Design of Broadband Microstrip Antenna Utilizing Genetic Algorithm
نویسندگان
چکیده
Genetic Algorithm combined with Finite Element software is applied to design a single-patch broadband microstrip patch antenna in this paper. The optimization procedure is also included. The broad-band character is realized by taking out some parts of the ordinary patch antenna. The reliability and efficiency of this method are proved by comparing the antenna proposed in this paper to un-optimized patch antenna. It can be seen that the bandwidth expands from 6% of the un-optimized one to 17.8%.
