Abstract
Es wird eine Gruppenantenne mit einer Anzahl von Resonanz-Strahlerelementen (201k) und einem Speisenetzwerk (202), welches eine Anzahl von zwischen einen Eingangsanschluß (203) und die einzelnen Resonanz-Strahlerelemente (201k) parallel geschaltete Speiseleitungen (204k) enthält, beschrieben. Erfindungsgemäß ist es vorgesehen, daß die parallel geschalteten Speiseleitungen (204k) gleich lange Signalwege aufweisen und jeweils einen schwach angekoppelten Transmissionsresonator enthalten. Der Transmissionsresonator ist vorzugsweise durch zwei in den Speiseleitungen (204k) angeordnete Blindelemente (C1, C2), insbesondere durch Kapazitäten gebildet. It becomes a group antenna with a number of resonance radiator elements (201 k ) and a feed network (202) which contains a number of feed lines (204 k ) connected in parallel between an input connection (203) and the individual resonance radiator elements (201 k ) , described. According to the invention, it is provided that the feed lines (204 k ) connected in parallel have signal paths of equal length and each contain a weakly coupled transmission resonator. The transmission resonator is preferably formed by two dummy elements (C 1 , C 2 ) arranged in the feed lines (204 k ), in particular by capacitors.
