Abstract

The present invention relates to a multi-mode resonator comprising: a housing in which a cavity corresponding to a substantially single accommodating space is arranged; and multiple resonance ribs which are arranged at a predetermined interval therebetween in the cavity, have lower ends fixed to a floor surface of the housing, have upper ends facing each other, and generate a resonance signal by multiple coupling therebetween.

First claim

What is claimed is:

1. A multi-mode resonator comprising:
a housing provided with a cavity corresponding to a substantially single accommodation space; and
a plurality of resonance ribs which are arranged with a predetermined interval therebetween in the cavity, have lower ends fixed to a bottom surface of the housing, and have upper ends facing each other to generate a resonant signal based on multiple coupling therebetween.

2. The multi-mode resonator of claim 1 , wherein the lower ends of the plurality of resonance ribs are globally integrally connected by a single connecting auxiliary support having a ring shape.

3. The multi-mode resonator of claim 1 , wherein the lower ends of the plurality of resonance ribs are connected globally integrally with the housing in such a way to extend from a lower end surface of the housing, a hole portion for integral manufacturing with the plurality of resonance ribs is formed on the lower end surface of the housing, and a closure for stopping the hole portion is provided.

4. The multi-mode resonator of claim 1 , wherein a number of the plurality of resonance ribs is 3, 4, or 6.

5. The multi-mode resonator of claim 1 , further comprising a tuning screw installed in a center of an entire arrangement structure of the plurality of resonance ribs to pass through from an upper end of the housing.

6. The multi-mode resonator of claim 1 , further comprising an input probe and an output probe for exchanging input and output signals with one pair of resonance ribs among the plurality of resonance ribs.

7. The multi-mode resonator of claim 1 , wherein the cavity has a polyhedral shape.

8. The multi-mode resonator of claim 1 , wherein the plurality of resonance ribs are arranged with an equal interval therebetween.

9. The multi-mode resonator of claim 1 , wherein at least one partition is installed between the plurality of resonance ribs.

10. The multi-mode resonator of claim 1 , wherein at least one of the plurality of resonance ribs has a different length.

11. The multi-mode resonator of claim 1 , wherein at least one of the plurality of resonance ribs has a different height from the lower ends.

12. The multi-mode resonator of claim 1 , wherein the plurality of resonance ribs have a bar shape that is globally bent in an arch shape.

13. The multi-mode resonator of claim 12 , wherein a cross-sectional shape of the plurality of resonance ribs is substantially circular.

14. The multi-mode resonator of claim 12 , wherein at least a part of the upper ends of the plurality of resonance ribs is cut.
