A phase retrieval method based on an iterativeFourier technique is tested together with the application of probecorrection of the retrieved results; to the best of our knowledgethis the first experimental demonstration of probe correction inphaseless near-field antenna measurements. The obtained resultsindicate good agreement with a measured reference patternwithin the region of validity when the probe correction isapplied after performing the phase retrieval from a pair ofuncorrected probe signals. Additional improvements are obtainedby introducing spatial filtering at the aperture of the antennaunder test.
