Abstract
A wireless power transmitting device includes: an upper coil including a first tubular spiral coil and a first planar spiral coil disposed beneath the first tubular spiral coil; a lower coil including a second planar spiral coil disposed to face the first planar spiral coil and a second tubular spiral coil disposed beneath the second planar spiral coil; a connecting stub configured to connect the upper coil and the lower coil to each other; and a power source configured to supply a power to the upper coil or the lower coil. The first planar spiral coil and the second planar spiral coil generate an electric field and a magnetic field in a resonance state to transfer at least some of the power from the power source to an external wireless power receiving device through the electric field and the magnetic field.
