In this letter we propose, for the very first time, a Molybdenum based Yagi‐Uda high‐directional nantenna. It is realized using simple Low Pressure Chemical Vapor Deposition (LPCVD) technique on a silicon substrate for 1550 nm standard optical communication system. The proposed nantenna uses Molybdenum metal as a ground plane while the Yagi‐Uda driven, radiator and directing elements are made up of Aluminum. Grounded Co‐Planar Waveguide (GCPW) technique is used for exciting the nanoantenna in CST Microwave Studio simulator. The nantenna achieves an impedance bandwidth of (193.37–193.71 THz) at a center frequency of 193.5 THz with a high gain and directivity of 12.9 and 16.6 dB, respectively. Near‐field and far‐field performance of the proposed nantenna is also demonstrated via extensive numerical simulations. The results achieved makes the proposed nantenna a viable candidate for applications in the field of nanophotonic circuits and photovoltaic devices working in the optical C‐band window.
