Abstract The time domain radiation characteristics of dipoles and V antennas are obtained by solving the time domain electric field integrodifferential equation with the time-stepping approach. The effects of positions of the feeding source, the amounts of distributed loading along the antennas and the lengths and angles of V antennas on the input urrents and far field radiation characteristics are analyzed. The results obtained show that the appropriats amounts of distributed loading will yield a far field waveform that exhibits a "time limited" characted, that the deviation of the feeding source will reduce the maximum instant field intensities, and that in order to obtain the maximum instant field intensities in the certain direction, the optimum design for the parameters, such as length and angle, of V antennas is needed.
