【摘要】 描述了一种C频段宽带超低副瓣平面阵列天线的设计,给出了设计过程中所解决的如宽带天线单元设计、阵面布局及激励优化、带状线精密并馈网络的设计、阵列馈网一体化设计等多项关键技术及所采用的技术途径。文中给出了模型的设计数据和测试结果。天线远场测试结果表明,所研制的天线在20%的带宽范围内,可以实现增益(Gain)>18.1dB、H面方向图副瓣电平(SLL)<-26.2dB、前后比(FBR)<-33.8dB。更多还原

【Abstract】 This paper describes the design of a C band broadband low sidelobe planar array antenna, and presents several key technologies such as wideband antenna element design, array layout and excitation optimization, strip line precision feed network design, array feed network integration design and the technical approaches adopted in the design process. Some design data and test results of the model are given in this paper. The antenna remote field test results show that the developed antenna can achieve Gain>18.1 dB, side lobe level(SLL) <-26.2 dB and front to back ratio(FBR) <-33.8 dB within 20% bandwidth range.更多还原
