This paper provides the experimental validation of a fast and accurate technique, which allows the reconstruction of the antenna radiation pattern from a minimum number of near-field measurements collected through a plane-polar scanning. This near-field to far-field (NFTFF) transformation technique relies on a nonredundant sampling representation of the voltage acquired by the probe, achieved by modeling the antenna with a double bowl, a very flexible model particularly suitable to deal with antennas having a quasi-planar geometry. The NF data required by the standard plane-rectangular NFTFF transformation are efficiently reconstructed from the nonredundant plane-polar ones by using an optimal sampling interpolation algorithm, thus making possible to get a considerable measurement time saving. The accuracy and practical efficacy of the described technique are assessed by experimental tests carried out at the Antenna Characterization Lab of the University of Salerno.

Abstract

This paper provides the experimental validation of a fast and accurate technique, which allows the reconstruction of the antenna radiation pattern from a minimum number of near-field measurements collected through a plane-polar scanning. This near-field to far-field (NFTFF) transformation technique relies on a nonredundant sampling representation of the voltage acquired by the probe, achieved by modeling the antenna with a double bowl, a very flexible model particularly suitable to deal with antennas having a quasi-planar geometry. The NF data required by the standard plane-rectangular NFTFF transformation are efficiently reconstructed from the nonredundant plane-polar ones by using an optimal sampling interpolation algorithm, thus making possible to get a considerable measurement time saving. The accuracy and practical efficacy of the described technique are assessed by experimental tests carried out at the Antenna Characterization Lab of the University of Salerno.
