| Abstract | A compact, planar, low profile microstrip line-fed quad-band antenna is presented with operating frequencies at 2.5/3.6/5.5/7.5 GHz. The antenna consists of a rectangular split-ring resonator (SRR), a stepped impedance resonator (SIR) inside the ring, a slot on the SIR and a pair of SRRs either side of the matching network. Each of the resonators generates its own individual band which is independently tunable. The antenna is compact in size having dimensions 0.10λ 0 × 0.13λ 0. The radiation patterns are omnidirectional and bilateral in the H-plane and the E-plane, respectively, at all the resonance frequencies. The simulated results are observed and reported in terms of S-parameters, gain and radiation patterns. A prototype structure is fabricated and the measured results are compared with those obtained from the simulation. |

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.
