This website is intended to be a source of knowledge for learning about and
understanding antennas. The goal is to present a comprehensive tutorial on
antennas. In the spirit of Einstein:



"Everything should be made as simple as possible, but not simpler."



This website will strive to make antennas understandable, without unnecessary
complexity.

About this Site:

Antennas and Antenna Theory has always been a fascinating subject for me, and it
is this excitement that leads me to present this tutorial. In my life, I have
found that once I thoroughly understand a subject, I am amazed at how simple it
seems, despite the initial complexity. This I have found true for a wide range
of activities, be it riding a motorcycle, learning about antennas, or
understanding physical phenomena such as electromagnetics. With that in mind, I
endeavor to write this Antenna Theory website in the simplest of all possible
manners.

Specifically, consider this statement: Complexity is not a sign of intelligence;
simplify. I have found this to a priceless amount of wisdom. In that regard, one
need not know the intricacies of Lebesgue integration or complex integrals
involving Cauchy residues in order to fully understand Antenna Theory. In fact,
most people who focus on the mathematical intricacies of Maxwell's Equations
tend to be poor practicing antenna engineers (probably because they try to write
code or derive integrals instead of put a product together). The subject of
Antennas is best understood intuitively; this is in stark contrast to the
methods in University, where complex math pervades every page. I do not think
this approach effectively teaches antenna theory. In these pages you will not
find rigorous mathematical analysis which only apply in the simplest of antenna
cases (and are ultimately artificial for the real world); I will try to state
facts and a minimum of math except where necessary. I also try to avoid making
things unnecessarily complicated. For instance, VSWR stands for Voltage Standing
Wave Ratio, and sounds very complicated. But it is simply a measure of how much
power is reflected from an antenna. Avoiding unnecessary complexity is a
lifelong goal of mine.

About me:

I am a practicing antenna engineer, with a PhD in antennas and I have worked for
many years in defense, university and the consumer electronics field as an
antenna engineer. My dissertation in pdf form is available here: Antenna Arrays:
Performance Limits and Geometry Optimization.
