Vallecchi, "Modular hybrid architecture for a large aperture circularly polarized
shaped-beam antenna," EuMA: 39th European Microwave Conference, 755-758, 2009.
Specifically, the microwave components include advanced multibeam antennas,
shaped-beam antennas, shaped reflector antennas, an active phased-array fed and direct radiating antennas, MMIC beam-forming networks, microwave switch matrices and solid-state power amplifiers.
