摘　　要：雷达高度计天线工作于C/Ku双频段,采用1.2m反射面及C/Ku双频同轴馈源,该天线实现了高效率、低副瓣。采用C/Ku双频同轴馈源进一步降低了天线的结构尺寸和质量。测试结果显示天线完全达到设计要求。The antenna of radar altimeter works in C/Ku dual-band by using 1.2m reflector and C/Ku coxial feed.The antenna achieves the result of high gain,low sidelobe,low cross-polarization.The structure size and quality of the antenna are further reduced by using C/Ku dual-band coxial feed.The test results show that the antenna fully meets the design requirement.

关 键 词：同轴馈源 等化性 波束效率 高精度波束指向
