摘要
文中对宽带伞形印刷振子进行了研究,并利用该结构的振子组成一个4×16平面阵列天线。根据该天线设计的特殊要求,需要对高低角方向图加以赋形。通过采用数值方法来优化列上的馈电电流的幅度和相位,使天线阵列的高低角方向图在指定的范围内满足赋形要求。
In this paper,Broadband umbellar printed dipole are studied and a 4×16 planar array antenna is developed on the bassis of it.According to the special performance of the antenna,the directivity pattern in vertical plane need to be shaped.By optimizing the amplitude and phase of the feed current along the column with the digital calculation method, make the directiviry pattern meet the demand in the oppointed ared.
