Antenna switching circuit and electronic device

The utility model belongs to the technical field of electronic circuits, and particularly relates to an antenna switching circuit and an electronic device, and the antenna switching circuit comprises a control circuit, a switching circuit, a radio frequency transceiving port, a first antenna port and a second antenna port. The radio frequency transceiving port is used for connecting a radio frequency transceiving unit, the first antenna port is used for connecting an external antenna, and the second antenna port is used for connecting an internal antenna; the switching circuit selects the built-in antenna as the working antenna when the first antenna port is not connected with the antenna, and selects the external antenna as the working antenna when the first antenna port is connected with the external antenna. The internal antenna and the external antenna can be automatically switched without manual interference, misoperation during manual antenna switching is avoided, and the circuit is simple in structure
