摘　　要：在分析了单个微带圆环缝隙天线的基础上,设计和制作了一种Ku波段宽带微带圆环缝隙平面天线阵。整个天线阵分成9块进行独立设计,采用T型等分并联馈电网络单独馈电,最后利用一个圆形一分九威尔金森等分功分器连接组成天线阵总体。这种结构的平面微带缝隙天线阵阻抗带宽达到了20.56%(VSWR<2),增益达到34.5 dB,在卫星通信等领域应用前景广阔。Based on the analysis of single microstrip annular slot antenna,a broadband planar array of microstrip annular slot at Ku band is designed and manufactured. The whole array is divided into nine small arrays which are designed independently,then a circular 1： 9 Wilkinson splitter is employed to connect nine arrays to whole planar array. From calculated and experimental results, the obtained impedance bandwidth （VSWR〈2） reach 20.56 %, the gain reach 34.5 dB. The proposed planar array satisfies the use of satellite communications.
