Low-profile high-gain antennas for SOTM terminals with massive MIMO

为行驶在基础设施有限的偏远地区的移动汽车提供高速连接是未来卫星通信产业的一个有前途的应用领域。其中一个关键的技术挑战是为SOTM（移动卫星通信）终端开发低剖面、低成本、高性能的天线。现有的解决方案通常需要高的实现复杂性，这限制了它们在标准商用汽车中的应用。在这个研究项目中，我们建议开发有效的和低复杂度的SOTM天线的解决方案。我们的目标是实现可比的链路性能与传统的抛物面反射天线低得多的轮廓，没有机械跟踪部分。我们计划探索多天线传输和接收技术领域的最新进展，更具体地说，是大规模MIMO技术，以解决这一具有挑战性的设计问题。所提出的方法将自适应地利用大量的天线元件的瞬时信道状态信息的基础上，这有可能导致大大改善性能比以前提出的相控阵天线。从拟议的研究计划中开发的技术将直接应用于加拿大私营部门，并提高加拿大公司在移动的卫星天线领域的竞争优势。

Providing high speed connection to moving cars driving through remote area with limited infrastructure represents a promising application area for future satellite communication industry. One of the key technical challenges is to develop low-profile cost-effective high performance antennas for SOTM (Satcom-On-The-Move) terminals. Existing solutions typically entails high implementation complexity, which limits their application to standard commercial cars. In this research project, we propose to develop effective and low-complexity solutions for SOTM antennas. The objective is to achieve comparable link performance with conventional parabolic reflection antennas with much lower profile and no mechanical tracking parts. We plan to explore the recent advanced in the area of multiple antenna transmission and receiver technologies, massive MIMO technologies more specifically, to address this challenging design problem. The proposed approach will adaptively utilize a large number of antenna elements based on their instantaneous channel state information, which has the potential to lead to much improved performance than previously proposed phased array antennas. The technology developed from the proposed research program will be directly applied to Canadian private sector and enhance the competition advantage of Canadian company in the field of mobile satellite antennas.
