This course introduces the basic principles of high frequency technologies and especially focuses on tackling the crucial problem of a telecommunication engineer, which is data (and energy) transmission with minimum distortion and attenuation. Firstly, the propagation of EM waves in infinite space is studied by stressing attenuation and distortion issues. Then, the propagation in transmission lines is examined with emphasis on the composite resistance of the line. The problem of loading matching is also investigated and different load matching techniques are evaluated. At a following stage, the mechanisms of waveguiding are investigated with emphasis on the waveguiding through metallic orthogonal and cyclic waveguides. Additionally, the properties of coaxial lines and microstrips, which are widely used in hybrid or integrated microwave circuits, are also studied. The analysis of the aforementioned waveguiding phenomena will provide the students the necessary skills to analyze other types of waveguides. The last part of this course is dedicated to the theory of microwave networks, which is based on the use of scattering matrices (S-parameters). During the course, the students are assigned homework exercises, as well as practicing with CAD tools for the aforementioned subjects.
