<p>An annular apparatus (301) is embedded within the toroidal region of a pneumatic tire (101), or in a ring of elastomeric material (201) attached to a tire rim. The apparatus is coaxially positioned with respect to the tire or wheel and preferably is embedded in the tire at its equatorial plane (EP), and includes a radio-frequency transponder, including an integrated circuit chip (121); and optional sensors in the chip or associated with the chip; the integrated circuit chip of the transponder has at least the capacity to transmit data relating to tire or wheel identification. The antenna comprises a composite of an electrical conductor (141) and a rubber matrix (201) wherein the composite is capable of substantial elongation.</p> |
