Introduction to Reflectarray Antennas

This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book provides scientists and engineers in the fields of antenna, microwave, and electromagnetic, with an up‐to‐date knowledge of reflectarray antenna theories as well as the design and analysis techniques. It presents a brief description on the reflectarray antenna research history, including various implementations and state‐of‐the‐art. The book is intended for engineers that know the basics of antenna theory and are starting to become familiar with this new generation of high‐gain antennas. It is also intended for researchers and specialists that have a good knowledge of the basic theories in reflectarray, and aim at designing reflectarray antennas for specific applications/operations. The book explores the basic theories for analysis and design of reflectarray antennas. It provides design examples, where a variety of reflectarray designs are presented that can serve as a useful reference for interested readers.
