Research Abstract |
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.
