Dissertation thesis written by Kamil Pítra was focused on the development of circularly polarized antennas for terahertz sources. The research was done in a tight cooperation with prof. Hartnagel from Technical University of Darmstadt. Outputs of the research were published in Radioengineering, and several proceedings of European conferences. At present, a paper Low-Profile Circularly Polarized Antenna Exploiting Fabry-Perot Resonator Principle is in a review process of IEEE Antennas and Wireless Propagation Letters. During his studies, Kamils spent several months in Technical University of Darmstadt with the group of Prof. Hans Ludwig Hartnagel. He also attended the European School of Antennas and International Travelling Summer School on Microwaves and Lightwaves. An original contribution of the thesis written by Kamil can be found in an appropriate combination of a planar radiators fed by a cross-slot aperture, an electromagnetic band-gap substrate and a planar lens. The described design resulted in a very compact planar antenna which is suitable for the operation at (sub)millimeter-wave frequencies. During PhD studies, Kamil was engaged in the design of high-power antennas for DVB-T broadcasting in frame of the contract for TESLA Holding. Kamil significantly contributed to the national project Millimeter-wave electromagnetic structures for biomedical research. Outputs of Kamil’s work are highly appreciated, and his thesis is recommended to be defended.
