Particle swarm optimization and method of moments for modeling and optimization of microstrip antennas

This paper introduces a novel technique for efficiently combining Particle Swarm Optimization (PSO) with method of moments (MOM) for computing the resonant frequency and bandwidth of rectangular microstrip antenna. In this technique, the problem is formulated in terms of an integral equation which is the kernel of a dyadic Green's function. After this PSO which will be introduce to determinate antenna parameters by optimizing the impedance matrix |Z|. The resonant frequency results obtained by using (PSO/MOM) algorithm are in very good agreement with the experimental results available in the literature. The computation time is greatly reduced as compared to the classical MOM.
