“…The rapid development of electronic technology has created an urgent problem with regard to light, small electronic materials. Novel electronic devices such as antennae and supercapacitors that are lightweight, compact in size, and simple to manufacture have been replacing traditional single, large pieces of equipment while necessitating the development and production of light, designable materials with expected dielectric properties [1,2].…”

The rapid development of electronic technology has brought convenience and efficiency to the lives of modern people, while emphasizing the need for novel materials with designability and excellent dielectric properties at the same time. In this work, Ti3C2Tx MXene nanosheets (MNSs) underwent NH3·H2O solvothermal treatment at temperatures of 40 °C, 60 °C, 80 °C, 100 °C, 120 °C, 140 °C, 160 °C, and 180 °C. The changes in the surface groups and dielectric properties after the solvothermal treatment were studied. The solvothermal treatment increased the proportion of surface -OH groups, which was beneficial to the permittivity of the MNSs. However, as the treating temperature increased, the amount of -OH on the surface of the MNSs showed a reducing trend, according to XPS spectra. As the treating temperature rose from 40 °C to 80 °C, the real part of the permittivity of MNS sample showed a significant decrease, eventually remaining approximately stable in the 80 °C to 180 °C samples. The results of electromagnetic characterization were in line with the group proportion, as determined via the XPS O1s spectra, supporting the previous conclusion that the -OH group played an important role in the permittivity.

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.
