摘要

对工作在x波段的4×4发射型有源集成天线阵列(AIAA)和2×2接收型带到达方向函数阵列的微波组件、样机进行了演示。卫星星载跟踪系统的组成部分采用薄基片制作了宽带高增益低噪声放大器(LNA)和紧凑平面天线。为实现良好的卫星跟踪系统,实现了发射信号与接收信号之间的高度隔离。实测天线方向图与理论天线方向图吻合较好。

The prototypes of X-band active integrated antenna array for a satellite on-board tracking system
Microwave components, prototypes of 4×4 transmitting active integrated antenna array(AIAA) and 2×2 receiving array with direction of arrival function operating at the X-band were demonstrated in this paper. For the components of the satellite on-board tracking system, a wideband and high gain low noise amplifier (LNA) as well as the compact planar antenna were fabricated using thin substrates. High isolation between the transmitting signal and the receiving signal was achieved for the good satellite tracking system. Good agreement on measured antenna patterns with the theoretical ones was obtained.
