We have seen that Maxwell's equations predict that electromagnetic waves are possible. We would like to understand how electromagnetic waves are created. We will explore a basic model of an antenna. However, in practice, antennas not usually connected to radios directly, but instead are connected with a cable called a transmission line or feed line. We will explore a simple model for how a transmission line can transfer electromagnetic energy through it from one end to the other.
