| Abstract | A reconfigurable X-band microstrip bandpass filter based on the stepped impedance resonator topology with two folded stubs is proposed. Reconfiguration is enabled in the microstrip filter using positive–intrinsic–negative (PIN) diode and the proposed filter performs frequency switching between uplink and downlink X-band services. The prototype filter is realised ideally using open-circuit and short-circuit conditions that are designed in a way similar to the design using PIN diodes that provide the same results. From the simulation and measured results, it is inferred that by altering the ON/OFF states, the filter can work from downlink frequency range of 7.25–7.9 GHz to the uplink frequency range of 8.00–8.4 GHz. Comprehensive studies are conducted on a fabricated prototype to assess its performance from which encouraging results are obtained. |

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.
