Large power ultra-wide-beam shaping antenna

The utility model discloses a high power superwide beam shaped antenna, consisting of a shaped convex reflecting curved surface, a feed source, a wave guide feeder line and a supporting bracket. The high power superwide beam shaped antenna is characterized in that the reflecting surface is the shaped convex reflecting curved surface, the feed source is an offset focus feed source and is positioned in the front of the shaped convex reflecting curved surface as well as is parallel and level with the bottom of the reflecting curved surface, and the surface of the feed source opening aligns to the scattering center of the convex reflecting curved surface and has 20 working wavelengths from the scattering center of the convex reflecting curved surface; and the size of the shaped convex reflecting curved surface is determined by energy loss of the radiation from the feed source to the reflecting curved surface not more than 10 percent, and the front projecting area is 356 Lambda square meters; and the shaped convex
