Circular array microstrip antenna embedded in superstrates anisotropic media

In this paper, the effects of anisotropy of Superstrate Anisotropic layers on Circular Patch Array antenna is studied. Circular patch antenna has outer radius of 4 mm and 2.8 mm in depth. The effect of anisotropy properties offers remarkable directivity and gain of Circular Patch. The simulation analysis is performed using CST STUDIO SUITE® software, Matlab Program, and Moment Method (MoM) based solver. The comparison with different anisotropic materials was shown the improvement of performance of Return loss (S-parameters), Axial Ratio, Directivity and gain for Circular Patch Array antenna. The comparison of input impedance for rectangular microstrip patch using our method and a published data are found to be in good agreement.
