Abstract

Die Erfindung betrifft ein Schlitzstrahlerelement in Form eines rechteckigen Hohlleiters (1) umfassend

  • mindestens einen in der Mitte der einen Breitseite (4) befindlichen Schlitz (2),
  • einen in der Mitte der Innenoberfläche der anderen Breitseite (9) angeordneten rechteckigen Steg (3), wobei der Schlitz (2) und der Steg (3) sich jeweils entlang der Längsrichtung des Hohlleiters (1) erstrecken,
  • im Bereich des Schlitzes (2) angeordnete Kopplungsmittel (5), insbesondere einen Stift, welche den Schlitz (2) zur Abstrahlung elektromagnetischer Energie anregen,
  • auf der dem Schlitz (2) zugewandten Oberfläche des Stegs (3) ausgeführten Kompensationsmittel (6), welche die durch die Kopplungsmittel (5) verursachte Fehlanpassung des Hohlleiters (1) an den, den Hohlleiter (1) mit elektromagnetischer Energie speisenden Generator kompensieren, wobei die Kompensationsmittel (6) derart ausgeführt sind, dass der Steg (3) im Bereich des Schlitzes (2) eine stufenförmige Vertiefung aufweist.
Figure 00000001
The invention relates to a slot radiator element in the form of a rectangular waveguide (1)
  • at least one slot (2) located in the middle of one broad side (4),
  • a rectangular web (3) arranged in the center of the inner surface of the other broad side (9), wherein the slot (2) and the web (3) each extend along the longitudinal direction of the waveguide (1),
  • coupling means (5) arranged in the region of the slot (2), in particular a pin, which excite the slot (2) for the emission of electromagnetic energy,
  • on the surface of the web (3) facing the slot (2) compensating means (6) which compensate for the mismatch of the waveguide (1) caused by the coupling means (5) with the generator supplying electromagnetic energy to the waveguide (1); wherein the compensation means (6) are designed such that the web (3) in the region of the slot (2) has a stepped depression.
