It provides the theory beckground for using wave propagation in communication. The course consists of five lessons. Lesson I Basic Electrici has an introduction to electricity, and covers the composition of matter, conductors and insulators, basic laws, electric current, electromotive force, resistance, magnets, the nature of magnetism, and elec .ric symbols. Lessan 2 Antenna and Transmission Line Fundamentals discusses the electromagnetic field, antenna theory, radiation, graphs, polarization, antenna input impedance, transmission line theory and the types of transmission line. Lesson 3 QuarterWave, half-Wave Antennas and Associated Radiation Patterns contains two sections. Section I describes whip (Marconi), ground plane, bent, folded-top, top-loaded, and tower radiated antennas. Section II discusses Her% ground affected radiation patterns, single wire antennas, folded dipole, coaxial, conical and microwave antennas, and multielement arrays. Lesson 4 Long-Wire Antennas and Antenna installation contains two sections. Section
