Abstract

Antenna, which also called an aerial, is a critical component in wireless communication system that used electromagnetic radiation with an antenna at both transmitting and receiving end. It is a device that is made to efficiently emit and receive radiated electromagnetic waves and ease all the electromagnetic waves that it receive in to free space wave. In this report, the graphene-based Nano patch antenna at microwave frequency have been introduced and presented simulation results for the antenna. Simulation have been done by using CST Software. Besides the fact that graphene material is a moderate conductor at microwave frequency, the graphene can still exhibit sharp resonances frequency at 12 GHz. The simulation clearly demonstrated that the graphene as patch material of Nano antenna gives lowest value of return loss which is -68.55 dB compared with using copper as patch material with -24.79 dB of return loss. A prototype of graphene-based Nano patch antenna were designed on a silicon dielectric substrate with relative dielectric constants of 12.9. An analysis of graphene Nano antennas with rectangular, diamond and elliptical geometries also been presented. The comparison between return loss, gain, radiation efficiency and directivity between those three geometries were tabulated and discussed. The obtained results can be useful to design efficient Nano antenna for microwave wireless communication.
