| Outline of Final Research Achievements |
In this research, we studied on low loss millimeter wave narrow band filters. The database of material constants in 30-110GHz band, which are used for the filter design, was constructed and expanded by using the cutoff circular waveguide method , the empty cavity resonator method and the dielectric resonator based method. We realized 2-pole narrow bandpass filter with center frequency of 29.7GHz, relative bandwidth of 0.9%, and insertion loss of 2.4dB using CPW type circular slot resonator at room temperature. Moreover, design procedure of H slot resonator with high Q and good spurious characteristic are proposed. We designed 30GHz band 2-pole bandpass filter using H slot resonator. We have been shown the possibility of a millimeter wave band filter with sharp skirt response using the H slot resonator by 3D FEM simulation.
