Robust Detection of A Moving Chipless RFID Tag

2020
The chipless RFID tag can be attached to a mobile object such as a product on a conveyor belt, an item dropping into a shopping trolley basket, a human or an animal in which the information is more difficult to detect than in the case where the tag is attached to a stationary object.

Improved chipless tag based on multifilters

Microwave and Optical Technology Letters, 2017
AbstractIn this study, a novel compact chipless RFID transponder is presented. The coding information is based on spectral signature using three types of multiresonator: spiral, slot, and U‐shaped defected ground structure (DGS). Each resonator can be seen as a band‐stop filter which contributes to a particular resonance frequency.

Embedded Singularity Chipless RFID Tags

IEEE Transactions on Antennas and Propagation, 2011
Every 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.

High-density compact chipless RFID tag for item-level tagging

2018 International Applied Computational Electromagnetics Society Symposium (ACES), 2018
This paper presents 36-bit compact passive chipless RFID tag. The bowtie shape based tag structure is loaded with 36 slots. The tag is capable of yielding high data density. The overall tag dimension is 27mm × 26mm. The tag structure is optimized and analyzed for three different substrates, i.e., FR-4, Taconic TLX-0, and Rogers RT5880. Each loaded slot

Identification of Chipless RFID Tags in the Reader

2014
The signal received by the antenna includes the scattered signal from the chipless RFID tag located in the reader area, reflections from background objects (clutter), and noise. Therefore, the detection process is a challenging aspect in the design of chipless RFID systems.

On the Reading of Moving Chipless RFID Tags

2018 2nd URSI Atlantic Radio Science Meeting (AT-RASC), 2018
RATRASCmovingtagSubmitted. 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.

Novel chipless tag with electromagnetic code

The 2nd Middle East Conference on Antennas and Propagation, 2012
This paper presents a new radio frequency identification (RFID) chipless tag operating in the frequency span 4-7 GHz. The tag consists of triangle microstrip filter. The bits are encoded into the spectrum hence the tag has a unique spectral signature. The tag is less sensitive to tag orientation and has smaller size.

Chipless RFID tag for light sensing

2014 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2014
A 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 ...

Multilayer Chipless THz Tag for Identification

2025 International Conference on Mobile and Miniaturized Terahertz Systems (ICMMTS)
Identification of an object or a class of objects is a more and more appealing goal in the vast realm of the Internet of Everything (IoE) paradigm. This work proposes a multilayer dielectric structure that can encode information in its frequency response to a probing plane wave.
