A comparison of NSGA-II, DEMO, and EM-MOPSO for the multi-objective design of concentric rings antenna arrays

Abstract

A comparison between different modern multi-objective optimization methods applied to the design of concentric rings antenna arrays is presented in this paper. This design of concentric rings antenna arrays considers the optimization of the amplitude and phase excitations across the antenna elements in order to generate the trade-off curves between side lobe level and directivity for a scannable pattern with optimal performance in the whole azimuth plane. Simulation results by using evolutionary multi-objective optimization methods, such as: NSGA-II, DEMO, and EM-MOPSO are provided in this document. Furthermore, a comparative analysis of the performance between these algorithms is presented.
