The aim of the course is to provide an overview of standard and wireless communication systems. The theory of electromagnetic waves is presented as a means to the understanding of the electromagnetic behavior of practical communication systems. Additionally, the basic characteristics of antennas are explained and various antenna architectures are analyzed.


  • Time-varying fields: Maxwell's equations in vacuum and in matter, electromagnetic (EM) wave equation, energy in EM waves, the Pointing vector.
  • Plane EM waves:Definition of Plane wave, polarization, phase and group velocity.
  • Reflection and refraction of plane EM waves:Snell law, Fresnel equations, amplitude reflection and transmission coefficients, total internal reflection-Fibre optics, Brewster angle- polarizers, standing waves
  • Waveguides:Geometrical optics, TE, TM and TEM modes, slab and cylindrical dielectric waveguides, power and loss.
  • Transmission lines:Circuit theory and field theory, basic field cell, uniform transmission line of two conductors with infinite length, Z0, uniform transmission line terminated on a load, Smith diagram.
  • Basic antenna characteristics:Fresnel and Fraunhofer field, current distribution, radiation power, Radiation resistor, loss resistor, performance, Input resistor, radiation diagram, Half power beam width, Directionality, Friis equation.
  • Basic antenna types:Basic dipole, antenna bronchus, antenna ë/2, helical antenna, influence of the ground on the performance of horizontal and vertical antennas, antenna Marconi
  • Sets of antennas:Sets of isotropic sources, antenna Yagi-Uda, Propagation of E/M waves in the terrestrial environment, ground waves, ionosphere waves, Frequency bands: characteristics and applications.



Open source software will be used for the laboratory exercises. They will cover:

  • Operation of the program NEC4WIN95VM
  • Radiation from an infinitesimal dipole.
  • λ/2 dipole antenna
  • Resonance Phenomena.
  • Vertical antennas
  • Special cases of linear antennas
  • Antenna Arrays
  • Loop antennas
  • Helix antennas
  • Yagi-Uda antennas
