Covers the history, practical implementation, design techniques, and future developments of reflectarray antennas
Reflectarray antennas were invented more than forty years ago, but broad commercial interest only began little more than a decade ago as an outgrowth of the development of low–profile printed reflectarray antennas. Although widely covered in journal and conference papers, the topic has never been treated comprehensively in a single volume. Now, written by two experts in the field, Reflectarray Antennas offers complete coverage of this important, timely subject.
Beginning with an introduction to reflectarray antennas and an extensive overview of its history, the book goes on to explore:
The configuration and principles of a reflectarray antenna, and its advantages over other antennas
Antenna analysis techniques
Illustrated with photographs, drawings, and tables, this groundbreaking book is an important addition to any electrical engineer′s library, as well as critical to graduate students focused on antenna engineering and electromagnetics with an interest in reflectarray antenna designs.
