FIELD: radio engineering; microwave feedthrough antenna arrays using electrical beam scanning; various radars. ^ SUBSTANCE: proposed feedthrough antenna system has coaxially mounted reflector, horn-type microwave feed, and feedthrough phased antenna array. Device of first design alternate has its horn-type microwave feed disposed between feedthrough phased antenna array and reflector made in the form of parabolic mirror with polarizer, diameter of parabolic mirror being equal to (1.0 - 1`.2) of maximal linear dimensions of feedthrough phased antenna array, as viewed on top. Device of second design alternate has its reflector made in the form of flat mirror with polarizer free to turn about spherical hinge disposed at supporting point in symmetry center of flat mirror and on common axis of antenna system; its horn-type microwave feed is disposed between feedthrough phased antenna array and flat mirror and is mounted beyond this array aperture so that its longitudinal axis crosses flat mirror supporting point, feedthrough phased antenna array and flat mirror being equally shaped, as viewed on top, and linear dimensions of flat mirror being equal to (0.7 - 0.8) of respective linear dimensions of mentioned feedthrough array. ^ EFFECT: enlarged functional capabilities due to enlarged angular beam scanning sector. ^ 13 cl, 6 dwg |
