Abstract

There is provided a feed system for at least one antenna array, the at least one antenna array comprising a plurality of fixed antenna elements arranged in at least one substantially circular array about an axis, the feed system comprising a substantially planar rotating member rotatable about the axis, the rotating member having a circular edge and comprising a radiating unit adapted to radiate power towards the edge, the radiated power escaping the rotating member at the edge; and a connecting member interconnecting the rotating member to the plurality of antenna elements, the connecting member having a circular shape and positioned about the edge of the rotating member in spaced relationship therewith, the at least one antenna array positioned adjacent the connecting member with the at least one antenna array, the rotating member, and the connecting member concentric about the axis, the connecting member adapted to guide the radiated power escaping the rotating member towards the plurality of antenna elements.
