| Abstract | A novel Ka-band composite circularly polarized dielectric complex waveguide slot (CP-DCWS) antenna array is designed, fabricated and measured. The CP-DCWS antenna array is composed of a circular polarization grid, a slot microstrip line, a groove guide and feeding network. The slot microstrip line is formed by a metal clad dielectric substrate and slots etched in the metal. This antenna array not only maintains the advantages of the traditional waveguide slot antenna array, but also has the characteristics of wide bandwidth. The measurements show that the radiating efficiency of the CP-DCWS antenna array is 80%, which is almost the same as the traditional waveguide slot antenna array, and the bandwidth of the CP-DCWS antenna array is 700 MHz, which is 200 MHz (40%) wider than the traditional waveguide slot array antenna. Measured results are in good agreement with electromagnetic simulations. |

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.
