Single-layer Miniaturized Loaded Frequency Selective Surfaces with Enhanced Bandwidth
In this paper,a novel single-layer miniaturized loaded frequency selective surface (FSS) with enhanced bandwidth operating over the GPS and DCS 1800 frequency band is presented,in which each periodic cell consists of double square loops with different capacitive loadings.To eliminate the undesired coupling between unit cells,the unit cells are placed in the substrate integrated waveguide (SIW) cavity structure.A Sband FSS with such structures is designed,the simulated results show that a band-pass bandwidth of 24.5％ (1.49GHz to 1.88GHz) is obtained with an insertion loss of less than 3dB for scan angles up to 45 degree in both TE and TM polarization while the bandwidth of normal loaded FSS is about 3％-5％.Furthermore the FSS dimension is miniaturized to 0.08 (λ refer to the resonant wavelength).
