Low-profile directional antenna
Žúrek, Dan ; Pítra, Kamil (referee) ; Láčík, Jaroslav (advisor)
This diploma thesis deals with a study of low-profile directional antennas, followed by design and optimization of parabolic reflector antenna in centimeter and millimeter band. The first part of this work is focused on the analysis of several kinds of directional antennas, mainly on parabolic reflector and on SIW technology, which will be used for final antenna realization. The next part of this project is about the particular concept of the substrate integrated parabolic antenna for 60 GHz ISM band, its simulation and optimization in the CST Microwave Studio software. The final part of this thesis is devoted to the results achieved.

3D textile integrated monopole
Füll, David ; Kufa, Martin (referee) ; Cupal, Miroslav (advisor)
This thesis deals with the design of omnidirectional monopole antennas. Using the parabolic reflector and the directors, the directional characteristics of monopole antennas are modified. This directional antenna, together with the omnidirectional antenna, examines the effect of various materials, the emission characteristics and the input reflection factor, near the antennas. These antennas are made of 3D textile, measured in anechoic chamber and compared to the designed antennas. At the end of the thesis is the summary and evaluation of the result.
