摘要： A glass window antenna for use in a motor vehicle provides satisfactory antenna characteristics while making best use of the space of a glass window with a heating conductor as the main antenna element which is heated by a pair of power supply lines through choke coils. In a preferred embodiment, a capacitor is connected across the power supply lines at a position between the choke coils and the heating conductor to minimize the loss or leakage of radio signals from the heating conductor through the choke coils. A symmetrical pair of wires coupled with each other is formed on the glass window and connected to ends of the heating conductor to improve a radio wave reception gain.
