Web application for antenna analysis
Večeřa, Štěpán ; Kadlec, Petr (referee) ; Raida, Zbyněk (advisor)
Měla být vyvinuta webová aplikace pro zjednodušenou analýzu anténních polí. sestávající z drátových dipólů nebo náplasťových prvků. Původně se předpokládalo, že výpočetní jádro bude vyvinuto v prostředí MATLAB a webové rozhraní v jazyce Python. Studie proveditelnosti ukázala, že plné v jazyce Python je výhodné. Vyvinuté funkce Pythonu pro analýzu a syntézu antén jsou stručně popsány a jejich funkčnost je ověřena v prostředí MATLAB.

Improving antenna parameters by the application of metamaterials
Šporik, Vladimír ; Hertl, Ivo (referee) ; Raida, Zbyněk (advisor)
The thesis is focused on the design of a planar resonant-type antenna, which exploits a proper combination of left- and right-handed properties of transmission lines. This transmission line is called CRLH TL and is based on Sievenpiper mushroom structure. Advantages of the proposed antenna concept are demonstrated by a detailed comparison of its basic properties with the properties of a conventional patch antenna.

Workplace for testing of the laser diodes
Zemánek, Martin ; Tannenberg, Milan (referee) ; Wilfert, Otakar (advisor)
Bachelor thesis is focused on laser diodes and proposal in their workplace testing, followed by constructing workplace with program for graphical output with processed values of measurment. Laser diodes paramaters as optical power, symmetry of the laser beam and radiation characteristic are the objective of this thesis. Thesis includes the theory of laser diodes, device list, workplace layout, description of measurment methods, followed by measuring and and processing the values in program with graphical output. Resulting values are compared with catalog data.

Radar receiver beamforming implementation in FPGA
Bárta, Jakub ; Dvořák, Vojtěch (referee) ; Bohrn, Marek (advisor)
This thesis deals with design and implementation of digital beamformer for 3D radar. The text of this thesis contains derivation of beamforming algorithm and detailed description of it’s implementation on development kit with Cyclone V circuit. At the end of the thesis the beamformer design is verified and it’s further usage is discused.
