Antennas for milimeter-wave bands
Pítra, Kamil ; Svoboda, Petr (referee) ; Raida, Zbyněk (advisor)
This thesis describes design and experimental verification of three types of the wideband antenna Bow-tie antenna, Vivaldi antenna and Spiral antenna. The tracked parameters are bandwidth, input impedance, gain and directivity patterns. Next step is design of millimeter-wave horn antennas. Attention is turned to the proper construction of a wideband feeder of the horn. For the final antenna structure, a bow-tie dipole and a Vivaldi antenna were chosen. The antenna construction is aimed to provide a wide bandwidth on one hand and a high gain on the other hand.

Wideband antenna for the frequency range from 5 GHz to 10 GHz
Hebelka, Vladimír ; Oliva, Lukáš (referee) ; Řezníček, Zdeněk (advisor)
The design and manufacturing of a wideband bow-tie antennas for the frequency range from 5GHz to 10GHz are described on this thesis. In the first part of this thesis is decsribe a several type of bow-tie antennas. Next part provides the design of bow-tie antennas and optimalization in CST microwave studio software. At the end of the thesis are compare simulation results and measured results of bow-tie antennas.
