摘　　要：宽带空地通信系统(ATG)是民航客机外部通信系统的重要通道之一,能够为旅客和机组提供宽带通信服务,而MIMO天线技术有望在其中发挥关键性的作用。然而,空地通信环境与地面移动通信环境差别迥异,现有的地面移动通信中的天线技术需要经过适应性改进,才能达到系统性能要求。因此,针对ATG的特殊通信环境,结合MIMO技术的应用条件,研究ATG系统中天线设计的要点、难点,着重分析机载端天线的选型要求,以期对今后工程实现提供借鉴。ATG （Air-to-Ground wideband communication system） , as one of the critical external communication systems for civil airplanes, could provide wideband access service for passengers and crews, while MIMO antenna technology may play a pivotal role in this ATG system. However, the existed terrestrial mobile communication system must be transformed to meet the ATG technical requirements due to the significant difference on radio environment of between terrestrial mobile and ATG. For this reason, design essentials and nodus are studied in combination with the application premise of MIMO within ATG radio circumstances. In particular, the technical requirements of airborne antenna are emphatically analyzed, this would have certain guiding significance to the future engineering implementation.
