Multilayer Band-pass Frequency Selective Surface with Sharp Roll-off Characteristic

Yan Zhang, Qidi Wu, Juan Xu

Abstract

In this paper, proposed a new kind of frequency selective surface (FSS) with sharp roll-off. The structure consists of three metal layers and two layers of dielectric substrate, the top and bottom is the resonance layer, the middle is the coupling layer, on both sides of the passband introduces two transmission zeros, greatly improve the option characteristic of the FSS, make it have high selectivity. The simulation results of FSS show that it generates two transmission poles at 17.35GHz and 17.45GHz, and two transmission zeros at 16.6GHz and 18.7GHz, with good angular stability and polarization stability.
