This paper address the problematic of estimating the performance of chipless RFID systems operating in the UWB band from 3.1GHz to 10.6GHz. For this purpose, a model which takes into account chipless tags' characteristics such as RCS and quality factor is proposed to better estimate the theoretical detection distances. Chart showing theoretical detection distances as a function of the frequency and for various RCS levels are derivate from radar equation according to the radiated emission limit set by transmit power regulation authorities. Detection ranges are estimated according to two different approaches, the continuous wave based radar technique, and the impulse radio based radar technique. Index Terms-chipless RFID, UWB, read range, radar.
