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, 1322 e , 1362, 1362', 1522, 1522', 1522'', 1622, 1922 )/( 744, 744', 868, 944, 974, 1324 e, 1364, 1364', 1524, 1524', 1524'', 1624, 1924 ) connected to the antenna coupling coil in opposite directions to second ends ( 744, 744', 868, 944, 974, 1322 c, 1366, 1366', 1524, 1524', 1524'', 1624, 1924 )/( 742, 742', 864, 942, 972, 1324 c, 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.
