A bidirectional array antenna system is disclosed, of series feed type, which provides two differently directed arrays each capable of forming and steering transmit and receive beams through an angular sector, and which requires but a single set of elemental phase shifters and drivers for forming and steering the two beams. This is accomplished by bilateral use of the elemental phase shifters in the beamforming operations of both arrays while maintaining isolation between arrays by use of the characteristic orthogonality of series feeds to wave energy with phase gradients unmatched to the feed. The two beams may be thus formed and steered either simultaneously or in time alternation, through the angular sectors for which the respective arrays are oriented.
