Optimization by genetic algorithm of a PIFA antenna parameters for Wifi application

In this paper a genetic algorithm optimization is applied to optimize PIFA antenna parameters for wireless application. The optimization procedure is included, also two novel optimized antennas are presented. Optimized antennas reach 89.93% and 88.55% bandwidth. Miniaturization is also achieved. The reliability and efficiency of this method are proved by comparing the antenna proposed in this paper to optimal antennas.
