| Abstract | Internet of things (IoT) is a complex network of physical objects capable of wirelessly communicating with each other. For implementing such an enormous network, the authors design a compact dual-band antenna with simple structure. By folding the radiating element and resetting the ground plane, the whole size of the designed antenna is only 14 mm × 14 mm same as a thumbnail, which makes the designed antenna easy to fabricate. The fabricated antenna can operate (return loss S 11<−10 dB) at two operating bands of 3.4–3.6 GHz for 5G and 5.725–5.825 GHz for 5.8G Wi-Fi, which means it is able to connect the IoT nodes to the Internet through 5G and Wi-Fi network. Simulation and measured results demonstrate that (i) folding the L-shaped stub into U-shaped can reduce the dimension of antenna, and resetting the ground plane structure to parallel to the feed-line can achieve better impedance matching between the designed antenna and the sub-miniature-A (SMA) connector in both operating bands; (ii) the fabricated antenna is able to fully cover the operating bands of 5G at 3.4–3.6 GHz and Wi-Fi at 5.725–5.825 GHz, and can achieve nearly omnidirectional radiation patterns over the two operating bands. |

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.
