Pattern synthesize of a cylindrical conformal array antenna by PSO algorithm

Pattern synthesize of conformal array antennas is often a challenging problem. Various optimization algorithms such as genetic, particle swarm optimization (PSO), and invasive weed optimization have already been used for pattern synthesizing of conformal arrays. In this paper, a focused beam is synthesized for a quarter cylindrical conformal array antenna using the PSO algorithm with small computations. The desired pattern is a focused beam at theta = 90 degrees and phi = 45 degrees with 10 degrees beamwidth in elevation and 15 degrees beamwidth in azimuth with -20 dB side-lobe level. This method can be used in general for synthesizing arbitrary desired patterns and array geometries.
