Supervisor:
Department of Electromagnetic Field
Synopsis:

Student will get strong knowledge about theory of electromagnetic field radiation and basic principles of antenna design.

Methods of analysis are demonstrated on various types of antennas and their arrays.

Seminars are both theoretical (analytical and numerical calculation using MATLAB and EM simulators CST) and practical (measurement of antenna parameters).

Requirements:

Good knowledge of electromagnetic field theory (electrodynamics), vector analysis and calculus.

Max. two leaves, in case of measurement seminars student has to perform measurement with other group.

Worked reports on antenna measurements are required.

Syllabus of lectures:

1. Transmission lines used for feeding antennas, antenna as a circuit component, equations for radiation of waves

2. Radiation ofo elementary dipole and loop, zones of radiation, directivity, polarization, antenna parameters.

3. Linear (wire) antennas, current distribution, calculation of impedance and radiation, folded dipole.

4. Antenna symmetrization, monopole antennas, antennas for radio transmission, trawelling-wave antennas.

5. Antenna arrays, broadside and endfire antennas, effect of amplitude and phase, radiation pattern of arrays.

6. Reciprocity and Babinet principle, slot antennas and their arrays, microstrip and wideband antennas.

7. Radiation from apertures, equivalent sources, Huygens source, directivity of aperture antennas.

8. Horn antennas, distribution of amplitude and phase of fields in aperture, polarization properties.

9. Reflector antennas, systems off-set, Cassegrain and Gregorian, effective apperture, calculation of radiation.

10. Feeds for reflector antennas, design for low-noise systems, realization of Huygens source.

11. Lenses and radomes, Maxwell, Fresnel, Luneburg and Rotman lens, zoning.
