Investigation on Realistic Synthesis Approach for Shaped Beam Patterns and its validation through EM Simulation study

In this study, authors aimed to develop a realistic strategy to synthesized shaped beam antenna, which is of major practical concern. A particle swarm optimization (PSO) technique is employed to compute required excitation coefficients of array elements agreeing to the desired shape of the radiation pattern. Authors considered cosecant and flat-topped beam patterns to illustrate the perfectibility of the purposed approach. In addition, an EM simulation study is performed to further validate the potentiality of the proposed approach in constructing the practical arrays.
