Abstract
In this paper the optimal design for maximum sidelobe level (SLL) reduction of three-ring Concentric Circular Antenna Array (CCAA) is determined using a novel Particle Swarm Optimization (PSO) technique namely Improved Particle Swarm Optimization (IPSO) algorithm. Standard PSO is also adopted for the comparative optimization. The present text assumes non-uniformly excited and non-uniform inter-element spacing array with a design goal of maximizing SLL reduction using the above two evolutionary optimization techniques. It is shown that among all the designs, the three-ring structure containing (N1=4, N2=6, N3=8) elements proves to be the optimal design owing to the highest SLL reduction achieved by each technique. IPSO yields grand minimum SLL (-31.86dB) for the above optimal set.
