Book 31

This is the only book currently available that covers this subject. The authors piece together information from diverse areas which is essential to understand integrated and integrated active antennas. Emphasis is placed on active antennas and power combining applications, consolidating the work from numerous researchers. Early chapters lay the foundation for oscillator, antenna, array and power combining theory. Chapter five discusses important testing parameters and techniques for active antenna measurements and includes definitions for equivalent isotropic radiated power, locking gain and locking bandwidth. The last chapter sheds light on beam steering, a more recent development in active antenna arrays. Contains over 200 illustrations.

Book 63

This is the first book to provide comprehensive coverage of hardware and circuit design specifically for engineers working in wireless communications. It serves as a reference for practicing engineers and technicians working in the areas of RF, microwaves, communications, solid-state devices, and radar.

Book 65

A comprehensive introduction to the hardware, parameters, and architectures of RF/microwave wireless systems As the basis for some of the hottest technologies of the new millennium, radio frequency (RF) and microwave wireless systems rapidly propel us toward a future in which the transmission of voice, video, and data communications will be possible anywhere in the world through the use of simple, handheld devices. This book provides scientists and engineers with clear, thorough, up-to-date explanations of all aspects of RF and microwave wireless systems, including general hardware components, system parameters, and architectures. Renowned authority Kai Chang covers both communication and radar/sensor systems and extends the discussion to other intriguing topics, from global positioning systems (GPS) to smart highways and smart automobiles. With an emphasis on basic operating principles, Dr. Chang reviews waves and transmission lines, examines modulation and demodulation and multiple-access techniques, and helps bridge the gap between RF/microwave engineering and communication system design.
Ample practical examples of components and system configurations and nearly 300 illustrations and photographs complete this timely and indispensable resource. An Instructor's Manual presenting detailed solutions to all the problems in the book is available from the Wiley editorial department

This book discusses microwave ring circuits--specialized circuits or wavelengths with applications in various microwave devices. Although microwave ring circuits have many important applications in antennas, filters, oscillators, etc., they are often ignored in most books because of their specialized nature.

The comprehensive reference text focuses on the basic operating principles and the techniques used to incorporate solid-state devices into circuit applications. Fundamental design equations are derived and practical examples are given whenever possible.

This second edition has been updated with the addition of the latest materials of new developments and various transistor (MESFET, HBT, and HEMT) circuits and applications. Existing chapters have been expanded to include such topics as microstrip resonators, couplers, and filters; and transmitter and oscillator system parameters. Another chapter will be updated with information on testing methods and equipment, including probing and fixturing methods, a review of testing and calibration methods, and a review of automated test equipment. Interactive software will also be included, and there is a 50% increase in problems and examples.

The definitive text on microwave ring circuits, now better than ever. For the past three decades, the ring resonator has been widely used in such applications as measurements, filters, oscillators, mixers, couplers, power dividers/combiners, antennas, and frequency-selective surfaces, to name just a few. The field has continued to expand, with many new analyses, models, and applications recently reported. "Microwave Ring Circuits and Related Structures" has long been the only text fully dedicated to the treatment of ring resonators. The second edition has been thoroughly revised to reflect the most current developments in the field. In addition to updating all the original material, the authors have added extensive new coverage on: A universal model for both rectangular and circular ring configurations; Applications of ring structures for all types of planar circuits; A new transmission line analysis; An abundance of new applications in bandpass and bandstop filters, couplers, oscillators, and antennas.
While retaining all the features that made the original text so useful to both students and teachers in the field, the second edition seeks to introduce the analysis and models of ring resonators and to apply them to both the old and the new applications, including microstrip, slotline, coplanar waveguide, and waveguide transmission lines. Based on dissertations and papers published by graduate students, scholars, and research associates at A&M University, "Microwave Ring Circuits and Related Structures, Second Edition" is sure to be a valuable addition to both engineering classrooms and research libraries in the field.
