Abstract

Measurement techniques in the antenna near-field (NF) region have a significant role in the evaluation of far-field (FF) patterns. In fact, for electrically large antennas the required size of the conventional FF range becomes prohibitively large. Moreover, NF facilities provide a controlled and secure environment, and all weather capability. Among the NF-FF transformation techniques, that employing the cylindrical scanning (Fig. 1) is particularly attractive. In fact, at the cost of a moderate increase in the analytical and computational complication with respect to the planar scannings, it allows the reconstruction of the antenna complete radiation pattern save for the zones surrounding the spherical poles.
