This is a senior undergraduate or first-year graduate level textbook on antenna fundamentals@ design@ performance analysis@ and measurements. In addition to its use as a formal course textbook@ it is well-suited for professional training and self-study by practicing engineers@ scientists@ and technologists who desire to expand their knowledge of antennas. The book provides a broad coverage of antenna types and phenomena@ for operations at very low radio frequencies@ as well as frequencies up to those of submillimeter wavelengths. Unlike most university-level antenna textbooks@ it does not require prior skills in electromagnetic theory@ sophisticated mathematics@ or computer programming. An additional feature is the downloadable collection of computer solutions in both Mathcad?? and MATLAB?? to numerous antenna radiation examples@ which can be easily implemented and revised by persons not having prior programming experience.
