Abstract
Contactless label designed to ensure the traceability of an object featuring a microcircuit () and a Y-shaped dipole antenna connected to the microcircuit, which contains information necessary for tracing the object, which can be read with a reader through the exchange of ultra high frequency (UHF) electromagnetic waves. The antenna includes three main wires, a first main wire (), a second main wire () forming a first dipole with the first main wire and a third main wire () forming a second dipole with the first main wire. The angle between the first and second main wires is equal to the angle between the first and the third main wires and the angle between the second main wire and the third main wire is between 60° and 180°. Each of the main wires features a secondary wire (, or) at its end perpendicular to the main wire.
