This book offers a synthetic presentation of the fascinating subject of microwave engineering technology, intended for a university master’s degree course. The topics are: a quick review of guided wave propagation, matrix description of circuits, microwave passive devices, resonators and finally microwave filters, a subject that covers about half of the book. The final goal is to smoothly drive the reader towards an educated design of the devices discussed in the book. Because of the rather practical and synthetic approach, we assume some background on electromagnetic waves and distributed circuits.
Gian Guido Gentili
graduated from Politecnico di Milano and in 1989 he joined the CNR (National Research Council), first as a junior researcher, then as a senior researcher. Since 2002 he is an associate professor at Politecnico di Milano. His main research interests are microwave passive devices, antennas and computational electromagnetics. He is a member of IEEE and has published about 150 papers in international journals and international and national conferences. He contributed to the Encyclopedia of RF and Microwave Engineering with two chapters, one on horn antennas and another on Ortho-ModeTransducers. He published several educational books and exercise books on electromagnetics.
Matteo Oldoni
received his Ph.D. degree in Information Technology from the Politecnico di Milano, Milan, Italy, in 2013. Mr. Oldoni was the recipient of the Young Engineers Prize of the 39th European Microwave Conference. He has worked as Microwave Designer in the Passive Microwave Components Laboratory of a private company, becoming a Member of the Technical Staff, and cooperated with several companies and research institutions internationally. From June 2022 he is a full-time researcher at the Electronics, Information and Bioengineering Dept. of Politecnico di Milano. His research interests include synthesis and design techniques for microwave filters, algorithm development for computer-aided tuning, and antenna design. He is an Associate Editor of IEEE Microwave and Wireless Technology Letters since 2023.
