Abstract :
In this paper, the method of nullifying the radiation pattern of a symmetrical linear antenna array in a particular direction is propounded using Particle Swarm Optimization with Constriction Factor Approach (PSOCFA). Single or multiple wide nulls are achieved by optimum perturbations of elements current amplitude weights to have either symmetric nulls about the main beam. Different numerical examples are presented to illustrate the capability of PSOCFA for pattern synthesis with a prescribed wide nulls locations and depths.
