Abstract
A switch circuit design for a switchable three-beam patch array antenna comprises: a diode switch control circuit and a switch control module; wherein the switch control module is used to control the opening (ON) and closing (OFF) of the first, second, third, fourth, fifth, and sixth diode switches of the diode switch control circuit, and therefore control the transmission path of signals received by the patch array antenna that is connected to the diode switch control circuit, which is automatically switched to receive three input signals with phase differences of -90 degrees, 0 degree, and 90 degrees, and the patch array antenna can achieve three-beam switching.
