Position indikator behind the wall
Slavíček, Radek ; Friedl, Martin (referee) ; Szabó, Zoltán (advisor)
This bachelor´s thesis is focused on explaining of basics of electromagnetism and principles of resonant circuits. These solutions are used for design the indicator opposite position. The next step of document is solution by using magnetic field for design of transmitter and receiver antennas for electronics devices. The final products are solved as the best way for the design. Development process is described step by step in individual chapters.

Periodic structure design for directivity enhancement of dielectric resonator antennas
Slavíček, Radek ; Horák, Jiří (referee) ; Láčík, Jaroslav (advisor)
The thesis deals with linearly polarized dielectric rectangular resonator antenna (DRA) operating in the basic mode TEy11 and higher order mode TEy131 at f0 = 10GHz surrounded by an electromagnetic band gap structure (EBG). The dielectric resonator antennas, the EBG structure were designed and a method of integration of both components was developed. The simulated results show a significant improvement of the radiation pattern in the E-plane radiation pattern (narrower main beam, lower level of side lobes, higher directivity) in comparison to a conventional DRA. This was verified by the TEy11 measurement.

Performance Enhancement Of Dielectric
Resonator Antenna By Ebg Structure
Slavíček, Radek
The paper deals with a linearly polarized dielectric resonator antenna (DRA) operating in the basic mode TEy δ11 at f0 = 10 GHz surrounded by an electromagnetic band gap structure (EBG). A dielectric resonator antenna, an EBG structure were designed and method of integration of both components was developed. The simulated results show a significant improvement of the radiation pattern in the E-plane (narrower main beam, lower level of side lobes, higher directivity) in comparison to a conventional DRA.
