Preface

Wireless communication systems demand higher data rates, enhanced quality of service, and more channel capacity. These features can be achieved by using Ultra Wideband technologies (UWB), which have attracted considerable attention in the last decade. The inherent features of UWB technologies are a high data rate, more channel capacity, extremely less power consumption, and low cost. Compact wideband RF modules and antennas are crucial in developing UWB direction-finding systems, radars, seekers, and communication systems. UWB systems suffer from losses due to multipath fading and frequency interference. Input Multiple Output (MIMO) technology can solve multipath interference and losses to improve the dynamic range and channel quality of the communication system.

This book discusses innovation in UWB technologies and systems. Each chapter presents important information to enable engineers, students, and scientists from all areas to follow and understand the topics presented in the book. The book is divided into four sections that present the main topics of green technologies.


Chapters in these sections examine such topics as UWB MIMO antennas and UWB RF modules and systems. Minimization of the size, cost, and weight of UWB RF modules and antennas is achieved by employing MMIC, MIC, and MEMS technologies. However, the integration of MMIC, MIC, and MEMS components and modules raises technical challenges in efficiency, accuracy, and tight tolerances. Accurate design of microwave modules and antennas is a must in the development of UWB systems, as it is impossible to tune microwave devices in the production line. The book also includes chapters on UWB technologies for medical and sports applications and time-domain performance evaluation of UWB antennas.

I want to thank all the chapter authors for their excellent contributions.
