Abstract : The radiation of transient signals is studied to determine what conditions antennas must satisfy to minimize the distortion contributed by the antenna. The conditions suggest the use of V configured traveling wave antennas which appear to satisfy to a large degree the conditions necessary for good transient performance. Studied in particular are a cylindrical antenna with tapered resistive loading to achieve an outward traveling wave current distribution, and a new antenna consisting a high-conductivity cylinder terminated by a resistively loaded end-section. The current distribution, input admittance, and the terminal voltage for an impulsive incident field are calculated numerically for these antennas and the numerical results are verified experimentally.
