| Abstract(in English) | In this paper, we examine the resonance characteristics when the distributed tap-coupling is applied to a λ/2 resonator, and the impedance step strucutre is applied to the loading part and the resonator itself. It is confirmed that the attenuation poles are arranged near the center frequency and spurious responses near the passband are away from the center frequency by using the impedance steps to loading and resonator parts. We also confirm that the impedance step can be applied to the resonator part and the length of the proposed resonator be shortened compared with the conventional type by using impedance step to the resonator part. |
