研究目的
To propose a six-port network based on double ridge gap waveguide (DRGW) for microwave and millimeter-wave measurement, marking the first attempt to design such a network using gap waveguide technology.
研究成果
The proposed DRGW six-port network demonstrates good agreement with theoretical calculations, suitable for Ka-band measurement systems and receiver designs. The simulation confirms the network's operational frequency and bandwidth, along with satisfactory phase and amplitude performance indicators.
研究不足
The study is based on simulation results, and practical implementation may face challenges related to manufacturing tolerances and material properties. The operational bandwidth is limited to 8.5% at 40 GHz.
1：Experimental Design and Method Selection:
The design involves creating a six-port network using DRGW technology, focusing on the development of a DRGW power divider and a DRGW 90 degrees - 3dB coupler as fundamental elements.
2：Sample Selection and Data Sources:
The study utilizes simulation data to evaluate the performance of the designed six-port network.
3：List of Experimental Equipment and Materials:
The design is based on all-metal construction with specific dimensions.
4：Experimental Procedures and Operational Workflow:
The process includes designing the double pin with mirror symmetry of the DRGW, followed by the design of the DRGW power divider and coupler, and finally combining these components to form the six-port network.
5：Data Analysis Methods:
Performance is evaluated through simulation, focusing on reflection coefficients, insertion loss, and phase differences between ports.
