NFC antenna module and portable terminal having the same
Provided are an NFC antenna module and a portable terminal having the same, the NFC antenna module having a printed circuit board inserted in a radiation sheet thereof or a radiation field formed on the lower surface and at a side part of the portable terminal, thereby improving the antenna characteristics while solving the problem of mounting space shortage in a small-sized portable terminal. The provided NFC antenna module includes: a printed circuit board; a first radiation sheet, which has a first radiation pattern formed along the outer periphery of a central part and is connected to the printed circuit board; and an electromagnetic wave shielding sheet stacked on the printed circuit board and the first radiation sheet.
1. A portable terminal, comprising:
a portable terminal body;
a lower housing mounted to a lower surface of the portable terminal body;
an NFC antenna module disposed between the portable terminal body and the lower housing; and
a battery pack disposed between the portable terminal body and the lower housing,
wherein the NFC antenna module comprises:
a printed circuit board disposed on a top or a bottom surface of the battery pack; and
a first radiation sheet including a first radiation pattern formed along an outer peripheral portion of a central portion of the first radiation sheet, the first radiation sheet being connected to the printed circuit board,
wherein the NFC antenna module is bent at a portion between the printed circuit board and the first radiation sheet so that the first radiation sheet is disposed on a side surface of the battery pack.
2. The portable terminal of claim 1 , the NFC antenna module further comprising:
a second radiation sheet connected to the printed circuit board that is connected to the first radiation sheet,
wherein the NFC antenna module is bent at a portion between the printed circuit board and the second radiation sheet so that the second radiation sheet is disposed on another side surface of the battery pack.
3. The portable terminal of claim 2 , wherein the second radiation sheet includes:
a terminal connected to an internal circuit of the portable terminal; and
a second radiation pattern connected to the terminal at an end part thereof.
