| Abstract | A decoupled dual-antenna system for Long Term Evolution (LTE)/Wireless Wide Area Network (WWAN) smartphone applications is presented. The proposed dual-antenna system is composed of two symmetric antenna elements and two crossed neutralization lines. The antenna element of the proposed dual-antenna system consists of a driven branch and a parasitic ground branch, generating a couple of resonant modes. The dual-antenna system incorporates two crossed neutralization lines to reduce the mutual coupling between the two closely spaced antenna elements. A measured impedance bandwidth with S11 lower than -6 dB over 702-968, 1698-2216, and 2264-3000 MHz is obtained. Within the operating bands, the measured S21 is lower than 10 dB. Based on the measured 3-D radiation patterns, several important figures of merit for the diversity performance of the dual-antenna system are calculated, including the envelop correlation coefficient, the mean effective gain, and the diversity gain, 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.
