In this paper, an evolutionary swarm intelligence technique; Craziness Particle Swarm Optimization (CRPSO) is propounded for nullifying the radiation pattern of a symmetrical linear antenna array in a particular direction. Multiple wide nulls are achieved by optimum perturbations of elements current amplitude weights to have symmetric nulls about the main beam. Different numerical examples are presented to illustrate the capability of CRPSO for pattern synthesis with a prescribed wide nulls locations and depths. Further, the peak sidelobe levels are also reduces when compared to a uniformly excited array having equal number of elements.
