Mounting transponders and antennas in pneumatic tires
First Claim
1. A pneumatic tire in combination with an antenna and an antenna coupling coil for a removable transponder module having a transponder coupling coil for mounting to an inner surface of the pneumatic tire, characterized in that:
- the antenna is functionally connected to the removable transponder module by mating features which position the transponder coupling coil in close proximity and concentric to the antenna coupling coil;
the antenna comprises an elongate first antenna segment having a first end and a second end and an elongate second antenna segment having a third end and a fourth end;
the first antenna segment is electrically connected to a first wire end of the antenna coupling coil and extends circumferentially in a first direction from the antenna coupling coil at least partially around the inner surface of the tire; and
the second antenna segment is electrically connected to a second wire end of the antenna coupling coil and extends circumferentially in a second direction, opposite from the first direction, from the antenna coupling coil at least partially around the inner surface of the tire.

Abstract
An antenna comprises two elongate antenna segments (740, 740′, 862, 940, 970, 1208/1212, 1300, 1320, 1322/1324, 1360, 1360′, 1520, 1520′, 1520″, 1523, 1523′, 1620, 1720, 1820, 1920) which extend from first ends (742, 742′, 864, 942, 972, 1322e, 1362, 1362′, 1522, 1522′, 1522″, 1622, 1922)/(744, 744′, 868, 944, 974, 1324e, 1364, 1364′, 1524, 1524′, 1524″, 1624, 1924) connected to the antenna coupling coil in opposite directions to second ends (744, 744′, 868, 944, 974, 1322c, 1366, 1366′, 1524, 1524′, 1524″, 1624, 1924)/(742, 742′, 864, 942, 972, 1324c, 1368, 1368′, 1522, 1522′, 1522″, 1622, 1922) at least partially around the inner surface of the tire. The antenna and antenna coupling coil are mounted to the inner surface of the tire, and the transponder module is attached to the antenna coupling coil in a way which positions the transponder coupling coil in close proximity and concentric to the antenna coupling coil, thereby providing effective transformer-type coupling between the transponder and the antenna.
