Abstract
A pneumatic tire and monitoring device for monitoring an engineering condition of a pneumatic tire includes a pneumatic tire having a sidewall and a plurality of reinforcing cords carried in the sidewall. The monitoring device includes a sensing element that senses at least an engineering condition of a pneumatic tire and transmits the gathered data from the monitoring device to a data gathering device outside of the tire. The transmission occurs through a dipole antenna that is in communication with the sensing element. The dipole antenna is disposed substantially perpendicular to the reinforcing cords in order to maximize the probability of signal propagation through the tire sidewall.
