On the Techniques to Develop Millimeter-Wave Textile Integrated Waveguides Using Rigid Warp Threads

Two millimeter-wave textile integrated wave- guides (TIWs), which only differ in the employed substrate, have been designed, manufactured, and experimentally characterized. Both waveguides are based on the conventional substrate integrated waveguide technology while being fully integrated in textile. The manufactured prototypes have been characterized by using a back to back TIW to rectangular waveguide transition. The theoretically predicted behavior of the prototypes has been experimentally verified.
