N2 - In this paper, an efficient decoupling approach by adopting frequency selective surfaces (FSS) is proposed to solve the mutual coupling problem of dual-polarized antenna array due to the close distance between array elements. Considering the structural symmetry between the dual-polarized antenna elements, the designed FSS is upright placed and symmetrically intersected between adjacent elements to decouple the E-plane and H-plane effectively. Simulation results show that in the operating frequency band of 5G interest of 3.3-3.8 GHz, the isolations of the same polarization elements and orthogonal polarization elements are all enhanced to 20 dB above. At the same time, each port's reflection coefficient and radiation pattern can remain stable. Compared with the tightly arranged dual-polarized antenna that has very limited design freedom in terms of physical space, the proposed decoupling approach has a significant effect and has promising merit in 5G applications.
