Genetic Algorithm in Broadband Microstrip Antenna Design
Genetic algorithm is utilized in the optimization of microstrip antenna with complicated structure. The authors have proposed a broadband single-patch microstrip patch antenna. The Capacitance compensated technique and an E-shaped patch are combined together to expand the bandwidth of this antenna. Genetic algorithm combined with Finite Element software is applied to optimize the structure of this antenna. The procedure for optimization is also discussed on this platform. The reliability and efficiency of this method is proved by comparing the antenna proposed in this paper to an un-optimized one. It can be clearly observed that the bandwidth expands from 6% of the un-optimized one to 16% of its capacity.
