Abstract

Als Mehrband-Rundstrahlantenne mit versenktem Einbau in eine metallische Oberfläche (1) sind mehrere konzentrische Ring­ schlitzantennen evtl. mit einem zentralen Unipol (13) vorge­ sehen. Die einen grabenförmigen Ringschlitz (7,12) aufweisenden Ringschlitzantennen werden jeweils über eine Koaxialleitung (2,8), eine zurückgesetzte Verzweigungsstelle (4,9) und mehrere gleichmäßig an den jeweiligen Ringschlitz angeschlossene Koaxialleitungsstücke (5,6; 10,11) versorgt, die so korbförmig geführt sind, daß sich im Mittelbereich (Korbinnenraum) Raum jeweils für die Ringschlitzantennen der höheren Frequenzbänder ergibt. Die Ringschlitzantenne nach der Erfindung ist zur Verwendung als rundstrahlende, mehrbandige Flugzeug-Transponder-­ Antenne geeignet, die mit der Flugzeugaußenhaut bündig abschließt. As a multi-band omnidirectional antenna with recessed installation in one metallic surface (1) are several concentric ring slot antennas may have a central unipole (13) see. Which have a trench-shaped ring slot (7, 12) Ring slot antennas are each via a coaxial line (2,8), a reset branch point (4,9) and several evenly connected to the respective ring slot Coaxial line pieces (5,6; 10,11) supplied, which are basket-shaped are led that there is space in the central area (basket interior) each for the ring slot antennas of the higher frequency bands results. The ring slot antenna according to the invention is for Use as omnidirectional, multi-band aircraft transponder Suitable antenna, which is flush with the aircraft outer skin completes.
