| Abstract: | A meta-material structure which is optimized by combining genetic algorithm in Matlab and simulation in HFSS is introduced.A structure which has surface wave band gap is designed to suppress surface wave,as well as enhance gain performance.The optimization process of the algorithm is effectively accelerated by saving and querying the optimized records.Through simulation results,it is found that the microstrip antenna with the structure of new electromagnetic material,work on 5.8 GHz,gain is increased by 1.8 dB,and back radiation is reduced by 3.8 dB,and electromagnetic signal acquisition ability of antenna is improved. |
