Description
This comprehensive book serves as a one-stop resource for practical EW antenna system know-how. Supported with over 700 illustrations and nearly 1,700 equations, this authoritative reference offers you detailed explanations of all the important foundations and aspects of this technology. Moreover, you get an in-depth treatment of a wide range of antenna system applications. The book presents the key characteristics of each type of antenna, including dipoles, monopoles, loops, arrays, horns, and patches. This authoritative volume enables you to analyze and design broadband communication and radar EW antennas, interface antennas to receivers and power amplifiers with maximum efficiency, use multicouplers to connect multiple receivers to a single antenna, and apply the correct kind of antenna to EW problems.
