Antenna and Wave Propagation is to introduce to the students the basics of radiating elements and effect of propagation of radio waves in actual environment. This course provides students with comprehensive coverage of a wide variety of antennas and propagation topics related to numerous communication systems with a particular emphasis on military applications. The course presents fundamental theory together with techniques for the practical design, measurement and application of antennas over the RF (radio-frequency) to millimetre wave frequency range.
