Particle Swarm Optimization with Aging Leader and Challengers (ALC-PSO) method, which represents a novel approach for optimization problems, is applied for radiation pattern synthesis of a three ring Concentric Elliptical Array Antenna (CEA) of isotropic elements which can generate beam pattern with maximum reduced Side Lobe Level (SLL). This paper introduces a recently developed metaheuristic algorithm,...
In this paper, the optimal thinning of two-ring Concentric Hexagonal Array (CHA) of uniformly excited isotropic antennas which can generate directive beam with minimum relative Side Lobe Level (SLL) is described. The Improved Particle Swarm Optimization (IPSO) method, which represents a new approach for optimization problems in electromagnetic, is used in the optimization process. To determine an...
This paper describes optimal thinning of Concentric Hexagonal Array (CHA) of uniformly excited isotropic antennas which can generate directive beam with minimum relative Side Lobe Level (SLL). The Craziness Based Particle Swarm Optimization (CRPSO) method, which represents a new approach for optimization problems in electromagnetics, is used in the optimization process. The CRPSO is used to determine...
Particle Swarm Optimization (PSO) is applied to the thinning of elliptical antenna arrays of uniformly excited isotropic antennas which can generate directive beam with minimum relative side lobe level (SLL). Thinning of elliptical antenna arrays using PSO are optimized with different values of eccentricity in all the cases and variation of side lobe level with eccentricity of thinned antenna array...
