For impulse radio ultrawideband communications an ldquoantenna plus generatorrdquo system is co-designed and an on chip generator is integrated into the antenna. This approach does away with the need for intermediate transmission lines conventionally placed between an RF device/generator and an antenna and therefore eliminates the need for a balun, prevents excitation of the common-mode currents and...
In Haddad et al. (2004), we have shown that it is feasible to design filters with arbitrary waveform responses and therefore we propose an ultra-wideband pulse generator incorporating a filter with a Daubechies' impulse response (i.e. maximally flat over the desired frequency range). This pulse generator is co-designed with wideband antennas. An eight-order Pade approximation of its transfer function...
