This book presents state-of-the-art technologies, trends and applications with a focus on the healthcare domain for ultra-wideband (3.1–10.6 GHz) and 60 GHz (57–66 GHz) wireless communication systems. Due to various key features such as miniaturized antenna design, low power, high data rate, less effects on the human body, relatively less crowded spectrum, these technologies are becoming popular in various fields of biomedical applications and day-to-day life.
The book highlights various aspects of these technologies related to body-centric communication, including antenna design requirements, channel modeling and characterization for WBANs, current fabrication and antenna design strategies for textile, flexible and implanted antennas. Apart from the general requirements and study related to these frequency bands, various application specific topics such as localization and tracking, physical activity recognition and assessment, vital sign monitoring and medical imaging are covered in detail. The book concludes with the glimpses of future aspects of the UWB and 60 GHz technology which includes IoT for healthcare and smart living, novel antenna materials and application of machine learning algorithms for overall performance enhancement.

This book describes a new concept for analyzing RF/microwave circuits, which includes RF/microwave antennas. The book is unique in its emphasis on practical and innovative microwave RF engineering applications. The analysis is based on nonlinear dynamics and chaos models and shows comprehensive benefits and results. All conceptual RF microwave circuits and antennas are innovative and can be broadly implemented in engineering applications.

This book explores innovations in indoor positioning systems (IPS). The book explores novel localization techniques for unmanned aerial vehicles (UAVs) and discusses the development of radio frequency (RF) IPS modules and printed antennas. The book discusses how MIC (Microwave Integrated Circuits) and MMIC (Monolithic Microwave Integrated Circuits) technologies can be employed in developing RF devices, including transmitters and receivers for IPS systems. Microstrip mono-pulse antennas are presented as effective tools for determining position and direction in both IPS and radar systems.

This book disseminates some of the latest scientific and technological contributions by different researchers around the world in the development of both devices and applications based on Ultra-wideband (UWB) technology. Antennas, filters, resonators, delay cells, and transmitters are some of the useful electronic devices or systems described. The book will be a valuable source of information for undergraduate and graduate students, as well as for experts and researchers around UWB technology.

An important historical look at the space program's evolving telecommunications systems
Large Antennas of the Deep Space Network traces the development of the antennas of NASA's Deep Space Network (DSN) from the network's inception in 1958 to the present. It details the evolution of the large parabolic dish antennas, from the initial 26-m operation at L-band (960 MHz) through the current Ka-band (32 GHz) systems. Primarily used for telecommunications, these antennas also support radar and radio astronomy observations in the exploration of the solar system and the universe. In addition, the author also offers thorough treatment of the analytical and measurement techniques used in design and performance assessment.
