Practical validation of null optimized TMLAA obtained by PSOIIW

Abstract

Important aspect of antenna array optimization is to validate the obtained results in a practical environment. This paper presents the practical validation of time modulated linear antenna arrays (TMLAA) with optimized radiation pattern using EM simulator. The optimization is done by using particle swarm optimization with improved inertia weight (PSOIIW) algorithm approach. Computer simulation technology-microwave studio (CST-MWS) is used as EM simulator. Dipole element is taken as elemental pattern for pattern multiplication with the array factor (AF) of isotropic linear antenna array, which gives the equivalent results of TMLAA of dipole elements. Half wave dipole has been designed, with its resonant frequency 2 GHz. Different sets of antenna array along with MATLAB simulation results have been shown in this paper.
