FIELD: radio engineering.
SUBSTANCE: wide-angle scanning printed antenna array. The antenna array comprises: a printed circuit board, on which at least two patch antennas are located, each of which has at least one feed port, the patch antennas being rotated relative to each other around the normal in the centre of symmetry of the patch antenna in such a way that the corresponding the feed ports of the patch antennas, related to the same polarization, are rotated 180 degrees relative to each other, while the phases of the signals applied to the said feed ports, rotated relative to each other, differ by 180 degrees plus a phase shift for scanning control; dielectric protective shelter located above the printed circuit board; and passive elements for beamforming the array elements, located on the shelter above the patch antennas.
EFFECT: expanding the scanning range of the antenna array, increasing its efficiency and reducing losses.
