| Abstract | A compact two-port diversity antenna is proposed and experimentally investigated. One of the ports is connected to a microstrip feed, whereas the other port to a coplanar waveguide feed. The radiating elements are semi-circular disc-shaped monopoles rotated around their centres. By shaping the common ground plane, ultra-wide impedance bandwidth is achieved. The measured bandwidths are 2–12 GHz at port 1 and 2.3–10.2 GHz at port 2. To obtain good isolation between the ports, a slant inverted tree-shaped structure is attached at the corner of the ground plane. The measured isolation is about 20 dB throughout the band. The antenna has omni-directional radiation patterns with a moderate peak gain of 2–7 dBi. To evaluate the diversity performance, the envelope correlation coefficient, diversity gain and capacity loss are calculated. A modified design with impedance bandwidth at port 2 extending beyond 11 GHz is also presented. The proposed diversity antenna is an attractive candidate to provide polarisation diversity and enhance channel capacity in a rich scattering environment. |

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.
