| Abstract | A printed monopole antenna with enhanced bandwidth and reduced size using a bounding box structure is presented in this paper. The initial design comprises a microstrip-fed rectangular monopole with a partial ground structure. A feed line offset, a slit etched on the feed line, an asymmetric transition connecting the feed line and the monopole, and an inverted T-slot embedded in the ground are used to ensure good impedance matching. The design is modified by incorporating a bounding box structure, which introduces additional resonances hence an enhanced impedance fractional bandwidth reaching 156% (0.28 to 2.27 GHz) is obtained as compared to only 72% (0.75–1.60 GHz) realised for a conventional monopole. The electrical size of the proposed antenna is also reduced from 1.01 λ l × 0.60 λ l to 0.39λl × 0.24 λ l (where λ l denotes the wavelength corresponding to the lowest operating frequency of the antenna) using the bounding box configuration. The experimental and predicted results are in good agreement, and the proposed antenna demonstrates good radiation characteristics over the operating bandwidth. The proposed antenna can be applied in DVB (530–860 MHz), GSM850 (824–894 MHz), GSM900 (880–960 MHz) DCS (1710–1880 MHz), PCS (1850–1990 MHz), and UMTS (1920–2170 MHz) systems. |

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.
