Integrated circuit and antenna technologies for low-cost ka-band phased array system for satellite communication on-the-move

卫星通信市场正在迅速增长。近年来，更高频率的Ka频段(20/30 GHz)系统的可用性和高潜力导致了对该技术的巨大投资。目前，大多数地面终端安装在固定位置。然而，一些现有和新兴的卫星网络服务，如宽带卫星互联网、卫星新闻采集、灾后恢复通信系统、远程医疗、应急系统和国防应用，都需要半移动或全移动地面终端(Satcom on-the-Move或“SOTM”)才能充分发挥其潜力。尽管在这一领域开展了广泛的研发和商业活动，但开发的SOTM系统要么极其昂贵，要么不能满足所有需要的要求。

The satellite communication market is rapidly growing. Availability and high potential of higher frequency Ka-band (20/30 GHz) systems in recent years, have led to huge investments in the technology. Currently, the majority of ground terminals are installed in fixed locations. However, several existing and emerging satellite-based network services such as Broadband Satellite Internet, Satellite News Gathering (SNG), Communication Systems for Disaster Recovery, Telemedicine, emergency systems and defence applications require semi-mobile or fully mobile ground terminals (Satcom On-The-Move or "SOTM") to reach their full potentials. Despite extensive R&D and commercial activities in this area, the developed SOTM systems are either extremely expensive or do not meet all the needed requirements.
