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.

UCR: An unclonable chipless RFID tag

2016 IEEE International Symposium on Hardware Oriented Security and Trust (HOST), 2016
While Radio Frequency Identification (RFID) has become popular for commodity and asset tracking and management, the relatively higher price of RFID tags limits its application in the supply chain of low-cost commodities. Recently, cost-effective chipless RFID tags that do not contain a microchip in the transponder have been gaining more attention from ...

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 ...

High-Resolution Chipless Tag RF Sensor

IEEE Transactions on Microwave Theory and Techniques, 2020
In this article, a new coupled structure based on microwave planar resonators is proposed to demonstrate the capability of ultrahigh quality factor performance using a chipless passive resonator. The platform is based on two passive split-ring resonators (SRRs), one as a reader, and the other one as the tag.

mm-Wave Chipless RFID Tag for Healthcare Applications

2020 XXXIIIrd General Assembly and Scientific Symposium of the International Union of Radio Science, 2020
The work proposes the use of mm-wave chipless tag to be used in healthcare applications. A chipless tag at 24 GHz based on a cross-polarized Van Atta retrodirective array has been designed with the aim to show the practical feasibility of the proposed system.

Chipless RFID Tag-Reader System

2012
In this chapter, we present the integration of the chipless RFID tag and RFID reader presented in the preceding chapters into a system. The implementation constraints in terms of reading range, tag orientation and operating frequency are specified. Specific components of the RFID reader’s digital control section along with the tag ID detection/decoding

Screen printed chipless RFID tags

Proceedings of the 2014 37th International Spring Seminar on Electronics Technology, 2014
Radio Frequency Identification (RFID) is the technology that is used in the daily life. A RFID system consists of RFID tags and readers including many electronic passive and active components. This article deals with design of chipless RFID tags that are screen printed on flexible substrates and do not need any electronic components for their function.

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.

Orientation independent compact chipless RFID tag

2012 IEEE International Conference on RFID-Technologies and Applications (RFID-TA), 2012
A 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.

On the Coding of Chipless Tags

IEEE Journal of Radio Frequency Identification, 2018
It is believed that chipless tags, often printable, will play a fundamental role for radio frequency identification technology to replace the currently widely used barcode technology. An application scenario of chipless tags that raises concerns is that the object attached with a chipless tag can be bent and even folded or crumbled. In this case, it is
