Problems solved by technology
 Such as figure 1 and figure 2 As shown, a kind of lens antenna of the present invention comprises metal horn 4 and lens 1 that feed source is housed, and this feed source is embedded in one end of metal horn 4 with smaller diameter, and lens 1 is embedded in metal horn 4 with larger diameter. one end. The lens 1 is made of artificial electromagnetic material. The lens 1 may only include the core plate 2 . The core board 2 is a planar dielectric board. Because the lens 1 is flat and has no curved surface, the lens 1 is easy to manufacture and process, and its manufacturing accuracy is also easy to control.
 Such as image 3 and Figure 4 As shown, the core board 2 contains several non-resonant basic units of the core board. The non-resonant basic unit of the core board can be located on the plane of the core board 2 away from the feed source, or on the plane of the core board 2 close to the feed source, or on two planes of the core board 2 at the same tim...
