Abstract (en)
[origin: WO2006018079A1] The invention relates to a receiving antenna system (1) with a higher bandwidth. Said system consists of several active vertical antennae (2<SUB>1</SUB>, 2<SUB>2</SUB>, , 2<SUB>N</SUB>), which have an electrically active antenna height that is adapted to the respective receiving frequency range. The invention is characterised in that the mutual electromagnetic coupling between the individual antennae (2<SUB>1</SUB>, 2<SUB>2</SUB>, , 2<SUB>N</SUB>), which are positioned at a short distance from one another, is minimised.
