The present invention relates to a near field communications (NFC) antenna using a wire. The invention includes: a wire part with more than one wire; an antenna which combines more than one wire parts in various patterns and is connected to a flexible printed circuit board with spot-welding on one side of the wire parts; and an antenna impeded sheet in which the antenna is mounted with an ultrasound impeded method, and forms fixing grooves to fix the flexible printed circuit board on the side of the wire. The present invention can prevent declining of the performance of the antenna by the resistance included in the wire, by widening the cross-section area of the antenna through allowing the wire part formed of multiple rows of wires to transmit signals using the antenna formed of multiple rows. Further, the invention can install the antenna in a narrow space by minimizing the space of the antenna through the separation of the wire part formed of multiple rows of wires with regular intervals, while separating the wires with regular intervals. The invention prevents shorts between the wire parts by separating the wire parts. Further, the invention can exchange the signals smoothly by eliminating the cause of communications failure and reducing operation distance from the signal loss of the signal bandwidth of which the user wants, while the resonant frequency is changed due to change of the inductance based on the characteristics of wire and wire parts. |
