Before we can design an antenna or discuss antenna types, we must understand the basics of antennas, which are the fundamental parameters that characterize an antenna. So let us learn something. We'll start with frequency and step through radiation patterns, directivity and gain, and ultimately close with an explanation on why antennas radiate.

The first module explains the various fundamental concepts and basic terms related to antenna theory. Some of the major topics covered here include basic parameters of antenna theory, meaning of near and far fields, radio pattern, concept of beam and polarization, calculation of beam width, property of reciprocity, and Poynting vector. 2.
An intuitive tutorial of antennas and antenna theory. This website is designed to present a comprehensive overview of antennas, from design, to measurement and theory. Unnecessarily complicated math is avoided throughout.
