HYBRID COIL ANTENNA AND SYSTEM FOR WIRELESS POWER TRANSMISSION USING THE SAME

摘要

PURPOSE: A hybrid coil antenna and a wireless power transmission system are provided to be manufactured in a helical shape, thereby reducing the diameter of an antenna structure. CONSTITUTION: A spiral coil unit (110) is formed in a spiral shape. The spiral coil unit has a constant diameter on a virtual plane. A helical coil unit (120) is formed in a helical shape. The spiral coil unit and the helical coil unit are rotated in the same rotation direction. The spiral coil unit and the helical coil unit are continuously connected to each other.
