Abstract

Ultra wideband (UWB) is a new wireless communication system. It utilizes transmission signal at wide bandwidths. With wider bandwidth, it can provide for new useful applications. The first chapter in this thesis discusses the features and advantages of the UWB. Chapters 2 and 3 present two proposed UWB applications. Chapter 2 presents the use of UWB in shipping containers. The security of shipping containers is an urgent issue for globally. UWB can provide a solution to secure containers. Our goal is to develop a system to enhance the transmission signals. In comparison with other system designs, our waveguide approach satisfies most of the requirements. In chapter 3, we propose using UWB for medical implants. With its advantages, UWB provides benefits over other wireless systems. Our goal is to develop a method to find the optimal position for the UWB transmitting antenna and yield better performance. We proposed an equivalent circuit method, verified by finite element approaches, to simplify design methodology.
