Abstract

This paper presents a new optimization technique for the design of linear antenna arrays. The proposed technique is based on a novel variant of PSO called Boolean PSO with Adaptive Velocity Mutation. The antenna arrays are optimized under requirements for maximizing the power gain at a desired direction and minimizing the side lobe level of the radiation pattern. The impedance-matching condition of all the array elements is also required by the algorithm. The optimization technique has been developed considering that the array elements are excited by uniform-amplitude current distribution. The radiation characteristics of the antenna array are extracted by using the method of moments. The technique has been applied in several broadside and non-broadside cases of collinear wire-dipole antenna arrays and seems to be capable of improving the radiation characteristics of the antenna arrays in practice.
