Chipless frequency signature based RFID transponders
RFID technology is taking the world by storm and there is a requirement for having cheap RFID tags. Chipless transponders offer cheap solutions which can compare with the barcode. We present two types of frequency signature based RFID transponders using multiresonators and fractal antennas. In this article we present the novel chipless RFID concept and simulated and measured results of the chipless tags.
