Abstract :Variety of materials with different dielectric constants are available for microstrip patch antenna. In the paper, graphene material is used and analyzed at X-band frequency. The use of graphene patch material as conducting substance for the antenna is assumed to improve the bandwidth and radiation efficiency on account of the outstanding functionalities and  electromagnetic properties. The antenna is designed with Duroid RT5880 insert ignore into journalissuearticles values(lossy); material with a dielectric constant of 2.2 palced between graphene patch and ground plane using Computer Simulation Tool insert ignore into journalissuearticles values(CST); Microwave Studio 2016. The resonance frequency of the antenna is 10.54 GHz with a gain of 7.86dB, return loss of -24.55 dB, directivity of 8.31 dBi and VSWR of 1.1.2. The antenna operates for frequencies from 8 – 12 GHz with an enormous bandwidth of 1.09GHz.
