This paper is a tutorial on the theory of antennas, and it has been written as an introduction for the nonspecialist and as a review for the expert. The paper traces the history of antennas and some of the most basic radiating elements, demonstrates the fundamental principles of antenna radiation, reviews Maxwell’s equations and electromagnetic boundary conditions, and outlines basic procedures and equations of radiation. Modeling of antenna source excitation is illustrated, and antenna parameters and figures-of-merit are reviewed. Finally, theorems, arraying principles, and advanced asymptotic methods for antenna analysis and design are summarized.
