Graphene based Rectangular Wideband Antenna for High Speed and Short Distance Wireless Applications

Proposed wide band terahertz (THz) antenna with partial ground plane incorporating on polyimide substrate material consisting graphene resonant elements for high speed and short distance wireless applications, which operates on the frequency spectrum of 0.45 to 1.73 THz. The antenna is investigated for the multiple electrical parameters such as impedance bandwidth (IBW), voltage standing wave ratio (VSWR), impedance, group delay and gain characteristics. The corresponding IBW, VSWR, fractional bandwidth (FBW) and gain values of the proposed antenna are 1.28 THz, 1.28, 117.43% and 3.62dB, designed within the compact size of $150 \mu m x 150 \mu m x 9.6 \mu m$.
