ANTENNA SWITCHING CIRCUIT, ANTENNA SWITCHING METHOD AND ELECTRONIC DEVICE

摘要

Disclosed in the embodiments of the present application are an antenna switching circuit, an antenna switching method and an electronic device. The antenna switching circuit comprises a detection device, a controller, a first antenna, a second antenna, a first switching switch and a radio frequency transceiver module. The detection device is used to detect a change in an input impedance of the first antenna and a change in an input impedance of the second antenna; the controller is used to compare the change in the input impedance of the first antenna with the change in the input impedance of the second antenna; the first switching switch is used to turn on a first radio frequency circuit and turn off a second radio frequency circuit when the change in the input impedance of the first antenna is less than the change in the input impedance of the second antenna, the first radio frequency circuit comprising a circuit between the first antenna and the radio frequency transceiver module, the second radio frequency circuit comprising a circuit between the second antenna and the radio frequency transceiver module. The embodiments of the present application can improve antenna performance.
