In this paper we present a simple Log-Periodic- Dipole-Arrays (LPDA) solution that allows us to achieve good Ultra-Wideband (UWB) performances. The antenna has been manufactured and the measurements agree well with the theo- retical predictions. The antenna presents an average gain of 8 dB and a return loss better than -10 dB over the band from 4.2 to 10.6 GHz. Both the measured antenna transfer function and the computed effect on pulse transmission show good performances in comparison with already known UWB antennas.

Abstract
In this paper we present a simple Log-Periodic- Dipole-Arrays (LPDA) solution that allows us to achieve good Ultra-Wideband (UWB) performances. The antenna has been manufactured and the measurements agree well with the theo- retical predictions. The antenna presents an average gain of 8 dB and a return loss better than -10 dB over the band from 4.2 to 10.6 GHz. Both the measured antenna transfer function and the computed effect on pulse transmission show good performances in comparison with already known UWB antennas.
