Abstract :
Results are presented showing antenna pattern reconfiguration using an electronically controlled surface. Spot-beam and shaped-beams have been generated and excellent agreement was found between predicted patterns and those measured at 10 GHz with a compact antenna range. The antenna comprises an 85-cm-diameter offset reflector fed from a 30 degrees corrugated horn. As an example of a typical shaped-beam, a template was chosen corresponding to a scaled version of an INTELSAT requirement.<>
