| Abstract | A textile substrate-integrated waveguide structure using embroidered silver-coated yarn vias as side walls is presented in this paper. This straightforward fabrication technique allows the precise realization of complex arbitrary patterns for guiding electromagnetic waves in wearable applications. The concept retains properties of conventional waveguides such as low-loss propagation and shielding, however in a low profile and flexible implementation. A two-port back-to-back structure with coaxial feeds operating within 5-6 GHz has been designed and manufactured to demonstrate the principle. The realized prototype exhibits an insertion loss of 2.3 dB including two coaxial transitions and a waveguide length of 2.5 wavelengths. Measuring the waveguide performance shows that the structure is very robust to bending, compression and torsion. This opens perspectives for further steps such as efficiency improvements and investigation of more complex waveguide structures including flexible bends and feeds for wearable applications. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
