field, and calculating received power.6 Dipole and monopole antennasare studied next, followed by a brief look at a variety of other antennas and antennas systems:helix, biconical, spiral, horn, loop, dish, antenna arrays, and radomes.1The next topic is RF propagation. The concept of an EM wave is expanded to include awavefront, plane wave, power density, electric field strength, permeability, and permittivity.6Then wave propagation in “other than free” space is covered: reflection, refraction, and Page 24.176.4diffraction.6 This is followed by ground waves, space waves, tropospheric scatter, and skywaves; 6 and finally, free space propagation
