Abstract

Ein einfach herstellbarer und sehr breitbandiger Richtkoppler mit einem Koppelraum (KR), an dessen Stirnseiten je zwei Hohlleiter (H1, H2, H3, H4) angekoppelt sind, weist zwischen den einzelnen Hohlleitern (H1, H2, H3, H4) und dem Koppelraum (KR), in dem neben dem Grundwellentyp (H10) die höheren Wellentypen (H11 und E11) ausbreitungsfähig sind, Koppelblenden (KB1, KB2, KB3, KB4) auf. Außerdem entspricht die Höhe des Koppelraums (KR) mindestens dem 2,5-Fachen der Höhe (b) einer Koppelblende (KB1, KB2, KB3, KB4).

Figure 00000001
An easy-to-manufacture and very broadband directional coupler with a coupling space (KR), to the front of which two waveguides (H1, H2, H3, H4) are coupled, points between the individual waveguides (H1, H2, H3, H4) and the coupling space ( KR), in which, in addition to the basic wave type (H10), the higher wave types (H11 and E11) can be spread, coupling plates (KB1, KB2, KB3, KB4). In addition, the height of the coupling space (KR) corresponds to at least 2.5 times the height (b) of a coupling aperture (KB1, KB2, KB3, KB4).
