| Abstract | One of the most recent innovations to overcome the demands for increased capacity nowadays, is that of deploying smart antennas for wireless communications. A smart or adaptive antenna is defined as one that combines multiple antenna elements with a signal processing capability to optimize its radiation or reception pattern automatically, in response to the signal environment. The paper concentrates on the use of circular arrays for smart antennas. An overview of smart antennas is provided. The necessity for implementing uniform circular arrays (UCAs) for adaptive antennas and several adaptive algorithms applicable to UCAs are mentioned. For the simulation process, a specific UCA configuration has been examined, where adaptive beamforming was performed in both azimuth and elevation (for fixed elevation and azimuth angles, respectively) according to certain requirements in the design (directions of signals of interest and signals not of interest) imposed by the wireless environment. |

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.
