| Abstract | In this letter, a novel wide-beam circularly polarized (CP) antenna is presented for satellite digital audio radio service (SDARS) band (2320-2345 MHz), intended for application in portable terminals. This new antenna is comprised of four independent radiation units that are axial symmetrical around the center. The radiation unit is miniaturized by using a distributed capacitive load and a short point in its configuration. The antenna is excited by a compact four-way, quadrifilar power splitter, which is implemented by using microstrip phase shifter and couplers. Simulation results match well with the experimental ones, demonstrating a half-power beamwidth (HPBW) of 120°, a 3-dB axial-ratio beamwidth of 180°, and a good match at 2100-2400 MHz. The developed antenna is based on low-cost printed circuit board (PCB) technique and can be easily integrated with other microwave circuits. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
