Qurratulain, Neela Chattoraj . Effect of Ground plane on a tapered U slot Ultra Wideband Antenna. International Conference on Communication, Circuits and Systems 2012. IC3S, 2 (June 2013), 8-11.
This paper presents the design and results of a compact tapered U slot UWB printed monopole microstrip antenna. The planar, very small, thin UWB antenna fed by a single 50? microstrip line with truncated ground plane is excited by a coaxial SMA connector. The simulation was done using Ansoft High Frequency Structure Simulator (HFSS) software. Extensive investigations and parametric analysis is also carried out on the same radiator design by varying the dimensions of the ground plane and study the effect on UWB performance parameters. The antenna is fabricated and the measured impedance bandwidth defined by VSWR<2 obtained is 10. 46GHz(3. 54-14GHz) for partial ground plane size and a narrow band is obtained for infinite ground plane size respectively. The simulated results of impedance bandwidth, radiation patterns and group delay are well supported by measurement.
