| Abstract | A simple technique for achieving enhanced isolation between two long-term evolution (LTE) antennas operating at the LTE700/2300/2500 band for the multiple-input multiple-output (MIMO) operation in the laptop computer is presented. The two antennas are mounted along the top edge of the supporting metal plate, which is generally disposed on the inner surface of the upper cover of the laptop computer. Improved isolation (simulated S21 better than −17 dB in the LTE700 band and −30 dB in the LTE2300/2500 bands) between the two antennas is easily achieved. By arranging a pair of the isolation elements at two separate null current locations of the excited surface current distribution of the LTE700-band modes of the two antennas can improve isolation in the LTE700 band. It can effectively cause weaker surface currents flowing along the top edge of the supporting metal plate. Over the lower and upper bands, the antenna efficiencies are about 46–58% and 50–68%, 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.
