Abstract:The Rotating-element Electric field Vector(REV) method, for far field calibration of Phased Array Antenna(PAA)，was proposed in this study. First，a 4×4 two-dimensional PAA was commendably calibrated at 0° scanning angle for using REV method by HFSS. Then，a method combining maximum method was used in wide scanning angle calibration with CST，which showed good effect. At last，a test was carried out. The results indicate that the method is valid for small PPA in wide scanning angle.
