Document Type and Number:
WIPO Patent Application WO/2015/076255
Kind Code:
A1
Abstract:
[Problem] To provide a dielectric resonator having good electrical characteristics, a dielectric filter using this dielectric resonator, and a communication device.
[Solution] A dielectric resonator which comprises: a columnar dielectric body (70) which has a surface (21) positioned at the end in a first direction and a surface (22) positioned at the end in a second direction that is opposite to the first direction; a conductor (11) which is arranged so as to surround the dielectric body (70) with a space therebetween and has an inner surface (31) facing the surface (21) and an inner surface (32) facing the surface (22); a columnar conductor (12) which is arranged between the surface (21) and the inner surface (31); a columnar conductor (13) which is arranged between the surface (22) and the inner surface (32); a conductor (14) which is arranged between the conductor (12) and the conductor (11) in a third direction that is perpendicular to the first direction; and a conductor (15) which is arranged between the conductor (13) and the conductor (11) in a fourth direction that is perpendicular to the first direction.
