ET4015 Antenna systems
Topics: Antenna theory and techniques for applications in telecommunications, remote sensing and radarThe aim of this course is to introduce the students to the antenna techniques that are instrumental for applications such as telecommunications, remote sensing and radar systems. After introducing basic antenna concepts such as the fundamental radiation mechanisms, the basic antenna parameters are defined. A detailed description of the antenna gain, directivity, polarization, radiation pattern, bandwidth, beamwidth, efficiency, temperature, effective length, effective area and input impedance is given. The radiation from an infinitesimal dipole is detailed. The integral equation formulation of the radiation from wire type antennas is introduced. The radiation from linear, circular and planar array antennas is discussed in detail while stressing their importance in radar and remote sensing systems. Design techniques for array antennas are described. Aperture antennas are introduced and discussed with particular emphasis on open-ended waveguide and horn antennas. Microstrip radiators, reflector and broadband antennas are also introduced. Some basic concepts about antenna measurements techniques are introduced.
The lectures are complemented with classroom exercises and antenna measurements performed at the facilities available at TU Delft.
