摘　　要：在散射通信系统中采用角分集天线,可使原来两副天线才能完成的任务通过一副天线就能实现,减少系统的天线数量、降低成本,同时还可以减小设备体积和重量、增加系统的机动性。研制了一款Ku频段的散射角分集天线,开展了135 km链路的角分集测试试验,得到的角分集相关系数小于0.6,满足进行分集接收的条件,为散射角分集通信设备的研制奠定了技术基础。To meet the requirement of the dual-polarized light antenna for the new band troposcatter communication,the research of the X-band double polarized carbon fiber antenna is proposed.The antenna aperture is fabricated by carbon fiber material which can insure the electrical performance and reduce the whole antenna weight.The software HFSS is used to simulate and optimize the antenna.Based on the results of design and simulation,the antenna prototype is fabricated,and the test is conducted. The obtained polarization isolation is larger than 40 d B which is better than the dual-polarized troposcatter communication design requirement.
