Radiation Pattern Reconstruction from the Near-Field Amplitude Measurement on Two Planes Using PSO

Blog Article

The paper presents a new 6 Piece Outdoor Seating approach to the radiation patternreconstruction 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 PATCHOULI presented andcompared to results obtained by a complex measurement (amplitude andphase).
