Errors of radiation patterns (RP) on measurement of distance and on sizes of test and probe antennas are discussed. We consider the case of circular aperture antenna with uniform field distribution. The analysis is based on time-domain (TD) physical optics (PO) method of field calculation [1-2]. We show that the optimal measurement distance with respect to acceptable small errors of RP is significantly smaller than well-known far-field distance criterion. The optimal diameter of the aperture probe antenna is the half diameter of the antenna under test.
