Phased Arrays in Waveguide Technology for Low Earth Orbit (LEO) Active Payloads

This article presents a new design approach for LEO spaceborne phased arrays, which is based on full-metal miniature horns. Such new approach is characterized by better radiation efficiency and easier industrialization than other examples in the state-of-the-art. The approach has been validated in both Ku- and Ka-Band, including RF experiments with and without beamforming and environmental derisking.
