US Patent 6885291 Mouting transponders and antennas in pneumatic tires

Method and apparatus for mounting a transponder module (400, 702, 951, 1000, 1020, 1751, 1752, 1852, 1852′, 1951, 1951a) and a separate antenna (1520, 1520′, 1520″, 1620, 1720, 1820, 1920) to an inner surface (1504, 1504′, 1504″, 1704, 1804) of a pneumatic tire (312, 650, 1204, 1350, 1350′, 1550, 1550′, 1550″), and for coupling the transponder module to the antenna by coupling coils which are included with the transponder module (450, 760, 953, 1004, 1024) and the antenna (750, 750′, 866, 938, 968, 1538, 1538′, 1538″, 1638, 1638′, 1738, 1738′, 1838, 1838′, 1938). The transponder module mounting methods generally allow it to be inserted, removed, or accessed for maintenance at any time during the tire's life cycle, and allow sensing access to the tire's inner atmosphere.
