| Abstract | This letter highlights the potential of inkjet-printing on molded interconnect device technology for the realization of ultrawide band (UWB) antennas. Low-cost thermoplastic acrylonitrile butadiene styrene polycarbonate (ABS-PC) substrate is selected for its promising mechanical and thermal properties. First, electrical characterizations of bare ABS-PC are done using resonance cavity method and then the measurements of S-parameters of two 50 Ω-CPW transmission lines, allow the extraction of both relative permittivity and RF losses. Inkjet printing of silver nano ink is used to fabricate those CPW lines on the top of a 2-mm-thick ABS-PC. The measurements show a relative substrate permittivity equal to 2.8 with conductive and dielectric losses of 19.5 dB/m and 2.4 dB/m at 2 GHz, respectively. Then, an UWB antenna based on a half circular disc monopole and a rectangular patch with two steps is designed and realized by inkjet on ABS-PC. This printed antenna provides a good impedance matching over the entire bandwidth of 3 GHz-13 GHz. Radiation pattern is omnidirectionnal in both E and H planes until 5 GHz and is deformed at higher frequencies due to the higher order modes. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
