Lead-through antenna with a single- or double-ridge waveguide

摘要

The antenna has a radiating waveguide (20) adapted to pass through a wall (3) having an inner surface (31) and an outer surface (32). One end (21) of the radiating waveguide is in level with the outer surface of the wall. An excitation waveguide (10) is coupled to the radiating waveguide, where the excitation waveguide is arranged along the inner surface of the wall and arranged as a ridge waveguide. The excitation waveguide is arranged as a waveguide with double edges and filled with a dielectric material. An independent claim is also included for an antenna excitation system.
