Title:
DIELECTRIC RESONATOR, DIELECTRIC FILTER, AND MULTIPLEXER
Document Type and Number:
WIPO Patent Application WO/2021/106443
Kind Code:
A1
Abstract:
The present invention realizes: improvement in Q factor of a dielectric resonator; and lower-loss performance of a dielectric filter. The dielectric resonator is provided with a dielectric substrate (100), a distributed constant element (231), and a shield conductor part (150). The distributed constant element (2) extends in the X-axis direction within the dielectric substrate (100). The shield conductor part (150) is formed on the surface of the dielectric substrate (100) in such a manner as to wrap around the distributed constant element (231) when the distributed constant element (231) is viewed in a planar view from the X-axis direction. One end of the distributed constant element (231) is not connected to the shield conductor part (150). The distributed constant element (231) comprises a plurality of conductors (241).
