Abstract
A device is provided for fastening an excitation element (2) in a metal waveguide (3) of an antenna (1) and for electrically connecting the same to a coaxial line (4) arranged outside the waveguide (3), and which is cost effective and in which low power losses occur. The device comprises a basic member (6), which seals an opening in the waveguide (3), has a bore (6.1), and a metal hollow cylinder (9), through which an inner conductor of the coaxial line (9) is guided, which hollow cylinder has a first section (9.1) plugged into the first bore (6.1), and which has a second section (9.2), over which an end region (10) of an outer conductor of the coaxial line (4) is pushed. A first end (2.1) of the excitation element (2) is fastened on one end (12) of the inner conductor.
