Design of Thinned Linear Antenna Array using Particle Swarm Optimization (PSO) Algorithm
This paper describes the unwanted side lobe
level reduction of thinned linear array antenna using
particle swarm optimization (PSO) algorithm. In
RADAR and satellite communication, very low side
lobe level is required. The purpose of this paper is to
reduce side lobe level of linear antenna array using
optimization technique. Thinning of an antenna array
involves switching ‘ON’ some antenna elements and
rest all the elements are switched ‘OFF’. Turning ‘OFF’
some of the antenna elements do not degrade the
system performance. The investigations presented in
this paper may be useful for Direct Broadcast Satellite
