| Abstract | Resonant cavity antennas (RCA) are superstrate based antennas which are capable of enhancing the directivity of simple sources such as dipoles and patches. These antennas have recently received significant research interest from antenna community owing to their simple design, planar nature and highly directive characteristics but narrowband nature. One of the main research goals associated with RCAs is to enhance their half power directivity bandwidth. In this paper, a very simple RCA design is proposed which improves the half power directivity bandwidth almost 74% more than that exhibited by the conventional RCAs. The proposed antenna has a peak directivity of 20dBi with less than ±0.5dB variation over most of the operating bandwidth. The improved bandwidth of the antenna along with stable directivity, consistent beam quality and sufficiently suppressed sidelobe levels make it highly suitable for wireless point-to-point communication links. |

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.
