An algorithm to measure in Anechoic Chamber (AC) the antenna Phase Center (PhC) position is presented. It is based on the assumption that the PhC belongs to the geometrical symmetry axis of the antenna under test. In particular, the algorithm is able to account for the possible presence of an unknown misalignment between such axis and the rotation axis of the turntable of the AC, thus extending the two point-approach available in the literature. The method has been validated through measurements on an X-band microstrip radar antenna.

Abstract
An algorithm to measure in Anechoic Chamber (AC) the antenna Phase Center (PhC) position is presented. It is based on the assumption that the PhC belongs to the geometrical symmetry axis of the antenna under test. In particular, the algorithm is able to account for the possible presence of an unknown misalignment between such axis and the rotation axis of the turntable of the AC, thus extending the two point-approach available in the literature. The method has been validated through measurements on an X-band microstrip radar antenna.File in questo prodotto:
