Document Type and Number:
WIPO Patent Application WO/2021/106731
Kind Code:
A1
Abstract:
A bandpass filter comprising a plurality of electromagnetically coupled resonators. At least one of the plurality of resonators is a specific resonator to which an external signal is input or which outputs a signal externally. The specific resonator comprises: a conductor pin; a first surrounding conductor radially surrounding the conductor pin; a dielectric body positioned between the conductor pin and the surrounding conductor; a second surrounding conductor surrounding the dielectric body from an axial direction of the conductor pin; and an intermediate conductor extending in a direction transverse to the axial direction of the conductor pin and electrically connecting the conductor pin and the first surrounding conductor or the second surrounding conductor.
