The paper presents a new 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 brie... https://allfixelectricales.shop/product-category/vacuum-nozzle/
