Abstract

This paper discusses the history of ultra-wideband (UWB) wireless and considers spectrum issues. It deals with UWB signal sources, including step, impulse, monocycle and RF pulses. It introduces new NLTL technology which can generate 6 V, 4 ps pulses and which could be used for 10 Gbit/s, millimeter wave, UWB wireless LAN. Several UWB antennas are presented including conical, TEM horn, D*dot, monopole and waveguide horn. Experimental proof is given that UWB free space propagation is not wavelength-dependent.
