Abstract (en)
[origin: WO2005043672A1] The invention relates to a vehicle window antenna that is equipped with conductor assemblies for both FM (LFM) and AM (LAM) reception, said assemblies being separated with regard to HF voltage from the heating circuit (B) by means of decoupling and matching circuits (EA1, EA2). The second decoupling and matching circuit (EA2) in the AM circuit is located downstream of the first decoupling and matching circuit (EA1) in the FM circuit and is situated in particular in the auxiliary circuit of said first decoupling and matching circuit. The FM structures can thus be used as supply conductors for the AM structure. The filtering requirements for the second decoupling and matching circuit can be kept to a minimum.
