研究目的
To propose substrate integrated waveguide (SIW) multi-channel filtering crossovers for two sets of intersecting signals operating at the same or different frequencies, with independently extended filtering channels in two directions.
研究成果
The proposed SIW multi-channel filtering crossovers feature easy extension of filter channels, good inter-channel isolation, and controllable operating frequencies, making them useful in wireless systems.
研究不足
The design complexity and layout constraints may limit the extension of channel number beyond certain points. Fabrication tolerance of slots may cause slight frequency deviations.
1：Experimental Design and Method Selection:
Utilizes square SIW cavities with TE102 and TE201 modes as building blocks, arranging feeding ports and coupling regions for isolation and bandpass responses.
2：Sample Selection and Data Sources:
Designs include a six- and a five-channel filtering crossover with the same operating frequency, and a four-channel crossover with different operating frequencies.
3：List of Experimental Equipment and Materials:
Substrate with dielectric constant of 2.6, loss tangent of 0.0015, and thickness of 0.762 mm.
4：6, loss tangent of 0015, and thickness of 762 mm.
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Fabrication of crossovers, simulation using HFSS, and measurement with Keysight Network Analyzer E5071C.
5：1C.
Data Analysis Methods:
5. Data Analysis Methods: Comparison of simulated and measured results to verify performance.
