Switchable antenna system

摘要

A switchable antenna system includes an antenna control circuit and at least one switchable antenna module coupled to the antenna control circuit. Each switchable antenna module includes a built-in antenna; a joint, for connecting an external antenna; a switching circuit, coupled to the built-in antenna and the joint, for being switched between a first mode of using the built-in antenna and a second mode of using the external antenna; and a switch, coupled to the switching circuit, for controlling the switching circuit to be switched between the first mode and the second mode.
