See tables 1 and 2. Wherein, the M terminal is the second terminal 114-2 of the first single-pole double-throw switch 114, the X terminal is the second terminal 115-2 of the second single-pole double-throw switch 115, the N terminal is the third terminal 114-3 of the first single-pole double-throw switch 114, and the Y terminal is the third terminal 115-3 of the second single-pole double-throw switch 115. As can be seen from tables 1 and 2, in the first operation mode, the first end 114-1 and the second end 114-2 of the first single-pole double-throw switch 114 are connected, so that the rf transceiver component 111 forms a complete circuit with the first antenna component 112 through the first single-pole double-throw switch 114, and performs operations of transmitting a first signal and receiving a second signal. The first end 115-1 and the second end 115-2 of the second single-pole double-throw switch 115 are communicated, so that the radio frequency transceiving component 111 forms a complete circuit with the second antenna component 113 through the second single-pole double-throw switch 115 to perform the operation of receiving the second signal.
In the second operation mode, the first end 114-1 and the third end 114-3 of the first single-pole double-throw switch 114 are communicated, the first end 114-2 and the third end 114-3 of the second single-pole double-throw switch 115 are communicated, and the third end 114-3 of the first single-pole double-throw switch 114 and the third end 115-3 of the second single-pole double-throw switch 115 are electrically connected, so that the radio frequency transceiver forms a passage with the first antenna assembly 112 and the second antenna assembly 113 through the first single-pole double-throw switch 114 and the second single-pole double-throw switch 115 to perform the operation of transmitting the first signal and receiving the second signal.
Correspondingly, referring to fig. 3, in response to the operation mode of the antenna module 110 being the first operation mode, the rf transceiver component 111 generates the first signal and transmits the first signal to the first spdt switch 114, the first spdt switch 114 is configured to transmit the first signal to the first antenna component 112, and the first antenna component 112 is configured to radiate the first signal;
the first antenna assembly 112 is further configured to receive the second signal radiated by other electronic devices, and transmit the second signal to the first single-pole double-throw switch 114, and the first single-pole double-throw switch 114 is further configured to transmit the second signal to the rf transceiver assembly 111;
the second antenna module 113 is configured to receive the second signal radiated by other electronic devices and transmit the second signal to the second single-pole double-throw switch 115, and the second single-pole double-throw switch 115 is configured to transmit the second signal to the rf transceiver module 111.
In the embodiment of the present application, the process of the antenna module 110 radiating a signal and the process of receiving a signal are decoupled. That is, the process of receiving and transmitting signals by the antenna module 110 is performed in different time slots. The uplink and downlink of the antenna do not work simultaneously. For example, when the process of transmitting the first signal is switched to the second antenna assembly 113, the second antenna assembly 113 does not perform the signal reception function; accordingly, when the second antenna module 113 receives the second signal, no signal transmission is performed. For example, the antenna module 110 is applied to a Time Division duplex (TDD _ NR) signal in a fifth generation communication system.
In some embodiments, the antenna module 110 controls the switching between the first antenna element 112 and the second antenna element 113 through the control element 116. Correspondingly, referring to fig. 4, the antenna module 110 further includes a control component 116; the control component 116 is electrically connected to the first single-pole double-throw switch 114 and the second single-pole double-throw switch 115 respectively; the control component 116 is configured to determine a target operating mode matching the current signal quality according to the current signal quality, generate a mode switching instruction in response to that the current operating mode of the antenna module 110 is different from the target operating mode, and send the mode switching instruction to the first single-pole double-throw switch 114 and the second single-pole double-throw switch 115; the first single-pole double-throw switch 114 and the second single-pole double-throw switch 115 are further configured to receive the mode switching instruction, and change an electrical connection mode of a port according to the mode switching instruction.
