Apparatuses, systems, and methods of wireless power transmission/reception are described. In one wireless power transmission/reception device, a planar resonator capable of generating magnetic fields has one or more ferrite members mounted thereon such that the magnetic fields generated by the planar resonator have an overall direction substantially tilted or parallel to its opening/face, i.e., to the plane of the planar resonator. In a wireless power reception device, the planar resonator generates magnetic fields and an induced current when being resonated by external magnetic fields; in a wireless power transmission device, the planar resonator generates magnetic fields when being supplied with power.

Wireless power transmission/reception device

An antenna device attains good antenna performance using at least one or more metal members installed in a portable terminal. The antenna device includes a main board equipped with a power supply part for supplying power, a slot part which is positioned in at least one or more metal members or is formed by a combination of the metal members, and a power supply antenna member for receiving power from the power supply part and which is electromagnetically coupled with the slot part.
