Abstract

Modenkoppler für Monopulsanwendungen in einem Antennenspeisesystem, zum Gewinnen von Winkelablagen in Azimut und Elevation, mit einem Haupthohlleiter (HH), in welchem mehrere Moden ausbreitungsfähig sind, und an den modenselektive Ein/Auskoppeltore angesetzt sind. Die Ein/Auskoppeltore sind sämtlich einfache, an den Haupthohlleiter angesetzte Norm-Hohlleiter, in denen nur der H₁₀-Grundwellentyp ausbreitungsfähig ist. Der (H₁₁+E₁₁)-Mode wird durch ein Trennblech (B) im Haupthohlleiter in zwei gegenphasigen Hohlleiterwellen überführt und über einen Koppelbügel (K) in einen seitlich auf gesetzten zweiten Hohlleiter (H₂) eingekoppelt. Die Vorderkante des Trennblocks ist als Reflektor für den H₀₁-Mode ausgebildet, so daß dieser Mode in zwei symmetrisch an den Haupthohlleiter angesetzte erste Hohlleiter (H₁₁, H₁₂) und über eine H-Ebenen-Verzweigung (HV) in einen gemeinsamen Abgangshohlleiter (H₁) ausgekoppelt wird. Mode coupler for monopulse applications in an antenna feed system, for obtaining angular shelves in azimuth and Elevation, with a main waveguide (HH), in which several Modes are spreadable, and at the mode selective In / decoupling gates are attached. The coupling / decoupling gates are all simple, attached to the main waveguide Standard waveguide in which only the H₁₀ basic wave type is spreadable. The (H₁₁ + E₁₁) mode is by a Divider (B) in the main waveguide in two antiphase waveguide shafts transferred and via a coupling bracket (K) into one laterally coupled onto the second waveguide (H₂). The Front edge of the separator block is used as a reflector for the H₀₁ fashion trained so that this fashion in two First waveguide applied symmetrically to the main waveguide (H₁₁, H₁₂) and an H-level branching (HV) in one common output waveguide (H₁) is coupled out.
