Comparative analysis of reduction of side lobe level for concentric elliptical and cylindrical elliptical using particle swarm optimization

This Paper describes optimal side lobe level of an elliptical cylindrical array for uniform excited isotropic antennas and non-uniform excited isotropic antennas when compared to concentric elliptical array using particle swarm optimization. Particle swarm optimization (PSO) could be a computational technique that optimizes a problem by iteratively making an attempt to enhance a candidate solution with respect to a given measure of quality. The particle swarm optimization (PSO) is used to determine optimal side lobe level (SLL), by changing the parameters like number of elements in an array, eccentricity, number of rings, and distance between rings. Simulation results show that the thinned Elliptical cylindrical antenna side lobe level is less when compare to concentric elliptical antenna and it is reduced up to −34 db.
