Abstract
(DE)
Die Erfindung betrifft eine Wellenleiteranordnung (1), umfassend einen ersten Wellenleiter (2), einen zweiten, als dielektrischer Multi-Mode-Wellenleiter ausgebildeten Wellenleiter (3), sowie einen Wellenleiterübergang (4) zur Übertragung einer elektromagnetischen Welle (5) zwischen dem ersten Wellenleiter (2) und dem zweiten Wellenleiter (3), aufweisend ein dielektrisches Wellenleiterstück (6), das zwischen dem ersten Wellenleiter (2) und dem zweiten Wellenleiter (3) angeordnet ist. Das dielektrische Wellenleiterstück (6) ist ausgebildet, um zumindest in einem dem ersten Wellenleiter (2) zugewandten, vorderen Abschnitt (7) eine geringere Modenzahl zu führen, als der zweite Wellenleiter (3) zu führen vermag.
(EN)
The invention relates to a waveguide assembly (1) comprising a first waveguide (2), a second waveguide (3) designed as a dielectric multimode waveguide, and a waveguide transition (4) for transmitting an electromagnetic wave (5) between the first waveguide (2) and the second waveguide (3), having a dielectric waveguide piece (6) which is arranged between the first waveguide (2) and the second waveguide (3). The dielectric waveguide piece (6) is designed so as to be capable of guiding a smaller mode number than the second waveguide (3) at least in a front section (7) facing the first waveguide (2).
(FR)
L’invention concerne un ensemble de guides d’ondes (1), comprenant un premier guide d’ondes (2), un deuxième guide d’ondes (3) conçu comme un guide d’ondes multimode diélectrique, ainsi qu’une jonction de guides d’ondes (4) destinée à la transmission d’une onde électromagnétique (5) entre le premier guide d’onde (2) et le deuxième guide d’onde (3), et présentant une pièce diélectrique pour guides d’ondes (6) qui est disposée entre le premier guide d’onde (2) et le deuxième guide d’onde (3). La pièce diélectrique pour guides d’ondes (6) est conçue pour être en mesure de gérer, au moins dans une section avant (7) tournée vers le premier guide d’ondes (2), un nombre de modes inférieur à celui du deuxième guide d’ondes (3).
