Abstract :
The problem of synthesizing the structure of the diffractive antenna does not have a unique solution and the beampattern can be corrected by choosing the free parameters or/and optical scheme. All this can be applied to create directivity pattern of unconventional form, for example, conical beampattern. A numerical analysis of the antennas constructions and beampattern calculation is made.
