Overview

Part 2

Then we give more details of the Chapter 1, this is what you get here for free. We explain RF and microwave, describe what electromagnetic spectrum means and name the different frequency bands that are in use.

Electromagnetic frequency spectrum

Part 5

We look into the details of the electromagnetic spectrum and why the size of an antenna matters.
