Описание: With design optimization as a key focus, this book covers both antenna fundamentals and microstrip antenna. It includes a section on antenna theory that introduces two kinds of elementary linear sources, Huygen’s planar element, and also the analysis and synthesis of the discrete and continuous arrays formed by these elementary sources. In addition, it introduces the digital beam-forming antenna and smart antenna. The section on microstrip antenna discusses the cavity mode theory and also covers some related issues including the design of irregularly shaped patches and the analysis of mutual coupling. With several effective design approaches covered, this book can serve as either a textbook or a self-study book.
Описание: In recent years, antenna technologies have received a renewed interest because of the rapid development of wireless devices and advanced defense applications. Consequently, highly accurate and efficient modeling and simulation tools are needed to satisfy the demand for sophisticated antenna designs. This book covers all the technical aspects in the analysis of complex antennas and arrays using the finite element method.

Описание: Cylindrical arrays lie at the heart of the antenna systems of most major radio communication systems, including broadcasting networks, cellular 'phone systems and radar. In this book, the authors present practical theoretical methods for determining current distributions, input admittances and field patterns of a wide variety of cylindrical antennas, including the isolated antenna, the two-element array, the circular array, curtain arrays, Yagi and log-periodic arrays, planar arrays and three-dimensional arrays. Coverage includes analysis of horizontal antennas over, on and in tharth and sea, large resonant arrays of electrically short dipoles and a chapter on the theory and techniques of experimental measurement. Written by three of the leading engineers in the field, and based on world-class research carried out at Harvard over the last 40 years, Cylindrical Antennas and Arrays is destined to become established as the basic reference for practising engineers and advanced students for many years to come.

Описание: Reflects the developments in engineering and design of antennas. This work gives you the expertise you need to solve various kinds of engineering problems that may arise in the design and application of different types of antenna`s.
Описание: A complete examination of traditional and new advanced antennas used in the automotive industry, this book provides information taken from designs published in technical and academic papers, patents, and pending patents. Highlighting the practical aspects of antenna design, the authors describe the entire design process, starting with the antenna simulation, prototype sample fabrication, and laboratory test measurements, and finishing with test measurements in the real environment. The book includes simulation examples of antenna parameters that significantly speed up the design process using software packages such as FEKO, NEC, IE3D, and Genesys.
Описание: "Wireless Communications over MIMO Channels: Applications to CDMA and Multiple Antenna Systems" covers both, state of the art channel coding concepts
and CDMA and multiple antenna systems, rarely found in other books on the subject. Furthermore, an information theoretical analysis of CDMA and SDMA systems illuminate ultimate
limits and demonstrates the high potential of these concepts. Besides spatial multiplexing, the use of multiple transmit antennas in order to increase the link reliability by diversity concepts
(space time coding) is described.
Another focus is the application of error control coding in mobile radio communications. Accompanying appendices include: basic
derivations, tables of frequently used channel models, chain rules for entropy and information, data processing theorem, basics of linear algebra, Householder reflection and Givens
rotation, and the LLL algorithm for lattice reduction.
Описание: This book provides, for the first time, a single complete reference on microphone arrays. Top researchers in this field contributed articles addressing their specific topics of study. The results cover the current state of the art in microphone array research, development, and technological application. Part I concerns the problem of enhancing the speech signal acquired by an array of microphones. Part II is devoted to the source localization problem. Part III details some specific applications of microphone array technology available today. Part IV presents expert summaries of current open problems in the field, as well as personal views of what the future of microphone array processing might hold. The individual chapters selected for the book were designed to be tutorial in nature with a specific emphasis on recent important results. They are of utility to a large audience, from the student or practising engineer just approaching the field to the experienced researcher.
Описание: Field-Programmable Gate Arrays (FPGAs) are revolutionizing digital signal processing as novel FPGA families are replacing ASICs and PDSPs for front-end digital signal processing algorithms. So the efficient implementation of these algorithms is critical and is the main goal of this book. It starts with an overview of today's FPGA technology, devices, and tools for designing state-of-the-art DSP systems. A case study in the first chapter is the basis for more than 40 design examples throughout. The following chapters deal with computer arithmetic concepts, theory and the implementation of FIR and IIR filters, multirate digital signal processing systems, DFT and FFT algorithms, advanced algorithms with high future potential, and adaptive filters. Each chapter contains exercises. The VERILOG source code and a glossary are given in the appendices, while the accompanying CD-ROM contains the examples in VHDL and Verilog code as well as the newest Altera "Quartus II web edition" software. This edition has a new chapter on microprocessors, new sections on special functions using MAC calls, intellectual property core design and arbitrary sampling rate converters, and over 100 new exercises.

Описание: A tendency in present day literature is to publish on antennas (especially for mobile communications) that have been designed by trial-and-error, employing a full-wave electromagnetic analysis software package. Since the physics underlying the operation of these antennas are not fully understood or not fully described, the employment of these antenna types for other frequencies or other dielectrics as reported is often not straightforward. This problem is more serious for the inexperienced antenna engineer. Fast accurate antenna models that accompany new antenna concepts will help in getting these antenna concepts implemented in applications. In this book, different antennas for wireless and communications applications are discussed, each one linked to a specific application, thus emphasising the practical use of the antennas and models and not restricting the antennas to single applications. Detailed information about the model development and the use of the developed models will be given. The inexperienced antenna engineer will be guided through the design process of several antennas, including Intravascular MR Antennas, Component Antennas, PCB Antennas, RFID Antennas etc.
