ABSTRACT
Chapter 1 focuses on an overall introduction to UWB systems, including an historical perspective through to the most recent applications of UWB technology. Chronological growth of UWB technology, starting from the spark-gap realization of electromagnetic waves by Heinrich Hertz, is systematically presented with a special emphasis on landmark inventions/achievements in the area. Introductory definitions of UWB systems and various schemes to realize UWB technology are presented, followed by a discussion on spectrum regulation and applications; which together constitute a solid background for the reader, in particular those new to this area.
