| Abstract | We present an integrated dielectric resonator antenna (DRA) in a Si-based technology platform for 77 GHz millimeter wave applications. The recent developments in millimeter-wave communications have many challenges from design, fabrication to measurement. The designs usually suffer from high losses and difficulty of circuit integration. Millimeter wave (mmW) antenna can be implemented using different available technologies such as SIW, LTCC, SIIG, and SI-based technology platform. On-chip antennas for 60, 77GHz applications have been reported, however they suffer poor performance with radiation efficiency less than 54% and gain below 3.6 dB. Dielectric resonator antennas (DRA) were intensively developed at low frequencies. Scaling up the frequency to mmW frequencies faces many challenges in the fabrication and appropriate material selection for both RF performance and fabrication technology compatibility. We propose a novel, high gain, high efficiency DRA using Si-based technology platform where all components are fabricated using microfabrication technique at the same time. The technology platform uses high resistivity Si wafers (conductivity = 0.01 s/m). The DRA is excited using coplanar waveguide feed (CPW). Effects of various antenna parameters such as dimensions of the feeder, and the dielectric resonator, thickness of the substrate, and the dielectric resonator on the radiation performance of the antenna are investigated and optimized. The rectangular and half ring DRA antenna gains of 4.72 dB gain with 98% radiation efficiency. |

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.
