Abstract

Official abstract text for this publication.

A coaxial resonance coil having a toroidal shape for wireless power transmission is provided. The coaxial resonance coil may include a central conductive wire used as a power feeding loop for indirectly feeding power to a resonance coil, and an outer conductive wire used as a resonance coil which is wound a plurality of turns in a toroidal shape around the central conductive wire as an axis.

First claim

Opening claim text (preview).

What is claimed is: 1 . A coaxial resonance coil having a toroidal shape for wireless power transmission, comprising: a central conductive wire used as a power feeding loop which indirectly feeds power to a resonance coil; and an outer conductive wire used as a resonance coil which is wound a plurality of turns in a toroidal shape around the central conductive wire as an axis. 2 . The coaxial resonance coil of claim 1 , wherein the central conductive wire is formed to have a circular shape, a rectangular shape, or a solenoid shape 3 . The coaxial resonance coil of claim 1 , wherein an outer cover having a non-conductive material is formed on each of the central conductive wire and the outer conductive wire. 4 . The coaxial resonance coil of claim 1 , wherein the central conductive wire and the outer conductive wire are configured to be arranged inside one outer cover having a non-conductive material in a form of a coaxial resonance cable. 5 . The coaxial resonance coil of claim 1 , wherein the outer conductive wire is at least one resonance coil which is manufactured as an open type. 6 . The coaxial resonance coil of claim 1 , wherein the outer conductive wire is at least one resonance coil which is manufactured as a closed type 7 . The coaxial resonance coil of claim 6 , wherein a capacitor is connected to the at least one resonance coil. 8 . The coaxial resonance coil of claim 7 , wherein the capacitor is a variable capacitor. 9 . The coaxial resonance coil of claim 7 , wherein the capacitor is integrated with an adaptor. 10 . The coaxial resonance coil of claim 3 , wherein a distance between the central conductive wire and the outer conductive wire is adjusted by adjusting a thickness of the outer cover of the central conductive wire. 11 . The coaxial resonance coil of claim 1 , wherein the resonance coil is arranged in a plurality of layers with respect to the central conductive wire as an axis. 12 . The coaxial resonance coil of claim 1 , wherein the resonance coil is implemented in a prefabricated type using a connection device.
