Learning outcomes
|
The subject is an introduction to the study of microwave elements. First, students are introduced to the basic types of waves that are applied to different types of transmission lines. Another part of the subject is devoted to the parameters of microwave lines, their measurement and display of measured results in the scattering matrix and on the Smith chart. The key part of the subject is devoted to the basic microwave elements, with emphasis on their theoretical description and construction. Another part of the subject deals with applications of microwave antenna elements. The last part of the subject isfocused on an introduction to the issue of waveguides integrated in the substrate.
A student after completing this subject will know the theoretical foundations of the propagation of electmagnetic waves, and the transmission lines along which these waves propagate. He will also be familiar with basic passive microwave elements and antennas. Last but not least, the student will be competent to perform measurements of microwave elements and antennas and to properly display and evaluate the measured results.
