摘要： A radiofrequency communication module or semi-finished product able to be integrated into the structure of a tire comprises a radiofrequency transponder embedded in a rubber blend and comprising an electronic chip and a radiating antenna that is able to communicate with a radiofrequency reader. The radiofrequency transponder in addition comprises a primary antenna that is electrically connected to the electronic chip, the primary antenna is electromagnetically coupled to the radiating antenna, the radiating antenna consists of a single-strand helical spring, and the radiating antenna has a core made of steel coated with a metal exterior adhesion layer for adhesion to the rubber blend that surrounds it.

摘要： A passive radiofrequency transponder comprises a radiating dipole antenna consisting of a single-strand helical spring having an axis, a median plane, a pitch and a diameter for a given wire diameter, and an electronic portion located inside the radiating antenna. The electronic portion comprises an electronic chip electrically connected to a primary antenna that is electromagnetically coupled to the radiating antenna. The primary antenna has an axis parallel to the axis of the radiating antenna and a median plane superposed with the median plane of the radiating antenna. The primary antenna is circumscribed by a cylinder the diameter of which is larger than one third of the inside diameter of the radiating antenna. The radiofrequency transponder is characterized in that, in a first region of the radiating antenna, in which the latter is not located plumb with the electronic portion, the first helix pitch of the radiating antenna is larger than the second helix pitch of the radiating antenna that does not form part of this first region.

摘要： A tire casing is equipped with a radiofrequency transponder and includes a crown, two sidewalls and two beads, each bead including at least one annular bead wire revolving around a reference axis, at least one annular carcass ply, coaxial with the reference axis anchored in the beads separating the tire casing into two zones, inside and outside the carcass ply. The radiofrequency transponder comprises at least one electronic chip and a radiating radiocommunication antenna and is positioned radially externally in relation to said bead wire, 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 strand helical spring defining a first longitudinal axis.

摘要： 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.
