Abstract: An electronic device includes a first circuit board, a second circuit board stacked with the first circuit board, and a connection plate connected between the first circuit board and the second circuit board. The connection plate includes a signal transmission part and at least one ground part at a spacing to the signal transmission part. The ground part can be used as a reference ground for a signal transmitted by the signal transmission part, so that the characteristic impedance of the signal transmission part is controllable, and the signal transmitted by the signal transmission part has strong continuity, thereby maintaining good matching performance and reducing an insertion loss caused by characteristic impedance mismatch.

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.
