Dielectric resonator antenna
Štarha, Michal ; Pokorný, Michal (referee) ; Láčík, Jaroslav (advisor)
This project deals with using of dielectric resonators as antennas. There are discussed possibilities feed of these antennas, as feed probe, feed of microstrip line, aperture coupling, or coplanar waveguide. Then there is a simple example design dielectric resonator antenna and its modeling in CST Microwave Studio. The designed antenna is fabricated and measured.

Broadband dielectric resonator antennas
Zbořil, Jan ; Polívka, Milan (referee) ; Raida, Zbyněk (advisor)
The diploma project deals with the numerical modeling, implementation and measurement of dielectric dipoles excited by a coaxial probe. Attention was turned to shape optimization of dipoles from the viewpoint of ultra wideband parameters in the band group 6. (“Bandgroup 6“). Two antennas exhibiting the best parameters were fabricated. Results of measurements were compared with simulation results. Simulations and measurements were in agreement. For the simulations, we use program CST Microwave Studio.

3D printed dielectric resonator antenna
Lungu, Masauso ; Láčík, Jaroslav (referee) ; Zechmeister, Jaroslav (advisor)
Tato bakalářská práce se zabývá návrhem a výrobou válcové dielektrické rezonátorové antény pracující na kmitočtové pásmu ISM 5,8GHz. V této práci jsou popsány různé metody buzení antény. V CST Microwave Studio byly navrženy a prozkoumány dva numerické modely válcové dielektrické rezonátorové antény, jeden s koaxiální sondou a druhý se štěrbinovým napajení. Model se štěrbinovým napajení byl poté vyroben technologií 3D tisku a následně byly jeho vlastnosti změřeny a ověřeny simulovanými výsledky.

Circularly polarized dielectric resonator antenna
Zechmeister, Jaroslav ; Kufa, Martin (referee) ; Mrnka, Michal (advisor)
This thesis discusses the design circularly polarized dielectric resonator antennas for ISM band 5,8 GHz. In this work are explained and compared different ways of resonator feeding. There are also discussed the possibility of generating a circular polarization from a aperture feeding. Two methods of generating circular polarization in dielectric resonator antennas are simulated in CST Microwave Studio. This methods are C-shaped slot and cross slot. For antenna with cross slot feeding is also simulated effect of the manufacturing process to characteristics proposed antenna. The antenna is made, measured and the results are compared with simulations.
