ABSTRACT:
A single antenna array having a phase shifter at the input of each antenna lement and fed by a multifrequency input for simultaneously generating at least two beams. When the different excitation frequencies are simultaneously inputted into the phase shifters, a separate phase increment is introduced into each radiator for each frequency. The result is a separate beam output from each frequency input, the beams being generated simultaneously but at different beam pointing angles.
