<p>Multibeam antenna capable of receiving/transmitting signals at the same frequency, in one or more directions, simultaneously, essentially consisting of one or more radiating elements (2), of a parabolic reflector (1) with square-shaped edge (3), being one of the four vertices (4) of the square which circumscribes the reflector (1) located close to the focal axis of the paraboloid. The radiating elements (2) and, correspondingly, the operating directions, are aligned along one of two possible orthogonal planes. The invention provides, with respect to previous solutions: maximum isolation between operating directions, at the same antenna gain; minimum size of the reflecting surface, since the rectangular shape reduces the overall dimensions and makes packaging - and therefore transportation - easier. Techno-scientific scope: space and non space antenna electronics; field of application: space antennas to be used especially for TV signals. <IMAGE></p> |
