A Review of Multibeam Phased Array Antennas as LEO Satellite Constellation Ground Station

Small satellites in low Earth orbit (LEO) are typically organized as a satellite constellation. The satellite number of a LEO satellite constellation would be several hundred or even tens of thousands to realize a fully global coverage. This imposes a big challenge on ground station for satellite or...
