Ultra Wideband (UWB) modulated backscattering (MBS) passive Radio-Frequency IDentification (RFID) systems provide a promising solution to overcome many limitations of current narrowband RFID devices. This work addresses the performance of such systems from the point of view of the radio channel between the readers and the tags. Such systems will likely combine several readers, in order to provide...
We consider a system of 4 Ultra Wide Band (UWB) readers, intended for the detection and localization of tags operating in backscattering. Although Line of Sight (LOS) propagation is the most significant propagation mechanism for the successful operation of the system, several detrimental effects must be taken into account in practice, as they very much impact the overall performance. In this work,...
ultra wide band semi-passive RFID based on a backscattering principle promise an excellent trade-off in terms of cost, range and localization capability. However, this trade-off will be deeply impacted by the characteristics of the backscattering, which involves both the propagation channel and the tag antenna mode behaviour. This work addresses the joint modelling of both, starting from rigorous...
