| Abstract | Satellite and terrestrial (wireless) communication systems require high functionality (i.e., direction finding, beam steering, reconfigurability, frequency agility, and broadband) to address multiservice, multiband, and multistandard operation in a confined small volume. Although there are existing technologies with such functionality, the associated devices are large and heavy, and often limited in functionality. However, recent developments in conformal miniature ultra-wideband apertures with phase amplification of the received/transmitted signal provide for a new direction in fulfilling the lofty goal of miniature antenna direction finding apertures. A way to overcome reduced resolution is to amplify the phase difference between adjacent elements. In this paper, we propose to enhance the phase difference between adjacent elements (as close as λ/10 apart) by controlling interelement coupling. The design is achieved by casting the array elements in a T- or π-resonator network. Optimization leads to an antenna-circuit structure that achieves phase amplification. This equivalent circuit mimics the hearing capabilities of some small insects (e.g., the parasitoid Ormia ochracea). |

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.
