基于HFSS双频带通型频率选择表面的研究

摘要

The frequency selective surface is a specific periodic structure which has a filtering effect on signals of a specific frequency.It is important in radar and antenna systems.In this paper, a dual-frequency frequency selection surface is designed which works on C-band and X-band radars and the design is based on the software HFSS, which is a kind of three-dimensional electromagnetic simulation software. The center frequencies are 6GHz and 10 GHz respectively. An expected result is achieved by simulation and optimization.%频率选择表面是一种特定的周期结构, 对特定频率的信号具有筛选作用, 特别是在雷达和天线系统中具有重要作用.文章针工作于C波段和X波段的雷达, 基于HFSS三维电磁仿真软件, 设计了一种双通带频率选择表面, 中心频率分别为6 GHz和10 GHz, 通过仿真和优化, 达到预期效果.
