Abstract

In this paper, a novel method for the synthesis of shaped-beam antenna arrays by combining matrix resolution with particle swarm optimization (PSO) algorithm is proposed. The amplitude and phase distribution of the antenna array are achieved firstly by matrix resolution, and then the results are used as the initial values of PSO algorithm in the following optimization to obtain a wide angle shaped-beam radiation pattern. As examples, an 18-element antenna array and a 24-element antenna array are synthesized. The results show that the optimization algorithm can improve the shaped-beam precision and it is an effective method for solving the wide angle shaped-beam problem when the element number of the antenna array is small.
