<p>The invention concerns a non-contact label designed to ensure traceability of an object comprising essentially a microcircuit (16) and a Y-shaped antenna connected to the microcircuit which contains data required for the traceability of the object, readable from a reader through ultra high frequency (UHF) electromagnetic exchange. The antenna is of the dipole consisting of three main wires, a first main wire (10), a second main wire (12) forming a first dipole with the first main wire and a third main wire (14) 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 third main wires, and the angle between the second main wire and the third main wire ranges between 60° and 180°. Each of the main wires comprises at its end a secondary wire (24, 26 or 28) perpendicular to the main wire.</p> |
