ANTENNA FOR NEAR FIELD COMMUNICATION, NEAR FIELD COMMUNICATION TERMINAL HAVING THE SAME, RADIO FREQUENCY ANTENNA, AND IC CARD HAVING THE SAME

摘要

An antenna for NFC(Near Field Communication), an NFC terminal having the same, an RF(Radio Frequency) antenna, and an IC(Integrated Chip) card having the same are provided to improve a receiving range and receiving safety by reducing loss of a signal and power transmitted from an active antenna. An antenna for NFC includes a first layer, a second layer, a third layer, a fourth layer, and at least one capacitor(7). An antenna coil which is wound by a plurality of wires is arranged on the same plane with the first layer substantially. The second layer is for ground shielding. The third layer is made of a plastic sheet. A receiving range extension coil which is separated from the antenna coil and forms an independent closed loop is arranged on the fourth layer. The capacitor is electrically connected to the receiving range extension coil. The capacitor forms a closed loop with the receiving range extension coil.
