Array and Phased Array Antenna Basics
Chapter One
Radiation
The key to understanding phased array antennas is to understand antennas and the key to
understanding antennas is to understand electromagnetic radiation. In contrast to what is
widely believed, one does not need to be a specialist in integro-differential equations and
vector mathematics to grasp the mechanism of electromagnetic radiation. As in Faraday's
time, a vast majority of educators prefers the rigor of a mathematical description to the
insight of a physical understanding for explaining the mechanism of radiation. It is the
author's belief though that the latter is needed first to form the basic understanding and
once this understanding has been accomplished, the former may be used to develop this
understanding and put it to practical use.
For the basic understanding of electromagnetic radiation one only needs an
understanding of electricity and magnetism at a level as educated in secondary school.
