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 . |
