Coupler for tuning resonant cavities
View Patent ↗Various exemplary embodiments relate to an improved coupler for resonant cavities and dielectric resonators. The coupler may permit accurate tuning of electromagnetic signals within desired frequency ranges. The coupler may be secured to a movable tuning device by a plurality of securing members. Each securing member may be separate, having no contact with any other securing member.
1. A system for enhanced tuning of dielectric resonators, the system comprising:
a first dielectric resonator that produces electromagnetic signals within a first range of frequencies;
a second dielectric resonator that produces electromagnetic signals within a second range of frequencies;
a movable tuning device disposed in an aperture between the first dielectric resonator and the second dielectric resonator; and
a coupler secured to the movable tuning device, wherein the coupler transfers electromagnetic signals between the first dielectric resonator and the first dielectric resonator and comprises a plurality of securing members that extend radially inwardly toward the movable tuning device to secure the coupler to the movable tuning device, each of the securing members being spaced apart from all other securing members.
2. The system of claim 1 , wherein the coupler further comprises:
an outer member that is concentric relative to the movable tuning device, wherein a width of the outer member is proportional to a tuning range for the electromagnetic signals in the aperture.
3. The system of claim 2 , wherein the coupler further comprises:
clamping members that hold the plurality of securing members against the movable tuning device.
4. The system of claim 3 , wherein each clamping member comprises a pair of prongs, wherein the pair of prongs secures the coupler to the movable tuning device.
5. The system of claim 2 , wherein the plurality of securing members comprise at least four securing members that extend radially inwardly from the outer member toward the movable tuning device.
6. The system of claim 2 , wherein the plurality of non-contiguous securing members comprise at least eight securing members that extend radially inwardly from the outer member toward the movable tuning device.
7. The system of claim 1 , wherein the coupler further comprises:
an outer member that is concentric relative to the movable tuning device, wherein an external surface of the outer member is hexahedral in shape.
8. The system of claim 7 , wherein the plurality of securing members comprise at least four securing members that extend inwardly from the outer member toward the movable tuning device.
9. The system of claim 1 , wherein the coupler further comprises:
an outer member that is concentric relative to the movable tuning device, wherein an external surface of the outer member is octagonally prismatic in shape.
10. The system of claim 9 , wherein the plurality of securing members comprise at least eight securing members that extend inwardly from the outer member toward the movable tuning device.
11. A system for enhanced tuning of electromagnetic signals in resonant cavities, the system comprising:
a movable tuning device for placement in an aperture between a first resonant cavity and a second resonant cavity, wherein a vertical axis of the movable tuning device is parallel to respective vertical axes of the first resonant cavity and the second resonant cavity; and
a coupler secured to the movable tuning device, wherein the coupler transfers electromagnetic signals between the first resonant cavity and the second resonant cavity and comprises a plurality of securing members that extend radially inwardly toward the movable tuning device to secure the coupler to the movable tuning device, each of the securing members being spaced apart from all other securing members.
12. The system of claim 11 , wherein the coupler further comprises:
an outer member that is concentric relative to the movable tuning device, wherein a width of the outer member is proportional to a tuning range for the electromagnetic signals in the aperture.
13. The system of claim 12 , wherein the coupler further comprises:
clamping members that hold the plurality of securing members against the movable tuning device.
14. The system of claim 13 , wherein each clamping member comprises a pair of prongs, wherein the pair of prongs secures the coupler to the movable tuning device.
15. The system of claim 12 , wherein the plurality of securing members comprise at least four securing members that extend radially inwardly from the outer member toward the movable tuning device.
16. The system of claim 12 , wherein the plurality of securing members comprise at least eight securing members that extend radially inwardly from the outer member toward the movable tuning device.
17. The system of claim 11 , wherein the coupler further comprises:
an outer member that is concentric relative to the movable tuning device, wherein an external surface of the outer member is hexahedral in shape.
18. The system of claim 17 , wherein the plurality of securing members comprise at least four securing members that extend inwardly from the outer member toward the movable tuning device.
19. The system of claim 11 , wherein the coupler further comprises:
an outer member that is concentric relative to the movable tuning device, wherein an external surface of the outer member is octagonally prismatic in shape.
20. The system of claim 19 , wherein the plurality of securing members comprise at least eight securing members that extend inwardly from the outer member toward the movable tuning device.
