Passive Ultrawide Bandwidth RFID

Ultrawide bandwidth (UWB) technology is a promising solution for next generation radiofrequency identification (RFID) systems to overcome most of the main limitations of current RFID systems such as very short operating range, insufficient ranging resolution for accurate localization, sensitivity to interference and scarce multiple access capability. In this paper, the UWB technology is applied to (semi-)passive RFID based on backscatter modulation and the potential performance is investigated in terms of range/data rate trade-off and clutter effect mitigation using experimental data.
