Phase Retrieval Method Using a Single Planar Near-Field Measurement

Abstract

In recent years, wireless measurement methods in the near-field are developed for antenna performance evaluation. The phase measurement is difficult in near-field above the millimeter wave band, then a method to retrieve the phase using only amplitude information from a sampling plane is investigated. In this paper, we propose a method that utilizes only a single planar measurement as a faster and simpler phase retrieval method.
