Study of Ultra Wide Band Modulated Backscattering Based RFID Systems

Abstract : In the recent years, the idea of the Internet of Things, that is a pervasive presence of electronics devices embedded in every-day objects, is facing a rapid adoption and will create a new era in the Internet scenario. Among all the technologies, radio frequency identification (RFID) seems one of the most promising. In addition, when tag cost, size and power consumption become stringent requirements, (semi-) passive solutions based on the modulation of the backscatter signal represent a good choice. Thus, this work was developed with the intent to study UWB RFID systems based on the modulation of the backscattered signal considering different related issues. The European Project SELECT gave the motivation to investigate the combination of UWB and RFID technologies, which are expected together to overcome many limitations of current narrowband RFID devices. The consciousness that, before the design of proper system architectures for backscatter communication, it was fundamental to understand the basic EM mechanisms underlying the interaction between readers and tags, was reflected in a wide investigation ranging from EM characterization of backscatter links to the definition and design of signal structures and transmission schemes. This dual need motivated a joint french-italian agreement between two laboratories for the supervision of the thesis. In particular, in the course of the work carried out in France, the analysis of the tag backscattering has been analyzed in several ways, both in ideal and real conditions. The results and competences were then exploited in Italy, in order to study an architecture able to ensure a reliable communication between reader and tag.
