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 (²r = 2.1), polymide (²r = 3.5), RO3003 (²r = 3), RO4003 (²r = 3.4) and Arlon AD (²r = 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 transmission between [0.1-10] THZ.

In this work we designed a rectangular patch antenna in the teraherk band for wireless body network (WBAN) applications using CST software. This antenna is simulated with RO4003C substrate (εr = 3.55) and has dimensions of 199 × 154 μm<sup>2</sup> for width and length, respectively. We obtained return loss of -41.408 dB, -43.918 dB, and -29.92 dB; gain of 5.32 dB, 6.21 dB, and 4.851 Db; directivity of 6.659 dB, 7.502 dB, and 6.566 dB; in 0.74 THZ, 1.148 THZ, and 1.734 THZ frequencies, respectively. The simulation results are very satisfactory, and this antenna can be used for WBAN applications.

In this work, using CST simulation software, we simulated a nano rectangular graphene patch antenna for optical transmission. The chosen dielectric substrate is RT6010 (εr = 3.55) with thickness 2.2 μm. The proposed antenna gives one peak of frequency at 6 THz with return loss of -43.531 dB and a radiation pattern of 5.26 dBi. To improve the performance of the antenna, we simulate the antenna with a relaxation time of 1 ps, 3 ps, and 5 ps. The proposed antenna can be integrated and used for optical transmission.
