In this paper, authors present a time-domain performance analysis and comparison of various band-notch techniques that are popularly used in UWB antennas. Three different band-notch techniques are implemented to a reference UWB antenna to realize a band-notch behavior at WLAN band. The antennas are analyzed in both frequency domain and time domain. The present study explores time-domain behavior i.e. pulse distortion and ringing due to band-notched techniques to UWB antennas.
