. For example, the antenna 42 may include a feed point 421, and the antenna 43 may include a feed point 431. The feed point 421 may be arranged on the antenna 42, and the feed point 431 may be arranged on the antenna 43.

[0051] For example, Figure 3 As shown, the feed point 421 can be connected to the system ground via the switch S1 , and the feed point 431 can be connected to the system ground via the switch S2 .

[0052] It can be understood that in a possible application scenario, when antenna 41 is working, antenna 42 and antenna 43 are in a short-circuit state, that is, antenna 42 and antenna 43 are not working. For example, when antenna 41 (i.e., satellite communication antenna) is working, switch S1 and switch S2 are in a conducting state, so that antenna 42 (i.e., Bluetooth antenna) is short-circuited to ground, and antenna 43 (i.e., cellular antenna) is short-circuited to ground, so that current is not excessively coupled to antenna 42 and antenna 43, thereby ensuring the gain of the satellite communication antenna.

[0053] In this embodiment, Figure 3 As shown, the switch S3 and the switch S4 can be used to adjust the operating frequency of the antenna 41. For example, the switch S3 is used to optimize the performance of the antenna 41 at the transmitting frequency point. The switch S4 is used to optimize the performance of the antenna 41 at the receiving frequency point.

[0075] like Figure 4 As shown, the switches 23, 24 and 25 can be divided into two states, namely, a through state and a cross state.

[0077] See also Figure 5 , Figure 5 It is a partial structural diagram of an electronic device 100 provided in one embodiment of the present application.

[0078] and Figure 4 The difference between the electronic device 100 shown in the embodiment is that Figure 5 As shown, in this embodiment, the RF module 10 also includes a switch 36 and a switch 37 .

[0079] The switch 36 includes a first connection point 361, a second connection point 362, and a third connection point 363. The switch 37 includes a first connection point 371, a second connection point 372, and a third connection point 373.

[0080] In this embodiment, the first connection point 361 of the switch 36 is connected to the second movable contact 252 of the switch 25, the second connection point 362 of the switch 36 is connected to the filter 262, and the third connection point 363 of the switch 36 is connected to the third connection point 373 of the switch 37. The first connection point 371 of the switch 37 is connected to the filter 271, and the second connection point 372 of the switch 37 is connected to the antenna 42.

[0081] In this embodiment, the switch 36 and the switch 37 are both single-pole double-throw switches. The electronic device 100 may further include a control module 60. Exemplarily, the control module 60 may be a control chip in the electronic device 100.

[0082] The switch 37 can connect the Bluetooth module 13 to the antenna 42 or the switch 36. The switch 36 can connect the antenna 44 to the cellular module 12 or the switch 37.

[0083] Optionally, the switch 37 can connect the Bluetooth module 13 to the switch 36 when the satellite communication module 11 is working, and the switch 36 can connect the antenna 44 to the switch 37 when the satellite communication module 11 is working. With such a design, when the satellite communication module 11 is working, the Bluetooth module 13 can be connected to the antenna 44 through the switch 37 and the switch 36, and then the Bluetooth signal can be sent and received through the antenna 44.

[0084] Optionally, the switch 37 can also connect the Bluetooth module 13 to the antenna 42 when the satellite communication module 11 is not working, and the switch 36 can also connect the antenna 44 to the cellular module 12 when the satellite communication module 11 is not working. With such a design, when the satellite communication module 11 is not working, the Bluetooth module 13 can be connected to the antenna 42 through the switch 37, and then the Bluetooth signal can be sent and received through the antenna 42. The Bluetooth module 13 can also be connected to the antenna 44 or the antenna 45 through the switch 37 and the switch 36. The cellular module 12 can receive and send cellular signals through the antenna 44.

[0085] In a specific implementation process, the control module 60 can be connected to the switch 36 and the switch 37, that is, the control module 60 can control the states of the switch 36 and the switch 37. For example, the control module 60 can control the first connection point 361 of the switch 36 to be connected to the second connection point 362 or the first connection point 361 to be connected to the third connection point 363. The control module 60 can also control the first connection point 371 of the switch 37 to be connected to the second connection point 372 or the first connection point 371 to be connected to the third connection point 373.

[0086] The present application sets the switch 36 between the receiving end RX4 of the cellular module 12 and the switch 25, so as to minimize the insertion loss of Bluetooth and cellular N41, thereby minimizing the impact on the radio frequency performance.

[0087] It can be understood that the Bluetooth antenna and the cellular antenna do not affect each other and can work independently. In order to achieve wireless performance for communicating with satellites, the satellite communication antenna needs to occupy the entire top space of the frame 40. Therefore, when antenna 41 is working, antenna 42 and antenna 43 are in a closed state, resulting in Bluetooth being unavailable. It can be seen that in a scenario, for example, when a user uses the satellite communication function of the electronic device 100 to communicate and needs to use the Bluetooth scenario, the electronic device 100 of the present application can realize Bluetooth communication by reusing the antenna 44 at the bottom of the frame, and the isolation between antenna 41 and antenna 44 is the highest, and the coexistence of satellite communication and Bluetooth can also be avoided. Interference. In addition, in order to avoid that the current will not be excessively coupled to antenna 42 and antenna 43, antenna 42 and antenna 43 are in a short-circuit state, which can ensure the gain of the first antenna 41.

