  • Nano optical crescent patch antenna for Terahertz applications using Graphene is designed in this paper. The antenna is designed at 7.28 THZ with several substrates material as PTFE (εr = 2.1), polymide (εr = 3.5), RO3003 (εr = 3), RO4003 (εr = 3.4) and Arlon AD(εr = 2.5). Graphene is the material patch used with different properties such as chemical potential μc = 0.2 eV, relaxation time τ = 1 ps and thickness of 60 nm to achieve a high gain and bandwidth. We obtained a very good performance of crescent antenna at 7.28 THZ with −37.962 dB, 7.124 dBi, 1.767 THZ of return loss, gain and bandwidth respectively which is very satisfactory for terahertz transmisión between [0.1-10] THZ.
