| Abstract | In this Letter, a reconfigurable half-mode substrate integrated waveguide (HMSIW)-based leaky-wave antenna (LWA) configuration with its edge loaded with the periodic strips is investigated. A good impedance matching is obtained using the loaded configuration. A microstrip line with a tapered-line transition is used to feed the proposed antenna structure. Beam scanning of 24°–66° in the frequency band 9.07–11.04 GHz is achieved with the maximum gain of 14.58 dBi at the frequency 10.07 GHz with a corresponding beam direction of 48°. Thereafter, the edge of the strips is loaded in the middle with variable capacitors connected through narrow stubs to scan the beam at a fixed frequency. The variation in reflection and transmission coefficients, beam angle and antenna gain with variation in the capacitor value for the loaded configuration is investigated. |

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.
