High Gain Microstrip Patch Antenna based on Fabry Perot Cavity for 5G Communication

In this research work, a high gain Fabry Perot cavity-based microstrip antenna for 5G communication is presented. The proposed work investigated three techniques to achieve high gain. The antenna gain is increased by a perfect electric conductor (PEC) sheet, high dielectric superstrate, and metasurface superstrate. The size of the PEC sheet is kept large to reflect the radiation but it increases the size of the antenna whereas a high dielectric superstrate is not easily available and makes the cost high. The presented work chooses a metasurface superstrate which not only increases the gain, it widens the bandwidth also. Ansys HFSS software is used to simulate the proposed antenna's performance.
