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 ...

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

Circular polarization on depolarizing chipless RFID tags
2016 IEEE Radio and Wireless Symposium (RWS), 2016We propose a new chipless RFID scheme that relies on circularly polarized waves to provide an alignment-independent chipless RFID solution. This approach not only increases the readability of the tags, but also incorporates depolarization capability, reducing the interference effects produced by changes in the environment.

Chipless RFID tag with integrated sensor
2010 IEEE Sensors, 2010A chipless tag based on multiresonators with integrated temperature sensor is presented. The tag consists of a UWB monopole antenna loaded with multiple cascaded spiral EBGs which have a 1∶1 correspondence with data bits. The data bits are encoded into the spectrum hence the tag has a unique spectral signature. The chipless tag is less sensitive to tag

Embedded Singularity Chipless RFID Tags
IEEE Transactions on Antennas and Propagation, 2011Every structure scatters an impulse plane wave in a unique fashion. The structural information of an object can be extracted by analyzing the late-time scattered field as the impulse-response of the structure. The late-time scattered field, which represents the source-free response of the structure, contains a summation of damped sinusoids.

On the Reading of Moving Chipless RFID Tags
2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018RATRASCmovingtagSubmitted. It is demonstrated that the quite common scenario of a moving tag can be advantageously exploited to greatly improve the reliability of the tag detection. The proposed reading procedure is based on the Inverse Synthetic Aperture Radar processing.
