Abstract
A phased array line feed for a reflector antenna, including a plurality of substantially parallel metallic rods and a phase/power switching matrix electrically connected to the metallic rods. The phase/power switching matrix may steer a beam of the reflector antenna by adjusting the phase and/or power difference between the metallic rods. The phased array line feed may also include a plurality of substantially parallel metallic disks. The metallic rods may extend through the metallic disks substantially perpendicular to the metallic discs. The metallic discs may be equally spaced and the diameter of the metallic disks may decrease along the length of the metallic rods. Alternatively, the diameters of the metallic discs may be equal and the distances between the metallic discs may decrease along the length of the metallic rods.
