研究目的
Investigating the construction and performance of leaky wave antennas based on spoof surface plasmon polaritons (SSPP) waveguides for application in fifth-generation (5G) mobile communication systems.
研究成果
The introduction of truncation gaps to the periodic SSPP waveguide allows the guided wave to be radiated into free space, enabling the construction of a dual-port leakage antenna with beam sweep function. A single-port antenna, formed by halving the dual-port antenna, exhibits good directivity and beam sweep function, making it suitable for application in fifth-generation (5G) mobile communication systems.
研究不足
The single-port antenna has a relatively narrower operating band and slightly higher sidelobe level compared to the dual-port antenna. The low-frequency end of the single-port antenna can be extended by improving the structural parameters to cover the 5G band.
1：Experimental Design and Method Selection:
The study involves the design of a dual-port and a single-port leaky wave antenna based on SSPP waveguides with periodic truncation slits to achieve mode conversion and radiation.
2：Sample Selection and Data Sources:
The antennas are constructed on a single-sided copper-coated Rogers RO4350B substrate.
3：List of Experimental Equipment and Materials:
The study uses a vector network analyzer AV3629D for scattering characteristics testing and SATIMO Starlab antenna measurement system for directivity testing.
4：Experimental Procedures and Operational Workflow:
The antennas are designed with specific structural dimensions and tested for their scattering parameters, electric field distributions, and radiation patterns.
5：Data Analysis Methods:
The performance of the antennas is analyzed based on their scattering parameters, electric field distributions, and radiation patterns.
