Textile Integrated Waveguide Components
 Cupal, Miroslav ; Polívka, Milan (oponent) ; Joler, Miroslav (oponent) ; Raida, Zbyněk (vedoucí práce)
The thesis is focused on the research of structures based on the Textile Integrated Waveguide (TIW). Attention is turned to the electrical characterization of textile materials (textile substrates, yarns) to be used for the implementation of textile-integrated antennas, reconfigurable and active circuits. The thesis deals with the design of multilayer transitions between a microstrip line on a conventional substrate and textile-integrated lines. Second, a concept of the textile-integrated switch is presented. The switch is controlled by conductive posts which are connected or disconnected by DC driven PIN diodes to form open or closed walls. Finally, the design methodology for textile-integrated circularly polarized antennas operating in ISM bands up to 24 GHz is proposed. All the design procedures were verified by simulations and measurements of real samples manufactured by screen-printing using a silver polymer paste. For bonding semiconductor components, conductive silver adhesives were used. Screen-printed components were compared with reference structures manufactured from a self-adhesive copper foil.
