Abstract :
Antenna measurement errors due to multi-path effects or antenna-probe interaction could be significant in low frequency spherical near-field test ranges. The manifestation of such effects can include increased gain variations in the antenna frequency response, distortions in the shape of the main beam or the sidelobes, appearance of unwanted or displaced sidelobes, and degradation of the cross-polarization performance.
