Optimization of Resonant Frequency of Circular Patch Microstrip Antenna Using Particle Swarm Optimization

Abstract

In this paper, a robust stochastic algorithm called Particle Swarm Optimization (PSO) is used to optimize resonant frequency of circular microstrip patch antenna. A modified formula for resonant frequency is presented using PSO. The obtained results using particle swarm optimization has been compared with experimental and theoretical values of previous papers. The results were in good agreement with experimental value with an average error of 0.18%.
