Original Kurzfassung:
In this paper we present an ultra wideband (UWB) test set-up with a novel low-cost microstrip
pulse forming network for Gaussian monocycle generation. The test set-up consists of a
commercially available pulse generator, a novel low-cost pulse forming network, a prototyped
wideband balun, different wideband antennas and a sampling oscilloscope. The combination of
pulse generator and pulse forming network generates a monocycle pulse with an amplitude of
1.8 Vpp and a time duration below 300 ps. This unbalanced pulse is transformed to a balanced one,
by a wideband CPW-to-CPS balun, to feed different types of balanced wideband antennas. The
radiated pulse is received by an equivalent antenna-balun combination. The signal processing for
the determination of different target position was carried out by correlation algorithms.
