| Abstract | Reconfigurable antennas have been proposed for mitigating multipath interference and increasing channel capacity in wireless networks. The majority of studies which have investigated these claims do so either in simulation or through the use of software defined radios in lab or office environments. There has been little work in quantifying experimentally the performance gains of a reconfigurable antenna in highly metallic environments representative of military and industrial applications. This letter quantifies the performance gains provided by the use of electrically reconfigurable antennas in the place of omnidirectional antennas given varying environmental and system configurations. Wireless measurements for various 802.11-like physical layers were performed in a set of multideck, coupled compartments aboard Thomas S. Gates (CG 51), a decommissioned Ticonderoga-class U.S. Navy cruiser. The reconfigurable antennas were observed to provide higher channel capacities than omnidirectional antennas. When the bulkhead doors connecting the coupled compartments were left open, the postprocessing signal to noise ratio (PP-SNRs) of signals received from reconfigurable antennas were up to 4 dB higher than what was observed when using omnidirectional antennas. As the compartments became less electrically coupled (i.e., bulkhead doors were closed), the benefit provided via the antenna pattern diversity of the reconfigurable antennas diminished. |

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.
