摘要
从方环缝隙型频率选择表面(FSS)出发,利用有限元法的电磁仿真计算软件(HFSS),对微带天线与有限大面积的FSS阵列进行了一体化建模和仿真,确定了FSS结构与微带天线间的最佳距离。同时还研究分析了在不同工作频率下,FSS结构的空间位置与天线间的关系,FSS结构单元个数变化等情况下的天线增益方向图的变化。
An integrated system that consists of finite FSS array with band-pass response and microstrip antenna is designed based on the square loop slot FSS＇ s transmission characteristic. The simulation models are established and analyzed by using the software HFSS based on the FEM method. The results indicate that the microstrip antenna＇ s performance is influenced by different degrees in the cases of different sized FSS and different distances between finite FSS array and micrstrip antenna. Besides, the circumstance of microstrip antenna loaded with finite FSS array in different operating frequency is also analyzed.
