The material in this book provides seven individual research studies on the optimization of array structures from different aspects. Referring to the contents of the book, the studies have been classified in two main parts: "array optimization," which covers the pattern-based approaches in electromagnetic and communications, and "elements and feed network," which covers the element and feed network design. I would like to congratulate all the authors for their valuable contributions and to thank IntechOpen, who made this book project possible. I hope this book will contribute to the scientific community dealing with the optimization of array structures.
