BAND STOP AND BAND PASS FREQUENCY SELECTIVE SURFACE WITH MINIATURIZED ELEMENT IN LOW FREQUENCIES

Abstract
In this paper, two single-band frequency selective surfaces (FSS) for low frequency stop and pass band with miniaturized element have been proposed. A square loop patch is constructed to realize single stop band responses. Similarly, a square with slot is constructed to realize a single pass band response at lower frequencies. Pass band is realized by slot while stop band is realized by a patch. Both pass band and stop band FSS structure having dimensions 25mm×25mm×1.605mm. FSS structures are designed and simulated using CST MWS V’16 with unit cell boundary along X and Y axis and floquet ports. Simulated results show that proposed FSS structures for both pass band and stop band are independent of angle of incidence and polarisation. Axial ratio bandwidth of the proposed FSS structure (<3dB) for bandwidth 1GHz. Equivalent circuits of the stop band and pass band FSS structures shows series and parallel combination of inductance and capacitance respectively.
