A dual-polarized multiple-input multipleoutput(MIMO)antenna is proposed for 5G base stations. Each antenna element consists of two orthogonally placed fan-shaped dipole elements and ±45°dual-polarized feeding structures are used to achieve broadband operation. The resonant frequency of the array element is from 3. 3 to 4. 2 GHz, which covers the mainstream spectrum allocations of 5G mobile networks. H-shaped coupling elements are used to improve the isolation between the neighboring antenna elem
