A novel stitched transmission line for wearable devices has been manufactured and tested to measure its scattering parameters from 0.04 to 4 GHz. The stitched transmission line which is 150 mm long consists of an inner conductor surrounded by a tubular insulating layer. For shielding purpose, the structure is stitched onto a denim material with a conductive thread with the aid of a novel manufacturing technique using a standard hardware. The S‐Parameters were investigated with three different stitch angles 85 ° , 65 ° , a n d 31 ° through simulation and experiments, demonstrating that the stitched transmission line can work usefully and consistently from 0.04 to 4 GHz. © 2017 Wiley Periodicals, Inc.
