发明名称	Coaxial resonator and dielectric filter formed from a dielectric block with at least one inner conductor surrounded by a non-conductive recess
摘要	A coaxial resonator includes a dielectric block; a first inner conductor disposed in an inner surface of a first through hole which extends from a first main surface of the dielectric block to an opposite second main surface thereof, the first inner conductor being connected to a reference potential at one side thereof; and an outer conductor disposed over side surfaces of the dielectric block, the outer conductor surrounding the first inner conductor, the outer conductor being connected to the reference potential. There is a low-dielectric-constant portion in a location between the first inner conductor and the outer conductor. The low-dielectric-constant portion surrounds a periphery of the first inner conductor and is lower in dielectric constant than the dielectric block.

主权项	1. A coaxial resonator, comprising: a dielectric block; a first inner conductor disposed in an inner surface of a first through hole that extends from a first main surface of the dielectric block to an opposite second main surface thereof, the first inner conductor being connected to a reference potential at a side thereof toward the first main surface; and an outer conductor disposed over side surfaces of the dielectric block, the outer conductor surrounding the first inner conductor, the outer conductor being connected to the reference potential, wherein there is a low-dielectric-constant portion in a location between the first inner conductor and the outer conductor, the low-dielectric-constant portion surrounds a periphery of the first inner conductor, the low-dielectric-constant portion is lower in dielectric constant than the dielectric block, the low-dielectric-constant portion is a recess that is disposed in the first main surface of the dielectric block, the recess continuously surrounds the periphery of the first inner conductor, and an inner surface of the recess is a conductor-free region.
