A Novel Ultra-Wideband Printed Monopole Antenna
نویسندگان
چکیده
In this paper, we introduce a novel printed monopole antenna for ultra-wideband (UWB) applications. The antenna is composed of two overlapped circular disc monopoles with a finite ground plane and fed by a 50 microstrip line. The designed antenna operates over impedance bandwidth (2.9 to 11.6GHz) for return loss S Ω 11 < -10dB. The antenna also shows omni-directional radiation patterns and good gain flatness over the frequency range of interest. The antenna group delay variation is less than 1ns and the time-domain pulse distortion is small which indicates that the proposed antenna performance is suitable for UWB applications
