EEE6223   Antennas, Propagation and Satellite Systems   (15 credits)

Description

Review and application of electromagnetic theory for antenna analysis. Radiation pattern, gain, input impedance. Half wave, full wave dipole antennas, monopole antennas. Image theory. Antenna arrays. Polarization: linear, elliptical, axial ratio. Aperture theory: Fourier analysis, Huygens-Kirchhoff formula, rectangular and circular aperture, effective aperture. Microstrip antennas. Propagation in a plasma: critical frequency, refractive index. Ionospheric/tropospheric propagation of HF/VHF radio waves: MUF, ionosonde. Satellite communications systems. Earth stations - types and performance. Satellite transponders - amplifiers, redundancy, transmitters, frequency translation. Multiple access systems.
