Communication Systems

Microwave frequencies and uses; microwave transmission in transmission lines and waveguides, microwave circuits: impedance transformation and matching. Passive microwave devices, resonant and filter circuits. Active microwave devices: Klystron and magnetron tubes and semi-conductor devices for microwave generation.

Antennas: Antenna theory; definition of antenna parameters; practical antennas – dipole antenna, antenna arrays and parabolic antennas. Antenna design issues.

Electromagnetic wave propagation: propagation in the ionosphere, troposphere and in stratified media; principles of scatter propagation; applications in general broadcast: television and radio.
