Abstract
A dielectric resonator which has a simple structure and is easy to manufacture, and a dielectric filter and a communication apparatus using the same are provided. In a dielectric resonator, a dielectric body includes a first portion having surfaces and a second portion having surfaces. A conductor surrounding the dielectric body includes inner surfaces facing the surfaces. A conductor is disposed between the surface and the inner surface. A conductor is disposed between the surface and the inner surface. The dielectric body includes a third portion which is not interposed between the conductors and a fourth portion which is not interposed between conductors.
Claims6
A dielectric resonator, comprising:
- a dielectric body;
- a first conductor;
- a second conductor;
- a third conductor;
- a fourth conductor;
- and
- a fifth conductor,
- the dielectric body including
- a first portion which has a first surface located at an end in a first direction of the first portion and a second surface located at an end in a second direction opposite to the first direction of the first portion, the first portion having a columnar shape, and
- a second portion which has a third surface located at an end in a third direction perpendicular to the first direction of the second portion and a fourth surface located at an end in a fourth direction opposite to the third direction of the second portion, the second portion having a columnar shape,
- the first portion and the second portion crossing each other,
- the first conductor being disposed such that the dielectric body is housed in a cavity formed therein, the first conductor being disposed so as to surround the dielectric body leaving space therefrom, the first conductor having a first inner surface facing the first surface, a second inner surface facing the second surface, a third inner surface facing the third surface, and a fourth inner surface facing the fourth surface,
- the second conductor being disposed on the first surface, an end in the first direction of the second conductor being electrically connected to the first inner surface,
- the third conductor being disposed on the second surface, an end in the second direction of the third conductor being electrically connected to the second inner surface,
- the fourth conductor being disposed on the third surface, an end in the third direction of fourth conductor being electrically connected to the third inner surface,
- the fifth conductor being disposed on the fourth surface, an end in the fourth direction of the fifth conductor being electrically connected to the fourth inner surface,
- the dielectric body including a third portion which is a portion of the first portion which is not interposed between the second conductor and the third conductor, and a fourth portion which is a portion of the second portion which is not interposed between the fourth conductor and the fifth conductor.
