Abstract

Abstract Translated from German Die erfindungsgemässe Vorrichtung weist einen sich pyramidenförmig aufweitenden TEM-Wellenleiter (1) auf, welcher durch eine Wand (7) aus Hochfrequenz-Spitzenabsorbern (7.1) abgeschlossen ist und welcher einen asymmetrisch angeordneten, plattenförmigen Innenleiter (6) aufweist, welcher durch die Absorberwand (7) hindurch auf eine Anzahl von Abschlusswiderständen (8.1, 8.2, 8.3) geführt ist. Der TEM-Wellenleiter (1) weist weiter einen geschlossenen Aussenleiter (5) auf. Die Absorberwand (7) ist nach Art einer Kugelkalotte gekrümmt, wobei der Krümmungsmittelpunkt im Bereich der Spitze (2) des pyramidenförmigen TEM-Wellenleiter (1) liegt. The device according to the invention has a pyramid-widening TEM waveguide (1) which is closed off by a wall (7) made of high-frequency peak absorbers (7.1) and which has an asymmetrically arranged, plate-shaped inner conductor (6) which is passed through the absorber wall ( 7) is led through to a number of terminating resistors (8.1, 8.2, 8.3). The TEM waveguide (1) also has a closed outer conductor (5). The absorber wall (7) is curved in the manner of a spherical cap, the center of curvature being in the region of the tip (2) of the pyramidal TEM waveguide (1).
