| 摘 要： | 主要研究了对数周期偶极子天线.基于Pocklington积分方程和全域基函数,采用矩量法结合网络理论建立了天线算法模型;使用该模型计算了在天线阵和集合线共同作用下天线的辐射方向图,得出了集合线在不同频段上对天线辐射性能的影响,并通过截短延长线长度改善了天线低频段的辐射特性,增强了天线轴向方向性.

| Abstract: | The log periodic dipole antenna(LPDA) is used as an object of study.Based on the Pocklington integral equation and the whole wise function as the expansion,the mathematic model of LPDA is established by the means of moment(MoM) as well as the network theory.This model can calculate the directional pattern of LPDA on which both antenna array and feederline act,and help understand the effect of the feederline on the directional pattern of antenna when the deederline is in different frequent bands.Meanwhile the directional pattern of LPDA in the low frequent band is improved by shortening the length of stub. |
