Abstract:
1. A near field communication antenna device of a mobile terminal, the device comprising: a window including a display region for transmitting an image displayed by a display and a black mark region formed around the display region; a multi-layer Flexible Printed Circuit Board (FPCB) on which a plurality of layers are laminated, the multi-layer FPCB being disposed on a lower side of the black mark region of the window; a spiral loop-shaped antenna pattern in which conductive lines are formed on respective layers of the multi-layer FPCB and are connected to each other; and a closed loop FPCB having a closed loop antenna pattern that is electrically disconnected from the antenna pattern, the closed loop FPCB being laminated so as to be at least one of (i) between at least two layers of the plurality of layers of the multi-layer FPCB, (ii) on an upper side of the multi-layer FPCB, and (iii) on a lower side of the multi-layer FPCB.
