Measuring antenna for 1 - 6 GHz band
Slažanský, Libor ; Lukeš, Zbyněk (referee) ; Nováček, Zdeněk (advisor)
The thesis is focused on the design of a measuring antenna for 1 – 6 GHz band. It deals with the types of log periodic antennas with the the detailed elaboration of log periodic dipole antennas (LPDA). One can find the description of their functions, maximum features and the possibilities to use the asymmetrical feeder. Also there is the procedure of LPDA design and the realization of the design itself including simulation in 4NEC2 programme. In the next part there is a planar LPDA realization with the microstrip-to-balanced stripline balun symmetrization. This design was simulated and tested within the frames of Zeland IE3D programme. The last part contains the measuring results of S parametres as well as beam characteristics of the planar version of LPDA.

Log-periodic antenna for UHF band
Povolný, Ondřej ; Horák, Jiří (referee) ; Láčík, Jaroslav (advisor)
Semestral thesis is focused on the design, analysis and optimization of a log-periodic dipole antenna for UHF measurements. Antenna is introduced with design equations, simulated and optimized to minimize input port reflection coefficient and maximize gain. After that, the antenna cover is introduced and the simulation results are compared for the antenna without cover.
