| Summary: | The scope of this book is a class of antennas termed electronic scanned arrays (ESAs). The discussion focuses on antenna hardware, specifically radar antennas, although communications and receive antennas are broadly similar. The book has 18 chapters and is divided into 4 parts. The first deals with design principles, approaches, architectures and partitioning of apertures antennas applied to the specific case of ESA design. System applications,such as communications and radar, will be discussed to set the framework for requirements allocation. The second part deals with common ESA design issues, numerical examples illustrate performance of design choices. ESA and reflector antennas with ESA feeds for reflectors are described. The third part deals with practical design considerations, looking into the choice of specific components, radiating elements, T/R modules, monolithic microwave integrated circuits (MMICs), and microwave distribution and packaging. The final part deals with space systems and ESA design example. Appendices on further reading, MATLAB code and the geometry of the system are given.
