In article the limiting scan angle of the planar phased antenna lattice (phased-array) is certain. Antenna elements of broadband phased-array which should possess steady directional diagram, are considered by practically constant polarization of a formed electro-magnetic field, and also to have minimal mass-dimension parameters. As such elements are chosen низкопрофильные planar radia-tors in the form of the overturned conic aerial. The considered type of the antenna elements making its cloth, allows to carry out steady wide-angle azimuthal scanning (±45º), the generated narrow directional diagram in a range of operating frequencies with overlap 2.6:1. Профильность the lattice is not exceeded with 50 mm., that allows to use it at the boosted wind loads and as it is essential to lower perceptibility and mass-dimension parameters of the radioelectronic complexes of various designation, at use similar phased-array in their structure. Article contains 11 figures and 5 bibliographic sources of the information.
