1. A method for manufacturing a tire equipped with a communication module, the method consisting of successively, and in an order required by an architecture of the tire:
laying rubber layers, each rubber layer having a profiled element, and reinforcing elements on a support in order to yield a green tire; and then
vulcanizing the green tire to yield a tire,
wherein the communication module comprises a radio-frequency transponder comprising a primary antenna electrically connected to an electronic chip and inductively coupled to a dipole radiating antenna consisting of a single-strand helical spring,
wherein the tire comprises a radial carcass reinforcement made up of at least one carcass reinforcement layer formed of reinforcing elements inserted between two skim layers of rubber compound, a crown reinforcement, the crown reinforcement radially capped by a tread, the tread being connected to two beads by two sidewalls, the at least one carcass reinforcement layer being anchored in each of the beads by being turned up around a bead wire to form a main part of the at least one carcass reinforcement layer, extending from one bead wire to the other, and a turn-up of the at least one carcass reinforcement layer in each of the beads, the turn-up of the at least one carcass reinforcement layer being separated from the main part of the at least one carcass reinforcement layer by a first layer of rubber compound extending radially externally from the bead wire, a second layer of rubber compound that forms an exterior surface of the tire in a region of the bead, the second layer of rubber compound being intended to come into contact with a rim, and the second layer of rubber compound being, radially toward the outside, in contact with a third layer of rubber compound that forms an exterior surface of the sidewall,
wherein a fourth layer of rubber compound is laid axially between the turn-up of the at least one carcass reinforcement layer and the second and third layers of rubber compound, and
wherein, with the first layer of rubber compound extending radially externally to beyond an end of the turn-up of the at least one carcass reinforcement layer, prior to laying the profiled element of the first layer of rubber compound, a slot is created starting from a surface of the profiled element of the first layer of rubber compound and the communication module is introduced into the slot, placed radially on the outside relative to the end of the turn-up of the at least one carcass reinforcement layer, and encapsulated within the profiled element of the first layer of rubber compound.
