Integrated modular phased-array system technology for next generation satellite communication

Satellite systems have extended the boundaries of information networking to the most remote places (far from cities and highways, in the middle of the ocean, and deep in space) far beyond the reach of any other communication systems. In addition, many emerging applications such as broadband communication in the aircraft during flight (in-cabin infotainment services), car, buses/ambulances, require communicating with satellite in motion currently referred to as SOTM (Satellite-On-The-Move or SOTM). According to MarketsAndMarkets forecast the mobile satellite market is growing from $3.45 billion (2015) to more than $5.6billion by the end of 2019, at an annual compound rate of 10.2%. The state-of-the-art high performance SOTM systems use mechanically rotating antennas or a combination of mechanical rotating structures with electronic scanning systems. Such systems are often bulky and high profile, cannot be mounted on aerodynamic bodies, and too slow in tracking. Due to large dimensions/weight and low speed, these systems cannot penetrate much larger market sectors of smaller cars and small-to-medium size aircrafts.The main challenge addressed in the proposed research is to develop a low-cost, low-profile, and highly modular satellite antenna technology platform with electronic beam-steering capability (no mechanically moving parts), which will provide a wide range of mobile users with broadband and reliable communication everywhere and anytime. The proposed technology is based on a new phase-shifting concept under investigation at the University of Waterloo's Centre for Intelligent Antenna and Radio Systems (CIARS), and once developed will also offer the most cost-effective solution to many emerging satellite networks, like OneWeb project, which are aimed at connecting the entire world.
