| Abstract | TiO2 (titania) reinforced low density polyethylene (LDPE) composite is studied as substrate for microstrip patch antenna that is to be used in microwave X band (8 GHz to 12 GHz). Physical, thermal and microwave characterization of the composite is done to confirm the applicability of the composite material as substrate for microstrip antennas. Microstrip antenna with rectangular radiating patch is fabricated on composites with different volume fraction (VF) of filler in polymer as substrate. S11 measurements are carried out on the antenna designed on different substrates using vector network analyzer. To increase the operational bandwidth of the antenna three layer grading of the composite substrate is done. The bandwidth and S11 parameter performance of the antenna is found to be improved by using graded composite as substrate material. Enhancement of directivity is observed for graded substrate as compared to ungraded substrate. |

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.
