An efficient procedure for calibration of scanning phased antennas by means of near field planar scanner

The paper present an easy and efficient procedure for the calibration of scanning phased antennas by means of a near field planar scanner. The main steps of the procedure - modeling of the antenna architecture, near-field data transformation and phase error corrections - are described. Measurement results, obtained by the proposed procedure, are also presented. The paper concludes with some discussions about the practical application and accuracy of the algorithm.
