A High‐Density L‐Shaped Backscattering Chipless Tag for RFID Bistatic Systems

International Journal of Antennas and Propagation, Volume 2018, Issue 1, 2018., 2018
Chipless radiofrequency identification (RFID) technology is very promising for sensing, identification, and tracking for future Internet of Things (IoT) systems and applications. In this paper, we propose and demonstrate a compact 18‐bit, dual polarized chipless RFID tag.

A Novel L‐Shape Ultra Wideband Chipless Radio‐Frequency Identification Tag

International Journal of Antennas and Propagation, Volume 2017, Issue 1, 2017., 2017
A novel compact dual‐polarized‐spectral‐signature‐based chipless radio‐frequency identification (RFID) tag is presented. Specifically, an L‐shape resonator‐based structure is optimized to have different spectral signatures in both horizontal and vertical polarizations, in order to double the encoding capacity.

Design of Compact Trapezoidal Bow‐Tie Chipless RFID Tag

International Journal of Antennas and Propagation, Volume 2015, Issue 1, 2015., 2015
This paper presents a novel compact design of a low cost fully printable slot‐loaded bowtie chipless RFID tag. The tag consists of two trapezoidal metallic patches loaded with multiple slot resonators. Slots with similar size or adjacent frequencies are loaded alternately on two bow‐tie patches to double the number of data bits within the UWB frequency

Transponder Designs for Harmonic Radar Applications

International Journal of Antennas and Propagation, Volume 2015, Issue 1, 2015., 2015
This work presents a review on the concept of harmonic or secondary radar, where a tag or transponder is used to respond at a harmonic multiple of the incoming interrogation signal. In harmonic radar, the tag is called a harmonic transponder and the necessary frequency multiplication is implemented using a nonlinear element, such as a Schottky diode ...

Hybrid model chipless RFID tags based on the integration of filter theory and multi-resonator circuit

Pamukkale University Journal of Engineering Sciences
In this paper, a hybrid model chipless radio frequency identification (RFID) tag is introduced. It is constructed by using multi -resonator circuit with a bandstop filter simultaneously. Bandstop filter section is conventionally designed by quarter -wave open -circuited stubs, while the multi -resonator circuit is developed by coupling dual -band ...

Hybrid DCNN-Enabled Depolarizing Chipless RFID: Improving Tag Detection Across Varying Lossy Surfaces and Shapes

IEEE Journal of Radio Frequency Identification
This paper presents a comprehensive design and implementation approach for robust detection of depolarizing chipless RFID (CRFID) tags. Depolarizing tags are advantageous compared to co-polar CRFID tags due to their improved performance on RF-lossy materials.
