| Abstract | An efficient procedure is developed to synthesize the radiation pattern of a planar antenna array in the near zone of array aperture, which can be used for the applications of RFID reader as illustrated in Fig. 1 [1,2]. In this case, the objects under detection may locate in the near zone of antenna. The presented work appears to be more effective than a conventional near-field focused array antenna [3] because the field distribution in the target zone can be optimized, and can help to reduce the interferences. In this synthesis scheme, we utilize a global basis set to span the array excitation as previously proposed in [4], where each basis's excitation will radiate a near-field focused spot beam in the target area, and serves as local basis functions to synthesize the contoured pattern in the target area. The unknown coefficients of array's basis set are then found via a MLSE technique. It is found that only a small number of basis functions are sufficient to resemble the radiation pattern, and make the present approach very fast. |

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.
