Development of high performance antenna depends on a high-precision test system. Antenna test system includes servo system, test equipment and monitoring system. The merit of the servo system affects the accuracy of the anechoic chamber antenna test directly. Thus,the design of the servo system is significant. Put forward an antenna pattern test servo system which controls the rotation of the mo-tor through the ARM processor,in order to record the antenna test data while adjusting the measured antenna attitude. This servo system can receive bi-far-field measurements automatically and reduce the difficulty of testing. By means of spectrum analyzer,the servo system can precisely measure antenna pattern,the beam width,the side lobe width,antenna gain and other parameters,which has a small measure-ment error,strong anti-interference ability and is capable of high sensitivity measurements. As the test of microwave anechoic chamber antenna technology is widely applied to industrial projects,this rotating servo system has very high practical value.
