EL6723 Electromagnetic Radiation and Antennas

The electromagnetic fields radiated by current elements are derived from Maxwell’s equations. From these results, the fields radiated by many types of antennas are derived, including various types of dipoles, arrays, aperture, frequency independent, and traveling wave antennas. Concepts such as radiation resistance and pattern, directivity, gain, effective area, reciprocity are discussed.

Prerequisites: graduate status and EL 6713, or EL 3604 with grade B or better.
