Abstract

Das dual polarisierte Antennenelement besteht aus einem in einer ersten Ebene liegenden planaren Strahlerelement (2), einer in einer zweiten Ebene angeordneten metallisierten Fläche, die mindestens zwei unterhalb des Strahlerelements (2) verlaufende Schlitze (5, 6) aufweist, und einer in einer dritten Ebene angeordneten, mit den Schlitzen (5, 6) gekoppelten Speiseleitungsstruktur (7, 8). Einer (5) der beiden Schlitze verläuft auf einer Symmetrielinie (11) des Strahlerelements (2), und ein weiterer Schlitz (6) verläuft orthogonal und spiegelsymmetrisch zu der Symmetrielinie (11). Damit es zu einer möglichst hohen Entkopplung der beiden Polarisationen kommt, ist der orthogonal zur Symmetrielinie (11) verlaufende Schlitz (6) an zwei spiegelsymmetrisch zur Symmetrielinie (11) liegenden Punkten (12, 13) mit einer Speiseleitung (8) gekoppelt, die als spiegelsymmetrisch verlaufende Leitungsverzweigung ausgebildet ist.
