FIELD: antenna equipment; may be used for creation of active phased arrays with dense packing of element ((d≅ 0,5λ)) and wide-angle scanning ((±90°)). SUBSTANCE: waveguide slit resonance cruciform radiator is made on waveguide 1 with U-shaped profile of cross-section, two wide walls of square shape and diagonal size of 0.5, parallel to internal partition 4. Front wide wall 2 of waveguide has cruciform resonance slit 3. Short-circuiting metal plugs 7, 8 are installed in butt planes of U-shaped waveguide. Two quarter-wavelength slits 5 are cut in internal partition of U-shaped waveguide along plugs. EFFECT: higher efficiency. 1 dwg
