Abstract | A shaping reflector antenna with similar gains in beam directions at -10/spl deg/, 0/spl deg/, +10/spl deg/ for the application DBS (direct broadcast satellite) is designed and developed. By using this developed antenna, a DBS signal at several satellites on a geostationary orbit can be received simultaneously. The shaping reflector with beam directions at -10/spl deg/, 0/spl deg/, +10/spl deg/ for similar gain is designed and implemented. From the results of simulation for the original reflector antenna, the gain of the focused feed and defocused feed are 35.18 dBi and 33.8 dBi respectively. From the results of simulation for the shaping reflector antenna, the gain is 35.08 dBi for the beam at 0/spl deg/ and 34.14 dBi beams at /spl plusmn/10/spl deg/. For the test results of the shaping reflector, the gain are 34.73 dBi with beam at 0/spl deg/, 34.04 dBi with beam at +10/spl deg/. and 34.22 dBi with beam at -10/spl deg/. |

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.
