Antenna Theory

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.
