Microstrip Filters for RF/Microwave Applications


Jia-Sheng Hong and M.J. Lancaster
John Wiley & Sons Inc.
471 pages; $125
ISBN: 0-471-38877-7

This book offers a unique and comprehensive treatment of RF and microwave filters based on microstrip structures. Many novel and sophisticated filters using computer-aided design are discussed. The book is not only a valuable design resource but also a handy reference for students, researchers and engineers in microwave engineering.

"[This book] emphasizes computer analysis and synthesis and full-wave electromagnetic simulation."

Its outstanding features include discussions of many novel microstrip filter configurations with advanced filtering characteristics, new design techniques and methods for filter miniaturization. It emphasizes computer analysis and synthesis and full-wave electromagnetic simulation.

The technical content of the book starts with Chapter 2, which describes various network concepts and equations. Chapter 3 introduces basic concepts and theories for the design of general RF/microwave filters. Chapter 4 summarizes basic concepts and design equations for microstrip lines, coupled microstrip lines and discontinuities, as well as lumped and distributed components. In Chapter 5, conventional microstrip low pass and band-pass filters are discussed with instructive design examples. Chapter 6 discusses some typical microstrip high pass and band-stop filters. The remaining chapters of the book deal with more advanced topics, starting with Chapter 7, which introduces some advanced materials and technologies for RF/microwave filter applications. Chapter 8 presents a comprehensive treatment of subjects regarding coupled resonator circuits, which are of importance for the design of RF/microwave filters, in particular narrow-band, pass-band filters. Chapter 9 is concerned with computer-aided design (CAD). It discusses computer simulation and/or computer optimization. The design of some advanced filters are discussed in Chapter 10, including selective filters with a single pair of transmission zeros, cascaded quadruplet (CQ) filters, cascaded trisection (CT) filters, cross-coupled filters, linear phase filters and extracted-poles filters. Chapter 11 is intended to describe novel concepts, methodologies and designs for compact filters and filter miniaturization. The final chapter of the book, Chapter 12, presents a case study of high temperature superconducting (HTS) microstrip filters for cellular base station applications.

Engineering Applications of the Modulated Scatterer Technique

Jean-Charles Bolomey and Fred E. Gardiol
Artech House Inc.
255 pages; $87, £64
ISBN: 1-58053-147-4

Numerical modeling deals with virtual models, more or less accurate representations of the physical world. Measurements remain the only way to characterize performance and validate design. Only since the fifties, has the measurement of a microwave field distribution been made possible without seriously altering it, by the development of the modulated scatterer technique (MST). The MST described in this book provides a flexible and efficient tool to analyze rapidly and efficiently the operation of many electric systems, both for high and low power applications.

The book provides a basic introduction to and a general overview of the field of MST extending from the basic concepts to more sophisticated recent developments. It presents the information in a way that should make it easy to understand, so that all readers should become familiar with the material. Many facets of the technique are presented, including some basic theory, principles of design and implementations. The book shows how the technique has been used to design several types of measurement setups, in order to analyze field distributions in a variety of practical applications.

"Measurements remain the only way to characterize performance and validate design."

Chapter 1 presents briefly the general context in which MST was developed and describes the main reasons for its development. Chapters 2 and 3 then provide the fundamental notions of electromagnetic theory needed to understand how MST setups operate and to acquire some design principles. Theoretical electromagnetic considerations continue in Chapter 3, which outlines probe responses under several operating conditions. Chapters 4 and 5 are devoted to the implementation of mobile probe systems, and present the theoretical background and a selection of practical realizations. In a similar manner, Chapters 6 and 7 consider the applications of probe arrays for rapid measurements. Here, too, the two chapters are respectively devoted to the presentation of the theoretical background and then to the description of practical implementations.
