SATSOFT Dual Mode Optimizer

Multi-beam antenna designs which must accommodate a non-contiguous output multiplexer require two independent ports on the antenna. These ports generate shaped beams with complete or partial overlap, thus requiring one or more shared feeds.

Using this option with SATSOFT, two feed networks are synthesized to generated the desired beamshapes. During optimization, the feed excitations are constrained to be orthogonal, which is necessary for lossless realization.
