This is the first book to focus specifically on antenna RCS reduction theory and design approaches. It covers both principles and engineering practice, and provides an in-depth study of a number of important topics, including fundamental theory, antenna and array analysis models, the rapid numerical computation method, and various low-RCS antenna design methods. The comprehensive and systematic discussion of practical issues in antenna RCS reduction makes it an ideal resource for readers interested in practical solutions to antenna stealth, particularly researchers, engineers and graduate students in the fields of microwave engineering, electrical and electronic engineering, and telecommunications engineering.
