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

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‐shaped UHF RFID tags is introduced and discussed leveraging on electromagnetic evidence. The main steps of the proposed method are described by highlighting the constraints inherited by both the adopted technologies, as well as the useful opportunities to automatise the entire antenna design process after a preliminary simulation campaign through a full‐wave simulator. Different RFID‐Barcode tag antennas are designed, manufactured, and characterised in terms of maximum reading range and tag sensitivity. Obtained results demonstrate the validity of the proposed approach.

A Hybrid Anti-Collision Protocol Based on Frequency Division Multiple Access (FDMA) and Time Division Multiple Access (TDMA) for Radio Frequency Identification (RFID) Readers

“…RFID, short for Radio Frequency Identification, is a method for remote data storage and collection using metal tags known as "RFID tags". These tags respond to radio waves, enabling wireless transmission of information and showing promise in potentially replacing traditional barcodes [1]. Despite its efficiency, RFID adoption raises significant ethical and privacy concerns.…”
