Abstract :
A fully functional passive RFID-tag has been integrated on a modern standard CMOS process. This paper focuses on the localization capability of the RFID-transponder. First the principle of the localization approach used is described. After that the principle is verified by an experimental setup. The measured distance between the FMCW reader and the RFID-tag showed a standard deviation of about 20 cm.
