Abstract
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.
