雷达罩壁双层FSS电结构设计与选择

Electrical Configuration Design for the Double Layer FSS on Radome Application

研究了双层Y形缝隙谐振表面应用于雷达罩FSS设计时罩壁结构的平面波传输特性，分析讨论了几种不同双层结构频率特性的差异并得到结论，嵌于介质层之间的FSS结构可以获得较为稳定的谐振带宽，并且能够有效地缩减双层FSS结构传输系数谐振区域中的凹沟。

The plane wave transmission properties of the double layer Y slotted array applied in the FSS radome configuration designing is studied in this paper. After the frequency properties of several double layer FSS configurations be analyzed, we concluded that by embedding the slotted arrays between the dielectric layers, we can acquire a relative stable transmission band, and the deep dip appear in the resonance region of the double layer FSS can also be reduced by appreciate choosing the dielectric parameters.
