### Description

Selected topics from recent engineering literature on antennas; current techniques for analysis of wire, slot, horn, frequency-independent, quasi-optical, and array antennas.

### Topics

• Antenna system parameters: gain; directivity; efficiency; impedance; antenna temperature
• Methods of antenna analysis: equivalence theorem; induction theorem; Huygens' principle; Kirchoff approximation; Fourier transform; physical and geometrical optics; scattering of electromagnetic waves; method of moments
• Integral equations for simple radiators: thin wire antennas and linear dipoles; kernel functions and approximate representations, numerical solution
• Antenna noise temperature: Nyquist theorem; computation of antenna temperature
• Discrete arrays and aperture antennas: general introduction; synthesis; optimization of directive gain and signal-to noise ratio; super-gain phenomena; sensitivity and stability analysis; large phased arrays; mismatch and blind angle phenomena; aperiodic arrays
• Special topics: log-periodic antennas; low-profile antennas; multiple-beam and steerable-beam antennas; reflector antennas; artificial lens and boot-lace antennas; aberrations and method of corrections; corrugated waveguides and horns
