Antennas and Electromagnetic Radiation
After discussing wave propagation, it is time we go back and discuss the sources of the waves. Recall that our whole discussion of waves was based on the solution to the source-free wave equation. Starting with Chapter 11, we assumed that a wave was generated in some fashion but did not concern ourselves too much with how the wave was generated. Occasionally, the term “source” or “antenna” was mentioned but only to indicate that the wave must have a source.
