Abstract :
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.
