In the renewable energy sector, the management of protective equipment (PPE and collective safety systems) is a crucial priority to reduce workplace risks and ensure the safety of operations. This article presents the design and optimization of a novel UHF RFID tag operating at 868 MHz, featuring an original structure inspired by a wind turbine shape. This tag is specifically designed to be integrated into industrial safety helmets made of polycarbonate, a material characterized by a dielectric constant εr = 2.9 and a loss tangent tanδ = 0.01. The tag aims to enhance equipment tracking and traceability. The antenna is adapted to an Alien H4 UHF RFID chip, which has an internal impedance of Z = 23.37 - j203.3 Ω at the chosen frequency, ensuring optimal power transfer. Simulation results demonstrate that the tag offers high readability and efficiency while respecting the mechanical and dielectric properties of polycarbonate. This study highlights the potential of innovative UHF RFID tag designs for tracking safety equipment in industrial environments, offering a robust solution to improve workplace safety and operational efficiency.
