Low cost low sampling noise UWB Chipless RFID reader

This paper presents a potentially low cost low sampling noise reader for the Ultra Wideband (UWB) Chipless Radio Frequency Identification (RFID) technology. The reader is designed around the time equivalent approach to reduce its realization cost. A significant effort has been spent for the schematic and layout optimization in order to obtain a very low sampling noise system. This latter aspect is very important to realize a suitable reader for UWB RFID Chipless technology. It is demonstrated that with an accurate design, is possible to realize a low cost equivalent time acquisition system with performances comparable with a high cost real time acquisition system. It is possible acquiring, an UWB impulse of only 70 ps width with high precision.
