Abstract (in Japanese) (See Japanese page) 
(in English) In this work, a quasi-millimeter-wave wideband bandpass filter (BPF) and a millimeter-wave wideband BPF are designed respectively by using a microstrip dual-mode ring resonator and half-wavelength resonators. Based on the transmission line equivalent circuit of the filter, variations of the frequency response of the filter versus the circuit parameters are investigated first by using the derived formulas and circuit simulators. Then a BPF with a fractional bandwidth (FBW) of 20% at 25GHz and BPF with a FBW of 10% at 60GHz are designed, and both filters realize the desired wide passband, sharp skirt property, and very wide stopband. Finally, the designed BPF at 25 GHz is fabricated, and its measured frequency response agrees well with the simulated result.
