英文摘要： Reconfigurable filter is an essential component in smart wireless communication systems. How to get the reconfigurable filters which can meet the requirements of miniaturization, integration and better functionality within wideband is not only an extremely challenging fundamental research, but also the urgent needs for multiband and multifunctional wireless communication systems. In this proposal, compact reconfigurable filters with large tuning range and high flexibility in bandwidth and filter shape reconfiguration will be researched by using simultaneous electric and magnetic two-dimensionally tuning method. The research are including: (1) the investigation on the key physical mechanism of simultaneous electric and magnetic two-dimensionally reconfiguration; (2) the theoretical methodology for the synthesis of electric and magnetic two-dimensionally tuned bandpass filters and the application to design of tunable filters with independent control of center frequency, bandwidth and filter response shape; (3) the key techniques of efficiently designing and realizing multiband, multi-degree reconfigurable filters with simultaneous electric and magnetic two-dimensionally tuning. By theoretical analysis, electromagnetic simulation and experimental verification, the method of design, analysis and synthesis of reconfigurable filters with high precision will be established. Furthermore, the best architecture, reliable theoretical analysis, high-efficiency design method, and some initial models verified by principle experiments will be provided for high-performance and compact electric and magnetic two-dimensionally tuned parameter-agile SIW filters.
