摘要
本文设计了一种新型紧凑的贴片型(带阻型)频率选择表面,该频率选择表面的周期单元由双环及连接贴片构成。本文通过对方形环的等效电路进行分析,合理分布金属贴片的位置,使得频率选择表面具有较小的周期尺寸,能够较好地抑制高阶模的产生,并增加插入损耗。利用HFSS软件对该频率选择表面进行优化,对不同角度的入射波进行仿真,结构体现出较好稳定性。最后通过实验测试,所得结果与仿真结果较为吻合,-15d B插入损耗覆盖整个L频段。
A novel compact stop-band FSS structure is proposed in this paper. The FSS is consist of two square loops with different sizes and four metal patch to link the loops. The physical length and other parameters of the patches is optimized by equivalent circuit method and the commercial software HFSS. The final unit has a compact structure to reject the high floquet mode and surface wave. Moreover, the sample FSS is fabricated, and the measurement result is agree with the simulation, which $21 is below -15dB over the L-band.
