Introduction – Examples of antenna systems, radiation patterns, directivity, polarization, antenna impedance, effective area, Friis’ equation, the radar equation, antenna temperature and noise.
Antenna radiation – the antenna as a source of radiation, duality and reciprocity, near- and far-field form a dipole, image theory, mutual coupling. Aperture antennas and Babinet’s principle, microstrip antennas. Linear and planar antenna arrays, synthesis of radiation patterns.
Physical limits – Super directivity, bandwidth vs. size, mutual resistance and correlation.
Practical design – High gain, conformal, low frequency, and terminal antennas.
System aspects – Radar, radar cross-section of antennas, radio propagation, link budget, fading space and polarization diversity. Cellular and sector systems, adaptive and multi-beam antennas.
