中文摘要
在本研究中,我们研究了高Q值谐振器和窄带滤波器的结构。采用截止圆波导法和WG模谐振器法建立了30- 110 GHz波段毫米波材料常数数据库,用于滤波器的设计。此外,我们还研制了低温条件下Q值高达15000的平面型30 GHz谐振器和室温条件下Q值高达5000的NRD波导型60 GHz谐振器。数值计算表明,采用这种谐振器的窄带滤波器的插入损耗可提高1.5-3dB。
英文摘要
In this research, we studied structures of high Q resonators and narrow band filters. The database of millimeter wave material constants in 30-110GHz band, which are used for the filter design, was constructed by using the cutoff circular waveguide method and the WG mode resonator method. Moreover, we developed a planar type 30GHz resonator with high Q value of 15000 under low temperature condition, and a NRD guide type 60GHz resonator with high Q value of 5000 under room temperature condition. It is verified numerically that the narrow band filters using these resonators can be improved the value of insertion loss about 1.5-3dB.
