| Abstract | A dual-antenna system for smartphones with Long Term Evolution (LTE)/Wireless Wide Area Network (WWAN)/Wireless Local Area Network (WLAN)/Worldwide Interoperability for Microwave Access (WiMAX) operations is presented and studied. The proposed dual-antenna system consists of two symmetric antenna elements and a folded dual inverted L-shaped ground branch (FDILGB). Each antenna element includes a driven branch and a parasitic ground branch. To improve the antenna efficiency, the parasitic ground branch is studied and optimized. The FDLGB is applied to reduce the mutual coupling between the two closely spaced antenna elements and achieve better impedance matching. The measured operating bands with |S11| lower than - 6 dB cover 698-974 and 1699 - 4019 MHz for the fabricated prototype. Within the operating bands, the measured |S21| is lower than - 10 dB. Based on the measured 3D radiation patterns, the envelop correlation coefficient, the mean effective gain and the diversity gain of the proposed dual-antenna system are calculated, and good results are obtained. |

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.
