Abstract
A vehicle window/antenna system with enhanced heating and AM/FM reception. The system includes a window and a heating/antenna grid supported thereon. The grid is separated into upper and lower portions, and functions as an FM antenna. A flat AM antenna is supported on the window between the upper and lower grid portions. The positioning of the AM antenna within the heating grid enables ice and snow to be cleared from the AM antenna. Antenna leads extend from both the upper and lower grid portions as well as the AM antenna. The two FM leads are connected to a Balun transformer to balance the FM signals.
