Abstract
Disclosed herein are a flexible printed circuit board for dual mode antennas, a dual mode antenna and a user device using the same. The flexible printed circuit board for dual mode antennas includes a first loop-shaped coil formed at one main surface of an insulative sheet and a second loop-shaped coil formed inside the loop of the first coil.
Claims16
A dual mode antenna comprising:
- an insulative sheet;
- a loop-shaped NFC coil formed on the insulative sheet;
- a wireless power transmission coil formed inside the loop of the NFC coil and electrically isolated from the NFC coil, the wireless power transmission coil formed on opposite surfaces of the insulative sheet and electrically connected from each other through a via hole of the insulative sheet;
- a pair of NFC coil connection terminals electrically connected to both ends of the NFC coil, respectively;
- a pair of wireless power transmission (W/C) coil connection terminals electrically connected to both ends of the wireless power transmission coil, respectively;
- and
- a pair of extension patterns electrically connecting the pair of W/C coil connection terminals and both ends of the wireless power transmission coil,
- wherein the wireless power transmission coil formed on opposite surfaces of the insulative sheet form loops to reinforce current flowing in the wireless power transmission coil when viewed at the front of the insulative sheet, and
- wherein the pair of extension patterns and the NFC coil are formed on different surfaces of the insulative sheet from each other.
