<p>The antenna is intended for very short electromagnetic waves. Its reflector is in the form of a parabola sector. A feed horn has a single deflection, contains the feed point and extends up to the reflector. The antenna feed supply is of Cassegrain type, in which between the feed horn (5) and the main reflector (3) is provided a reversing system of two auxiliary reflectors (6, 7) for double beam reversing. The feed horn, the reversing system and the main reflector are in the form of a compact, enclosed module which has an output aperture (4). The auxiliary reflectors may be in the form of parabola sectors. The first auxiliary reflector (6) focus lies in the feed point (F2), while the focus of the second auxiliary reflector (7) coincides with that of the main reflector.</p> |
