Modelling and Numerical Investigation of Graphene Assisted SIW Patch Antenna for Different Applications in X-band

A graphene dependent microstrip patch antenna is proposed for X band claims and results are compared with perfect electrical conductor (PEC) rectangular patch antenna. The proposed device is numerically investigated using FDTD tool. The antenna is modelled on “substrate Integrated waveguide” (SIW). The proposed antenna is designed with resonant frequency of 10 GHz and achieved radiation efficiency from input power is 82.4 % with maximum directivity at resonant frequency of 6.73 dB. The device exhibits more than 3 GHz impedance bandwidth with graphene and 900 MHz with PEC as patch material. The proposed designed is compact, light cost effective and easy to fabricate for high directivity and gain.
