Cylindrical antenna array synthesis with minimum side lobe level using PSO technique

Particle Swarm Optimization (PSO) Algorithmwith the Schelkunoff method is used to synthesize the conformal array. Evolutionary Techniques are in rise in electromagnetic as design tools and problem solvers because of their ability to optimize complex multimodal search spaces. This paper discusses the design and optimization of cylindrical antenna arrays with special emphasis on traditional polynomial Schelkunoff method coupled with the PSO Algorithm in application to the K U band. It also illustrates the implementation procedure of PSO algorithm in electromagnetic optimizationproblems. The optimization procedure is then used to design cylindrical antenna array with specific array factor requirements. A comparative study of design tools is done through simulation.
