Abstract
Electromagnetic field transmissions between a sensor unit mounted on the inside surface of a tire and a sensor control unit mounted on the vehicle body are attenuated by the wall surface of a tire disposed between the units, and sensitivity is reduced. A booster antenna (18) is embedded in the tire wall surface between the sensor unit (6) and the sensor control unit (10). The booster antenna (18) is a coil antenna, and is configured so that the resonance frequency, which corresponds to the impedance and capacitance component of the booster antenna coil, corresponds to the frequency f0 of the transmission electromagnetic field of the sensor control unit (10). The booster antenna (18) is disposed in a position in which a magnetic coupling is formed with the coil antenna of the sensor unit (6), and transmissions via the electromagnetic field between the sensor unit (6) and the sensor control unit (10) are carried out through the booster antenna (18).
