| Abstract | A dual-band bandpass filter in a millimetre-wave band that uses 0.5 μm GaAs pHEMT technology with two sets of stepped-impedance resonators, which results in a reduction in size, is presented. The two passband frequencies can be flexibly controlled by adjusting the lengths of the two sets of resonators. Two bandwidths can be tuned independently, using external quality factors and coupling coefficients. The fractional 1-dB bandwidths at 60 and 77 GHz are 8.6 and 4.1%, respectively. The measured S 21 values at 60 and 77 GHz are − 2.26 and − 3.9 dB. Good performance is obtained in terms of the excellent microwave properties of the semi-insulating GaAs substrate, which makes this system attractive for wireless communication applications. |

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.
