A Hybrid Structure Design of Broadband band-pass MEFSS and FSS

Miniaturized element frequency selective surface (MEFSS) design technology is one of the research hotspots in recent years, the application space of frequency selective surface (FSS) has been expanded, especially in low-frequency applications, surface shaping applications and other fields. In this paper, we provide a design of MEFSS unit and loaded on the dual screen FSS. Compared with the original dual screen FSS, the simulation results shows that the hybrid structure with loading MEFSS present a wider bandwidth, giving faster roll off in sidebands, and the cut-off is obviously improved, it also can ensure insensitivity to incident angle variation and polarization.
