Antenna test system

The utility model relates to the technical field of antenna testing, in particular to an antenna testing system. Comprising a multi-axis robotic arm, a grating sensing device and an upper computer connected with the grating sensing device and the multi-axis robotic arm. An antenna to be tested is positioned in front of the probe; the grating controller is connected with the upper computer; the grating transmitting end and the grating receiving end are respectively positioned on two sides between the multi-axis robotic arm and the antenna to be tested; the grating controller is used for reading state data of the grating transmitting end and the grating receiving end; the upper computer is used for reading state data of the grating transmitting end and the grating receiving end from the grating controller so as to control movement, start and stop of the multi-axis robotic arm. Therefore, according to the antenna test system provided by the utility model, the safety performance is improved, the accurate recognit
