The Poynting Vector Antenna  by Ted Hart and Paul Birke

Two Engineers, *Ted Hart* from Georgia in the USA and *Paul Birke* from
Ontario, Canada have teamed up to write this book. With over 100 years of
combined antenna and electrical engineering experience, they have applied
the Poynting Vector Theorem of 1884 to fabricate a new antenna technology.

The result is the Poynting Vector Antenna that has a much smaller
footprint, only a small fraction of the size of an equivalent Hertz
Antenna. The wide frequency tuning range, high efficiency, and large
instantaneous bandwidth place this antenna in a unique category all alone.

The book gives theoretical explanations and practical examples which
underpin the engineering basis of this new and unique antenna, which is a
radical departure from the conventional Hertz antenna. The evolution of
this antenna concept is presented as well as simple examples that may be
readily copied, and finally what the Authors believe to be the ultimate
physical configuration in the shape of a Flute.

The theoretical explanation of Radiation Resistance (based on quantum
electrodynamics) and other new Physics concepts are presented, including
suggested changes to Maxwell’s equations.

Radio Amateurs can enjoy versions of this antenna as well as the Military
and other communication services from AM Broadcast frequencies through VHF.

*“I now feel that the most consistent application of the Maxwellian spirit
is to define “radiation� to be the flow of energy described by the Poynting
Vector.� *

*HIGHLIGHTS OF WHAT IS IN THE BOOK: The first five chapters provide both
technical and historical background. Then, Chapter 6 details the antenna
suggested for Hams to copy. The detailed example is for 40 meters. It
includes three alternate feed networks and associated performance
parameters to allow the reader a choice. This 40 meter design can be scaled
for any Ham band from 160 thru 2 meters. There is a 160 meter antenna
design detailed also in Chapter 6. For alternative designs the full range
(6 – 160 meters) of Flat Antennas (Guillotine) are detailed in Chapter 15.
Another alternative design is given in Chapter 16. Chapter 17 covers a new
concept antenna developed while writing the book. Chapter 18 details the
Flute TM design, the ultimate performance antenna. This antenna could be
difficult for Hams to copy for the relatively small performance enhancement
over the Chapter 6 design. The major enhancement is bandwidth. *

*The book does go into great detail to fully explain the theory behind the
antenna as well as the outstanding performance parameters. Comparison to a
conventional Hertz antenna illustrates why this antenna is the antenna of
choice except for directional beam antennas. The book and the subject of
Poynting Vector antennas would not be complete without the detailed theory.
Any Ham can build and use one of the antennas; alternatively, the book
provides information not previously available to the professional antenna
designers. This includes the first ever theoretical explanation of how
Radiation Resistance is developed in an antenna. It also blows away the
long held concept that small antennas cannot be effective. Specifically the
Chu-Wheeler concept is no longer valid. While doing research for the book
Paul (the co-author) realized that Maxwell’s Equations need revision to
cover all cases, a change that has been need by the Physics community for
more than 100 years. *

*Conny Winrot SM6DCO remarks that Ted and Paul tried to cover all the
bases. For that reason it took them four years of dedicated effort to
develop the book.*
