Course objectiveIt is aimed to give the following topics to the students; Fundametals of radiation theory, Antenna parameters, Radiation from wire antennas (current elements) Radiation from Aperture antennas and equivalence theorem, Antenna arrays, Receiving antennas, reciprocity theorem, noise, radar range equation, Propagation mechanisms of electromagnetic waves from ELF band to EHF band, Parameters of signal propagation to form a solid foundation in radiation and propagation of electromagnetic waves, so that the students can apply the principles of radiation and propagation to the problems which they may encounter within their studies/thesis/projects.  
Learning outcomes
  1. Form the radiation integral for given antenna geometry, boundary conditions, and frequency range,
  2. Obtain the radiated electromagnetic wave in Fraunhofer region, Conservation theorems of electromagnetic wave theory to obtain radiated electromagnetic field from various antenna structures,
  3. Apply Symmetry and Duality, Uniqueness, Reciprocity, Equivalence and Power
  4. Understand the parameters of wave propagation and identify the constraints due to environment, geometry, frequency, polarization, and medium of propagation,
  5. Have the solid foundations to solve real life problems in electromagnetic wave radiation from various types of antennas and propagation in a source-free medium.
Course ContentFundamentals of radiation theory,
Antenna parameters,
Radiation from elementary dipoles and loops,
Radiation integrals for current (wire) antennas,
