The constituent radiators that build a reflectarray can be shaped to bring about some flexibility in the way that antenna operates such as multi band/polarization operation. The printed nature of these elements allow integration of active elements that can further enhance the functionality of the reflectarray. This allows for capabilities such as power amplification, adaptive beam shaping, and beam switching. This resource presents readers with design guidelines along with an ample amount of material on different types of reflectarrays and methods of analysis. This book begins with introductory material on reflectarray antennas and progresses to the presentation of state-of-the-art research in the field. A direct comparison with conventional reflector antennas is provided, focusing on conventional efficiency figures of reflectors. Moreover, this book offers remarks on the future direction of reflectarray research and also potential applications of the technology in face of the emergence of new fabrication techniques to accommodate both passive and active elements.Artech House antennas and propagation library.Antennas, ReflectarrayAntennas, Reflectarray.621.3824Shaker Jafar1717749Chaharmir Mohammad Reza1717750Ethier Jonathan1717751CaBNVSLCaBNVSLCaBNVSLBOOK9910808291103321Reflectarray Antennas4114254UNINA
