FIELD: antenna engineering. SUBSTANCE: antenna that can be used in wide-angle scan communication and radar facilities has its lens which is made of ferrite, bulged toward edges, and installed above flat circular antenna array. Lens base is secured in annular slot of cylindrical magnetic circuit having same central axis as lens. Outer diameter of magnetic circuit is greater than diameter of antenna lens. Electromagnet ring windings are disposed on annular slot walls and on outer surfaces of cylindrical magnetic circuit. Magnetic-circuit rods are fitted between array antennas. EFFECT: enhanced gain within wide sector of angles. 1 cl, 4 dwg
