Multi-feed reflector antennas (MRAs) with suitable beamforming networks (BFNs) are the preferred solution for satellites in the geostationary orbit (GEO), since the GEO requires narrow beams with a limited scan range. For satellites in a low Earth orbit (LEO) direct radiating phased arrays can be attractive, since wider beams with larger scan angles are(More)
