Planar textile transmission lines

This paper deals with the design and realisation of planar transmission lines on the textile substrate. Many types of different planar transmission lines are known very well and are commonly used for connection of electronics components, electronic equipment, and system. Currently, there is an effort to integrate electronic devices and components into the clothes. So there are requirements on their electrical connection quality and using technological processes for textile and electronics together. Conductive hybrid threads may be used for the creation of embroidered planar transmission lines on the textile substrates directly. For these embroidered transmission lines, the electrical parameters are very important, so their behaviour on the high frequencies has to be observed mainly. The test samples of embroidered coplanar strips and coplanar waveguides were created, and their scattering parameters measured. Obtained results can be useful for the next research in the field of smart textiles
