It is di-cult to determine the feed radiation center and F/D of the re∞ector impulse-radiating antenna (IRA) in frequency- domain, due to its ultra-wideband (UWB) property. This paper presents an e-cient approach to design the re∞ector IRAs, via evaluating the transient radiation patterns (TRPs) of the feed for some given difierent radiation centers. Only one time-domain simulation for the feed is needed in this method. Comparing with the global optimization algorithms, our method is fast and reliable in the design of the re∞ector IRAs.
