Radiating aperture waveguide feed antenna |
摘要 |
The invention proposes a primary feed providing an asymmetrical illumination compatible with an elliptical reflector and having a small space requirement. The invention uses a short rod to modify the radiation of an open waveguide section. The invention is an antenna comprising a radiating feed made up of a waveguide 1, one end of the waveguide forming a radiating aperture. The end forming the radiating aperture is fitted with a rod made of dielectric material, said rod being partly inserted 2, 3 in the waveguide 1. The rod is extended outside the waveguide over a length L less than twice the guided wavelength and the section of the rod develops outside the waveguide differently in each of the planes. <IMAGE> |
