The Implementation of a High-Frequency Radio Frequency Identification System with a Battery-Free Smart Tag for Orientation Monitoring
Electronics, 2017Co-Authors: Tilen Svete, Nejc Suhadolnik, Anton PletersekAbstract:Energy-harvesting passive RFID (radio frequency identification) Tags provide countless possibilities as so-called smart Tags. Smart Tags can communicate with existing RFID readers or interrogators while providing a battery-less platform for internal and external sensors to enrich available information about the environment and smart Tag it. A reduced cost and size as well as an increased lifespan and durability of battery-free smart Tags offer improvements in areas such as transportation and product tracking. Battery-free smart Tags can ideally support arbitrarily complex sensor measurements, but in reality energy limitations can introduce great reductions in operating range and thus application range. In this work, we present an example application of a smart Tag with a passive HF (high-frequency) RFID Tag IC (integrated circuit) and MEMS (micro electro-mechanical structure) sensor. A standard HF RFID reader connected to a PC (personal computer) allowed the RF (radio frequency) field to power and communicate with the smart Tag. A Kalman filter, implemented on a PC, was used to correct and improve the raw sensor data of smart Tag Orientation. Measurement results showed that the MEMS sensor on the smart Tag could be powered for continuous operation and that raw smart Tag Orientation data could be read while in the RF field of a standard HF RFID reader, but at a limited range.

the influence of food composition and Tag Orientation on uhf rf identification
Journal of Food Engineering, 2019Co-Authors: Paolo Barge, Alessandro Biglia, Lorenzo Comba, Davide Ricauda Aimonino, Cristina TortiaAbstract:Abstract Ultra-high frequency (UHF) radio frequency (RF) labelling is considered to be one of the most promising techniques for automatic identification through all food supply chain phases. However, the efficacy of RF IDentification (RFID) systems has proven critical for some food products. In this paper the role of the composition and the temperature of the food product and of the mutual label-reader Orientation on identification performances is investigated. For this purpose, basic food constituents, prepared as solutions (salts, sugars, organic acids and ethanol) at different concentrations and temperatures, were considered and then the identification results were compared to those obtained from whole food products. The results show how the reading performances of UHF RFID systems are influenced by the considered parameters. The reading ranges for the identification of critical food products by UHF RFID systems can be estimated and then improved by considering the composition of the food product directly from the design phase.

Chipless RFID Reading Method Insensitive to Tag Orientation
IEEE Transactions on Antennas and Propagation, 2021Co-Authors: Nicolas Barbot, Olivier Rance, Etienne PerretAbstract:This paper presents a new reading method which is able to decode the backscattered signal of a chipless Tag without any assumption on its Orientation. The method is analytically justified by a model and can be applied to any known scatterers or chipless Tags composed of multiple resonators. The presented approach is based on two orthogonal measurements in copolarization on the reader part and can be optionally combined with time gating. Finally, read range is not reduced with this method since the entire energy of the chipless Tag's antenna mode is exploited by the reader.

toward chipless rfid reading systems independent of Tag Orientation
IEEE Microwave and Wireless Components Letters, 2017Co-Authors: Marco Garbati, Etienne Perret, Romain Siragusa, Christophe HalopeAbstract:A technique for reading chipless radio frequency identification (ID) Tags is proposed. It is based on the cross-polarization principle, and unlike classical approach, the introduced technique allows reading chipless Tag independently of their Orientation. To retrieve the Tag ID, the property of short-time Fourier transform and a polarization diversity approach is exploited. The former is useful to isolate the Tag mode (TM) contribution from the total backscattered signal, notably the presence of clutter form surrounding objects. The latter helps to correctly excite the Tag resonant scatterers and so to maximize the receiving TM energy. The approach has been validated using a laboratory equipment test bench solution, and a cost effective solution.
