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.

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
