| Abstract | This study presents a unidirectional bowtie array antenna with incision gap for a digital video broadcasting-T2 base station application. The antenna element consists of a bowtie radiator with incision gap on top of a square reflector. The element achieves a bandwidth of 82.35% for ∣S 11∣ of <−10 dB, covering a frequency range of 450–1080 MHz. The antenna array comprises of four identical antenna elements mounted vertically to form an antenna array. The simulated and measured results of the antenna array show a good impedance matching for ∣S 11∣ of <−10 dB along a frequency range of 450–1014 MHz (77.05%). The measured gains are 13.4–16.1 dBi along an operating frequency of 470–862 MHz with the narrow half-power beamwidth in the vertical plane of ∼15° ± 5° and the half-power beamwidth in the horizontal plane of ∼60° ± 5° for a frequency range of 470–666 MHz and 90.5° for 862 MHz. The radiation pattern is degraded at the frequency higher than 950 MHz. |

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.
