A tire casing is equipped with a radiofrequency transponder and includes a crown, two sidewalls and two beads revolving around a reference axis, first threads forming outward segments and return segments that are arranged adjacently, aligned circumferentially, anchored in the two beads with, in each bead, loops in each case linking an outward segment to a return segment and, in each bead, means for anchoring the first threads, comprising second threads oriented circumferentially axially bordering the first threads and forming at least one spiral, the first threads forming at least one circumferential alignment defining the carcass ply that separates said tire casing into two zones, inside and outside with respect to this carcass ply. The radiofrequency transponder comprises at least one electronic chip and a radiating radiocommunication antenna and is positioned radially externally in relation to the at least one spiral, characterized in that the radiofrequency transponder comprises a primary antenna electrically connected to the electronic chip, in that the primary antenna is electromagnetically coupled to the radiating antenna, and in that the radiating antenna is formed by a single-strand helical spring defining a first longitudinal axis.