[0088] In the scenario where the satellite communication module 11 is working, the modem 70 is in a dormant state, that is, the states of the switches 23, 24, and 25 are controlled by the control module 60. The control module 60 controls the first connection point 371 of the switch 37 to be connected to the third connection point 373, and the first connection point 361 of the switch 36 to be connected to the third connection point 363, so as to switch the Bluetooth channel to the switch 25. The control module 60 also controls the switch 25 to maintain a straight-through state, so that the Bluetooth module 13 is connected to the antenna 44 at the bottom of the frame, and the Bluetooth module 13 can realize the transmission of Bluetooth signals through the antenna 44. The control module 60 also controls the antenna 42 and the antenna 43 to be grounded, so as to ensure the gain of the antenna 41. It can be understood that in other possible implementations, in the scenario where the satellite communication is working, the control module 60 can also control the switch 25 to be in a cross state, so that the Bluetooth module 13 is connected to the antenna 45 located on the side of the frame, and the Bluetooth module 13 can also realize the transmission of Bluetooth signals through the antenna 45. In other words, antenna 41 and antenna 42 do not work at the same time, and antenna 41 and antenna 44 can work at the same time. In another optional implementation, antenna 41 and antenna 45 work at the same time, or antenna 41 and antenna 46 work at the same time.

[0089] In the scenario where the satellite communication module 11 is not working, the control module 60 controls the first connection point 371 of the switch 37 to be connected to the second connection point 372, controls the first connection point 361 of the switch 36 to be connected to the second connection point 362, and releases the switch 25. The control module 60 releases the control of the antenna 42 and the antenna 43, that is, the antenna 42 and the antenna 43 are not grounded to maintain the original high gain of the RF module. The modem 70 can maintain the original control state, that is, the state of the switch 23, the switch 24, and the switch 25 is controlled by the modem 70.

[0090] See also Figure 6 , Figure 6 It is a partial structural diagram of an electronic device 100 provided in one embodiment of the present application.

[0091] and Figure 5 The difference between the electronic device 100 shown in the embodiment is that Figure 6 As shown, in this embodiment, the RF module 10 further includes a switch 38. The switch 38 may be a three-pole three-throw switch.

[0092] Compared to Figure 5 In the embodiment shown, the eighth switch 39 is used to replace the switch 25 and the switch 36. Exemplarily, the switch 38 includes a first moving contact 381, a second moving contact 382, ​​a third moving contact 383, a first stationary contact 384, a second stationary contact 385 and a third stationary contact 386.

[0093] The first moving contact 381 of the switch 38 is connected to the second static contact 244 of the switch 24, the second moving contact 382 of the switch 38 is connected to the filter 262, and the third moving contact 383 of the switch 38 is connected to the third connection point 373 of the switch 37. The first static contact 384 of the switch 38 is connected to the antenna 45, and the second static contact 385 of the switch 38 is connected to the antenna 44. In this embodiment, the second static contact 385 of the switch 38 can be used as the first connection point of the switch 38, the second moving contact 382 of the switch 38 can be used as the second connection point of the switch 38, and the third moving contact 383 of the switch 38 can be used as the third connection point of the switch 38. When the satellite communication module 11 is working, the first connection point 371 of the first switch 37 is connected to the third connection point 373 of the switch 37, and the second static contact 385 of the switch 38 is connected to the third moving contact 383 of the switch 38. When the satellite communication module 11 is not working, the first connection point 371 of the switch 37 is connected to the second connection point 372 of the switch 37 , and the second static contact 385 of the switch 38 is connected to the second moving contact 382 of the switch 38 .

[0094] Understandably, compared to Figure 5 In the embodiment shown, the switch 25 and the switch 36 are replaced with a three-pole three-throw switch, and the antenna 44 at the bottom of the frame can also be reused for Bluetooth communication without affecting the front-end insertion loss of the cellular. Based on such a design, the RF module and the electronic device of the present application can realize antenna reuse and reduce the difficulty of antenna design.

[0095] By adopting the RF module and electronic device of the present application, the cellular antenna at the bottom of the frame is reused as a Bluetooth antenna, so that the isolation between the satellite communication antenna and the Bluetooth antenna is high and the coexistence interference is small, which can ensure that the performance of the electronic device under satellite communication and Bluetooth coexistence meets the user's requirements and improve the user experience.

[0096] See also Figure 7 , Figure 7 It is a partial structural diagram of an electronic device 100 provided in one embodiment of the present application.

[0097] and Figure 5 The difference between the electronic device 100 shown in the embodiment is that Figure 7 As shown, in this embodiment, the switch 36 is connected between the receiving end RX3 of the cellular module 12 and the switch 24 .

