FIELD: radio engineering, communication.SUBSTANCE: invention relates to antenna engineering. The mirror-horn antenna has a planar reflector in form of top, bottom and middle metal plates mounted parallel to each other, and a parabolic cylinder made of metal and mounted between the bottom and top plates and has ohmic contact with said plates, and its axis is perpendicular to the planes of said plates; the middle plate has an edge situated between the parabolic cylinder and its focus, wherein the gap between the edge and the parabolic cylinder has a constant width; a feed element mounted between the top and middle plates and made in form of at least one exciter and a wall made of metal and situated between the bottom and middle plates, perpendicular to said plates; the wall is also perpendicular to the plane of symmetry of the guide of the parabolic cylinder; the top and middle plates have straight edges which are perpendicular to the plane of symmetry of the guide of the parabolic cylinder and lie at a distance from the peak of the guide of the parabolic cylinder which is greater than the focal distance thereof; a radiator in form of two rectangular metal plates whose edges are joined to the straight edges of the top and middle plates, wherein the planes of the rectangular plates have an intersection line lying between the top and middle plates.EFFECT: high efficiency and resolution of the mirror-horn antenna.10 cl, 20 dwg |