In some embodiments, the control component 116 determines whether a mode switch instruction is currently generated by detecting the signal quality of the current environment. The signal quality includes signal strength, signal fading degree, dominant frequency bandwidth, dominant frequency direction, etc. In some embodiments, the control component 116 comprises a signal detection unit by which the signal quality of the environment in which the terminal is located is detected. In response to the signal quality not matching the current operating mode of the antenna module 110, a mode switch command is generated. For example, the signal detection unit collects a signal in the current environment, analyzes the dominant frequency direction in the signal, determines an antenna assembly of which the dominant frequency direction is matched with the dominant frequency direction of the current environment from the two antenna assemblies according to the dominant frequency direction, determines whether the current working mode is the mode of working with the antenna assembly, and generates a mode switching instruction if the current working mode is not the mode of working with the antenna assembly. Wherein, matching refers to that the dominant frequency direction of the antenna component is the same as or similar to the dominant frequency direction in the current environment.
It should be noted that the antenna module 110 can also determine the working mode of the antenna module 110 first, and then determine the signal quality corresponding to the antenna element corresponding to the working mode, so as to generate the mode switching instruction according to whether the signal quality and the signal quality in the current environment are matched with the signal quality of the antenna element, if not.
In some embodiments, antenna components in the terminal may be obscured due to the user's posture while using the terminal. Therefore, the antenna module 110 can also determine whether to generate the mode switching command by detecting whether the antenna element is blocked. Accordingly, the control component 116 includes detection units respectively disposed at the corresponding positions of the first antenna component 112 and the second antenna component 113. The detection unit is used for detecting whether the antenna assembly is shielded or not, determining whether the shielded antenna assembly is the antenna assembly used in the current working mode or not, and if so, generating a mode switching instruction.
It should be noted that the antenna module 110 can also determine the antenna component corresponding to the current operating mode, then determine whether the antenna component is blocked by the detection unit, and generate the mode switching instruction in response to the antenna component being blocked.
It should be noted that, the number of the control elements 116 is set according to the requirement, for example, if the number of the control elements 116 is 1, the control elements 116 are electrically connected to the first antenna element 112 and the second antenna element 113 respectively; the number of the control elements 116 is two, and the control elements 116 include a first control element and a second control element, so that the first control element 116 is electrically connected to the first antenna element 112, and the second control element 116 is electrically connected to the second antenna element 113.
Wherein, the mode switching command carries the connection status of the first spdt switch 114 and the second spdt switch 115; for instructing to switch the operation mode of the antenna module 110 from the first operation mode to the second operation mode, or for instructing to switch the operation mode of the antenna module 110 from the second operation mode to the first operation mode.
Correspondingly, in response to the first operating mode being switched to the second operating mode, the first spdt 114 is configured to receive the mode switching command, and switch the electrical connection mode from the second end of the first spdt 114 to the third end of the first spdt according to the mode switching command; the second spdt 115 is configured to receive the mode switching command, and switch an electrical connection mode from the first end of the second spdt 115 to the third end of the second spdt 115 according to the mode switching command; in response to the second operating mode being switched to the first operating mode, the first spdt switch 114 is configured to receive the mode switching command, and switch the electrical connection mode from the third end of the first spdt switch 114 to the second end of the first spdt according to the mode switching command; the second spdt 115 is configured to receive the mode switching command, and switch an electrical connection mode from the third end of the second spdt 115 to the first end of the second spdt 115 according to the mode switching command.
In this implementation manner, the first single-pole double-throw switch 114 and the second single-pole double-throw switch 115 are controlled by the mode switching instruction, so that the antenna module 110 is switched between the first working mode and the second working mode, and the flexibility of the layout of the first antenna assembly 112 and the second antenna assembly 113 on the terminal motherboard is improved.
In the embodiment of the application, the working mode of the antenna module is controlled by using the two single-pole double-throw switches, and the two single-pole double-throw switches are mutually independent elements, so that the positions of the two single-pole double-throw switches can be flexibly set, the positions between antenna assemblies connected by the single-pole double-throw switches are not limited, and the layout of the antenna module on a terminal mainboard is more flexible.
