Azimuthally periodic wedge-shaped metal vane loaded circular ring frequency selective surface

In this paper, the analysis and simulation of a novel geometrical structure of the frequency selective surface (FSS), which has been achieved through the conductive loading of the simple circular ring with wedge-shaped metal vanes has been discussed. The electrical performance and behavior of the proposed structure have been studied in Ku band (12-18 GHz) of the electromagnetic spectrum for satellite communication. We have radially optimized the proposed structure to enhance the performance, such as reflection and transmission bandwidth. We have also discussed the effect of incident electric field at 0°, 10°, 30°, and 50° on the electrical performance of the proposed FSS. In addition to this, the effect of angular sensitivity on the proposed structure through increasing the number of conductive loaded wedge-shaped metal vanes is also explored. However, the structural parameters of the proposed FSS have been obtained through the synthesis technique. The analytical results obtained from the synthesis technique have been supported by the simulation results achieved through CST Microwave Studio as well as Ansoft high frequency structural simulator (HFSS), which are commercially available simulators based on the finite integral and finite-element technique, respectively. Furthermore, for validation of the numerical results, the Ansoft circuit simulator which is based on mixed potential integral equations (MPIE) and solved by the method-of-moment has also been used to obtain the reflection and transmission parameters through the values of inductance and capacitance, which have been achieved by the numerical analysis.
