| Abstract | This paper presents a compact composite right/left-handed (CRLH) leaky wave antenna (LWA) composed of 2 × 2 coupled-mushrooms for broadband wireless communications. By optimizing gap widths between the mushrooms, the proposed antenna provides following attractive features; 1) a broadband performance from 6.4 GHz to 10.5 GHz is obtained, which fractional bandwidth corresponds to 49 %. 2) a high radiation efficiency of more than 98 % is attained through the entire operation band. 3) The radiation pattern of the antenna shows a weak directivity, which will be useful for high-speed data communications in mobile use. 4) Since the antenna has a planar structure based on a microstrip line configuration, the conventional print circuit board (PCB) facilities can be used for fabrication, leading to low cost antenna production. The overall dimension of the proposed antenna is 50 mm × 70 mm × 3.2 mm including the antenna substrate. |

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.
