| Abstract | Reflector antennas with elliptical apertures are often seen to be advantageous in satellite communications and radar applications. Utilization of an elliptical aperture is typically motivated by the required radiation patterns, and the reduced weight and cost. The central issue in the design of such elliptical reflector antennas is re-distributing or re-directing the feed field to the reflectors in the manner that the desired beam characteristics are obtained. It becomes a challenging task when a more complex radiation pattern such as a contoured-beam is to be generated from an elliptical reflector antenna that uses one circularly symmetric feed. In this situation, the field-redirection can only be achieved through reflector shaping. In the paper, the diffraction shaping technique based on an orthogonal global surface expansion and optimization techniques is employed to shape an elliptical dual-reflector antenna, and the result compared with that using a circular reflector antenna.< |

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.
