Microstrip patch antennas can be made from a variety of materials with varying dielectric constants. In this article, a modified multi-slot patch multiband antenna is simulated using CST. Graphene is proposed as a patch material for an antenna that is designed to be used and studied at X and Ku band frequencies. Because of graphene's high conductivity, it is appealing to use it as a conductive patch material to replace copper and other metal conductors while also increasing the antenna's bandwidth and radiation efficiency. On the patch, different sized slot cuts were made. The antenna is made of Duroid RT5880 (lossy) material with a dielectric constant of 2.2 that is sandwiched between a graphene patch and a ground plane. The antenna resonated at 11.22 GHz, indicating that it could be used in the X band frequency range.
