This work deals with the experimental validation of a probe compensated near-field — far-field (NF-FF) transformation with plane-polar scanning, which makes possible to lower the number of needed measurements, as well as the time required for the data acquisition when dealing with quasi-planar antennas. It relies on the use of the nonredundant sampling representations of electromagnetic fields, employing an oblate ellipsoid to shape an antenna under test characterized by quasi-planar geometry. A two-dimensional optimal sampling interpolation formula allows the reconstruction of the NF data at any point on the measurement plane and, in particular, at those required by the classical NF-FF transformation with the plane-rectangular scan. Some experimental results carried out at the UNISA Antenna Characterization Lab and assessing the effectiveness of the technique are shown.

Abstract

This work deals with the experimental validation of a probe compensated near-field — far-field (NF-FF) transformation with plane-polar scanning, which makes possible to lower the number of needed measurements, as well as the time required for the data acquisition when dealing with quasi-planar antennas. It relies on the use of the nonredundant sampling representations of electromagnetic fields, employing an oblate ellipsoid to shape an antenna under test characterized by quasi-planar geometry. A two-dimensional optimal sampling interpolation formula allows the reconstruction of the NF data at any point on the measurement plane and, in particular, at those required by the classical NF-FF transformation with the plane-rectangular scan. Some experimental results carried out at the UNISA Antenna Characterization Lab and assessing the effectiveness of the technique are shown.
