This white paper is intended as a guide to understanding how antennas transmit and receive electromagnetic waves. An explanation of what electromagnetic waves are, and how they travel will be discussed. Then, by studying a half wave dipole antenna, we will learn how an antenna radiates electric and magnetic fields. We will discover how these radiated electric and magnetic fields travel together as electromagnetic waves. Finally, polarization will be defined, and its importance in antenna design will be explained.
The following scenarios will be discussed:
Electric Fields, Magnetic Fields, and Electromagnetic Radiation
