Embodiments of the present invention provide an antenna switching apparatus, including: a switch matrix comprised of a first switch and a second switch; one terminal of the first switch is used to connect to one of a diversity antenna or a main antenna, and the other terminal of the first switch switches between the diversity link and the main link; one terminal of the second switch connects to the other one of the diversity antenna and the main antenna, the other terminal of the second switch switches between the diversity link and the main link; a control circuit module setting up a path between the main antenna and the main link, and a path between the diversity antenna and the diversity link respectively by controlling the first switch or the second switch. The present invention effectively reduces signal lines passed by the diversity signal in an antenna direct connection working mode, decreases front end insertion loss, improves performance of the mobile phone antenna and increases sensitivity of the mobile phone antenna in signal receiving. |
