An Efficient Design Methodology for Fabry-Perot Cavity Antenna

A wideband design technique of a Fabry-Perot cavity antenna (FPCA) is presented based on Particle Swarm Optimization (PSO) algorithm. The proposed method appears to be very efficient as the optimization technique is driven by commercial electromagnetic simulator. Ten antenna parameters have been handled successfully to achieve a wide band optimized result. About 16.8 dBi maximum broadside gain has been achieved using the optimally designed antenna. Peak gain is maintained above 11 dBi over the 50% impedance bandwidth of the antenna.
