We are pleased to present, in serial form, Chapters 3 and 4 of Antennas: Fundamentals, Design, Measurement (Third Edition), published by SciTech Publishing, Copyright 2009 (524 pages,
ISBN 9781891121784, all rights reserved by the publisher).
This new edition was prepared for a first year graduate course at Southern Polytechnic State University in Georgia. It provides broad coverage of antenna types and phenomena, for operations at very low radio frequencies, as well as frequencies up to those of submillimeter wavelengths.
This book is in contrast to most antenna textbooks, which are written for readers who are proficient with vector calculus and begin with the use of Maxwell's equations in the development of antenna theory. These books do not meet the needs of many students and engineers who, because of their backgrounds or personal interests, desire a more direct path for assimilating antenna fundamentals and their connection to application topics of antenna engineering.
You can see more about the book (which is also available with Mathcad 14.0 full feature program CD) here, and the detailed Table of Contents is here.

About the Author
Maurice Long, Ph.D. is currently a private radar consultant and adjunct faculty at Southern Polytechnic State University, Marietta, GA. While at Georgia Institute of Technology, he managed the development of a number of radar systems and held positions of principal research engineer, professor of electrical engineering, and Director of the Engineering Experiment Station, now known as Georgia Tech Research Institute (GTRI). Dr Long is the author of Radar Reflectivity of Land and Sea, 3rd Edition (Artech House) and Airborne Early Warning System Concepts (SciTech Publishing). This Third Edition builds on the previous editions by Lamont V. Blake (now deceased).
