Advantages of graphene technologies in the design of antenna systems for the Internet of Things in the decimeter range of cellular operators (LTE, GSM, 5G)

Abstract

The characteristics and resistance to external influences of flexible graphene antennas are considered. In particular, the analysis of the influence of single and cyclic bends at different cycle times is carried out. Resistance to water of such antennas is analysed. The results of characteristics comparison of the literature data with the results obtained by the authors are presented. The design of a flexible graphene eco-friendly two-layer antenna on a paper substrate operating in the LTE frequency range has been proposed. The technology discussed in this report will help fill the gap in the literature in eco-friendly double-sided graphene printing technologies. The literature review shows that the development of graphene inks for printing on flexible substrates has made a breakthrough in the development of flexible electronics due to their unique advantages. The influence of edge effects on the change in the graphene surface resistance at the edges of the manufactured sample is estimated.
