| Abstract | A central feeding array radiating at broadside and manufactured in substrate-integrated waveguide (SIW) technology is shown in this work. The single-layer array consists of N = 8 line-source leaky-wave antennas (LWAs), which are designed to satisfy the splitting condition (α = β) of the leaky mode. The LWAs are arranged in a radial configuration, in this manner, by properly designing the SIW width W and the spacing between SIW vias P for each SIW LWA, the leaky mode can be independently controlled to fulfil the splitting condition, and all the individual beams from each SIW LWA can merge into one at broadside direction (θ = 0°) for a given design frequency. The two-dimensional radiating surface allows obtaining a pencil beam radiation pattern, which is linearly polarised because of the radial arrangement. A prototype with a radiating length of L A = 60 mm for each SIW LWA, and a total radius of R = 73 mm has been manufactured for a design frequency of 15 GHz. Input matching, gain and radiation patterns at several planes have been measured and compared with full-wave simulations, obtaining good agreement between them. |

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.
