研究目的
To design a polarization independent and angularly stable FSS elements with improved performance characteristics for microwave frequencies.
研究成果
The proposed Faraday cage inspired Jerusalem Cross FSS structure shows an improvement of 11.52% bandwidth over its conventional form and is very stable for a wide angle of incidence from 0o to 60o. The structure is suitable for high power microwave applications and is easy and cost-effective to fabricate using conventional PCB process.
研究不足
The vias in the proposed structure may increase the design complexity. However, it provides mechanically and angularly stable FSS with high power handling capabilities.
1：Experimental Design and Method Selection:
The design involves a novel Faraday cage inspired frequency selective surface (FSS) array for patch-type periodic elements, using metallic vias to connect two patch conducting arrays printed on either side of the substrate.
2：Sample Selection and Data Sources:
The structure is designed to operate at the center frequency of X-band regime (10 GHz), using Jerusalem Cross (JC) FSS array.
3：List of Experimental Equipment and Materials:
The array is printed with copper on either side of a dielectric substrate, with thin cylindrical holes drilled and coated with copper to form the metallic cage.
4：Experimental Procedures and Operational Workflow:
The resonance characteristics are estimated using a commercial FDTD based full wave simulator (CST Microwave StudioTM).
5：Data Analysis Methods:
The transmission parameters and phase response are analyzed to evaluate the performance.
