研究目的
To propose a Ku-band bandpass frequency selective surface (FSS) with high selectivity and miniaturization using two metallic strips and one slot, incorporating both electrical and magnetic couplings, and to verify the design through fabrication and measurement.
研究成果
The proposed Ku-band FSS with high-selectivity and miniaturization has been successfully designed, fabricated, and measured. The structure exhibits a narrow passband with two transmission zeros, enhancing selectivity. The use of a metallic via allows for miniaturization without changing the operating model or requiring bulk components. The measured results agree well with simulations, validating the design.
研究不足
The measured results show a slight shift in the center frequency and transmission zeros, possibly due to fabrication errors. The performance begins to deteriorate at an incident angle of 30 degrees.
1：Experimental Design and Method Selection:
The FSS structure is designed using two metallic strips and one slot for electrical and magnetic couplings, with a metallic via for miniaturization. An equivalent-circuit model is analyzed using the odd- and even-mode method.
2：Sample Selection and Data Sources:
A prototype of the proposed FSS operating at 16 GHz is fabricated and measured.
3：List of Experimental Equipment and Materials:
Rogers RO3035 with relative permittivity of 3.5 and loss tangent of 0.0015 is used to support the three-layered structure. The prototype is measured using two standard antennas and Keysight vector network analyser (VNA) N5244A.
4：5 and loss tangent of 0015 is used to support the three-layered structure. The prototype is measured using two standard antennas and Keysight vector network analyser (VNA) N5244A.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The FSS structure is simulated under normal incident wave by CST using Floquet boundary. The prototype is measured in an anechoic chamber.
5：Data Analysis Methods:
The measured results are compared with full-wave and circuit simulation results.
