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 ...

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.

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 ...

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.

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

Simple Chipless RFID Tag Configurations
2018 IEEE Asia-Pacific Conference on Antennas and Propagation (APCAP), 2018Two unique configurations of chipless RFID tag are reported in this paper. They consist of integrated Lresonators and cross polarized transmitting and receiving circular patch antennas. The validations of the proposed designs have been carried out using 8-bit data encoded tags, for the frequency band of 3.3–5.8 GHz, and microstrip circular antenna ...

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
