| Abstract | This paper proposes a 60 GHz wideband Yagi-Uda antenna for 2.5 Through Silicon Interposer (TSI) platform. The integrated antenna comprises two parts: a wideband Marchand balun and a differential Yagi-Uda antenna. Marchand balun transfers the balanced signals to un-balanced ones, and subsequently used to feed the differential Yagi-Uda antenna. To achieve wideband, the discussed Marchand balun is realized with the strong broadside coupling between metal layers based on redistributed layer (RDL) technology. Its insertion loss is 3.8 dB, and 15 dB return loss band is from 52 GHz to 74.3 GHz. Phase deviation is consistent and $1–2^{0}$ from the ideal differential outputs. The proposed Yagi-Uda antenna constitutes a half-wavelength dipole as the antenna exciter; the ground plane of rear feeding network is inherently used as inductive reflector. In the front side, a 0.68-wavelength open-circuited stub functions not only as a capacitive director, but also introduces one more resonant mode to widen the antenna operating bandwidth. Lastly, impedance matching from exciter dipole and 100 Ω Marchand balun is realized by the co-planar strip (CPS) line. As a result, a wideband Yagi-Uda antenna on TSI platform with peak 4.7 dBi endfire radiation is successfully achieved, and its fractional bandwidth is 26.0% from 54 GHz to 70.2 GHz. |

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.
