Abstract

A resonator structure for a wireless power transfer system Includes resonators, which are to transfer wireless power, and a dielectric substance, which includes at least one exposure region formed on the dielectric substance to fix the resonators in a covered shape and to selectively expose parts of the resonators.

Claims

1. A resonator structure for a wireless power transfer system, comprising:

a resonator, which is to transfer wireless power; and

a dielectric substance to cover the resonator and fix the resonator therein,

wherein the dielectric substance includes at least one exposure region to selectively expose at least one portion of the resonator.

2. The resonator structure of claim 1, wherein the resonator has a circular spiral structure.

3. The resonator structure of claim 2, wherein the resonator is a conductor plate having a predetermined line width and line thickness.

4. The resonator structure of claim 2, wherein the dielectric substance has a center cavity which is formed in a center region of the spiral structure.

5. The resonator structure of claim 2, wherein a center cavity is defined entirely through the dielectric substance at a center region of the spiral structure.

6. The resonator structure of claim 1, wherein the resonator has a rectangular spiral structure.

7. The resonator structure of claim 6, wherein the resonator is a conductor plate having a predetermined line width and line thickness.

8. A resonator structure for a wireless power transfer system, comprising:

resonators, which are in a form of a rectangle to transfer wireless power; and

a dielectric substance, which includes a plurality of dielectric branches that extend in outward directions based on a center of the rectangle to fix each part of the resonators in a covered form.

9. The resonator structure of claim 8, wherein the plurality of dielectric branches include four dielectric branches which extend in four directions based on the center.

10. The resonator structure of claim 8, wherein the resonator is a conductor plate of a spiral structure having a predetermined line width and line thickness.

11. A resonator structure for a wireless power transfer system, comprising:

resonators, which are in a form of circles to transfer wireless power; and

a dielectric substance, which includes a plurality of dielectric branches that extend in diametrically opposed directions based on a center of the circle to fix each part of the resonators in a covered shape.

12. The resonator structure of claim 11, wherein the resonator is a conductor plate of a spiral structure having a predetermined line width and line thickness.

13. The resonator structure of claim 12, wherein the dielectric substance has a circular center cavity which is formed in a center region of the dielectric branches in the circle.

14. The resonator structure of claim 12, wherein the plurality of dielectric branches include eight dielectric branches which extend in eight directions based on the center.
