摘要
介绍了一种用于卫星地面移动通信系统的相控阵天线。该天线采用GPS与电子罗盘相结合的跟踪控制方案，控制天线波束在仰角30°～90°，方位角0°～360°的空域内快速扫描，自动跟踪通信卫星，确保话音通信和数据传输。增益优于14dB，圆极化工作，天线工作在L波段，直径小于550mm。介绍了单馈源双频圆极化天线单元、波束控制器的理论分析和工程设计，以及天线系统的组成和主要性能。实测结果表明该天线能够满足卫星地面移动通信终端的应用。
This paper presents a design of phased array antenna system for mobile communication system. It can scan the communication satellite automatically from 30° to 90° in elevation and 360° coverage in azimuth. Its antenna gain is better than 14 dB and diameter is less than 550mm. This paper gives theoretical analysis and engineering design of the single - feed circularly polarized micro - strip antenna and the control system. The results indicate that the phased array antenna system is fit for the mobile ground terminal of satellite communication system
