The paper presents a new approach to the radiation patternreconstruction Phone Accessories from near-field amplitude only measurement over a twoplanar scanning surfaces.This new method for antenna patternreconstruction is based on the global optimization PSO (Particle SwarmOptimization).The paper presents appropriate phaseless measurementrequirements and phase retrieval algorithm together with a briefdescription of the particle swarm optimization method.
In order toexamine the methodologies developed in this paper, phaselessmeasurement results for two different antennas are presented Chargers andcompared to results obtained by a complex measurement (amplitude andphase).
