An RFID tag using conductive yarn is provided to implement RFID tags with the conductive yarn or textiles made of the conductive yarn. An RFID tag(100) using conductive yarn comprises the followings: a tag antenna(2) consisting of the first and second arms(2a, 2b) which are made of one or more conductive yarns; a matching closed circuit loop(2c) made of one or more conductive yarns; and an RFID chip(4) which is positioned in a feeding point gap between the first and second arms to be connected with each arm. By adjusting antenna parameters such as the length(ant_l) and width(ant_w) of the first and second arms, antenna impedance is matched so as to be the conjugate complex number of the chip impedance of the RFID chip. |
