Abstract | In spite of its long-standing interest in military areas since the decade of 1960, ultra wideband (UWB) communication systems have received an extensive attention in commercial applications when the unlicensed UWB communications have been allowed by U. S. Federal Communication Commission (FCC) [1]. Moreover, due to the offered wealth of advantages, such as delivering high resolution reliable data, increasing system capacity and capability of reducing the power consumption, UWB systems have widely been exploited in the wireless short-range high-throughput communications operating over the frequency range of 3.1GHz-10.7GHz. In the allocated band for UWB systems, the frequency band of 5.15–5.825GHz is limited by IEEE 802.11a for wireless local area networks (WLANs). In order to prevent the interference between UWB communications and WLAN systems, a rejection band is necessary to filter out the undesired WLAN signals. Accordingly, an ultra wideband antenna with a band-notch characteristic can be an alternative choice to the use of a distinct stop-band filter in the system. UWB monopoles or slot radiators are some typical planar configurations, which are recently introduced for this purpose [2–4]. In these antennas, by manipulating the current distribution using a slot or applying a parasitic element, a deep notch band can be created around the frequency bandwidth of the interference signals. |

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.
