Baluns
Beran, Vlastimil ; Puskely, Jan (referee) ; Nováček, Zdeněk (advisor)
The baluns (balanced to unbalanced) circuits are used for connection of symmetrical load (antenna, dipole) to unsymmetrical line (coaxial cable). The balun missing causes the load mismatching to antenna feeder and the antenna parameters degradation as result. There are defined the baluns principle of operation and list of types in this work. The baluns created by short sections lines are the scope of project only. The detailed analysis baluns bandwidth and the type application are described in the second part of project. Several recommendation for baluns design is described as project conclusion including parameters optimalization. The function of the balun was verified by measurement. The relevant results are mentioned in the report end.
