This practical resource covers the basics of electromagnetics, wave propagation, and antennas for radiated RF projects. General, high-level scenarios of one-way, two-antenna RF transmission-reception also known as the Friis Equation systems are illustrated. Characteristics of electromagnetic waves, free space loss, multipath loss, and Fresnel zone loss are presented. Antenna groupings, including isotropic point source, wire, aperture, and slot and array are explained. Antenna measurements are also presented, including squared wavelengths, 2, this electrical sizing resulting in low, medium, and high directivity gain antennas.
