Abstract:

Miniaturization of Frequency Selective Surface’s (FSS’s) size is significant for its application in the limited space. In this paper, a novel methodology for designing low-profile FSS is discussed, and a corresponding multi-layer structure with lumped elements for band-pass response is presented. Based on the equivalent circuit theory, the inductive designed center layer is firstly discussed. Then different numbers of additional capacitive designed layers are added and their performances are presented. Finally, the lumped elements are added both between adjacent layers and between adjacent cells of the additional layers so that the miniaturization performance can be further improved. The simulations for each structure in waves of different polarizations and incident angles are conducted, and the results are presented, which demonstrate the claimed characteristics of the proposed structure.

Key words:  FSS  miniaturization  multi-layer  polarization stability
