Claims (4)

1. A broadband antenna array containing a flat dielectric base with metallized layers in which the excitation system and the radiating aperture associated with it are formed, characterized in that the radiating aperture is formed of k-horn emitters, where

located at m levels, where m = 0, 1, 2 ..., and each emitter of level m ≠ 0 is formed by two intersecting horns, the intersection point of adjacent walls of which lies on the symmetry axis of the horn emitter of the level (m + 1) at a distance of more than half wavelengths to each outer wall in a direction perpendicular to the axis of symmetry.  2. The broadband antenna array according to claim 1, characterized in that each horn emitter of the next level is formed by a pair of horn emitters of the previous level, the adjacent walls of which intersect at a point lying on the axis of symmetry of the horn emitter of the next level at a distance of more than half the wavelength to their outer walls, and has an aperture of not less than two times the aperture of the horn emitter of the previous level.  3. Broadband antenna array according to claims 1 and 2, characterized in that the horn emitters of level m = 0 are connected to the excitation system and their number is even. 4. The broadband antenna array according to claims 1 and 2, characterized in that the number of horn emitters at the m level (where m = 0, 1, 2, ...) is determined by the ratio 2 ^{p - m} , where p is the number of level transitions.
