| Abstract | A unidirectional dual-polarised antenna is presented, by applying a cavity-backed annular slot and two mutually perpendicular microstrip feed lines. To improve the isolation between two ports of the designed antenna, a pair of conductor strips is introduced at the opposite side of the feed lines and a metal cylinder into the cavity centre. Aimed at 2.4 GHz wireless local area network systems, a prototype antenna has been fabricated based on the FR4 substrate. The measured results show that an isolation value of over 33 dB can be attained and the co-polarised level is 30 dB larger than the cross-polarised in the main radiation direction. In addition to compact structure, the operating band with about 5 dBi antenna gain indicates the proposed antenna is suitable for indoor multiple-input–multiple-output (MIMO) base station systems. |

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.
