Novel Wideband Frequency Selective Surface Based Space Borne Filters for Sub-6 GHz 5G Devices

Abstract

TA novel square slotted frequency selective surface (FSS) depicting identical performance at oblique angle of incidence is proposed. This new type of FSS is the modification of a square loop FSS and it exhibits a stable response. The designed prototype of an array of double square slotted frequency selective surface (DSSFSS) is fabricated and the measured results are compared with the simulation results performed with a Finite Element Method (FEM) solver i.e. Ansys High Frequency Structure Simulator (HFSS). The transmission response is stable under oblique angles of incidence ranging from 0 to 60 degrees. The effect of the variation of main design parameters on the characteristics of the DSSFSS has been investigated.
