This comprehensive summary of the state of the art in Ultra Wideband (UWB) system engineering takes you through all aspects of UWB design, from components through the propagation channel to system engineering aspects. Mathematical tools and basics are covered, allowing for a complete characterisation and description of the UWB scenario, in both the time and the frequency domains. UWB MMICs, antennas, antenna arrays, and filters are described, as well as quality measurement parameters and design methods for specific applications. The UWB propagation channel is discussed, including a complete mathematical description together with modeling tools. A system analysis is offered, addressing both radio and radar systems, and techniques for optimization and calibration. Finally, an overview of future applications of UWB technology is presented. Ideal for scientists as well as RF system and component engineers working in short range wireless technologies.

The book provides an empirical analysis of the factors that determine the employment impact of environmental innovations. The multivariate estimations are based on a methodology taking direct and indirect employment effects on the firm level into account. The data are derived from interviews with more than 1500 firms in Germany, Italy, the Netherlands, Switzerland, and the UK specifically conducted for this analysis. In addition to the empirical study based on interviews, case studies from five selected business sectors are used to provide profound insight in the environmental innovation behaviour of the firms.
