| Abstract | This paper presents a novel compact dual-polarized antenna system that integrates two-stage low noise amplifiers (LNA) from operation from 2.320 GHz to 2.345 GHz. The developed antenna system incorporates a low profile annular ring patch antenna with a 90deg phase delay element for circular polarization (CP) and a reactively loaded monopole linear polarized (LP) antenna. The CP annular ring patch antenna is fed from underneath while maintaining the phase difference of 90deg between the two feeding points, resulting in more than 50% volume reduction compared with previous work. In addition, the demonstrated antenna exhibits good axial ratio with for a wide range of elevation angle. Furthermore, dual-path two-stage LNA is implemented with low power consumption, high isolation, and a single port for both dc bias as well as RF output. The gains of the antenna system with LNA are measured to be 31.3 dBi and 21.9 dBi for the CP, and the LP, respectively |

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.
