1. A switch circuit, comprising:
an antenna port; and
multiple switch branches arranged parallel to each other;
wherein
each of the switch branches comprises a first switch, a second switch and a third switch;
a first end of the antenna port is connected with an antenna;
a second end of the antenna port is electrically connected with a third end of the first switch of each of the at switch branches respectively;
a fourth end of the first switch of each of the switch branches is electrically connected with a fifth end of the second switch corresponding to each of the switch branches and a sixth end of the third switch corresponding to each of the switch branches respectively;
a seventh end of the second switch corresponding to each of the switch branches is connected with a ground terminal;
an eighth end of the third switch corresponding to each of the switch branches is electrically connected with a ninth end of a load corresponding to each of the switch branches;
a tenth end of the load is connected with the ground terminal;
a target switch branch of the switch branches is configured to, when the first switch and the third switch corresponding to the target switch branch are closed and the second switch corresponding to the target switch branch is opened, transmit a first radio frequency signal; and
the target switch branch is determined, by a wireless communication device, from the switch branches based on the first radio frequency signal.
