Abstract
A valve for a tire pressure monitoring system in which the valve acts a coaxial conductor to transmit a signal to a receiver presented. A valve stem electrically isolated from a valve pin form the coaxial conductor. In a tire pressure monitoring system, a tire pressure measurement module is positioned inside a tire. In one embodiment, a conductive radiating structure is electrically connected or coupled to the valve pin to receive the tire pressure information signal and transmit it to a receiver. The above configuration further permits a rechargeable battery in the tire pressure measurement module to be recharged via the tire valve. The valve pin and valve stem, being electrically isolated from one another, are used as recharging paths for the battery.
