Design of an all-dielectric band-stop frequency selective surface

摘要

Design of an all-dielectric band-stop frequency selective surface (FSS) is proposed for X-band application. The unit particle of the FSS consists of a thick upper hexagonal prism part and a thin lower hexagonal prism part for monolithic construction. The proposed FSS has planar array of hexagonal ceramic prisms having a honey comb-shaped structure. The proposed FSS has three resonant dips. Those are combined to establish a broad stop-band of 24.4 % (center frequency of 10 GHz) -10-dB fractional bandwidth (FBW). To demonstrate resonant characteristic modes, the cylindrical cavity mode analysis based on the cylindrical wave functions is used.
