The discipline of antenna theory has experienced vast technological changes. In response, Constantine Balanis has updated his classic text, Antenna Theory, offering the most recent look at all the necessary topics. Like the previous editions, Antenna Theory, Third Edition is designed to meet the needs of electrical engineering and physics students at the senior undergraduate and beginning graduate levels, and those of practicing engineers as well. The text assumes that the readers have a knowledge of basic undergraduate electromagnetic theory, including Maxwell's equations and the wave equation, introductory physics, and differential and integral calculus. The Third Edition offers new material that includes: A chapter on smart antennas, which is presently a hot topic of current interest to antenna engineers in a number of application areas, especially wireless communication A fractal antenna section, which introduces a new class of antennas that has received a lot of interest and attention after the second edition was published New end-of-chapter tables that provide a summary of important equations in each of the respective chapters Additional new figures, photos, and tables to better illustrate concepts Additional end-of-the-chapter problems An important new feature is the multimedia material on the accompanying CD, which presents: PowerPoint view graphs of lecture notes End-of-the-chapter interactive questions for revie Animations and applets for most of the chapters based on Java Second-edition FORTRAN computer programs translated to MATLAB® Additional new computer programs based on MATLAB® with applications to topics in the various chapters
