To locate or to measure antenna with high precision,the error of antenna phase center is the main error source,so it is necessary to locate antenna phase center accurately.In this paper,based on the measured data of an antenna phase pattern and amplitude pattern,using the least square method we can compute the antenna phase center deviation.And with the measurement accuracy less than 1mm the proposed method can accurately and conveniently measure the phase center.
