Title
(EN) TYRE COMPRISING A RADIOFREQUENCY TRANSPONDER
(FR) PNEUMATIQUE EQUIPE D'UN TRANSPONDEUR RADIOFREQUENCE
Abstract
(EN)
The invention relates to a tyre comprising a transponder, having: - a crown which comprises a crown reinforcement with an axial end at each edge, joined at each of its axial ends to a bead, which has an inner end, by a sidewall; - a carcass reinforcement layer made up of parallel metal reinforcements anchored in each bead around a bead core so as to form a main part and a turn-up; - the transponder comprising a dipole antenna consisting of a spring defined by a pitch P and a diameter D, the length of which defines a longitudinal axis, characterised in that the ratio between the pitch (P1) and the diameter (D1) for a loop of a first zone of the spring is greater than 0.8, and in that the transponder is positioned axially outside in relation to an inner end of the bead and radially between the upper end of the bead core and the axial end of the crown reinforcement.
