Partial Characterization of Aperture Antennas in Planar Near-Field Scanning

In the framework of the near-field antenna characterization, in some applications, it can be of interest to retrieve the Far-Field pattern just along some cuts. A Partial Characterization method is a technique able to reconstruct the pattern along the cut of interest starting from a proper set of near-field data. A Partial Characterization method has been proposed. The approach is able to determine the optimal distribution of the near-field samples needed for the characterization. In this paper the method is presented and its main characteristics analyzed. Furthermore, experimental results are reported to show the performance of the approach against real data.
