A tire fitted with a transponder comprises: a crown comprising a crown reinforcement having an axial end at each of its edges, connected at each of its axial ends by a sidewall to a bead having an interior end; a carcass reinforcement layer formed of parallel reinforcers, which is anchored in each bead around a bead wire to form a main part and a turn-up; and the transponder comprising a dipole antenna consisting of a spring defined by a pitch P and a diameter D. A ratio between the pitch (P1) and the diameter (D1) for a loop of a first region of the spring is greater than 0.8, and the transponder is situated axially on the outside of an interior end of the bead and radially between the upper end of the bead wire and the axial end of the crown reinforcement.
