| Abstract | In this paper, the design and simulation of a modified double-ridged antenna is presented (demonstrated). The radiation phenomenon is based on the wave impedance transition from transmission waveguide line to the impedance of free space through ridges. This paper describes the design of an ultrawideband Double Ridged Horn antenna with VSWR less than 2, operating at 5.3GHz to 6.3GHz, 11.02GHz to 11.8GHz, 16.5GHz to 18GHz, 22.8GHz to 23.7GHz and 28GHz to 29.14GHz frequency ranges which are proved to be more suitable as a feed element in reflectors of the RADAR systems and EMC applications. A new coaxial line to double-ridged waveguide transition and a new technique for tapering the flared section of the horn are introduced to improve the return loss and the impedance matching. The ridges are used to lower the cut-off frequency, hence increasing the antenna's bandwidth. An Antenna having coax feed transmission line for radio frequency signal, provides protection of the signal from external electromagnetic interference. To boost the return loss, an external part called “back cavity” is attached to the waveguide. Results of simulation and the performance of a double ridged pyramidal horn antenna in terms of low VSWR (less than 2), high gain, ultra-wide operation frequency bandwidth operating at 5.3GHz to 6.3GHz, 11.02GHz to 11.8GHz, 16.5GHz to 18GHz, 22.8GHz to 23.7GHz and 28GHz to 29.14GHz are provided. The tool used for designing purpose was Ansoft HFSS version 12.0. |

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.
