| Abstract | A dual-sleeve wideband monopole antenna with loaded plasma cylinders is proposed for shipborne systems in lower very high frequency (VHF) range. The monopole with sleeves, engineered as vertical polarised element, operates at the frequency from 30 to 100 MHz. It performs good radiation ability with low elevation angle in E-plane. The monopole antenna height over feed point is 0.33λ at the lowest band. Plasma cylinder array as reflector is mounted above the monopole to restrain the deformation of patterns. Impedance and pattern measurements are conducted; the VSWR ≤ 2:1 bandwidth of the sleeve antenna is >107%. Unmanned aerial vehicle system is introduced to measure the radiation patterns at 110 MHz. Obtained results confirm that the proposed antenna is a variable candidate for communications with ships and flying vehicles in anti-stealth systems. |

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.
