研究目的
Investigating the design of mixed quarter- and one-eighth modes substrate integrated waveguide (SIW) bandpass ?lter (BPF) for compact size and higher performance in wireless systems.
研究成果
The proposed SIW BPF with mixed quarter- and one-eighth mode cavities provides low insertion loss, compact circuit size, and wide stopband performance with high selectivity. The measurements are consistent with the simulations, validating the design approach.
研究不足
The study is limited to the design and performance evaluation of SIW BPFs at a center frequency of 8 GHz. The potential for optimization and application in other frequency bands is not explored.
1：Experimental Design and Method Selection:
The design rationale involves using mixed quarter- and one-eighth modes SIW cavities to achieve wide stopband response and high selectivity. Theoretical models and algorithms are employed to design two- and three-stage SIW BPFs with Chebyshev response at a center frequency of 8 GHz.
2：Sample Selection and Data Sources:
The samples are the designed SIW BPFs, with data acquired through simulation and measurement.
3：List of Experimental Equipment and Materials:
RT/Duroid 5880 substrate with εr =
4：2, tan δ = 0009, and thickness h = 508 mm is used. HFSS 2019R3 is used for simulation. Experimental Procedures and Operational Workflow:
The BPFs are designed, simulated, fabricated, and measured. The external quality factors and coupling coefficients are calculated and adjusted.
5：Data Analysis Methods:
The S-parameter magnitudes are analyzed to evaluate the performance of the BPFs.
