Written to bridge the gap between basic theory and graduate-level engineering texts, the second edition of Antenna Physics: An Introduction includes new material to help you better understand the complexities of antenna theory.
World-recognized antenna technology authority Robert J. Zavrel, Jr., W7SX, is your guide to grasping a deeper understanding of how antenna systems function. In this book, he clearly communicates the theory and the mathematics that form the foundations upon which all antenna designs depend.
