On the Coding of Chipless Tags
IEEE Journal of Radio Frequency Identification, 2018It is believed that chipless tags, often printable, will play a fundamental role for radio frequency identification technology to replace the currently widely used barcode technology. An application scenario of chipless tags that raises concerns is that the object attached with a chipless tag can be bent and even folded or crumbled. In this case, it is

Chipless RFID tag for IoT applications
2016 IEEE 59th International Midwest Symposium on Circuits and Systems (MWSCAS), 2016Radio Frequency Identification is a rapidly growing technology. Recent advances in wireless technology pave a path for integrating sensors with RFID system. The proposed tag consists of multiple resonators which are used for encoding the data. The tag can also be used for sensing applications by integrating dedicated resonator with the sensor element ...

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 ...

2018 48th European Microwave Conference (EuMC), 2018
In this paper a compact wearable chipless tag is presented. The proposed tag is based on a frequency signature achieved by using a microstrip line loaded by compact resonators slotted in the ground plane. Textile materials have been used for both the substrate and the conductive parts.

Chipless RFID Tag Localization
IEEE Transactions on Microwave Theory and Techniques, 2013A novel localization technique for frequency-domain chipless RF identification (RFID) tag is proposed. A short-duration ultra-wideband impulse radio signal interrogates the tags, and multiple receivers in the interrogation zone capture the backscattered signal from the tags.

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

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.

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.

Compact Polarizer Chipless RFID Tag
2020 4th Australian Microwave Symposium (AMS), 2020A compact one-quarter ring resonator as the building block of the polarizer chipless tags is proposed, and the operating principle and main design parameters are explained. Based on the proposed resonator, a chipless tag with 19 bits of data within 4.6–7.7 GHz frequency band is fabricated, and data capacity of better than 1.55 $\frac{bits}{cm^2}$ is ...
