An effective probe compensated near-field – far-field (NF–FF) transformation with spherical scanning for an offset mounted long antenna, requiring a number of NF data that is minimum and equal to that needed in a centred configuration, is developed in this work, by applying the nonredundant sampling representations of the electromagnetic field and modelling the antenna under test (AUT) by a prolate ellipsoid.

Abstract

An effective probe compensated near-field – far-field (NF–FF) transformation with spherical scanning for an offset mounted long antenna, requiring a number of NF data that is minimum and equal to that needed in a centred configuration, is developed in this work, by applying the nonredundant sampling representations of the electromagnetic field and modelling the antenna under test (AUT) by a prolate ellipsoid. The interest for it arises from the fact that, for practical constraints, it could be not possible a centred mounting of the AUT on the scanning sphere centre and, for an offset mounting, the number of NF data required by the classical spherical NF–FF transformation can considerably grow due to the increase of the radius of the minimum sphere containing the AUT and centred on the scanning sphere centre.
