摘要： PROBLEM TO BE SOLVED: To provide the dielectric resonator device in which a dielectric core can be easily supported in a cavity so as to eliminate cost-up factor and a problem with a decrease of a resonant frequency of a TM mode in which an electric field vector passes through a support is solved, the dielectric filter having it, the composite dielectric filter and the communication apparatus.
SOLUTION: An outside dimension of a support plate 3 is made larger than that of a bottom face of a dielectric core 10 contacting with this support plate 3 and the support plate 3 is fixed on a bottom face of an inner side of a cavity 1 with support columns 2 at a periphery of the support plate 3. Accordingly, an air layer A is provided between the bottom face of an inner side of a cavity 1 and the support plate 3 and a resonant frequency of a TMz mode in which a direction of the electric field vector is perpendicular to the surface of the support plate 3 is increased so as to be kept considerably away from a resonant frequency of an TM01δ multi-mode to be used.

摘要： PROBLEM TO BE SOLVED: To provide a dielectric resonator wherein two resonance modes are coupled with a prescribed coupling amount and respective resonance frequencies have differences, and to provide a dielectric filter employing the dielectric resonator to obtain a desired filter characteristic, a composite dielectric filter and a small-sized low cost communication apparatus employing them.
SOLUTION: The dielectric resonator is characterized in that a hole 15 is formed in a position different from both a first virtual plane VS1 including two ridges in parallel with each other and in a diagonal positional relation and a second virtual plane VS2 including the two other ridges in parallel with the two ridges and in a diagonal positional relation. Further, the dielectric resonator is characterized in that the coupling coefficient of the two resonance modes depends on a distance D between the center (o) of the dielectric resonator and the hole 15, and a difference between the resonance frequencies of the two resonance modes is decided depending on deviation (d) from the virtual plane VS2.

The dielectric resonator is characterized by coupling two resonance modes (TE01δx mode and TE01δy mode) by a difference between volumes of the first and second missing parts. Then the dielectric resonator is characterized in that the coupling amount is decreasingly adjusted by expanding either of the missing parts 11b, 11b' which has a smaller volume.
