Abstract | Different from the traditional antennas for narrow-band systems, an Ultra Wide Band antenna provides new challenges for designers such as how to achieve the very wide impedance bandwidth (7.5 GHz) while still maintaining high radiation efficiency and minimizing the pulse distortion. Two Archimedean monofilar micro-strip antennas using Electromagnetic Band Gap (EBG) structure for UWB are developed in this paper. In these antennas, the EBG plays a role of ground plane of antenna in order to get a low-profile as well as unidirectional radiation. EBG also helps to improve the antenna performance significantly. In the first prototype, the uniplanar EBG structure is employed as a ground plane and in the second one, the mushroom EBG structure is embedded in order to enhance the antenna radiation pattern. The performance of two antennas is compared to the antenna using a perfect ground as well as is compared each other based on the simulation and measurement results. |

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.
