For example, partial areas of the frame are used as the antenna radiator 1 and the antenna radiator 2, respectively, and the antenna radiator 1 and the antenna radiator 2 control their communication states by the radiator switch 4.

Each rf module may switch its transmit or receive path through its rf switch, e.g., rf switch 1. The working state of the radio frequency module is described by taking the radio frequency module for cellular communication and the radio frequency module for satellite communication as examples. When the satellite communication radio frequency module is in a non-working state, the radiator switch 4 disconnects the antenna radiator 1 from the antenna radiator 2.

For example, the transmission path is connected to a circuit, and the antenna radiator 1 and the antenna radiator 2 operate in a satellite transmission frequency band (230 MHz). The receiving path is connected to the circuit, and the antenna radiator 1 and the antenna radiator 2 operate in satellite receiving frequency band (280 MHz). The radio frequency switch 1 is used for realizing the switching of the receiving and transmitting frequency bands, thereby effectively covering the working frequency band of the satellite and realizing the satellite communication function.
