In this paper a novel antenna array structure with UWB properties is presented. This structure satisfies the European UWB regulations and is suitable for Radar applications. A differential feeding structure is applied to the array, in order to decrease the coupling between the elements and the cross-polarization. The array is characterized by a good time and frequency domain behaviour.
