Raster Scan Multi-Frequency Near-Field Antenna Characterization

Abstract

The paper deals with the multi-frequency characterization of antennas by using Near-Field measurements collected over one optimized grid common to all the frequencies. In this way the frequency measurements are carried out with a single scan. The approach provides a drastic reduction of the number of measurement points and uses a raster scan grid to take advantage of the classical continuous scan or of the new scanning capabilities shown in [6].
