Abstract

Die Erfindung betrifft ein Antennensystem für den Empfang digitaler terrestrischer Signale, insbesondere von DVB-T-Signalen, wobei zur Erzielung eines konstanten Gewinns bei guter Anpassung erfindungsgemäß vorgesehen ist, daß zumindest zwei auf λ/4 abgestimmte Antennen (2, 3) über ein Anpassungsnetzwerk (7) zusammengeschaltet sind.

Figure 00000001
The invention relates to an antenna system for receiving digital terrestrial signals, in particular DVB-T signals. In order to achieve a constant gain with good adaptation, the invention provides that at least two antennas (2, 3) matched to λ / 4 are provided via an adaptation network (7) are interconnected.
