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 ...

Performance Enhancements of Fully Inkjet‐Printing Technology for Antenna‐in‐Package and Substrate Integrated Waveguides

International Journal of Antennas and Propagation, Volume 2022, Issue 1, 2022., 2022
A fully inkjet‐printing technology is applied to antenna‐in‐package (AiP) and substrate integrated waveguide (SIW) to enhance the performance of three components, including via holes, wire bonding, and flexible antenna arrays. First of all, earlier studies utilize shorting pins for the conductive pathway in high‐density AiP and SIW, but this requires ...

Corner reflector tag with RCS frequency coding by dielectric resonators

IET Microwaves, Antennas &Propagation, Volume 15, Issue 6, Page 560-570, 20 May 2021., 2021
Abstract For a novel indoor‐localization system, chipless tags with high retro‐directive radar cross‐section (RCS) under wide‐angle incidence are required as fixed landmarks. Tags based on dielectric resonators (DRs) were proposed to provide identification by resonance frequency coding.
