Abstract | New configurations of folded and compact planar ultra-wideband filters with source- load cross coupling and impedance stubs are presented. Stepped impedance resonators and coupled-line sections as inverter circuits form the basic filter structures. High-low impedance lines connect individual resonators. Effective techniques such as open-stub lines and source-load cross coupling are utilized in order to add return-loss poles in the pass-band and create transmission zeros in the lower/upper stop-band region. Several filters are designed with 3dB fractional bandwidths of 80 percent, computed insertion losses better than 1 dB and return losses larger than 10 dB. Rejection levels in the upper/lower stop-bands are better than 35 dB. The designs are verified by results obtained with commercial electromagnetic software packages. |

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.
