Conical Sierpinski monopole
Všetula, Petr ; Pavel,, Hazdra, (referee) ; Raida, Zbyněk (advisor)
The thesis deals with numerical modeling of planar Sierpinski monopole and modified Sierpinski monopole, outgoing from Sierpinski structure. Next, it focuses on modeling of the conical modified monopole and conical Sierpinski monopole created by transferring of modified structure to conical surface. The properties of these multi-band antennas are verified by simulations in CST Microwave Studio 2009 and compared with the results published in available literature. The conical Sierpinski monopole is then optimized according to specified criteria. The optimized antenna is designed and its properties are experimentally verified.

Cascade Sierpinski monopole
Kadlček, Jiří ; Tkadlec, Roman (referee) ; Všetula, Petr (advisor)
This master’s thesis describes the theoretical analysis of the Sierpinski triangle structure. On the basis of this structure, a planar version of the Sierpinski monopole is firstly designed. Then, by using a transfer of the planar motive to the conical surface, conical and cascade Sierpinski monopoles are designed. All simulations are calculated by CST Microwave Studio 2011. In the thesis, four types of cascade Sierpinski monopole are proposed. The investigated parameters are reflection coefficient, input impedance, radiation properties, polarization and bandwidth. The attention is primarily focused on the design and experimental verification of the selected conical shape cascade Sierpinski monopole set on the bands GSM 900, GSM 1800 and Wi-fi 2,4 GHz.
