Abstract :
Absolute gain and radiation efficiency are calculated using the finite-difference-time-domain (FDTD) method. The method described utilizes pulsed excitation, so that wideband results are available from a single FDTD computation. The approach is demonstrated for a simple wire antenna geometry, and is validated by comparison with results obtained using the method of moments
