This article presents a thorough study of spherical probe-corrected phaseless near-field
measurements with the two-scans technique. Such technique is based on retrieving the …

The phaseless characterization of antennas enables configurations with reduced
measurement efforts as the phase acquisition is highly sensitive to numerous error sources …

This article investigates on the use of nonuniform fast Fourier transform (NUFFT) to solve
spherical near-field transformation problems. Traditional postprocessing algorithms make …

Single-cut techniques allow for fast antenna characterization by measuring and transforming
to far-field individual pattern cuts instead of the full sphere. The cut fields are expanded in a …

Phase reconstruction is in general a non-trivial problem when it comes to devices where the
reference is not accessible. A non-convex iterative optimization algorithm is proposed in this …

The paper addresses the question of efficiently sampling the near field and its intensity over
an arbitrary curved line. It aims at finding the minimum number of measurements and their …

This paper investigates on the postprocessing of spherical near-field measurements in
phaseless scenarios. Traditionally, iterative algorithms have been used to propagate …

For near-field (NF) antenna measurements where the phase cannot be measured at all or
with sufficient accuracy, it is necessary or it may be preferable to use phaseless …

Single-cut techniques allow to measure individual antenna pattern cuts in the near-field and
transform them to far-field. This avoids the full-surface scanning of conventional …

The Two Scans phase retrieval technique is based on magnitude measurements of the
antenna under test (AUT) in two different configurations and the analytical relation between …
