Abstract

In this paper, the concept of mantle cloaking method uses to enhance the isolation between the two electrically close dipole antenna at low-terahertz (THz) frequencies, two strips of dipole antenna resonating at two different frequencies (2.05 THz and 2.65 THz), and separation between the dipoles antenna is \(0.08{\mathbf{\lambda }}\). We show the reduction of mutual coupling made by wrapping each dipole antenna with a thin graphene monolayer cuboid-shaped structure. The inherent graphene property provides the tuning of surface impedance, leading to the restoration of the matching condition and the antenna radiation pattern.
