Analysis of planar junction in millimeter bands
Ambros, Martin ; Oliva, Lukáš (referee) ; Lukeš, Zbyněk (advisor)
This diploma thesis solves possibilities of transitions between waveguides and hybrid types of integrated microwave circuits. It describes the basic ways of solutions this transitions in both longitudinal and transverse as well. In thesis is also mentioned the principle of SIW technology, which is in this transitions widely used. The practical part is focused on the modeling and analysis of selected structures in CST MW Studio. Modeled structures are optimized for the lowest possible value insertion loss transition and are adapted to the characteristic impedance on 50. Selected structures are recalculated to a lower frequency band, realized and results of their simulation verified by measurements.
