Circular polarization on depolarizing chipless RFID tags

2016 IEEE Radio and Wireless Symposium (RWS), 2016
We 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 Tags: Co- or Cross-Polar Tag?

2019 IEEE Asia-Pacific Microwave Conference (APMC), 2019
This paper provides a comparison between two types of co- and cross-polar frequency-coded chipless RFID tags considering their electrical parameters. These parameters are the level of radar cross section (RCS), data capacity, rotation sensitivity, and resistant to interferences. A brief description of each parameter is given.

Chipless RFID tag with integrated sensor

2010 IEEE Sensors, 2010
A 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

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.

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.

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.

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

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.

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.
