Phase-less hemispherical near field measurement using initial phase information by PR method

Abstract

This paper presents the far field estimation using only the amplitude data on a single hemispherical surface of monopole antennas on finite sized ground plane. We propose to use the initial phase information in the Phase Retrieval (PR) method to reconstruct the phase information. The initial phase information is given by the information of measured amplitude and feeding position. By introducing this, the far field estimation can be achieved in high accuracy. This paper shows our proposed algorithm and verify it by the simulation and measurement.
