In the present embodiment, as shown in fig. 3, the first enhanced Type-C interface device 340 is different from the original Type-C interface device of the terminal 400 in that a first rf signal line terminal 341 is added on the basis of the existing terminal of the original Type-C interface device, and the first rf signal line terminal 341 is connected to an input end 331 of the rf switch module 330 for transmitting rf signals therebetween. In addition, a GPIO terminal 342 for detecting whether the second antenna module 320 is connected is added on the basis of the existing terminal, at this time, the terminal CPU420 includes a GPIO signal output pin 421 and a GPIO signal input pin 422, the GPIO signal output pin 421 is connected to the control terminal 333 of the radio frequency switch module 330, and the GPIO signal input pin 422 is connected to the GPIO terminal 342. In this way, the terminal CPU420 controls the rf switch module 330 through the GPIO signal to select whether to use the internal first antenna module 310 or the external second antenna module 320.

As shown in fig. 3, the rf switch module 330 in this embodiment employs a high power SP2T rf switch, which has high power and high voltage endurance to pass rf signals. The second antenna module 320 includes a second enhanced Type-C interface 321 and an antenna body 322, and the second enhanced Type-C interface 321 is connected to the antenna body 322. Corresponding to the structure of the first enhanced Type-C interface device 340, a second rf signal line terminal 3211 is added on the basis of the existing terminal of the original Type-C interface device, and the second rf signal line terminal 3211 is connected to the antenna body 322 for transmitting rf signals therebetween.
