Chipless radio frequency identification provides a huge potential for applications with extreme environmental conditions. The low data capacities and the printability on film or paper, prevent the use of state-of-the-art realizations in scenarios with extreme temperature. Hence, we introduce a novel chipless RFID tag that overcomes these problems. Due to a polarimetric and image base data encoding,...
Localization of vehicles in industrial environments is a challenging task due to the high demands on the radar system because of harsh environmental conditions and strong multipath propagation. Chipless radio identification (RFID) is well suited for this type of task due to its low-cost production and extreme robustness against environmental influences. Furthermore, RFID transponders based on time...
This paper provides a fundamental analysis of the maximum possible information content and reading range of chipless time-domain reflectometry (TDR) radio frequency identification (RFID). Bits encoded on a tag as well as bits that can be decoded by the reader need to be considered to estimate the information content on a tag. This needs an approach that deals with the entire RFID system. Factors such...
This paper presents a wireless positioning concept based on time domain reflectometry (TDR) chipless radio frequency identification (RFID) landmarks. The concept is intended for vehicle or mobile robot localization in indoor scenarios. Chipless RFID tags are well suited to serve as uniquely recognizable landmarks in industrial or warehouse scenarios due to their unlimited life cycle and robustness...
This paper presents a low-cost, low-complexity FMCW-based ultra-wideband (UWB) chipless time domain reflectometry (TDR) radio frequency identification (RFID) system, which is suitable for implementing higher order modulation schemes. Higher order modulation significantly increases the information content in chipless RFID. The applicability of phase-shift keying (PSK) and pulse-position modulation...
