| Abstract | A novel design technique to implement dual band substrate integrated waveguide (SIW) cavity backed planar slot antenna is presented. The proposed antenna uses a combination of multiple SIW cavities of different size connected through coupling window in the common sidewall of the cavities. The cavities are loaded with long bow tie shaped slots to achieve higher bandwidth of the antenna. The placement of long bow tie slots helps to generate multiple hybrid modes which can be tuned by varying slot dimensions. First, two SIW cavities loaded with bow-tie slots are used to excite four closely placed hybrid modes in X band (8–12 GHz) to realise dual band response with a bandwidth of 600 MHz (7.2%) and 888 MHz (8.74%) and a gain of 5.3 and 4.4 dBi, respectively. The design is further extended using a set of four SIW cavities arranged as two pair of coupled SIW cavities along with bow-tie slots and placed in orthogonal orientation to implement dual band dual polarised slot antenna while maintaining its planar configuration. The proposed antenna exhibits a bandwidth of 390 MHz (3.9%) and 790 MHz (7.29%) with a gain of 6.1 and 5.4 dBi, respectively. |

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.
