| Abstract | A dual-band dual-polarized planar passive phased array feed was designed and simulated, with four highly isolated ports and polarizations. The feed design provides an important feasibility demonstration for the deployment of a satellite transponder that transmits a downlink signal at 17.3-17.8 GHz, referred to as reverse band (RB), in the same orbital slot as an existing Ku-band satellite. The design utilizes a multilayer printed circuit board (PCB) to separate the complex feed distribution networks required for the four-port antenna. Simulation results indicate that the feed receives signals in dual linear polarization at Ku-band and dual circular polarization at RB with isolation between all ports better than 20 dB. With the feed illuminating a reflector antenna, the aperture illumination and radiation efficiencies are approximately 70% and 80%, respectively, for all ports, representing one of the most complex yet efficient reported planar array feed designs in the literature. |

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.
