On completion of the course the student shall be able to
calculate the fundamental parameters for antennas and the radiation field from an antenna using potential functions,
describe the radiation from isolated, linear wire antennas and from linear elements near or on a conducting surface,
account for circular loop antennas and apply the field equivalence principle to aperture antennas,
account for the most important properties of travelling wave antennas, broadband antennas and microstrip antennas and how to match an antenna to a transmission line,
account for the principles of antenna arrays, and use antenna synthesis in order to design arrays,
account for the basic methods for antenna measurements.
