研究目的
To propose a cascade design procedure integrating segmented approach with space mapping technique for efficient EM-based design optimization of high order microwave bandpass filters.
研究成果
The proposed cascade filter design method integrating segmented approach with space mapping technique is proven to be very efficient for EM based high-order filter design, as validated by the design and optimization of a 10-pole hairpin filter.
研究不足
The method's efficiency is dependent on the accuracy of the coarse model and the computational resources available for EM simulations.
1：Experimental Design and Method Selection:
The design approach divides an entire filter design into small segmented stages, integrating space mapping technique for optimization.
2：Sample Selection and Data Sources:
A 10-pole Chebyshev microstrip hairpin bandpass filter is designed and optimized.
3：List of Experimental Equipment and Materials:
Keysight ADS for coarse model and Sonnet EM simulator for fine model.
4：Experimental Procedures and Operational Workflow:
Segmented design stages are completed sequentially, optimizing no more than three design parameters in each stage.
5：Data Analysis Methods:
The method aims to match the simulated group delay response to the objective group delay targets.
