Abstract

Measurement methodology and theoretical equations to RCS and DeltaRCS determination are recalled and the measurement uncertainties are evaluated in this paper. Even if measurement uncertainties are generally not required for RFID, it is important to understand and to be able to determine the measurement uncertainty. Currently, manufacturers and testing laboratories present some results of RFID measurements but never show the associated uncertainty. Yet, seeing the values of the uncertainties, it is clear that they are not negligible.
