| Abstract | In this study, a multiband 8-element MIMO antenna operating at LTE 800/2300/2500 MHz, GSM 850/900/1900 MHz, UMTS, DCS, PCS, IMT, WLAN 2400 MHz, WiMAX 3500 MHz and Wi-Fi 5800 MHz is proposed for handheld devices. The proposed antenna comprises of radiating elements and novel decoupling structure to reduce the mutual coupling. To obtain multiple resonances, F-shaped monopole, C-shaped strips, L and S-shaped monopoles are integrated to form the complete radiator. The protruded ground plane with inverted π-shaped slot acts as the decoupling element. The eight elements are arranged in a certain fashion to achieve spatial and polarisation diversity. The impedance bandwidth achieved is 170, 1070, 400 and 700 MHz. The isolation is >20 dB in all the desired operating bands. The simulated peak gain and efficiency of the antenna at the four operating bands are 4.8/6.3/5.4/4.7 dBi and 75/90/80/83%, respectively. Furthermore, the envelope correlation coefficient, the apparent diversity gain and effective diversity gain are calculated and presented. The obtained measured and simulated results are in good correlation with each other. |

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.
