Analysis of Rectangular Planar Array with Different Distributions and Optimization of Sidelobe Level using GA and PSO

Abstract

In this paper, analysis of rectangular planar antenna array(RPAA) with different amplitude distributions like uniform, binomial and Dolph-Tschebyshev distributions is done. Comparison of radiation characteristics of rectangular planar arrays with different amplitude distributions is done. The sidelobe level (SLL) is optimized using genetic algorithm (GA) based optimization and particle swarm optimization (PSO) techniques.
