摘　　要：描述了四线阵L波段宽带超低副瓣偶极子阵列天线的研制,给出了研制过程中所解决的如宽带偶极子天线单元研制、天线单元间互耦研究、空气板线精密行馈网络的CAD及电磁兼容设计、空气板线精密行馈网络制造和装配等多项关键技术及所采用的技术途径。文中给出了一些设计数据和测试结果。天线近场测试表明,所研制的天线在优于25%频带内天线副瓣峰值电平低于-37dB。The study and fabrication of a four element L-band wideband ultralow sidelobe dipole array is described. The import technologies including the study and fabrication of wideband dipole radiator, the studing of the mutual coupling of dipole rediator, the CAD and EMC design of the accuracy air-dielectric stripline row network, the fabrication and assembly of the accuracy air-dielectric stripline row network, and key technical method, are discussed. There are some design datas and test results in this paper. The wideband ultralow sidelobe dipole array have been examined by means of near-field over a 25% band, and the maximize sidelobe are below -37 dB.
