| Abstract | This report summarizes some of the recent results at FOI with respect to multi-band and reconfigurable front-ends for flexible and multi-functional RF systems. Firstly, we report on a frequency agile X-band smart skin digital beamforming antenna based on using an 8-10 GHz tunable active filter and an image rejection mixer in a receiver GaAs MMIC. Secondly, we have also investigated the possibility of using RF MEMS based reconfigurable matching networks for realizing tunable bandpass LNAs with even wider tuning ranges (e.g. 6-10 GHz could be possible according to our simulations). Finally, we study a system concept for a Ka-band multi-functional electronically steerable antenna (ESA) on a small UAV based on using sub-arrays with low-loss MEMS phase shifters. The results show that adequate RF performance (in terms of 2 dB of average losses at 35 GHz) can be possible to achieve with a Ka-band 4-bits MEMS phase shifter design made on quartz. |

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.
