Increase of operation frequency of printed antennas
Havlík, Vojtěch ; Láčík, Jaroslav (referee) ; Raida, Zbyněk (advisor)
The thesis is focused on the design of a slot antenna integrated into a textile substrate. In the thesis, antennas operating at the frequency 5.8 GHz and 24.125 GHz (ISM bands) were designed. Functionality of the antennas was verified by simulation performed in the program CST Microwave Studio. The antennas consist of a textile integrated waveguide and a coplanar waveguide which adapts the waveguide characteristic impedance to 50 of the input coaxial connector. As a substrate, we used a 3D textile material.
Reconfigurabe Waveguide Divider
Cupal, Miroslav
The design and implementation of the textile integrated waveguide (TIW) switch for ISM band is presented. The traveling electromagnetic wave is controlled by conductive posts with a circular slot. PIN diodes are used for switching electromagnetic wave to two directions. The simulations results are presented as parametric analysis.
