Shaped beam antenna, with single or double reflector, gridded or non-gridded, the shaped beams, which can rotate the polarisation, independent of the polarisation of the feed cluster, for use preferably aboard satellites and in micro-wave antennas. The antenna includes a reflector (1), one or more polarisers (2), (2a), one or more feed clusters (3), (3a) , microwave circuits (4), (4a) to set-up the BFN, input port (5), (5a), and connections (C) and (C1).
