Claim 0:
1. An antenna switching circuit, comprising:
a first switching circuit, wherein the first switching circuit is electrically connected with at least two first radio frequency paths and at least two first antennas, respectively, and the first switching circuit comprises at least one first state, in a first state, one of the first radio frequency paths is connected with one of the first antennas, and an operating band of the first radio frequency path is a first frequency band; and
a second switching circuit, wherein the second switching circuit is electrically connected with at least two second radio frequency paths and at least two second antennas, respectively, and the second switching circuit comprises at least one second state, in a second state, one of the second radio frequency paths is connected with one of the second antennas, and an operating band of the second radio frequency band is a second frequency band; wherein
the first frequency band is lower than the second frequency band; and
a first combiner, comprising a fourth input terminal, a fifth input terminal, and a fourth output terminal, wherein the fourth input terminal is electrically connected with the first switching circuit, the fourth output terminal is electrically connected with a first target antenna, the first target antenna is one of the at least two first antennas, and the fifth input terminal is electrically connected with the second switching circuit; and the first combiner is used to combine one first radio frequency path of the at least two first radio frequency paths and one second radio frequency path of the at least two second radio frequency paths; and
the second switching circuit further comprising a third state, wherein in the third state, one of the at least two second radio frequency paths is connected with the first target antenna.
