Dielectric resonator apparatus
First Claim
1. A dielectric resonator apparatus, comprising a case member, at least two dielectric resonators accommodated within the case member, an input means for inputting electromagnetic wave energy into the case member, and an output means for outputting electromagnetic wave energy from the case member to the outside, each of the resonators having a flattened shape including a pair of outer planes each forming an electric wall and having first ends at which said outer planes are crossed at a given angle with each other, along a line which coincides with a central axis of the electromagnetic field distribution in the operating mode of the resonator, and another surface extending between second ends of said outer planes, and all of the resonators being arranged along an axis common to the central axis of each of the resonators so that they couple inductively with each other in the axial direction of the resonators.

Abstract
The dielectric resonator apparatus is characterized in that electric walls exist on one plane or two including the central axis of the electromagnetic field distribution in the using mode of a dielectric resonator, a dielectric resonator with either of dielectrics between the electric wall being removed in shape is provided by plurality, an equivalent axis is common to the central axis of each of the dielectric resonators, with the dielectric resonators being inductively coupled in the axial direction. A dielectric resonator which prevents the current from being concentrated on the central axis of the electromagnetic field distribution, is collectively smaller in the Joule loss and is higher in Q. The dielectric resonator of the present invention is characterized in that the dielectric close to the central axis is removed, wherein electric walls exist on one plane or two including the central axis of the electromagnetic field distribution in a dielectric resonator using, for instance, a TE01δ mode, with either of dielectrics between the electric wall being removed in shape.
