Self-adhesive copper tape with non-conductive glue is used for DC-block on textiles. As capacitance, overlapping of copper strips was used, and the dielectric is the non-conductive glue of the strips. Two overlapping lengths were realized and measured. Due to the specificity of the textile, especially when worn, the cases of flat structure and when it is in S-shape were measured. The structure is easy to put on and take off and does not damage the textile. By easily correcting the length of the overlap, the range of impervious lower frequencies can be changed.
