| Abstract | A trenched silicon-based slot antenna over BCB membrane is investigated. Firstly, a cavity backed slot antenna on a high resistivity silicon (HRS) substrate is designed to achieve wideband performance and high radiation efficiency. The obtained bandwidth is 23% at 25.5 GHz with radiation efficiency of 99%. Then, a trench under both the CPW feed line and the antenna slots is used to replace the cavity. A parametric study is performed to examine the effect of the trench width on both the characteristic impedance of the CPW feed line and the slot antenna performance. In addition, the effect of silicon resistivity on the antenna performance is studied. The final design is based on a 20 /spl mu/m BCB technology over a silicon substrate with resistivity ranging from 11 to 15 /spl Omega/cm. The obtained bandwidth is 37% at 27 GHz with radiation efficiency of 72%. The total used die area is 1 cm/sup 2/. |

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.
