| 摘 要： | 为减小和差矛盾和完善毫米波多模自跟踪反射面天线的系统性能 ,在带宽范围内进行了矩形波导七模馈源的设计。矩形波导七模馈源的结构比较复杂 ,模比及相位难以控制 ,但采用理论计算结合 HFSS软件仿真的设计方法 ,仅需加工一次 ,即可得到满足要求的毫米波多模自跟踪馈源。对整个天馈系统的测试结果表明 ,与理论完全吻合 ,其工作带宽、旁瓣电平、零深、和差矛盾等指标都优于理论值

| Abstract: | The design of a millimeter wave multimode feed horn for use in a monopulse feed system is summarized.The feed horn employs seven modes in the rectangual waveguide,which improves the performance of the multimode autotrack antenna having a paraboloidal reflector.A major design task is to obtain the proper mode content ,the mode ratio and the associated matching sections.In order to reduce the contraction of machining,the method of theoretical analysis combined with an emulational computation using HFSS tools is introduced.The measured quantity agrees fairly well with the value in theory. |
