摘要: In this paper, an azimuthally periodic wedge-shaped circular aperture frequency selective surface (FSS) is discussed, which provides the dual polarized and angular stable response with significantly more fractional bandwidth (FBW) up to 50° angle-of-incidence (AOI) at S-band, Ku-band Ka-band. addition this, equivalent circuit (EC) parameters of proposed bandpass FSS structure are obtained using transmission-line approach, further utilized compute geometrical 3, 15 25 GHz. The numerical results computed by approach supported simulation results, have been commercially available simulators such as CST Microwave Studio (finite integral technique) Ansoft HFSS element method) each interest.
