Dual polarization, dual band and miniaturized 5G mobile antenna is realized by combining basic 1x4 patch array (Broadside) and 1x4 dipole array (End-fire). Broadside uses Reactive Impedance Surface (RIS) and end-fire uses vertically folded dipole antenna to maximize gain and bandwidth performance. Additionally, the antenna's performance is improved by using a very small and thin metasurface that can be mounted on a smartphone. Inserting this metasurface directly under the antenna and smartphone case improves the beam coverage of the smartphone in the 5G/6G band. Since the inserted metasurface, antenna, and smartphone case are designed to be combined from the initial stage, the radiation performance of the smartphone can be maximized.
