Side-Lobe Level Reduction of Concentric Array Antennas Using Craziness Based Particle Swarm Optimization Technique

Abstract

In the following paper the Craziness based Particle Swarm Optimization (CRPSO) scheme has been used that entitles a recent technique in electromagnetic for optimizing the problems that are caused for the array pattern synthesis of 90-element Concentric Circular Array (CCA) and Concentric Elliptical Array (CEA) of isotropic antennas that produces directive beams with utmost reduction of the Side-Lobe-Level (SLL). The paper demonstrates a newly used algorithm which is CRPSO which is used for pattern synthesis of the arranged planar array, CEA, by optimizing the amplitude with required SLL value. Simultaneously, compare with conventional PSO method and its improved version (IPSO), CRPSO is used with the intention of producing utmost SLL reduction.
