Summary

This book is a practical introduction and guide to microwave network analysis and circuit design, focusing on the vector network analyser (VNA) technique and simulation models. Accompanying VNA software (created by the author) gives the user the opportunity to see how a VNA operates and can be used for microwave measurements, data anaylsis, manipulation and comparison. It also provides a simulator that can be used to design a number of microwave circuits, allowing users to build circuits and study the properties of components and devices. The book begins by setting out the basic theory of network analysis, and defining network parameters. The following chapter describes in detail the installation and functions of the VNA software, before moving on to present built-in device models, analysing the associated equations and their limitations. The final two chapters summarise circuit design and operation principles for impedence matching, transformation, resonators, power dividers, coupler, filters and amplifiers, also giving design examples for these circuits.

Author Biography

Zhipeng Wu is currently a Professor in the Microwave and Communications Group in the School of Electrical and Electronic Engineering at the University of Manchester. His research interests are in the field of antennas and propagation for wireless and mobile communications, tomographic systems and sensors, and microwave engineering, and he has taught many courses on these topics including Masters courses in microwave measurements and communication systems, and senior undergraduate courses in microwave components and systems and communication principles. He has been at the university since 1998, and was elevated, in 2005 to become a Senior Member of the IEEE and Fellow of the IEE. He has been invited to be a program committee member of a number of international conferences, and will the Chair of the Technical Program Committee for the International Workshop on Antenna Technology in 2007. He has co-authored the book Radiowave Propagation Over Ground (Kluwer, 1993) and the accompanying software to this book, and also the vector network analyser (VNA) software for the proposed book. Along with this, he has written a chapter in the Wiley Encyclopedia of RF and Microwave Engineering (Wiley, 2005), and the book Dielectric Resonator Antennas (Research Studies Press, 2003), and authored over 120 conference and journal publications.
