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

Improved detection scheme for chipless RFIDs using prolate spheroidal wave function-based noise filtering [PDF]
, 2011 A novel, highly sensitive scheme to detect the resonance peaks in the spectrum of chipless RFID signals is presented. The detection is based on finding the zeros in the derivative of the group delay of the received signal.

“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)

An Inkjet Printed Chipless RFID Sensor for Wireless Humidity Monitoring [PDF]
, 2017 A novel chipless RFID humidity sensor based on a finite Artificial Impedance Surface (AIS) is presented. The unit cell of the AIS is composed of three concentric loops thus obtaining three deep and high Q nulls in the electromagnetic response of the tag.

Time-domain-signature chipless RFID tags : near-field chipless-RFID systems with high data capacity [PDF]
IEEE Microwave Magazine, 2019 Chipless RF identification (RFID) technology has emerged as an alternative to RFID systems that have tags equipped with silicon integrated circuits (ICs), or chips [1]-[12]. The main advantage of chipless RFID systems over their chipped counterparts is the lower cost of the tags, which results from the fact that the ID code is contained in a printed ...
