DIELECTRIC RESONATOR, DIELECTRIC FILTER, AND COMMUNICATION APPARATUS

摘要

A dielectric resonator includes a columnar dielectric body having a surface located at an end in a first direction thereof and a surface located at an end in a second direction opposite to the first direction thereof, a conductor which is disposed so as to surround the dielectric body leaving space therefrom, and has an inner surface opposed to the surface and an inner surface opposed to the surface, a columnar conductor disposed between the surface and the inner surface, a conductor disposed between the conductor and the conductor in a third direction perpendicular to the first direction, and a conductor disposed between the conductor and the conductor in a fourth direction perpendicular to the first direction.

1. A dielectric resonator, comprising:
a dielectric body having a first surface located at an end in a first direction thereof and a second surface which is located at an end in a second direction opposite to the first direction thereof; a first conductor having a cavity formed therein in which the dielectric body is housed, the first conductor being disposed so as to surround the dielectric body leaving space therefrom, and having a first inner surface including a part opposed to the first surface, and a second inner surface including a part opposed to the second surface; a second conductor disposed on the first surface, an end in the first direction thereof being electrically connected to the first inner surface; a third conductor disposed on the second surface, an end in the second direction thereof being electrically connected to the second inner surface; a fourth conductor disposed between the second conductor and the first conductor in a third direction perpendicular to the first direction, an end in the first direction thereof and an end in the third direction thereof being electrically connected to the first conductor, an end in a direction opposite to the third direction thereof being electrically connected to the second conductor; and a fifth conductor disposed between the third conductor and the first conductor in a fourth direction perpendicular to the first direction, an end in the fourth direction thereof and an end in the second direction thereof being electrically connected to the first conductor, an end in a direction opposite to the fourth direction thereof being electrically connected to the third conductor.
