研究目的
To present a novel multi-frequency GNSS antenna based on a dielectric resonator (DR) with in-band filtering, introducing a "decoupling network" for improved performance.
研究成果
The presented dielectric resonator-based GNSS antenna concept shows improvements in realized gain, impedance bandwidth, antenna height reduction, and introduces an in-band filtering response. The "decoupling network" contributes to performance improvements, though its exact impact requires further study. Future work will focus on size reduction and further evaluation of the "decoupling network" concept.
研究不足
The "decoupling network" did not demonstrate all of the anticipated properties, and the exact contribution factor is not clear at this time. The bandwidth of the filtering response is narrow and subject to further investigations.
1：Experimental Design and Method Selection:
The antenna design is based on a hollow cylinder DR with four feeding ports and a novel "decoupling network".
2：Sample Selection and Data Sources:
The DR is made of C-STOCK AK-12 material, and the decoupling network is manufactured as a single layer one-sided flexible printed circuit board.
3：List of Experimental Equipment and Materials:
Includes a Rogers TMM 10i(TM) material PCB, C-STOCK AK-12 DR, and DuPont? Kapton? polymide film for the decoupling network.
4：Experimental Procedures and Operational Workflow:
The antenna was simulated using HFSS, with detailed dimensions and materials specified.
5：Data Analysis Methods:
The performance was evaluated based on reflection coefficients, realized gain, coupling coefficients, and radiation patterns.
