摘要
The present invention relates to an array phasing technique which normally provides directional spotbeams, and in the event of a failure mode of a phase shift controller for providing a wide area coverage beam. In an arrangement for practicing the present technique, each array feed element has disposed at its input a serial arrangement of a fixed value phase shifter (32) and a variable phase shifter (34). Each variable phase shifter has a separate control signal supplied to it by a phase shift controller (36). During normal operation the combined fixed value and variable phase shifters cause the array to radiate a flat wavefront in a predetermined direction, and in a failure mode of the phase shift controller the fixed phase shifters cause the array to radiate a diverging area coverage beam.
