| Abstract | A fully-printed and low-profile bow-tie antenna is proposed, which exhibits multi-band performance by loading a bow-tie antenna with series capacitive gaps and shunt inductive strips, to form an asymmetric two unit-cell NRI-TL loaded antenna. It is demonstrated that the resonant behaviour of the antenna can be adjusted by changing its geometrical parameters, which in turn tune the transmission-line and loading parameters of each NRI-TL unit cell. Both quad-band and tri-band versions of the antenna are shown. The tri-band version of the antenna achieves a −10 dB bandwidth of 44 MHz around 1.12 GHz, a bandwidth of 820 MHz, from 2.61 GHz to 3.43 GHz, and a bandwidth of 86 MHz around 6.47 GHz. The low-frequency resonance at 1.12 GHz corresponds to a 48% reduction in the resonant frequency compared to the lowest resonant frequency of the unloaded bow-tie antenna. The antenna has a total size of 50×10×0.79 $mm^{3}$ or 0.187×0.037×0.003λ0 at 1.12 GHz, and throughout the operating bands the gain and efficiency vary from −3.08 dBi to 2.21 dBi and 52% to 96%, respectively. |

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.
