## Abstract A fully integrated CMOS ultraβwideband (UWB) transmitter module is proposed for UWB applications. The transmitter module consists of a bandβnotched UWB antenna and a transmitter IC which integrates a pulse generator, a gating signal generator and driver amplifiers (DAs). The drive ampli
cations in the complex wave propagation environment. Similar radiation patterns for other frequencies over the operating band were also seen, and the results are not shown for brevity. Measured peak antenna gain and simulated (Ansoft HFSS) radiation efficiency versus frequency is shown in Figure 4.
