Under his leadership, the company grew and prospered. With design expe-
rience from simple Yagi-Uda arrays to exotic multiple-feed systems, Jasik
Laboratories became widely known throughout the electronics industry as
an unusually talented team of antenna specialists. They designed, manu-
factured, and tested a wide variety of antennas, such as dipoles, horns, log
periodics, double-conical feeds, and many others. In 1969, Cutler-Hammer
(which later became the Eaton Corporation) acquired Jasik Laboratories,

Preface
THIRD EDITION
It has been more than three decades since Henry Jasik envisioned and edited the First
Edition of the Antenna Engineering Handbook. During this time, many significant and
far-reaching advances have been made in the field of antenna technology.
The Second Edition was published more than two decades after the First Edition,
and it required many major revisions and additions. For example, it contained 15 new
chapters to cover new subject areas.
Work on this Third Edition of the Handbook began 10 years after starting work on
the Second Edition. Ten years is a long time given today's rapid advancementsi n antenna
technology, so an update is welcome and beneficial.
This new edition again contains four major parts:
Introduction and Fundamentals Part 1 presents basic comments, defines parame-
ters, and discusses fundamentals that are common to most antennas.
Types and Design Methods Part 2 presents the primary antenna types and design
methods that currently are in use. Emphasis is on succinct descriptions, design data, and
references.
Applications Part 3 discusses major applications of antennas. Emphasis is on how
antennas are employed to meet electronic system requirements. Design methods which
are unique to the applications are presented.
Topics Associated with Antennas Part 4 deals with topics that are closely related to
antenna design. The topics are covered succinctly,b ut more detailed information can be
found in the references.
Thanks are extended to the many publishers who have granted permission to use
material from their publications. As was done in the previous editions, we have tried to
credit all sources of information by references; any omissions are due to oversight rather
than intent.
The work of many outstanding engineers who reviewed and updated the individual
chapters has made this Third Edition of the Handbook possible. Their magnificent efforts
enabled this project to be completed according to the initial schedule.
It is impossible to acknowledge all the other individuals who have made contribu-
tions to this book, so I thank them all as agroup. Again, I extend special thanks to Maurice
Antenna
W. Long and J. Searcy Hollis, who introduced me to the fascinating world of antennas.
Their keen insight and guidance helped me, in many cases, to "see" the electrical currents
flowing on an antenna. Engineering
Finally, I want to acknowledge the lasting contributions of Henry Jasik, who con-
ceived and edited the First Edition of this Handbook. When I took the assignment to edit Handbook
the Second Edition, I considered several alternate ways to organize the subject matter;
however, in the end, I concluded that Henry's outline was better than all the others. This
Handbook is dedicated to the memory of Henry Jasik. His influence is clearly present in
this Third Edition, and it probably will continue through future editions.
