ABSTRACT:
A network (26) for feeding a planar array of radiating antenna elements using row beamformers (28) and column beamformers (30) is made to project multiple contiguous antenna beams in a triangular pattern (22). The row beamformers (28) couple to the column beamformers (30). Phase shifting networks (46) are interposed between the row beamformers (28) and column beamformers (30) to apply a phase slope that distributes up to 180.degree. of phase shift across alternating rows of row beamformers (28).
