Abstract

A tire and electronic device assembly includes an electronic device in which a transponder tag is coupled to a dipole antenna formed by first and second elongate antenna segments. The transponder tag and at least a portion of the dipole antenna are at least partially embedded within a compound having compatible permittivity and conductivity with operation of the dipole antenna and the electronic device is mounted to the tire apex in a position between the tire apex and the tire sidewall at a predetermined distance above an ending of the tire ply and in an orientation placing a longitudinal axis of the dipole antenna perpendicular to the cords of the tire ply.

Claims

1. A tire and electronic device assembly, the tire having a pair of beads, at least one ply layer having a plurality of parallel cords extending from one bead to an opposite bead, the ply layer further having a ply ending wrapped around the one bead, an outer sidewall, an apex component positioned above the one bead and extending upward to an apex component end, and a chafer component wrapped around the one bead and extending upward to a chafer component end, the assembly comprising:

an electronic device including a transponder tag, a dipole antenna formed by first and second elongate antenna segments electrically coupled at inward ends to the transponder tag and extending in opposite respective directions from the transponder tag;

a compound having compatible permittivity and conductivity with operation of the dipole antenna, the transponder device and at least a portion of the dipole antenna being at least partially embedded within the compound;

the transponder tag being operably mounted to the tire in a position between the tire apex and the tire sidewall at a predetermined distance above an ending of the tire ply in an orientation placing a longitudinal axis of the dipole antenna perpendicular to the cords of the tire ply.

2. The assembly of claim 1, wherein the transponder tag is positioned between the tire chafer ending and the tire apex ending.

3. The assembly of claim 1, wherein the transponder tag is located above an ending of the tire ply at a distance of at least 10 mm.

4. The assembly of claim 1, wherein the transponder tag is mounted to the tire apex.

5. The assembly of claim 1, wherein the compound substantially encapsulates the transponder tag and the inward ends of the antenna segments;

and each antenna segment includes a remote end segment extending compound-free.

6. The assembly of claim 1, wherein the transponder tag is positioned between the tire chafer ending and the tire apex ending in an axial tire direction at least a distance of 10 mm above the ending of the tire ply.

7. The assembly of claim 6, wherein the transponder tag is mounted to the tire apex.

8. The assembly of claim 7, wherein the antenna segments extend parallel with the tire apex ending.

9. The assembly of claim 8, wherein the antenna segments extend parallel with the ply ending.
