Synthesis of large thinned planar antenna arrays using modified binary coded genetic algorithm

Abstract

In the present study, a pencil beam pattern synthesis of uniformly excited large thinned planar antenna (LTPA) arrays is proposed. The aim is to find out the best positions of 'ON' and 'OFF' elements in the antenna array corresponding to the lowest possible peak side lobe level (PSLL). Modified binary coded genetic algorithm (MBC-GA) is utilized to determine the optimum solution with less computational cost. In order to evaluate the performance of proposed method, a 32∗48-element LTPA array is considered for numerical analysis. © 2017 IEEE.
