Antenna for in-car UWB communication
 Špůrek, Jan ; Puskely, Jan (referee) ; Raida, Zbyněk (advisor)
This bachelor’s thesis is focused on the design of a wireless UWB network inside a car. The project is divided into three parts. In the first part, we describe the design of suitable antennas and feeding structures. The second part is focused on the simulation of a reciprocal communication for each type of the antenna in free space. In the third part, we investigate the effect of interference caused by near parts of the car for each type of the antenna. The results are then evaluated and the most suitable antenna is chosen for realization. The fourth part describes modifications of the antenna for SMA connector, which is necessary for measurement. In the fifth part we discuss measured results and compare them with assumptions from simulations. Results of the thesis are summarized in the conclusion.

Textile slot antenna
 Špůrek, Jan ; Polívka,, Milan (referee) ; Raida, Zbyněk (advisor)
This diploma thesis is focused on design of various antenna structures, based on slot antennas, created in the wider wall of a rectangular-shaped waveguide. As the substrate, it is used a 3D textile material, while its properties are examined. They were designed structures, that operate with linear and circular polarization, and other related structures, that are used for feeding and power division. Structures are designed to operate at central frequency of 8 GHz and its vicinity.
