Antennas for GSM bands
Rousek, Jiří ; Pokorný, Michal (referee) ; Pítra, Kamil (advisor)
Bachelor thesis deals with miniaturization techniques of the planar inverted-F antenna (PIFA). In bachelor thesis were simulated antennas for the GSM bands using meandering of the radiating patch, capacitive load and U-slolts. Influence of parameters of each miniaturization techniques on the antenna size and parameters were studied. The process of designing the antennas is described in detail. Selected models of antennas were adapted to given dielectric substrate and constructed. The measured results are presented and compared with simulations.

Multiband embroidered antennas
Fraj, Lukáš ; Olivová, Jana (referee) ; Raida, Zbyněk (advisor)
This thesis is engaged into the designing embroidered dipole multiband antenna. Numerical models of the antenna, operating at GSM 900 Mhz, PCS 1900 MHz and WLAN 2450 MHz bands, were designed using finite-element ANSYS HFSS software. Simulations of this antenna in the free space and near the human body, interpreted by numerical model, are compared with each other. Afterwards the antenna is optimized for 900 MHz, fabricated and measured. All achieved results are compared with the pattern.

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.

Multiband antenna for GSM (900/1800)
Kalánek, Jakub ; Olivová, Jana (referee) ; Šporik, Vladimír (advisor)
This work deals with the principles on which they are based multiband antennas, especially for GSM (900/1800). It then focuses on different ways you can implement these multi-band antennas, mainly deals with structures that can be easily realized using planar technology. These antennas was designed and optimized in electromagnetic simulation software. Selected antenna was practically realized.
