Comparative assessment of antenna mode and clutter signals in backscattering based UWB-RFID detection (TD(12)04025)

Abstract : Abstract—In modulated backscattering based RFID systems, the "antenna mode" signal received by the reader from the tag can be strongly masked by that originating from the environment (clutter). Although differential detection and appropriate coding may mitigate this problem, it is important to quantitatively evaluate the respective magnitude of both signals. In that work this has been done for a UWB RFID system, intended to operate in the 3-5 GHz band. From 5 ports channel measurements between a set of 4 reader antennas and a tag antenna in various orientations, the antenna mode signal and the clutter signal in the same time window have been determined over a grid of tag positions, providing a distance-dependent statistical model of the signal to clutter power ratio.
