Abstract | In this study, a novel axe-shaped ultra-wideband (UWB) antenna with low-backscattering radar cross-section (RCS) is designed. The designed UWB antenna bandwidth is 3.4–15.5 GHz covering the entire band assigned for the UWB applications. The RCS of the designed antenna is reduced by modifying the geometrical shape. This technique is based on the subtraction of the metal areas which have the minimum current distributions on the surface of the printed antenna. Therefore the backscattering RCS of the modified axe-shaped UWB antenna is reduced up to 10 dB in the whole frequency band while maintaining the radiation performance. The size of the antenna is 0.32λ l ×0.39λ l, where λ l is the wavelength at the lower operation frequency and the fractional bandwidth is 128%. The radiation patterns, scattering characteristics and the RCS of both the modified and reference axe-shaped UWB antennas are simulated and experimentally verified. The simulation and measurement results are in a good agreement. |

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.
