Abstract : A preliminary investigation is conducted on the selection of antenna configurations which have potential to be ultrawideband (UWB). Each configuration is summarized. This includes discussions of new results that are byproducts of the study, conclusions that are drawn from the survey, and recommendations that are made which are predicated on the research. With regard to approaches for characterizing UWB antennas, two overriding conclusions emerged from this effort: (1) the philosophical maxim, 'the proof of the UWB antenna is in its short pulse behavior,' should be implicit in any study, and (2) each campaign should be a synergistic merging of theoretical, numerical, and experimental methods. Based on the capability to enhance existing knowledge and understanding of the performance of UWB antennas, this study recommends the following topics be studied in greater detail: loaded dipoles, flared and notch antennas, helixes and spirals, fat antennas, arrays with mutual coupling, the possible reduction of phase variation in log periodic antennas, wide-angle biconical antennas, and antennas that are suitable for impulse radiation.
