| Abstract: | The electromagnetic simulation technique plays an important role in modern antenna design. This paper discussed an antenna simulation and optimization method combining Genetic Algorithm (GA). The proposed antenna design method employing GA can design a new kind of antenna structure and easily adjust the antenna structure parameter. Based on the introduction of the principle of GA, this paper introduced the application problem of GA in antenna simulation and optimization. Furthermore,this paper used the VBS cript to combine the Genetic Algorithm and the Ansoft HFSS, and optimized a dual polarized millimeter wave microstrip antenna employing electromagnetic coupling feed. The voltage standing wave ratio (VSWR) bandwidth of the discussed antenna was increased and the technical requirements of designed antenna were met,
which shows the feasibility of antenna simulation and optimization method based on GA. |
