Abstract
In this paper, the parasitic array technique is used to increase the directivity of the rectangular graphene patch antenna. The maximum directivity of the proposed antenna is 9.33 dBi. In this case, a reconfigurable antenna is achieved by considering the tunability of the conductivity of the graphene. Changing the chemical potential of the parasitic array antenna results in the shifting of the operating frequency from 2.35 to 2.7 terahertz. In this design, the main lobe direction of the antenna does not change.
