Abstract

Terahertz frequency range (from 0.1 THz to 10 THz) which is not fully utilized, has attracted many researchers because of extreme possibility of applications in the unused band. This paper shows the inclusion of graphene with Photonic Band Gap (PBG) in antenna and its effect in the performance of the proposed antenna. The designs, i.e. simple graphene based patch antenna, graphene based slotted ground patch antenna and graphene patch with PBG based antenna in terahertz regime with high gain, high directivity, good impedance matching are proposed here. The proposed antenna shows maximum gain of 5.74 dB and maximum directivity of 6.57 dB. Graphene has been used by many researchers for different applications, including terahertz radiator and terahertz absorber. Here graphene exceptional properties are utilized in terahertz regime antenna for wireless network applications. Good gain and good directivity of the proposed antenna shows better radiation efficiency of the antenna in the THz regime
