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