Abstract
Es ist eine Vorrichtung zur Befestigung eines Erregerelements (2) in einem metallischen Hohlleiter (3) einer Antenne (1) und zum elektrischen Anschluß desselben an eine außerhalb des Hohlleiters (3) angeordnete Koaxialleitung (4) vorgesehen, die kostengünstig ist und bei der geringe Verlustleistungen auftreten. Die Vorrichtung umfaßt einen eine Öffnung des Hohlleiters (3) verschließenden Grundkörper (6) mit einer Bohrung (6.1) und einen metallischen Hohlzylinder (9), durch den ein Innenleiter der Koaxialleitung (9) hindurchgeführt ist, der einen in die erste Bohrung (6.1) eingesteckten ersten Abschnitt (9.1) aufweist und der einen zweiten Abschnitt (9.2) aufweist, über den ein Endbereich (10) eines Außenleiters der Koaxialleitung (4) gestülpt ist. Ein erstes Ende (2.1) des Erregerelements (2) ist auf einem Ende (12) des Innenleiters befestigt. A device for fastening an excitation element (2) in a metallic waveguide (3) of an antenna (1) and for electrically connecting the same to a coaxial line (4) arranged outside the waveguide (3) is provided, which is inexpensive and low Power losses occur. The device comprises a base body (6) closing an opening of the waveguide (3) with a bore (6.1) and a metallic hollow cylinder (9) through which an inner conductor of the coaxial line (9) is guided, which leads into the first bore (6.1 ) inserted first section (9.1) and which has a second section (9.2) over which an end region (10) of an outer conductor of the coaxial line (4) is slipped. A first end (2.1) of the excitation element (2) is attached to one end (12) of the inner conductor.
