ARRAY ANTENNA FOR SUPPORTING MULTIPLE WIRELESS POWER TRANSMISSIONS, AND WIRELESS POWER TRANSMISSION DEVICE USING SAME

摘要

The present invention relates to an array antenna for supporting multiple wireless power transmissions so as to simultaneously support wireless power transmissions of a magnetic induction method and a magnetic resonance method, and a wireless power transmission device using the same. According to the present invention, the array antenna for supporting multiple wireless power transmissions comprises: a magnetic resonance element unit for transmitting a wireless power signal to the outside by a magnetic resonance method; and a magnetic induction element unit arranged in the vicinity of the magnetic resonance element unit by being spaced from the magnetic resonance element unit, and transmitting a wireless power signal to the outside by a magnetic induction method, thereby simultaneously supporting wireless power transmissions of the magnetic resonance method and the magnetic induction method.
