V型天线的行波加载公式

The Loading Formula for V-type Travelling Wave Antenna

本文研究了ｖ型天线上电流分布与阻抗加载的关系，导出了支持天线上行波电流的阻抗加载公式。讨论了天线张角、振子半径以及振子长度与加载量的关系和规律，说明了加载Ｖ型天线的宽带特性。文中还计算了在高斯脉冲激励下，不同加载量的天线上瞬态电流的分布，由此可以表明所导加载公式的正确性与重要性。

By studing the relationships between the current distributions and the im￣ance hoings on the Vtype antenna,here proposed a loading formula to determine the quantities of the lOading which can sustain a travelling-wave current along the antenna.The characteristics of the loading against frequency with different span angles,radii and lenthes of the V-tin antenna are also discussed in the paper,which could show the broad bandwidth properties Of the loaded antenna.Furthermore,the transient current distributions on the antenna with differedt hoings are discussed as wen when the excitation is the Gaussian pulse,which could prove of the importance and rightes Of the deduced formula.
