Abstract

Antenna is a very important device in telecommunication field used to transmit or receive radio frequency signal. Normally most of the antenna is built up of copper because it is suitable material for it.Recently graphene is claimed as a promising element to replace the copper.Thus,in this project graphene is use as material antenna in designing U-shaped patch antenna with rectangular parasitic patch and PBG structure that generate at 2.4 GHz for WiMAX application.The implementation of design consist the addition of square PBG structure on the ground plane.This method is applied to enhance the gain.This antenna will be design by using FR4 substrate with dielectric constant of Er = 4.4,tangent loss of 0.019 and substrate height of 1.6mm.The coaxial feed will pass through substrate from patch to ground.There are two types of patch material been used; graphene and copper to identify and compare the performance.All the design and simulation will be using Computer Simulation Software (CST).From the simulation,the highest return loss obtained is -24.186dB while gain is 2.252dB and directivity is 2.702dBi.In this project,prove that graphene gives an improvement in the performance of antenna due to its high conductivity.
