Abstract. The designs of dielectric lens antennas are presented, and their applications are defined. A numerical research of the energy, mass-sized and aerodynamic parameters of dielectric lens antennas was carried out. The possibility of solving the problem of ultra-wide-angle electric scanning by applying dielectric lenses of various shapes is shown. The value of the increasing of the scanning sector of the radiating antenna array with a dome lens is estimated. The possibility of changing the scanning diagram, as well as increasing the gain when scanning in a wide sector of angles by manufacturing a lens from ferrite, is estimated. The dependences of the mass of lens with changing its geometric dimensions are obtained, and the possibility of reducing the mass of the lens at their rational selection is shown. The dependences of the aerodynamic drag coefficient of the antenna on the geometric sizes of the lens are obtained and the possibility of its reduction is shown.

Keywords: dielectric lens antenna, antenna array, antenna gain, aerodynamic drag coefficient, scanning sector, scanning diagram.
