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.

卫星系统将信息网络的范围扩大到了任何其他通信系统都无法到达的最偏远的地方（远离城市和高速公路、海洋中央和太空深处）。此外，许多新兴的应用，例如飞行期间的飞机（机舱内信息娱乐服务）、汽车、公共汽车/救护车中的宽带通信，需要与当前称为SOTM（移动卫星或SOTM）的运动中的卫星通信。据MarketsAndMarkets预测，到2019年底，移动的卫星市场将从34.5亿美元（2015年）增长到56亿美元以上，年复合增长率为10.2%。最先进的高性能SOTM系统使用机械旋转天线或机械旋转结构与电子扫描系统的组合。这样的系统通常体积庞大且轮廓高，不能安装在空气动力学主体上，并且跟踪速度太慢。由于这些系统的尺寸/重量大和速度低，因此无法渗透到小型汽车和中小型飞机等更大的市场领域。拟议研究的主要挑战是开发一种低成本、低剖面和高度模块化的卫星天线技术平台，具有电子波束控制能力（没有机械移动部件），这将为广泛的移动的用户提供随时随地的宽带和可靠的通信。该技术基于滑铁卢大学智能天线和无线电系统中心（CIARS）正在研究的新相移概念，一旦开发出来，还将为许多新兴的卫星网络提供最具成本效益的解决方案，如OneWeb项目，旨在连接整个世界。
