The final report contains the results of an investigation to use the concepts of radiation from accelerating charges to develop the radiation characteristics of pulse-excited antennas in the time domain. The transition to antennas is accomplished through derivation of a radiation equation involving the time-derivative of the antenna currents. For sinusoidal time variation this equation reproduces well-known results for a number of common antennas. For pulse-excited linear antennas, the radiation equation produces a result derived previously by retarded potential and other methods. Numerical comparison with a published frequency-domain analysis of a pulsed dipole shows reasonable agreement except for angles close to the end-fire direction.
