FIELD: antenna devices. SUBSTANCE: device is designed as open end of round waveguide with flange and dielectric lens which is shaped as rotation body. Cone-shaped recess is made in dielectric lens along its axis. Cone base is matched to funnel plane, its diameter dc conforms to condition 0,7λ ≅ dc≅ 2λ, where λ is operation wavelength, and cone vertex angle vc conforms to condition 69° ≅ Φc ≅ 110°. EFFECT: increased functional capabilities. 4 cl, 2 dwg
