ABSTRACT:
An antenna for transmitting and/or receiving in the heating field of a window pane on a motor vehicle. The heating field has an HF-connection designed to couple or decouple high-frequency signals, and heating connections for feeding the heating power. An AC generator generates the heating wattage in the form of AC current, through a transformer. The heating power is supplied to the primary winding of the transformer and picked up on the secondary winding of the transformer and supplied to the heating field via heating connections. The primary winding and the secondary winding of the transformer are insulated to reduce the transmission of high frequency currents so that the heating field antenna does not have low resistance even at the lowest frequencies.
