ABSTRACT:
A double-reflector microwave antenna of the Gregorian optics family and capable of providing an elliptical beam with a major axis that may be oriented in any desired direction of space by rotation of the sub-reflector about an axis. By adding an additional degree of freedom, that is, an independent translation of the sub-reflector and/or the main reflector along respective axes, a considerable degree of reconfigurability of the shape of the beam may be realized. In particular, the axes of the beam may be widened to vary the ratio between the axes of the elliptical beam for any orientation of the major axis or to obtain a circular beam. The inventive antenna is particularly suitable for use as on board satellites with frequency re-use in an operational environment with one or more simultaneously active beams.
