Abstract
The present invention has been made in an effort to overcome the disadvantage that a user has to consciously adjust the positions of a wireless power transmitter and a wireless power receiver. The transmitting antenna for wireless power charging, which wirelessly transmits power to charge a device, includes a first antenna coil section for producing a magnetic field in a first direction, and a second antenna coil section for producing a magnetic field in a second direction. Accordingly, the three-dimensional transmitting antenna can minimize decreases in efficiency caused by the position and direction of the receiver and maximize reception efficiency at a particular point or within a particular range.
