Designing UHF RFID tag antennas with Barcode shape for dual‐technology identification

IET Microwaves, Antennas &Propagation, Volume 16, Issue 12, Page 733-742, October 2022., 2022
Abstract In this paper, a novel methodology to design Ultra High Frequency Radio‐Frequency IDentification (UHF RFID) tag antennas with Barcode layout is proposed with the challenging goal of “fusing” both technologies in a single device. Specifically, after a brief recall of the well‐known barcode standard, a procedure to design meandered barcode ...

Frequency generator demonstration using half mode Substrate Integrated Waveguide (SIW) structures for chipless Radio Frequency Identification (RFID) reader

IET Circuits, Devices &Systems, Volume 16, Issue 5, Page 410-418, August 2022., 2022
Abstract A frequency generator based on the forward coupler principle is proposed. The proposed design, intended for high‐frequency applications, uses Half‐Mode Substrate Integrated Waveguide structure to realise the forward coupler. It thus achieves compactness, requiring approximately half the area compared to Substrate Integrated Waveguide ...

Influence of Dielectric Loss on RF Performance of Microstrip Multi‐Resonant Circuits

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
Nowadays, fabric‐based antennas, resonators, and sensors are attracting significant attention due to their excellent comfortability and flexibility compared with the rigid commercial printed circuit boards (PCBs). Both the dielectric constant (εr) and dielectric loss tangent (tanδ) of substrate materials have a great influence on their frequency ...
