Microwave Filters, Antennas and Filtennas For 5G summaries the design, simulation, fabrication and measurement of efficient and compact RF filters, antennas and filtering antennas (filtennas) for 5G transceivers. Where possible pictures of real devices have been used to illustrate the theory. Drawing from the editors vast experience in linear and nonlinear RF applications and of being at the forefront of 5G systems, this book also aims to discuss and review the recent developments and challenges in the design techniques of reconfigurable filters and antennas, as well as their integration. It is expected that the book will be useful to MSc and PhD students and will hopefully serve as a valuable tool for all RF/Microwave researchers, in academia and industry alike, to draw inspiration towards taking further innovative strides in this fast‐evolving arena. It should also provide a useful reference for RF research workers and engineers who are designing and/or specifying filters and antennas for commercial systems.
