Abstract

Der Erfindung liegt die Aufgabe zugrunde, eine derartige Fahrzeugantenne in der Weise weiterzubilden, daß sie eine möglichst gleichmäßige Rundum-Richtcharakteristik im Sende- und Empfangsbetrieb aufweist. The invention has for its object such Train vehicle antenna in such a way that it is a as uniform as possible all-round directional characteristic in the transmission and has receiving operation.

Die Lösung der Aufgabe besteht darin, daß an oder in der Fahrzeugkarosserie (11) zwei oder mehrere Schlitzantennen (12, 13, 14) verteilt angeordnet sind. Jede Schlitzantenne ist über ein n . λ/2 langes Antennenkabel (25, 26, 27) mit einem zentralen Einspeisepunkt (28) verbunden. n ist eine ganze Zahl und λ die mittlere Betriebswellenlänge. The solution to the problem is that on or in the Vehicle body (11) two or more slot antennas (12, 13, 14) are arranged distributed. Every slot antenna is about an n. λ / 2 long antenna cable (25, 26, 27) with connected to a central entry point (28). n is one integer and λ the mean operating wavelength.

In der Zeichnung ist eine perspektivische Ansicht eines Kraftfahrzeuges mit drei Schlitzantennen gezeigt. In the drawing is a perspective view of a Motor vehicle shown with three slot antennas.
