Abstract | A novel compact ultra-wideband (UWB) bandpass filter is developed by using microstrip stub-loaded dual-mode resonator doublets. The proposed doublet consists of two parallel but oppositely arranged stub-loaded resonators, and has a significantly widened passband. A UWB filter is designed by cascading three doublets, and eight transmission poles are obtained in its passband. The filter has a passband covering 3.3–10.4GHz, and exhibits sharp attenuations near its passband. The measured frequency response of the filter has a good agreement with the designed one, and the FCC’s indoor limit is satisfied quite well. The minimum strip and gap widths of the filter are larger than 0.1mm. Therefore, critical fabrication precision requirement or complicated backside-aperture-fabrication process is avoided. |

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.
