NEAR FIELD COMMUNICATION ANTENNA

摘要

An antenna of a near field wireless communication device is provided. The antenna may include: a source coil pattern formed on one surface of a flexible printed circuit board (FPCB) and formed with a first conductive line between a first antenna port and a second antenna port; a resonance coil pattern formed with a second conductive line, which electrically separates from the source coil pattern; and a capacitor pattern electrically connected to the second conductive line, wherein one terminal of the capacitor pattern is connected to a first terminal of the second conductive line and the other terminal of the capacitor pattern is connected to a second terminal of the second conductive line through a third conductive line formed on the other surface of the FPCB.
