Abstract
In this paper an azimuthally periodic wedgeshaped circular aperture frequency selective surface FSS is discussed which provides the dual polarized and angular stable frequency response with significantly more fractional bandwidth FBW up to 50° angleofincidence AOI at Sband Kuband and Kaband In addition to this the equivalent circuit EC parameters of proposed bandpass FSS structure are obtained using the transmissionline approach which are further utilized to compute the geometrical parameters of the proposed bandpass FSS structure at 3 15 and 25 GHz The numerical results computed by transmissionline approach are supported with the simulation results which have been obtained using commercially available simulators such as CST Microwave Studio finite integral technique and Ansoft HFSS finite element method at each frequency of interestThe authors are sincerely thankful to the anonymous reviewer for critical comments and suggestions to improve the quality of the manuscript and also to the Indian Space Research Organization vide Project No ISRO/RES/4/579/1011 for the financial aid
