Entry requirements
Electromagnetic field theory. The course is a useful complement to the courses Microwave engineering I and II, but can be taken independently of these.
Learning outcomes
On completion of the course the student shall be able to:
- calculate the fundamental parameters for antennas and account for Friis' transmission equation and the radar range equation
- use radiation integrals and potential functions in order to calculate the radiation fields from an antenna and account for the duality theorem, the reciprocity theorem and the reaction theorems
- describe different types of straight wire antennas, and derive the fields from an infinitesimal dipole
- account for self- and mutual impedance between straight antenna elements, and determine the radiation fields from straight elements near or on a conducting plane
- account for circular loop antennas, travelling wave antennas, broadband antennas and microstrip antennas and describe the principles for linear, planar and circular arrays, and use antenna synthesis in order to design arrays
- use integral equations in order to calculate numerically radiation diagrams and antenna parameters
- account for the field equivalence principle and apply it to rectangular and circular aperture antennas
- account for the basic methods for antenna measurements
