Micro-wave antenna with ultra-high performance and feed component thereof

The utility model discloses a micro-wave antenna with ultra-high performance and the feed component thereof. The feed component is in a rotationally symmetrical structure, and comprises a sub-reflection surface, a medium head, a waveguide, and a bottom seat. One end of the waveguide is interposed into the bottom seat, while the other end is provided for interposing the medium head. The second end of the medium head is arranged to cover the sub-reflection surface according to the shape of the end surface of the end. The portion of the medium head interposed into the waveguide comprises at least one cylinder portion. A plurality of cylindrical surface with different diameters are provided on the lateral side portion exposed out of the waveguide. An oblique cone surface disposed at the center and recessed facing the first end is provided on the end surface of the second end, and a circular ring plane is formed on the periphery of the oblique cone surface. At least one stage of the micro-interference structure is arranged onto the oblique cone shaped surface. The micro-wave antenna with ultra-high performance and the feed component of the utility model has great electric performance, simple and compact physical structure, and relatively low production cost.
