Fundamentals of Antenna Theory
Or perhaps you have never heard of (or are a little rusty) on the above parameters.
Well then, you've come to the right place. Before we can design an antenna or discuss antenna types, we
must understand the above antenna properties, which are the fundamental parameters
that characterize an antenna.
So let us learn something. We'll start with frequency and step through the rest of
the parameters. Jump ahead if this is already familiar to you.
More Advanced Frequency Information
Lets get right down to it. Suppose one day you're walking down the
street and a kind but impatient person runs up and asks you to design an antenna
for them. "Sure", you quickly reply, adding "what is the desired frequency, gain,
bandwidth, impedance, and polarization?"
