研究目的
To design a dual-band, high-gain resonant cavity antenna using a frequency selective surface (FSS) layer for millimeter wave wireless communication and small satellite communication terminals.
研究成果
The proposed dual-band, high-gain resonant cavity antenna using a frequency selective surface (FSS) layer successfully enhances gain at two adjacent frequency bands. This design is suitable for millimeter wave wireless communication and small satellite communication terminals. Future studies could explore the use of multiple FSS layers for further gain improvement.
研究不足
The study focuses on simulation results; practical implementation and testing in real-world scenarios are not covered. The design's performance is limited to specific frequency bands (S and C bands).
1：Experimental Design and Method Selection:
The design involves a cylindrical dielectric resonator antenna (CDRA) excited by a microstrip line through a rectangular slot cut from the ground surface. A frequency selective surface (FSS) layer is used to enhance the antenna's gain.
2：Sample Selection and Data Sources:
The antenna is simulated to resonate at two adjacent frequency bands (S and C bands).
3：List of Experimental Equipment and Materials:
The antenna uses a cylindrical DRA, microstrip line, and a single layer 5 X 5 array superstrate.
4：Experimental Procedures and Operational Workflow:
The CDRA is excited by the microstrip line through the rectangular slot, and the FSS layer is placed above the DRA with an air gap to enhance gain.
5：Data Analysis Methods:
The antenna's performance is analyzed through simulation results, focusing on resonance frequencies and gain enhancement.
