Wideband low-profile circularly polarized antenna array
 Benites Ayala, Jhony Cristian ; Cupal, Miroslav (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis is focused on the study of a novel type of wideband low-profile circular array antenna with circular polarization and high gain. The aim of this thesis is to design, optimize and implement the proposed antenna for a 5.5 - 7 GHz frequency band. The thesis deals with theoretical fundamentals in order to subsequently present the concept of the antenna. Furthermore, it describes its design and implementation stages. The antenna was designed in the full-wave program CST Microwave Studio and fabricated on dielectric substrate. Both simulated and measured property results are evaluated in the conclusion.

Chinese foreign policy: the rhetoric shift from keeping low profile to assertiveness
 Liškutín, Kamil
The goal of the thesis is to answer the question whether the new leader, Xi Jinping, has indeed moved away from more low profile oriented strategy. The first part deals with both theoretical and methodological background. The second part uses the background to answer the question via speech comparison and analysis in terms of speech coding. Moreover, the results are tested so as to challenge certain findings resulting from speech comparison due to possible errors.
