Abstract
A hybridized technique based on Novel Particle Swarm Optimization (NPSO) is used to solve a design challenge for non-uniform CAAs (circular antenna arrays) single ring with the best SLL (side lobe level) and improved FNBW (first null beamwidth) as well. An optimal combination of interelement spacing and current excitation for CAA that provides an array pattern with the greatest possible reduction in SLL and FNBW is determined using this technique. It is assumed that a CAA is placed on an x-y plane. An 8-, 10-, 12-, and 20-element circular array is subjected to NPSO. The performances of side lobe level and first null beam width are analyzed after various simulation results are shown. Experimental results show a significant improvement in SLL and FNBW both as compared to the uniform case in the PSO algorithm [11] used for the same problem.
