Abstract :
A circularly polarized antenna was designed using dipoles for the driven elements, and loops for the reflector and director elements. The optimization of the antenna was performed using the Particle Swarm Optimization (PSO) and Bounded Optimization By Quadratic Approximation algorithms (BOBYQA). Both algorithms yielded identical results, though the execution times for the BOBYQA routine proved to significantly shorter.
