Abstract :
In an innovative measurement approach time domain antenna characterization has been combined with full 3D radiation pattern characterization. With this approach transient antenna responses can be measured over the entire hemisphere and hence the antenna under test can be comprehensively characterized for UWB impulse applications in both time and spatial domain. The method has been applied to a Vivaldi and a bow-tie antenna. It has been shown that both antennas concentrate energy in the time domain very well and provide a large coverage area with slightly higher directivity of the Vivaldi antenna.
