Advanced Antenna Theory

Basic antenna parameters. Transmission loss, radar equation. Retarded potentials, thin linear wire antennas. Hertzian dipole, small dipole, finite length and half-wavelength dipoles. Vector potentials, field equivalence principle. Rectangular and circular apertures. Horns. Induced current, parabolic reflectors. Array antennas, uniform and non-uniform aperture distributions, scanning arrays, pattern synthesis, planar arrays.
