The authors have drawn together studies on compact and directive antennas for radiating fast transient fields. The TEM structures described give a class of suitable antennas including fins and horns. Features of resistive loading and other types of termination are considered. The farfield properties of these antennas can be related to the source waveform: the radiated electric field is approximately proportional either to the source waveform or its derivative. Bicones and fins follow the time history of the source, whereas horns differentiate in the farfield. In order to maximise the radiated farfield strength three factors must be considered in horn design: planarity of the wavefront at the mouth of the horn, maximal width at the mouth, and minimisation of the reflection from the termination.
