Evolved Multiobjective Low Side-lobe Taper for Beam Steerable Arrays

Antennas and arrays are indispensable elements of wireless communication systems. The directional characteristics is one of the most attractive features of antenna arrays. This article takes up a case of array pattern synthesis, and adopts two contemporary and highly competitive Evolutionary Algorithms, named Nondominated Sorting Genetic Algorithm III (NSGA III), and Double Niched Evolution Strategy for solving Multimodal Multiobjective Problems (DN-MMOES). The results show the effectiveness of Evolutionary Algorithms for such problems.
