Abstract: A scanning beam transmit antenna system includes a source of electromagnetic energy, radiating elements and a feed network connecting the source to the radiating elements. A beam steerer controls the phase of the electromagnetic energy at each of the radiating elements. Power dividers route the electromagnetic energy to each of the radiating elements, and switches control the flow of the electromagnetic energy among the power dividers. The beam steerer changes the phases of the energy emitted by the radiating elements as a function of time to cause sequentially a motion of the scanning beam in the "TO" direction and a motion of the scanning beam in the "FRO" direction, and the switches modify the flow of the electromagnetic energy through the power dividers to and among the radiating elements on one half of the linear array during the "TO" motion of the scanning beam and to the radiating elements on the other half of the linear array during the "FRO" motion of the scanning beam.
