Abstract :
Directional ultra-wideband antennas in various planar technologies are described. All designs feature a parabolic-shaped ground plane to accomplish high directivity and gain. Moreover, in comparison with a simple corner-shaped ground plane, the parabolic ground plane enhances bandwidth and improves input return loss. It also contributes to antenna compactness and efficiency in radar tracking applications. The salient features of the UWB antenna designs are demonstrated through two different full-wave simulation packages in the time and frequency domains.
