Design and Realizations of Miniaturized Fractal Microwave and RF Filters

Pierre Jarry graduated from the University of Limoges. As a professor at University of Brest, he directed the Laboratory of Electronics and Telecommunication Systems (LEST), affiliated with the French National Center for Scientific Research (CNRS). He later joined the University of Bordeaux and the CNRS laboratory IMS. He has published 300 technical papers in microwave and RF circuit synthesis, and is a senior member of the IEEE.

Miniaturized filters are well suited for the increasing number of compact and low power applications. Presenting studies of the performance of fractal resonators and sensitivity analyses of suspended substrate realizations, Design and Realizations of Miniaturized Fractal Microwave and RF Filters provides RF and microwave engineers and researchers, advanced graduate students, and wireless and telecommunication engineers with the knowledge and skills to design and realize miniaturized fractal microwave and RF filters. This definitive source provides timely insight on fractal resonators for compact and low power microwave and RF.
