Abstract:

A 3-D DomeRotman Lens Antenna system is described which offers the capability for greater than hemisphere scan coverage from a single feed array, greater than octave bandwidth, and multiple simultaneous beams. The history and selected results of related programs are included. Results of the analysis performed show peak phase errors of 15 degrees for scanning in the major axis planes. This error level would produce about 28 dB peak sidelobe levels for low sidelobe distributions. Complete descriptions of the analysis, computer programs and results are included.
