摘　　要：针对卫星X波段通信系统大范围数据传输的需求,设计具备高增益圆极化可宽角度电扫的星载相控阵天线。此天线阵元采用底馈的馈电方式,利用切角技术实现圆极化,利用开槽技术实现小型化。天线阵列错层排布,使其整体的辐射性能最优化。通过发射组件模块、波束控制模块和电源模块的合理布局和设计优化,使其电扫波束可在离轴角0~60°、方位角0~360°内变化。此单机经加工后测试结果良好,对X波段通信系统尤其是相控阵天线的设计有一定的指导意义。A spaceborne phased array antenna with high-gain,circular polarization and wide-angle is designed to meet the requirements of large range data transmission of X-band communication system.The antenna array element is fed by the bottom feed,the circular-polarization is realized by the angle cutting technology and the miniaturization is realized by the slot technology.The array is arranged in staggered layers,so that the radiation performance is the best.Through reasonable layout and optimization design of transmitting module,beam control module and power module,the beam can be changed within 0~60°off-axis angle and 0~360°azimuth angle.The test results of this machine are good after machining,which has a certain guiding significance for the design of X band communication system,especially the phased array antenna.
