A novel, high-gain reconfigurable antenna with a metasurface (MS) superstrate-based configuration is proposed in this research article. The design utilizes a concentric octagonal-shaped patch as a base antenna. Four SMP1345-079LF PIN diode switches are incorporated in the base antenna to facilitate frequency reconfiguration. When all four of the diodes are in OFF condition, the designed antenna resonates at 5.8 GHz. Switching ON the diodes switches the resonating frequency to 5 GHz. A novel MS unit cell of shape like ‘8’ has been designed and analyzed. The designed unit cell exhibits properties of the metamaterial in the operating frequencies. An MS superstrate of a 5 × 5 array has been designed and connected to the base antenna through Teflon rods. Further, the proposed reconfigurable antenna with MS has been analyzed for air and foam medium (medium between antenna and superstrate). The proposed structure offers better performance for the air medium with a gain enhancement of 4.23 dBi and 1.55 dBi at 5 GHz and 5.8 GHz respectively. Fabrication and testing processes are undertaken to validate the proposed antenna’s performance.
