Graphene based Terahertz hybrid plasmonic waveguide fed patch antenna for on-chip wireless applications
Recent growth in Terahertz (THz) communication technology is booming due to the need for high-speed data rates and bandwidth for several wireless application scenarios. In this research, a THz patch antenna is proposed using a hybrid plasmonic THz waveguide-fed structure operating at 3 THz. The hybrid plasmonic waveguide-fed THz patch antenna (HPWTA) is constructed utilising Graphene, Silver (Ag), and Gallium Arsenide (GaAs). Graphene is sandwiched between Ag and GaAs to improve the light confinement. The proposed HPWTA was studied using equivalent circuit and multiphysics simulations to evaluate its mode properties and its on-chip wireless link performance was analyzed using the Finite Difference Time Domain (FDTD) technique. The simulation results demonstrated a high propagation length of 162 μm, high birefringence of 2.6, maximum mode field diameter of 41 µm2, low confinement loss of 1.04 × 10−9 mm−1, high effective mode area of 13.3 µm2, and low anomalous dispersion of 0.23 ps/THz/cm over the frequency range of 2.5 to 3.5 THz. Additionally, the antenna exhibited a high realized gain of 7.9 dBi, 90% efficiency, and a wide bandwidth of 320 GHz at 3 THz, supporting terabit level data transmission for on-chip wireless applications.
