Abstract

A thin film resonator for a wireless power transmission is provided. The thin film resonator may include a first transmission line unit provided as a thin film type, a second transmission line unit also provided as the thin film type, and a capacitor inserted at a predetermined position of the first transmission line unit.

Claims

1. A resonator for a wireless power transmission, the resonator comprising:

a first transmission line unit provided as a thin film type;

a second transmission line unit provided as the thin film type; and

a capacitor that is inserted at a predetermined position of the first transmission line unit.

2. The resonator of claim 1, wherein the capacitor is configured such that the thin film resonator has a property of a metamaterial.

3. The resonator of claim 1, wherein the capacitor is configured such that the thin film resonator has a zero magnetic permeability or a negative magnetic permeability at a target frequency.

4. The resonator of claim 1, wherein the first transmission line unit and the second transmission line unit are configured to form a stacked structure.

5. The resonator of claim 4, wherein the stacked structure of the first transmission line unit and the second transmission line unit comprises a ferromagnetic substance or a magneto-dielectric structure.

6. The resonator of claim 1, further comprising:

a micro-strip line to supply an electric current to the first transmission line unit.

7. The resonator of claim 1, further comprising:

a bonding layer to bond the resonator to an object.

8. A resonator for a wireless power transmission, the resonator comprising:

a transmission line unit provided as a thin film type and having a gap;

a second transmission line unit provided as the thin film type;

an opening between the firs transmission line unit and the second transmission line unit, and

a capacitor inserted in the opening between the first transmission line unit and the second transmission line unit.

9. The resonator of claim 8, wherein the first transmission line unit comprises one or more vias disposed near the opening and the second transmission line unit comprises one or more vias disposed near the opening.
