This research proposes a compact elliptical ring antenna excited by a circular disc monopole (CDM) for ultra-wideband (UWB)\ncommunications. In the study, time- and frequency-domain pulse distortions of the antenna in the transmission mode were\ncharacterized by magnitude and phase of the antenna transfer function (Hrad). The results showed that the gain and magnitude of\nHrad in the boresight direction are sufficiently flat with linear phase response. The average antenna gain is 3.9 dBi over the UWB\nspectrum.............................
