Ranging RFID Tags With Ultrasound
IEEE Sensors Journal, 2018Indoor localization and tracking of persons and assets with centimeter-level accuracy for inventory, security, medical monitoring, and training, as well as gesture interfaces for domotics, is highly desirable in the framework of the emerging IoT paradigm. Low cost, tiny, battery, or batteryless operated position sensors are required.

Surface acoustic wave (SAW) radio-frequency identification (RFID) tags are soon expected to be produced in very high volumes. The size and cost of a SAW RFID tag will be key parameters for many applications. Therefore, it is of primary importance to reduce the chip size.

One key element of a chipless RFID system is the tag. Since it is chipless, it acts both as the scatterer and encoder. As the scatterer, it needs to reradiate the incident field as much as possible in order to maximize signal-to-noise ratio (SNR) in the reader. As the encoder, it needs to encode a high density of data on the backscattered signal. There

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.

RFID Tag Vulnerabilities in RFID Systems
2008More than half a century after its inception, radiofrequency identification (RFID) technologies are finally living up to their long promised capabilities. They are being rewarded with pervasive deployments in closed loop applications and the initial deployments in the even more pervasive open loop supply chain management applications.

Recently Radio Frequency IDentiflcation (RFID) systems are used in many applications. However an individual identification scheme using RFID tags has a serious problem that if there are many tags within the reader's operation range, then the reader can not determine a genuine tag of a user to be authenticated, the identification protocol is executed ...

Organic RFID tags are increasingly gaining credibility as a possible low-cost barcode replacement for product identification. This will only happen if organic RFID tags can operate in the frequency range defined by well-accepted EPC standards. This chapter evaluates the performance of existing organic RFID demonstrators and confirms that, based on lab ...

RFID reader localization using passive RFID tags
2009 Asia Pacific Microwave Conference, 2009This paper describes an indoor wireless localization method of an RFID reader using passive tags placed at known locations. The reader location is estimated using the received signal strength indication (RSSI) and trilateration. However, in an indoor wireless environment, the RSSI undergoes fading due the presence of unavoidable scatterers.

This communication covers the design and optimization of antennas for RFID tags at UHF and microwave frequencies. Such design will focus on the specific characteristics of RFID applications such as back-scattering mode, variability of substrates and low cost constraints. The introduction includes a short history of RFID development.

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 ...
