Vehicle window antenna.

摘要

It comprises a principal element (20) of an antenna (18) which is formed of a thin transparent film of conductive material having a horizontally elongate and generally rectangular shape. The principal element (20) is supported on or within the upper region (14c) of the vehicle window and is electrically fed with respect to a ground point (32) on the vehicle body to effect coupling with the metallic structure of the vehicle and enhance antenna performance. An optional auxiliary element (36) can be attached to the principal element (20) to provide a means for tuning the impedance of the antenna (18). <IMAGE>
