Dielectric resonator capable of suppressing spurious mode
First Claim
1. A dielectric resonator for suppressing spurious modes comprising:
- a cylindrical block of dielectric material having flat surfaces on the ends thereof; and
at least one straight, thin, electrically conducting bar member provided approximately in alignment with the axis of said cylindrical block of dielectric material and approximately in alignment with the direction of the electric field produced by propagation of a spurious mode in said cylindrical block of dielectric material and said bar member being in other than a retaining relationship with said cylindrical block of dielectric material, whereby said electric field produced by the spurious mode produces a current in said bar member thereby consuming the energy of the spurious mode in the bar member for suppressing the spurious mode.

Abstract
The present disclosure relates to a dielectric resonator for use in microwave filters and other devices for receiving microwave. The arrangement of the present disclosure comprises a resonator made of a dielectric material of any known type and a bar member provided approximately in alignment with the direction of formation of the electric field produced by the propagation of a spurious mode in the dielectric resonator. During the propagation of the dominant mode accompanied by the spurious mode, the electric field produced by the spurious mode causes the bar member to produce a current flowing therethrough, thus consuming the energy of the spurious mode in the bar member, and substantially eliminating the spurious mode.
