Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents novel and simple-structured tunable resonators for tunable bandpass filter that individually varies the center frequency and bandwidth. The resonator consists of a ring resonator, switches and tunable reactive elements such as varactors. Resonant frequency of the resonator is changed by varying the characteristics of tunable reactive elements. Bandwidth is also changed by choosing one on-state switch from many switches.
