ABSTRACT:
A thin film antenna for a vehicle antenna is described. The principal element of the antenna is formed of a thin transparent film of conducting material having a horizontally elongate generally rectangular shape. The principal element is supported on or within the upper region of a vehicle window and is electrically fed with respect to a ground point on the vehicle body to effect coupling with the metallic structure of the vehicle and enhance antenna performance. An optional auxiliary element can be attached to the principal element to provide a means for tuning the impedance of the antenna.
