Floating-point Genetic Algorithm for design of a Reconfigurable Antenna Arrays by phase-only control

摘要

In this paper we propose a floating-point Genetic Algorithm (GA) for optimal design of a reconfigurable antenna array by varying only the phase excitations of the radiators while fixing the common amplitude distribution constant. This common amplitude distribution is jointly optimized with phases to generate dual beam pattern antenna array. Results show a good agreement between the desired and GA synthesized pattern. Results are very encouraging even without minimizing the amplitude excitation dynamic range ratio (DRR).
