Microwave Resonators and Filters for Wireless Communication

Beschreibung

This book describes the basic theory of microwave resonators and filters, and practical design methods for wireless communication equipment. Wireless communication is rapidly gaining in importance in our modern information society. Mobile communication equipment is required to be more compact, lighter weight, to have longer operating times, and be battery operated for portability. The microwave resonators and filters described in this book provide a basis for realizing all these requirements. From the basic theory to applications, the text enables the reader to understand the key role played by microwave resonators and filters. Superconducting devices and micro-electromechanical devices are also described. The sections on design theory will be especially informative for microwave researchers and engineers.
Anytime. Anywhere. Mobile communication lets you keep in touch. The introduction of radio wave transmission by G. M. Marconi and the tele phone by Graham Bell in the late 19th century together brought dramatic changes in the way we communicate. By combining the two, we now possess a powerful communication tool enabling us to keep in touch with anyone, any time and anywhere. Technological breakthroughs have contributed to this scheme by providing compact electronic devices, and without such progress, our present situation could not have existed. We foresee a bright future based on the further progress of mobile communication. The authors of this book have engaged in the downsizing of radio frequency (RF) circuits found in wireless communication devices. Filtering devices are an essential component for such circuits, and considerable effort has been put into the research and development of such devices. This book starts from a conceptual view of such filters, and expands on this idea to provide a practical solution for the application of filtering devices. The purpose of this book is (1) to provide general information and ba sic design procedures for filters applied to wireless communication systems, (2) to illustrate the availability and introduce actual design examples of the stepped-impedance resonator (SIR) structure intended for the RF /microwave region, and (3) to propose a more general concept for transmission-line res onators based on an expanded SIR structure.
