Microwave antenna e.g. for keyless entry systems, park and assistant systems, has dielectric carrier with strip circuit and metallic or metalized cover arranged over dielectric carrier on its strip leader side into a horn

摘要

The antenna has a dielectric carrier (1) with a strip circuit. A metallic or metalized cover (3) is arranged over the dielectric carrier on its strip leader side into a horn and waveguide emitters are integrated. The exciter end funnel is also arranged in it and a transformer is arranged over the strip circuit. The transformer element has a dielectric body, where the distance of the lower surface (6) of the body to the strip circuit decreases toward the opening of the waveguide emitter (4).
