Analysis and Optimization of a Circular Fractal Array Antenna Using PSO Algorithm

Amir Rezagholi, Farzad Mohajeri

A fractal antenna is created by repeating a motif over two or more scale sizes, or "iterations". For this reason, fractal antennas are very compact, multiband or wideband, and have useful applications in cellular telephone and microwave communications. In this paper, we will investigate the multiband characteristics of a fractal array based on a 4-element circular subarray generator, and will optimize it for the maximum directivity using Particle Swarm Optimization (PSO) algorithm
