Abstract (in Japanese) (See Japanese page) 
(in English) In this work, a novel quasi-millimeter-wave ultra wideband (UWB) bandpass filter (BPF) is designed by using a microstrip dual-mode ring resonator and half-wavelength resonators. The transmission line equivalent circuit of the filter is analyzed based on the even- and odd-mode method, and design formulas are derived for determining the frequencies of the reflection zeros in the passband and the transmission zeros in the stopband, as well as the half-power frequencies. Variations of the frequency response of the filter versus the circuit parameters are investigated using the obtained formulas and circuit simulators. A compact UWB BPF with a midband frequency of 25.5 GHZ and a fractional bandwidth of 22% is designed, and the desired wide passband, sharp skirt, and wide stopband are realized simultaneously, which meet well the FCC’s UWB spectrum mask.
