Graphene based different types of slotted antennas have been designed and compared with respect to slot position, return Loss, voltage standing wave ratio, bandwidth and radiation pattern. Different patch materials, patch shapes, position and inclination of slots in these antennas can alter their performance. This paper comprises with the performance comparison of different shaped microstrip patch antennas i.e. H shape, E shape, Z shape, L shape, T shape and P shape using CST Microwave Studio Suite to operate in the frequency limit of 2.6 GHz to 4 GHz. Among these antennas P-shaped antenna has better performance than others with both copper and graphene patch materials.
