Abstract | This paper presents a compact structure, which is characterized by mixed electromagnetic coupling of the composite right/left handed transmission line (CRLH-TL) and source-load cross coupling between the input and output ports. This structure can generate three transmission zeros (TZs) near the bandpass without increasing the overall size of the filter. Meanwhile, in order to get a wide stopband, two open stubs are employed to suppress the harmonic response of the CRLH-TL resonators. Using such a compact structure, a wide stopband bandpass filter is designed, fabricated and measured. Good agreements between simulation and experiment results have been achieved, and good performance in bandpass has been observed with a relative 3-dB bandwidth larger than 17%, and the bandwidth of stopband is $4.0f_{0}$ (f $_{0}=2.1GHz).$ The dimensions of the proposed filter are $0.061λ_{g}×$ $0.073λ_{g}$ (i.e.8.4× $10.5mm^{2}).$ |

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.
