研究目的
To design a broadband interconnect between Substrate Integrated Suspended Line (SISL) and Substrate Integrated Waveguide (SIW) at 28 GHz band.
研究成果
The paper successfully designs an SISL-to-SIW transition at 28GHz with broadband performance, demonstrating the potential for SISL's broader application in microwave systems. However, improvements are necessary to reduce insertion loss and enhance matching.
研究不足
The insertion loss and matching effect need further improvement to enhance the transition's performance.
1：Experimental Design and Method Selection:
The design involves a taper structure for broadband performance, focusing on single-mode propagation by suppressing the TE10 mode in SISL and ensuring quasi-TEM mode generation.
2：Sample Selection and Data Sources:
The study uses simulated data from HFSS to evaluate the performance of the SISL-to-SIW interconnect.
3：List of Experimental Equipment and Materials:
FR4_epoxy and Rogers RT/duroid 5880 substrates, metal layers (G1–G10) with a thickness of 0.035 mm.
4：035 mm.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow:
The design process includes the creation of a multi-layer substrate cavity to form a metal cavity, optimizing the interconnect structure for low loss and broadband performance.
5：Data Analysis Methods:
Performance is assessed based on return loss and insertion loss measurements over the 24-34 GHz frequency range.
