Performance comparison of graphene terahertz antenna and copper terahertz antenna

Abstract

Terahertz frequency, also called terahertz gap, ranges from 0.1 to 10 THz is the area of the most up-to-date research spectrum useful for wireless communication. In this paper, performance of terahertz antenna using graphene and copper patch are analyzed. MATLAB codes are used to characterize the properties of graphene and are applied to high-frequency electromagnetic software which is used for modeling and simulation of the proposed antenna. Paper highlights the use of counterpart of copper, i.e. graphene as a patch material in terahertz antenna and also shows the performance comparison of graphene-based terahertz antenna and copper-based terahertz antenna. Return loss, directivity, and gain of the proposed antenna are compared. Results analysis shows that graphene is better option for the design of terahertz antenna.
