Design and Analysis of Graphene-Based Patch Antenna for WBAN at Terahertz Frequency

In this paper, the graphene-based patch antenna with silicon dioxide substrate is designed and analyzed for WBAN applications operating at the THz band. The dimension of the antenna is 200pm x 180pm x 25.54 pm. Three resonant frequencies are obtained at 6.05 THz, 12.27 THz, and 15.74 THz, with the Sn value of -52.537 dB, -44.568 dB, and — 59.300 dB, respectively. The gains obtained at these frequencies are 8.807 dB, 12.75 dB, 14.17 dB, respectively. This compact and high gain terahertz antenna can be used for WBAN systems, notably for human health tracking applications.
