Device for fastening an excitation element in a metal waveguide of an antenna and for electrically connecting the same to a coaxial line arranged outside the waveguide
First Claim
1. A device for fastening an excitation element (2) in a metal waveguide (3) of an antenna (1) and for electrically connecting the excitation element (2) to a coaxial line (4) arranged outside the waveguide (3), which device comprises:
- a metal basic member (6) which seals an opening in the waveguide (3) and has a first through-bore (6.1),a metal hollow cylinder (9), through which an inner conductor, surrounded by an insulation, of the coaxial line (4) 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, anda metal sleeve (11) which is fastened by crimping and which coaxially embraces the second section (9.2) of the hollow cylinder (9) and the end region (10) of the outer conductor, a first end (2.1) of the excitation element (2) being fastened on an insulation-free end (12) of the inner conductor which extends into the interior of the waveguide (3).

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.
