UHF RFID: Retail Store Performance
IEEE Journal of Radio Frequency Identification, 2022The development of UHF RFID technology has reached significant performance advancement in the last 20 years. Both tags and readers are now improved with better sensitivity levels providing a potential for achieving greater tag read ranges. However, the performances of the technology are also limited by complexity and electromagnetic (EM) properties of ...

A cost-effective integration of passive UHF RFID tags and sensors is still a challenge. In such a field, authors have already proposed a label-type multi-antenna Sensor-Tag, an RFID device accepting as input a generic sensor and allowing the transmission of the measured data towards a standard RFID reader.

A monolithic UHF RFID transceiver for mobile UHF RFID readers
2016 International Conference on Integrated Circuits and Microsystems (ICICM), 2016According to the protocol of ISO/IEC 18000-6C, a monolithic UHF RFID transceiver is designed, in a standard 0.18gm RF CMOS process, in which a receiver, a transmitter and a frequency synthesizer are integrated. The direct-conversion receiver consists of a LNA, down-conversion mixers, DCOCs, LPFs and PGAs.

2016 IEEE International Conference on RFID (RFID), 2016
In this paper a method to test and measure UHF RFID system is presented. The proposed method allows to characterize a RFID UHF tag independently of its antenna. It does not need additional matching circuit and can be used on an automatic prober. Moreover, its main advantages are to determine the characteristics of the chip while the latter is working ...

2015 Loughborough Antennas & Propagation Conference (LAPC), 2015
This paper presents a two-port antenna for a passive RFID tag including separate receiving and transmitting ports for direct connection to a hybrid UHF/UWB RFID transponder chip. The receiving port feed is linearly polarized and narrowband for energy harvesting (from a conventional RFID reader), whereas the transmitting port feeds ultrawideband (UWB ...

The subject of the report was the design and the study of a dual-band micro-strip antenna upon a meta-material substrate, for RFID reader use. The micro-strip antenna was designed for operation at the free UHF bands for RFIDs (866-912 MHz). A meta-material substrate used was of (EBG_ HIGP) type which has the attribute to reflect the incident wave in ...
