Particle Swarm Optimization for Antenna Far-Field Radiation Pattern Reconstruction

A particle swarm optimization (PSO) based algorithm applied to antenna far-field radiation pattern prediction from planar near-field samples is presented. The radiation of the antenna is modeled using equivalent magnetic currents (EMC) whose components are optimized using a global version of PSO with asynchronous updates of the swarm. An analysis of the main parameters to be tuned in PSO, along with results of near-field to far-field transformation are included
