In this article, a $\mathbf{4}\times \mathbf{4}$ uniformly distributed homogeneous array of subwavelength unit-cell based metasurface backed slotted microstrip patch antennas (MPA) has been proposed to modulate the radiation pattern characteristics and realize polarization diversity. In this proposed dual layer architecture, to analyze the polarization diversification effect on the metasurface layer both the bilinear and orthogonally decomposed surface current vector components have been realized. Achieving circular polarization (CP) in the higher order hybrid or quasi-TEM mode is indicated the orthogonally decomposed surface current vector components through the metasurface. The proposed dual layer metasurface backed MPA architecture can be used in GSM;2.27GHz, WLAN;5.2 GHz and X band;8.78 GHz applications.
