Published purpose

The satellite market is currently shifting toward LEO constellations. Those new missions calls for phased array antennas which up to now are typically operating in single polarization. Combining two phased array antennas in a dual polarization operation represents a great advantage in terms of real estate and cost effectiveness, both aspects being crucial for satellite operators. The project purpose is to develop the necessary technologies to enable the combination of two polarization in one phased array antenna. This requires developing antenna architecture but also advanced Radio frequency (RF) components in order to maximize efficiency and reduce the electronic front end foot print. The expected outcome will be a reference architecture and electronics to support MDA’s new product line of dual polarization phased array antennas. Those LEO constellations will ultimately provide broadband access to remote parts where it is not economically viable to develop traditional broadband services and help closing the digital divide.
