Three Dimensional Phased Array Antenna for Communications with Satellite Constellations

Many companies have the projects to launch a lot of small satellites into the low Earth orbit in order to build the worldwide internet services. The ground stations are required to communicate simultaneously with several satellites. It is impossible for the parabolic antenna to track simultaneously several satellites. Therefore, we are newly developing a ground receiving station using the 3-dimensional Phased Array Antenna and the Digital Beam Forming technologies. The purpose of this study is to realize a worldwide receiving antenna network to communicate simultaneously with several satellites and to get information in real-time through the internet anytime and anywhere. We already built the pilot models of the receiving antenna at the frequencies of X-band and S-band, and succeeded in receiving the signal from the satellites.
