ABSTRACT:
Disclosed is an apparatus which reduces the number of phase shifters required in an antenna array. This is accomplished by supplying standing waves from the phase shifters to each of the radiating elements in a column or row. The standing waves in the rows are orthogonal to the standing waves in the columns. Each of the radiating elements combines the applied standing waves, the phases of which determine the angle of the resultant beam.
