Various embodiments of the present disclosure relate to a wireless charging system. The wireless charging system may include: a system body mounted with a power transmission part including a cavity shielded by a conductive material, a power feeding radiator configured to feed power within the cavity to form a resonance mode, and a slot formed at a location with a maximum E-field by the power feeding radiator to form a power transmission route with E-field coupling; and an electronic device including a power reception part mounted on the system body to receive power from the slot through H-field coupling. Various embodiments may be made.

Wireless charging system

A magnetic stripe transmission (MST) apparatus that improves a recognition rate and operates at a low current is provided. The apparatus includes a first coil disposed between a first power supply source and a second power supply source, and wound in a first direction, a second coil connected in parallel to the first coil, disposed between the first power supply source and the second power supply source, and wound in a second direction, a first driver disposed between the first coil and the second power supply source, and configured to control a first current of the first coil according to a first voltage pulse supplied by a first pulse supply source, and a second driver disposed between the second coil and the second power supply source, and configured to control a second current of the second coil according to a second voltage pulse supplied by a second pulse supply source.

Apparatus and method for implementing magnetic stripe transmission circuit

An antenna apparatus having a device carrier made of a magneto-dielectric material is provided. The antenna apparatus includes a device carrier having a magnetic carrier made of a magneto-dielectric material, and an antenna device connectable to a power source through a feeding point of one end portion and extended from the feeding point to pass through a surface of the magnetic carrier and operable in a resonant frequency band when power is supplied through the feeding point. Therefore, by forming at least a portion of the device carrier with a magnetic carrier, an operating performance of the antenna apparatus can be improved.
