Genetic algorithm optimization of a dual polarized concentric ring array

Abstract : We use a genetic algorithm to minimize the Relative Sidelobe Level (RSLL) of a dual polarized concentric ring array. The optimization variables are the placement of uniformly weight spiral antennas in an aperture with a small area. We used isotropic sources for the optimization and the topology used is the concentric ring array. The computation of the Array Factor (AF) of the topology used is expensive and many function calls are required during the optimization, so we developed approaches to obtain a faster cost function and reduce the number of function calls.
