Abstract
An efficient global optimization algorithm based on the Particle Swarm Optimization approach is developed and applied for synthesis of a linear antenna array with a flat-top beam. A flowchart of the algorithm is provided along with a discussion on the impacts of different factors affecting the algorithm performance, namely its convergence rate and quality of the final solution. Finally, the optimal values of the algorithm parameters (weight coefficients and boundary condition type) for the considered problem are determined via systematic parametric study.
KEY WORDS: global optimization, particle swarm optimization, electromagnetic synthesis, antenna arrays, antenna synthesis, flat-top beams
