PRINTED CIRCUIT BOARD FOR DUAL MODE ANTENNAS, DUAL MODE ANTENNA AND USER TERMINAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a printed circuit board for dual mode antenna, a dual mode antenna and a user terminal using the same.SOLUTION: A dual mode antenna comprises: an insulative sheet; a loop-shaped near field communication (NFC) coil formed on the insulative sheet; and a wireless power transmission coil formed inside the loop-shaped near field communication (NFC) coil and electrically isolated from the near field communication (NFC) coil, the wireless power transmission coil formed on both surfaces of the insulative sheet and electrically connected to each other via a via hole through the insulative sheet. The wireless power transmission coil formed on both surfaces of the insulative sheet forms loops to reinforce current when viewed from the front.SELECTED DRAWING: Figure 2
