Abstract
An antenna switching circuit includes: a first switching circuit and a second switching circuit. The first switching circuit is electrically connected with at least two first radio frequency paths and at least two first antennas, respectively. In a first state, one of the first radio frequency paths is connected with one of the first antennas, and an operating band of one of the first radio frequency path is a first frequency band; the second switching circuit is electrically connected with at least two second radio frequency paths and at least two second antennas, respectively. In a second state, one of the second radio frequency paths is connected with one of the second antennas, and an operating band of one of the second radio frequency band is a second frequency band. The first frequency band is lower than the second frequency band.
