摘要：Design of thinned elliptical antenna arrays of uniformly excited isotropic antennas using particle swarm optimization (PSO), is reported. Thinned arrays can generate directive beam with minimum side lobe level (SLL) without degrading the performance of fully populated antenna arrays significantly. Thinning of elliptical antenna arrays using PSO are optimized with different values of eccentricity and variation of side lobe level with eccentricity of thinned antenna array is reported. Using optimization method, it is found that by changing eccentricity of elliptic arrangement of an antenna array, reduced side lobe levels can be obtained. Thinning of concentric elliptical array, using PSO, is also reported in this paper.
