摘要

采用镀膜和光刻技术设计并制备出了2种衬底厚度不同的Y孔单元和Y环孔单元的FSS

在0°和45°入射角下分不同的极化波进行了测试

经对比研究发现

在大角度入射下Y环单元FSS比Y孔单元FSS有更为稳定的中心频率

更窄的带宽;Y环单元FSS对垂直和水平极化波的适应性更强

滤波特性较Y孔单元FSS更明显;介质厚度的变化对Y孔中心频率、带宽的影响要比Y环单元FSS的大得多。所以

从中心频率、带宽随介质衬底厚度、入射角度、不同极化方式的变化情况看

Y环单元比Y孔有更稳定的性能。

Abstract

With filming technology and lithography

two sorts of FSS i.e. Y-aperture element FSS and Y-loop element FSS on different thickness substrates are presented. And the tests under two different polarized waves at 0° and 45° incidence angle are given. The results show that at wide angle

Y-loop element FSS has more stable center frequency and narrower bandwidth than Y-aperture element FSS; Y-loop element FSS is more adaptive to vertically and horizontally polarized wave than Y-aperture element FSS

and its filtering characteristic is more obvious as well; The center frequency and bandwidth of Y-aperture are much more influenced by the substrate thickness change than those of Y-loop element FSS. So from the changes in center frequency and bandwidth versus dielectric substrate thickness

incident angle

direction of polarization

it can be seen that Y-loop element has more stable characteristics than Y-aperture.
