Design and implementation of transparent multiple-area RFID antennas

Recently, the needs of RFID is increasing due to the convenience of reading without buttery. However, most of legacy passive RFID antennas are in the hard boxes, which have negative appearance. This poor design, limits the use of RFIDs in commercial field, especially in the luxury shops. To solve this problems, we have developed new RFID antenna named ¿IntelliGlass¿ using special thin conductive films on the glass. Our RFID circuits are totally transparent unlike instead of copper line. In this paper, we will show you the new design and implementation of transparent RFID antennas, which has four multiple detecting areas.
