Use of Graphene as a Patch Material in comparison to the copper and other Carbon Nanomaterials

We have designed two patch antennas namely rectangular and circular (FEKO is used as simulation tool).Single-Walled Carbon Nanotube (SWCNT), Multiwalled Carbon Nanotubes (MWCNT), Copper and Graphene are used as patch material. Property of Electrical conductivity is used to differentiate among patch materials. Antenna parameters vary depending on the patch material. Rectangular patch antenna resonates at 2.44 GHz for multiwalled CNT and 2.46 GHz for Carbon and Graphene patch antennas.Simulations results are obtained and compared to analyse the performance of rectangular patch antenna when different patch materials are used. Similar procedure is repeated for Circular Patch Antenna and also for freq 5.8 GHz.By analyzing all the simulated results, it is concluded that Graphene patch antennas show overall excellent performance (by virtue of having higher electrical conductivity) as compared to SWCNT, MWCNT and Copper patch antennas. Copper patch antennas also have good simulated results and performance is slightly less good as compared to Graphene. The reason is that Graphene has slightly higher conductivity than Copper.
