Abstract: An antenna switching circuit, electronic device and method. The switching circuit includes a radio frequency processor, a radio frequency front-end, a first switch, and an antenna system with a plurality of antennas. The radio frequency processor receives a first radio frequency signal, generates a second radio frequency signal based on a loss value of the first switch, and transmits the second radio frequency signal to the first switch. The first switch selects, from a plurality of radio frequency channels in the radio frequency front-end, a radio frequency channel coupled with the radio frequency processor, and transmits the second radio frequency signal to a radio frequency channel. The radio frequency front-end receives and processes the second radio frequency signal to generate a third radio frequency signal and transmits it to the antenna system, which outputs the third radio frequency signal.
