Abstract
A wireless power transmitting apparatus transmits an electric power signal comprising any one from among an electric field, a magnetic field, and an electromagnetic field to a wireless power receiving apparatus. A reflector coil is arranged at a distance from a radiation coil. A driving power supply supplies a driving current to the radiation coil. A first phase control circuit controls the phase of the current that flows through the reflector coil so as to stabilize, to a predetermined value, the phase difference between the current that flows through the reflector coil and the current that flows through the radiation coil.
