Abstract (en)

An aspect of the invention concerns a satellite antenna (SA) comprising a planar reflector (PLA), a feedarm (FDA) attached to the planar reflector (PLA) by attaching means (AM); an antenna feed (ANF) attached to the feedarm (FDA) such as to receive the signal focused by the planar reflector (PLA). The planar reflector (PLA) comprises a continuous metallic layer acting as a ground plane and a plurality of conducting patches, said plurality of patches being designed so that the signal reflected by the planar reflector (PLA) is focused to a given focal region, and arranged in one or more layers, such layers being separated among them and from the ground plane by one or more other layers of insulating materials. Furthermore, the attaching means (AM) used to attach the feedarm (FDA) to the planar reflector (PLA) are arranged to allow the feedarm (FDA) to be moved independently from the planar reflector (PLA) so as to position the antenna feed (ANF) in the focused region of the reflected signal.
