摘要
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块独立设计,采用并联馈电网络,利用圆形一分九威尔金森功分器连接组成整个天线阵。这种结构的平面阵阻抗带宽达到了20.56%(VSWR<2),增益达到34.5dB,满足卫星通信等领域的应用。
A broadband planar array of microstrip annular slot in Ku band is designed and manufactured. The whole array is divided into nine small arrays which are designed independently,and 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) reaches 20.56% ,and the gain reaches 34.5dB. The proposed planar array satisfies the use of satellite communications.
