Tire comprising a passive transponder and method for reading the data

A pneumatic tire having a toroidal form, having axial, radial, and circumferential directions with respect to a tire center, and having a radially inner surface and a radially outer surface, the pneumatic tire comprising:

• a crown;
• two sidewalls extending from the crown;
• two beads respectively connected to the sidewalls, each bead including an annular bead core, the beads encircling a reference axis passing axially through the tire center, the reference axis being an axis of rotation of the pneumatic tire;
• a carcass ply having a toroidal form;
• an inner liner;
• for each bead, a protector having a toroidal form, the protector being made from at least one elastomeric blend and having a main portion located radially inward of the bead core of the corresponding bead, the carcass ply, and the inner liner, the protector including a first end located axially inward and radially outward of the main portion, and the protector including a second end located axially inward and radially inward of the first end, the second end forming a bead toe;
• and
• a passive transponder that includes an electronic chip and at least one metal strand forming a radiating antenna that is structured to enable electrical coupling to the electronic chip,
• wherein a longitudinal axis of the passive transponder is positioned substantially perpendicular to threads of the carcass ply,
• wherein the passive transponder is embedded in an electrically insulating elastomeric blend forming a patch,
• wherein the patch has, on a periphery thereof, a first face located axially outward with respect to the tire center, and a second face located axially inward with respect to the tire center, the first and second faces being substantially perpendicular to the reference axis,
• wherein the patch has, on the periphery thereof, a first end located radially inward relative to the reference axis, and a second end located radially outward relative to the reference axis, the first end and the second end defining a minimum distance and a maximum distance, respectively, between the patch and the reference axis,
• wherein at least one of the first and second faces of the patch is positioned at a position axially between an axially inner end of the carcass ply and the inner surface of the pneumatic tire,
• wherein at least one of the first and second ends of the patch is positioned at a position radially between the bead toe and a radially outer end of the bead core of one of the beads, and
• wherein the radiating antenna is a half-wave dipole antenna.
