| Abstract | A novel 2-D transmission-line metamaterial (TL-MTM) is proposed consisting of two-turns complementary spiral resonators (CSRs) and mushroom structure. For characterization, the circuit parameters are extracted, and the unique 2-D left-handed characteristics are theoretically investigated and further verified by eigenmode calculation. Moreover, a concept of compact factor measuring the miniaturization degrees is first proposed, indicating an efficiency method toward the design of electrically smaller structures. For application, a dual-band and dual-mode antenna operating at n=0 (2.4 GHz, Bluetooth band) and n=+1 (3.5 GHz, WiMAX band) is designed, fabricated, and measured by inserting a 2-D CSRs-loaded TL-MTM cell into the conventional microstrip patch. As a result, the antenna exhibits good impedance matches at both bands feeding with a two-annular-rings slot and comparable radiation gains of 2.45 and 7.65 dB. Also, the antenna is compact, occupying an area of only 0.16λ0 × 0.16λ0. In addition, it is more convenient to realize frequency manipulation by inserting CSRs. |

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.
