Multi‐resonator application on size reduction for retransmission‐based chipless RFID tag

Electronics Letters, Volume 57, Issue 1, Page 26-29, January 2021., 2021
Abstract Here, a ‘truncated C’‐shaped planar coupled line resonator for UWB retransmission‐based chipless RFID has been presented. The resonator is small compared to other existing resonators in the retransmission‐based chipless RFID family. Two different coded multi‐resonator prototype tags have been designed and validated with newly designed planar ...

Indoor Visible Light Applications for Communication, Positioning, and Security

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
With the rapid development of smart cities, white light‐emitting diodes (LEDs) are widely used in indoor lighting due to their characteristics of energy‐saving, long lifetimes, and low cost. At the same time, the high‐frequency modulated LEDs allow visible light to be used for indoor communications, positioning, and security. Visible light applications

Industry 4.0‐Oriented Chipless RFID Backscatter Signal Variable Polarization Amplitude Deep Learning Coding

Wireless Communications and Mobile Computing, Volume 2021, Issue 1, 2021., 2021
Due to the weak network security protection capabilities of control system network protocols under Industry 4.0, the research on industrial control network intrusion detection is still in its infancy. This article discussed and researched the intrusion prevention technology of industrial control networks based on deep learning.

“Unconventionally Shaped” Antenna Design for UHF RFID Tags

International Journal of Antennas and Propagation, Volume 2021, Issue 1, 2021., 2021
UHF RFID tags need to be attached or embedded into various objects. Unlike traditional free‐standing antennas, UHF antenna shapes and form factors may vary significantly. There have been no systematic methods that facilitate the design practice of antenna with unconventional shapes. In this paper, using the geometries of 26 English letters (in capital)

Compact slot-based chipless RFID tag [PDF]

2014 IEEE RFID Technology and Applications Conference (RFID-TA), 2014
We present a fully printable, planar, orientation independent, single layer, chipless RFID tag. The tag consists of a circular patch with multiple discretized circular slot resonators nested in it. This design reduces the total size of the tag since the discrete circular slot resonators resonate at a lower frequency than perfect circular resonators for
