A NOVEL SIMPLE CONVOLUTED GEOMETRY TO DESIGN FREQUENCY SELECTIVE SURFACES FOR APPLICATIONS AT ISM AND UNII BANDS
Keywords:FSS, Novel Convoluted Geometry, Dual-band Response, ISM, UNII
In this paper, we use a novel convoluted geometry to design a dual-band Frequency Selective Surface (FSS) with angular stability and independent polarization operation. The geometry allows the design of a dual-band FSS to block ISM and UNII radio bands. We performed a parametric study with the commercial software ANSYS HFSS. A prototype of the designed FSS was built and its transmission characteristics were measured and compared with simulated results. We observed good agreement between numerical and experimental results. The FSS realized a dual-band response at the required bands and it had angular stability and polarization independence.
