摘要

研究了电流源在时域有限差分(FDTD)天线分析中的应用。结果表明，电流源激发的偶极子天线上的瞬态场比电压源激发的瞬态场衰减得更快。相反，对于环形天线，电压源激发的瞬态场收敛速度很快。并给出了带有电流源的天线的输入阻抗。

A study on current sources used in finite-difference time-domain antenna analysis

Application of a current source to antenna analysis using the finite-difference time-domain (FDTD) method is studied. It is shown that the transient fields on a dipole antenna excited by a current source decay more rapidly than those excited by a voltage source. Contrastingly, for a loop antenna transient fields excited by a voltage source converge quickly. The input impedance of antennas with a current source is also illustrated.
