Combining analytic theory and modern computer-aided design techniques this volume will enable you to understand and design power transfer networks and amplifiers in next generation radio frequency (RF) and microwave communication systems. A comprehensive theory of circuits constructed with lumped and distributed elements is covered, as are electromagnetic field theory, filter theory, and broadband matching. Along with detailed roadmaps and accessible algorithms, this book provides up-to-date, practical design examples including: filters built with microstrip lines in C and X bands; various antenna matching networks over HF and microwave frequencies; channel equalizers with arbitary gain shapes; matching networks for ultrasonic transducers; ultra wideband microwave amplifiers constructed with lumped and distributed elements. A companion website details all Real Frequency Techniques (including line segment and computational techniques) with design tools developed on MatLab. Essential reading for all RF and circuit design engineers, this is also a great reference text for other electrical engineers and researchers working on the development of communications applications at wideband frequencies. This book is also beneficial to advanced electrical and communications engineering students taking courses in RF and microwave communications technology. www.wiley.com/go/yarman_wideband

Ultra Wideband (UWB) is the hot new topic in wireless communication engineering today. High-speed communication over short distances using sub-nanosecond pulses, rather than conventional sinusoidal waves, has paved the way for cheap wireless transceivers, capturing the imagination of both academics and engineers in industry alike. Ultra Wideband Signals and Systems in Communication Engineering focuses on the basic signal processing that underlies current and future ultra wideband systems ensuring this text will be essential reading even as UWB applications mature and change or regulations regarding ultra wideband systems are modified. Provides everything you need to know about Ultra Wideband Communications in one compact volume Explains, in an easy to understand manner, the basics of UWB and its applications Covers, in detail, the generation of UWB waveforms through to the position and location of UWB signals Discusses the issues that must be solved for UWB devices to explode onto the consumer communication market Includes examples and problems in each chapter to aid understanding Features a companion website including Solutions manual, Matlab programs, Electronic versions of the figures and a sample chapter This enlightening text is a must for senior undergraduates and postgraduate students interested in studying UWB, and the emphasis on UWB development for commercial consumer communications products means that any communication engineer or manager cannot afford to be without it!

Providing up-to-date material for UWB antennas and propagation as used in a wide variety of applications, «Ultra-wideband Antennas and Propagation for Communications, Radar and Imaging» includes fundamental theory, practical design information and extensive discussion of UWB applications from biomedical imaging, through to radar and wireless communications. An in-depth treatment of ultra-wideband signals in practical environments is given, including interference, coexistence and diversity considerations. The text includes antennas and propagation in biological media in addition to more conventional environments. The topics covered are approached with the aim of helping practising engineers to view the subject from a different angle, and to consider items as variables that were treated as constants in narrowband and wideband systems. Features tables of propagation data, photographs of antenna systems and graphs of results (e.g. radiation patterns, propagation characteristics) Covers the fundamentals of antennas and propagation, as well as offering an in-depth treatment of antenna elements and arrays for UWB systems, and UWB propagation models Provides a description of the underlying concepts for the design of antennas and arrays for conventional as well as ultra-wideband systems Draws together UWB theory by using case-studies to show applications of antennas and propagation in communication, radar and imaging systems The book highlights the unique design issues of using ultra-wideband and will serve both as an introductory text and a reference guide for designers and students alike.
