For future wireless communication, low-cost, low profile, minimal weight and high performance antenna is required to support high-speed data transmission. This paper presents a graphene based wideband microstrip patch antenna at 1.10THz resonate frequency. Graphene has been used in the proposed antenna for higher electrical conductivity, mobility, and saturation severity in THz band regime. The proposed antenna is mounted on silicon substrate that employed Photonic Band Gap (PBG) having a dielectric constant of 11.9. The outcome of this work has been described in terms of return loss (S11), gain, directivity, voltage standing wave ratio (VSWR) and radiation pattern for both E-plane and H-plane. The proposed antenna has minimal return loss − 48.95dB, gain 3.96dB, VSWR 1.054 and impedance bandwidth 26% which may be an excellent candidate for wireless communication as well as explosive detection, material characterization, medical imaging, homeland defense system etc. All the design and simulations of the proposed antenna has been performed by using commercially available electromagnetic software CST Microwave Studio. |
