vehicle tyres with stahlgu00fcrteldru00e4hten and with in the area of the tread and dipole antenna

摘要

A vehicle tire having steel belt cords is provided with a dipole antenna arranged in the area of the tire tread for data transmission, in particular for a transponder for transmitting energy and measured quantities. The dipole antenna cooperates with a sending and receiving antenna arranged on the vehicle. The dipole antenna is arranged essentially across the steel belt cords. If the belt angles of the two intersecting plies of steel belt cords with respect to the longitudinal axis of the tire profile are not the same, then the dipole antenna with its longitudinal axis is aligned essentially perpendicular to the axis of symmetry between the two intersecting plies of steel belt cords. The dipole antenna preferably has an effective dipole length of 6 cm when using a transmission frequency of 2.45 GHz. The vehicle's sending and receiving antenna is preferably aligned so that is has essentially the same polarization plane as the dipole antenna.
