mm-Wave Chipless RFID Tag for Healthcare Applications
2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020The work proposes the use of mm-wave chipless tag to be used in healthcare applications. A chipless tag at 24 GHz based on a cross-polarized Van Atta retrodirective array has been designed with the aim to show the practical feasibility of the proposed system.

UCR: An unclonable chipless RFID tag
2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2016While Radio Frequency Identification (RFID) has become popular for commodity and asset tracking and management, the relatively higher price of RFID tags limits its application in the supply chain of low-cost commodities. Recently, cost-effective chipless RFID tags that do not contain a microchip in the transponder have been gaining more attention from ...

Chipless RFID tag for light sensing
2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014A fully passive chipless RFID tag with light sensing capabilities is presented for low-cost, maintenance-free applications. This paper describes the steps towards developing a prototype of passive light sensor using off the shelf photoresistors. Results show a single microwave resonator has 60 MHz frequency shift and 7.5 dB power variation for 0 to ...

Orientation independent compact chipless RFID tag
2012 IEEE International Conference on RFID-Technologies and Applications (RFID-TA), 2012A design concept of a compact printable orientation independent chipless radio frequency identification tag is presented with near-field and far-field reading techniques. The tag consists of a circular patch loaded with multiple slot ring resonators and it has the advantage to be read from any orientation with the reader due to its symmetric structure.

Chipless RFID Tags: Co- or Cross-Polar Tag?
2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019This paper provides a comparison between two types of co- and cross-polar frequency-coded chipless RFID tags considering their electrical parameters. These parameters are the level of radar cross section (RCS), data capacity, rotation sensitivity, and resistant to interferences. A brief description of each parameter is given.

Chipless RFID Tag-Reader System
2012In this chapter, we present the integration of the chipless RFID tag and RFID reader presented in the preceding chapters into a system. The implementation constraints in terms of reading range, tag orientation and operating frequency are specified. Specific components of the RFID reader’s digital control section along with the tag ID detection/decoding

Screen printed chipless RFID tags
Proceedings of the 2014 37th International Spring Seminar on Electronics Technology, 2014Radio Frequency Identification (RFID) is the technology that is used in the daily life. A RFID system consists of RFID tags and readers including many electronic passive and active components. This article deals with design of chipless RFID tags that are screen printed on flexible substrates and do not need any electronic components for their function.

UWB chipless tag RFID reader design
2010 IEEE International Conference on RFID-Technology and Applications, 2010A chipless tag RFID reader is presented for short range applications. The RFID reader is comprised of a digital section, RF section and cross-polarized reader horn antennas. The reader horn antennas are used to transmit and receive data to and from the chipless tags respectively.

A narrowband chipless multiresonator tag for UHF RFID
Journal of Electromagnetic Waves and Applications, 2013In this work, a narrowband fully passive printable RFID chipless tag, working in the UHF band, is presented. The tag consists of two cross-polarized transmitting and receiving microstrip broadband circular monopole antennas, loaded with multiple cascaded resonators, each one unambiguously corresponding to one data bit.
