ABSTRACT:
A pneumatic tire has an integrated circuit transponder which, upon interrogation by an external RF signal, transmits tire identification and/or other data in digitally-coded form. The transponder has a coil antenna of small enclosed area as compared to the area enclosed by an annular tensile member comprising a bead of the tire. The annular tensile member, during transponder interrogation, acts as the primary winding of a transformer. The coil antenna is loosely coupled to the primary winding and is the secondary winding of the transformer. The coil antenna is substantially planar in shape, and, when positioned between the innerliner of the tire and its carcass ply, the transponder may include a pressure sensor responsive to tire inflation pressure.
