IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.In this paper, a hybrid coding method for chipless radio‐frequency identification (RFID) tag with angular orientation is proposed. Frequency‐shift coding is achieved by controlling the size of three complementary split single ring resonators (CSSRR). And on the basis, we add a dimension of polarisation coding, which is achieved through changes in the ...

Degradable and Printed Microstrip Line for Chipless Temperature and Humidity Sensing
Advanced Electronic Materials, Volume 10, Issue 11, November 2024.This study presents a biodegradable printed microstrip line with multi‐resonance for temperature and relative humidity monitoring. Zinc printed on paper encapsulated with beeswax serves as the radio‐frequency transducer. Two resonators at 1.2 and 2 GHz are used to sense temperature and humidity, respectively.

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 ...
