A miniaturized multiband bandstop frequency selective surface (FSS) based on square loop structures with wideband spurious rejection is proposed. This structure can eliminate the spurious frequency up to 30 GHz when the loop structure act as a spatial band stop filter at 7.2 GHz. Significant capacitor achieved by parasitic patch loading of the structure create a new resonance at a lower frequency when the lumped inductor added and made a new compact multiband FSS structure. The proposed FSSs has similar attribute for TE and TM incident polarizations, also. Moreover, the measurement results show good agreement with the simulation ones. The simplicity, compact size, flexibility in multiband tuning, wideband spurious rejection and insensitive polarization operation verify the ability and capability of the proposed structure for many applications. © 2017 Wiley Periodicals, Inc.
