| Abstract | In this paper, a planar type four-arm rectangular spiral antenna with a novel feeding network is presented. Compared with the Archimedean and log spiral antennas, a planar spiral antenna with rectangular arms has short coming of narrow axial ratio bandwidth. To overcome this weakness, a novel feeding scheme utilizing CRLH metamaterial transmission line is proposed. The network consists of a Wilkinson power divider, metamaterial delay lines, and two half-wave baluns. The measured '10 dB return loss' impedance bandwidth spans over 2.43 GHz from 1.09 GHz to 3.52 GHz. An excellent axial ratio performance (<3dB) over broad band of 1.2 GHz from 1.3 to 2.5 GHz and RHCP gain of 4 dBi over all the frequency band of interest are obtained. |

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.
