Abstract

The paper presents a new technique for designing a reconfigurable frequency selective surface (RFSS) by mechanical means. The combination of triangular loop element and three-legged element has been used to design the proposed single substrate two sided frequency selective surface (FSS) structure which offers variable transmission coefficient characteristics over the X-band frequencies under TE polarization for different angles of incidence. Thus, the band stop characteristics can be reconfigured by changing incident angle which describes the structure as `reconfigurable reflector'. The proposed FSS geometry is polarization insensitive under both TE and TM polarizations. The simulated results are further cross verified by conducting measurement of the fabricated structure. The equivalent circuit model (ECM) of the proposed FSS geometry has been provided, and the equivalent circuit parameters of the proposed FSS geometry have also been extracted using the curve fitting techniques. The proposed FSS structure can be used as a frequency reconfigurable reflector surface/reconfigurable intelligent surface (RIS) for advanced wireless communication.
