摘要：

We present a metamaterial superstrate based microstrip patch antenna with PIN diode switches applicable for wireless network applications. Metamaterials in the form of square array and circle array are used as superstrate based on microstrip antenna. The superstrate layers are also working as radome and provide strength to the overall structure and improve different antenna parameters like gain and bandwidth. The design results in the form of reflection coefficient (S-11), gain, and bandwidth are compared for different metamaterial superstrate. The reconfiguration in frequency is also achieved by adding PIN diode switches in the metamaterial superstrate. The design results show multiband and high gain behavior for metamaterial superstrate designs. We have also analyzed the effect of using liquid metamaterial superstrate on microstrip antenna design. The design results of liquid metamaterial superstrate design are also compared with copper material superstrate design and simple microstrip patch antenna design. The proposed metamaterial superstrate microstrip antenna design with PIN diodes can become a building block for C/X/Ku-band wireless network devices.
