| Abstract | An antenna system comprising two closely spaced chip antennas is proposed for dual-band wireless LAN uses. The distance between two chips is 12 mm and the spacing between antenna feeds is 1 mm only. Yet, superior isolation performance is achieved in both operation bands. A novel isolation enhancing measure is implemented for the higher 5 GHz band, which is done by adding a pair of open-ended stubs next to antenna feeds. The stub pair functions as an all-stop filter and elevates the port isolation. Rigorous simulation works were conducted to associate antenna geometry with performance features. Results such as impedance matching, isolation, and radiation patterns were examined jointly to identify mechanisms of its decoupling and diversity features. Antenna diversity assessment measures including the envelope correlation coefficient and the effective diversity gain were derived. Results demonstrate that the proposed compact two-antenna configuration suits well to the diversity antenna need on portable devices. |

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.
