Design of linear array for WLAN applications using genetic algorithm

In this paper a new technique for design of a linear array of seven elements with non uniform spacing and non uniform amplitude excitation to achieve low side-lobe level (SLL) for a chosen beam width is proposed. Inter element spacing between the antenna elements is based on a Genetic Algorithm technique and amplitude excitations are the coefficients of a binomial series. Genetic Algorithm for SLL reduction and achieving low side lobe levels from a linear array of uniform elements is implemented using simulation tools.
