METHOD OF DETERMINING THE SURFACE OF A DIELECTRIC BIFOCAL LENS ANTENNA Russian patent published in 2020 - IPC H01Q15/08 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the field of antenna equipment and can be used for designing, simulating and manufacturing of bifocal lenticular antennae. For each of the beams subjected to refraction on the surface of the lens, an analytical expression is recorded, which determines its electric length and depends on coordinates of the points of the illuminated and shadow surfaces of the lens. Then, successively using numerical methods, determining three points lying on shadow and illuminated surfaces, making, based on obtained coordinates of points, two systems of equations, solution of which are coefficients of power polynomials approximating the illuminated and shadow surfaces of the lens collimator.

EFFECT: technical result consists in the possibility of unambiguous determination of the surface of the lens antenna.
