Contribution to the development of UWB chipless RFID reader based on IR-UWB approach

Abstract : The RFID technology is in full development, and is intended to substitute barcode in the next future. Between all the RFID families, the UWB chipless RFID technology is a major topic nowadays. With this thesis we focus on development of UWB chipless RFID readers, based on IR-UWB approach.The international regulations that limit the UWB emission are taken into consideration, and two reader prototypes developed. The first was as a concept car, and therefore used as proof of concept. The second version represents a full optimized reader in all the key aspects. Between them, the reading precision, through sampling noise reduction, the reading time, and cost effectiveness. As part of reader development, a low noise and low cost UWB pulse generator prototype was realized, along with UWB antennas, and RF front-end boards. As prospective, a reading technique based on polarization diversity is shown, with the aim of reading cross-polarized tags independently from their orientation. This approach is valuable because does not give any constraint at the tag design level
