“…It consists in depositing a thin layer of graphene on a substrate by means of a chemical reaction. To produce high quality graphene with desired properties, it is necessary to carefully control the chemical potential by adjusting the temperature, gas pressure and other factors in the CVD process [4,5].…”

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.

This study presents a design for a frequency-reconfigurable pentagonal patch antenna for wireless networks, operating at 10 different frequencies by utilizing the switching states of PIN diodes. The size of our proposed antenna is 26.31 × 20.24 × 1.5 mm<sup>3</sup>. The insertion of four PIN diodes in the patch offers frequencies of 3.5 and 5.81 GHz in M1 mode, 2.438, 5.855, and 7.805 GHz in M2 mode, 2.715, 4.775, and 6.305 GHz in M3 mode, and 4.7375 and 6.2975 GHz in M4 mode. Therefore, the suggested design accommodates various applications as well as 4G/5G bands, WiFi, WiFi 6E, ISM band, radar, radio relay systems and communication systems, etc. This design shows good return loss across all resonant frequencies. Additionally, the structure shows satisfactory performance in terms of gain, directivity, VSWR, and bandwidth.
