Abstract: Disclosed is a resonator for expanding a transfer distance. A conical resonator includes a metal layer configured to operate according to a resonant frequency, and a dielectric layer coupled to the top or bottom of the metal layer to space the metal layer apart from another metal layer without overlap, wherein the metal layer and the dielectric layer have a Swiss-roll structure, and include an input face to which power is supplied on the bottom and an open face on the top.
