    摘要:

    基于矩量法研究半波振子天线的电流分布。在矩量法计算天线电流过程中,基函数选用脉冲函数,权函数选用局域高斯函数,得到半波振子天线辐射的E面方向图。结果显示,该方向图与CST数据后处理法和天线电流驻波理论的结果完全重合,并且矩量法比CST数据后处理法具有明显的节约时间的优点。

    Abstract:

    The current distributions of the half wavelength dipole thin antenna along the wire are numerically calculated with our proposed Method of Moment(MOM),CST-based method, and then visualized by Matlab figures. The results on the current distributions have shown that Method of Moments (Pulse-Gaussian Method of Moments) was validated by CST- based method and standing wave method (theoretical approximation method). The radiation pattern of the antenna is drawn vividly according to the current distribution calculated by three methods. The simulated result by our MOM has a time-saving advantage over that by CST-based method with the same accuracy.