[0098] Specifically, the first connection point 361 of the switch 36 is connected to the second movable contact 242 of the switch 24. The first connection point 362 of the switch 36 is connected to the third connection point 373 of the switch. The third connection point 363 of the switch 36 is connected to the receiving end RX3 of the cellular module 12 through the cellular receiving path 19. It can be understood that in this embodiment, the second movable contact 252 of the switch 25 is connected to the receiving end RX4 of the cellular module 12 through the cellular receiving path 26.

[0099] In this embodiment, in the scenario where the satellite communication module 11 is working, the control module 60 controls the first connection point 371 of the switch 37 to be connected to the third connection point 373, and controls the first connection point 361 of the switch 36 to be connected to the third connection point 363, so as to switch the Bluetooth channel to the switch 24. Therefore, the control module 60 controls the state of the switch 24, for example, the control module 60 controls the second moving contact 242 of the switch 24 to be connected to the first static contact 243, so that the Bluetooth module 13 can be connected to the antenna 46, and then the Bluetooth signal is received and sent through the antenna 46.

[0100] In the scenario where the satellite communication module 11 is not working, the control module 60 controls the first connection point 371 of the switch 37 to be connected to the second connection point 372, and controls the first connection point 361 of the switch 36 to be connected to the second connection point 362. The control module 60 releases the control of the antenna 42 and the antenna 43, that is, the antenna 42 and the antenna 43 are not grounded to maintain the original high gain of the RF module. The modem 70 maintains the original control state, that is, the state of the switch 23, the switch 24, and the switch 25 is controlled by the modem 70.

[0101] See also Figure 8 , Figure 8 1 is a flow chart of a control method of a radio frequency module provided by an embodiment of the present application. The control method of the radio frequency module may include the following steps:

[0102] Step S81: receiving user control instructions.

[0103] The electronic device 100 may receive a control instruction from a user.

[0104] Step S82: Whether the satellite communication function is turned on. If the satellite communication function is turned on, go to step S83, otherwise go to step S85.

[0105] Step S83: The modem enters a sleep state.

[0106] by Figure 5The electronic device 100 shown in the embodiment is used as an example for illustration, and the electronic device 100 turns on the satellite communication function according to the upper user control instruction. In this scenario, the modem 70 enters a dormant state and releases the control of the switch 25. In other words, the control module 60 can control the state of the switch 25.

[0107] Step S84: The control module controls the first switch and the second switch to be connected, controls the third switch to be in a through state, and controls the second antenna and the third antenna to be short-circuited and grounded. When the electronic device 100 turns on the satellite communication function, that is, when the satellite communication module 11 is working, the control module 60 controls the switch 36 and the switch 37 to be connected, controls the switch 25 to be in a through state, and controls the antenna 42 and the antenna 43 to be short-circuited and grounded.

[0108] For example, the control module 60 will control the antenna 42 and the antenna 43 to be grounded to prevent the current from being excessively coupled to the antenna 42 and the antenna 43, thereby ensuring the gain of the antenna 41. The control module 60 controls the first connection point 371 of the switch 37 to be connected to the third connection point 373, and the first connection point 361 of the switch 36 to be connected to the third connection point 363. The control module 60 also controls the switch 25 to remain in a straight-through state, thereby connecting the Bluetooth module 13 to the antenna 44 at the bottom of the frame, so that the Bluetooth module 13 can transmit the Bluetooth signal through the antenna 44. In other words, the antenna 41 and the antenna 42 do not work at the same time, and the antenna 41 and the antenna 44 can work at the same time. In another optional implementation, the antenna 41 and the antenna 45 work at the same time, or the antenna 41 and the antenna 46 work at the same time.

[0109] The present application reuses the antenna 44 located at the bottom of the frame as a Bluetooth antenna, thereby achieving high isolation between the satellite communication antenna and the Bluetooth antenna and low coexistence interference, thereby ensuring the communication performance of the electronic device 100 when satellite communication and Bluetooth coexist.

[0110] Step S85: The control module controls the second switch to connect the cellular module and the third switch, controls the first switch to connect the Bluetooth module and the second antenna, releases the control of the third switch to the modem, and controls the second antenna and the third antenna to enter working state.

[0111] When the satellite communication function of the electronic device 100 is turned off, that is, the satellite communication module 11 is not working, the control module 60 controls the first connection point 361 of the switch 36 to be connected to the second connection point 362 to connect the receiving end RX4 of the cellular module 12 to the switch 25, and controls the first connection point 371 of the switch 37 to be connected to the second connection point 372 to connect the transmitting and receiving end TRX of the Bluetooth module 13 to the antenna 42. The control module 60 will also release the control right of the switch 25 to the modem 70.

[0112] Step S86: the modem controls the third switch, the fourth switch and the fifth switch.

[0113] In this embodiment, the modem 70 controls the switches 23, 24 and 25 according to the default scheduling scheme.

[0114] Among them, switch 21, switch 22, switch 36 and switch 37 are single-pole double-throw switches, and switch 23, switch 24 and switch 25 are double-pole double-throw switches.

[0115] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application. Therefore, as long as they are within the scope of the essence and spirit of the present application, appropriate changes and modifications made to the above embodiments should fall within the scope of protection claimed in the present application.
