Abstract

This paper presents the potential of a graphene antenna in the terahertz band for flexible and wearable telecommunication applications. Graphene with its extraordinary electronic properties can be used to fabricate low-profile antennas that provide wearability. Here we investigate the possible resonant frequencies of graphene antenna in the terahertz band by varying the graphene chemical potential from 0.1 eV to 0.4 eV and the relaxation time from 0.1 ps to 0.8 ps. We show that the antenna can resonate at three different frequencies of 4.546 THz, 4.636THz and 5.347 THz. An improved bandwidth at higher chemical potential 0.4 eV observed at 5.5 THz but it is accompanied by a lower directivity compared with the other two resonant frequencies. Moreover, we evaluated the effect of the substrate thickness on surface plasmon polarities (SPPs). Such flexible antennas with a large bandwidth and tunability point to a bright future of terahertz frequency wearable applications.
