SIW slot antenna
Martinec, Matěj ; Puskely, Jan (referee) ; Pítra, Kamil (advisor)
This work is dealing with the design of waveguide slot array antenna and SIW slot antenna with coaxial and microstrip feed operating in 5,6 GHz frequency in Wi-Fi frequency band of IEEE 802.11ac standard. For design of these antennas were used calsic methods and each of this parts were optimised in CST Microwave Studio. In this programme were optimised parameters of each part to occupy widest bandwidth of antenna, which was in conflict with the proper function of antenna. All antennas were compare between each other in light of selected parameters and suitable antenna has been chosen.

Reconfigurable slot antenna array
Weigel, Filip ; Pítra, Kamil (referee) ; Raida, Zbyněk (advisor)
This master's thesis deals with the basic principles of slot antennas. Models of antennas were simulated in a selected electromagnetic simulator CST MICROWAVE STUDIO (CST MWS). There are several models of slot antennas which are optimized for communication in the car at a frequency 8 GHz.

Substrate integrated waveguide filter
Vyskočil, Jiří ; Tkadlec, Roman (referee) ; Láčík, Jaroslav (advisor)
In this thesis is discussed a filter design of a band-pass substrate integrated waveguide filter on the frequency of 5 GHz. It also includes design theory, filter synthesis, filter analysis in the program CST Microwave Studio® and the results of measurement on a vector network analyzer. The analysis results are compared with the measured results. Good agreement between simulated and measured results is observed.

Microstrip lowpass filter
Kubín, Petr ; Pítra, Kamil (referee) ; Vágner, Petr (advisor)
This thesis is focused on the design of an elliptic microstrip low pass filter. In the introduction, there is discussed theory of the filter design with discrete components. Then, the following part describes the design of the microstrip filter with distributed parameters. To simulate the characteristics of the designed filter structure, the simulator Ansoft Designer V2 was used. This software was also used for final optimization of the microstrip filter.

Reconfigurable patch antenna
Zlatníček, Radek ; Polívka, Milan (referee) ; Raida, Zbyněk (advisor)
The master's thesis deals with the design and implementation of a reconfigurable patch antenna. The antenna is fed by a microstrip transmission line. To the microstrip feeder, tuning stubs are connected. Each stub matches the input impedance of the antenna to 50 ? for different operation frequencies. Stubs can be individually connected to the feeder by PIN diodes; operation frequency of the antenna can be switched that way. In the project, the antenna is initially designed for antenna substrate RO3006. Then, the design will be converted to the substrate ARLON AD600 selected for the realization. In the project, modifications of stubs will be proposed to properly connect the PIN diodes. Functionality of the designed antenna will be verified by modeling in Ansoft Designer. The last part will be dealt with implementation of the antenna and the experimental measurement of their properties.
