A Broadband ±45° Dual-Polarized Multiple-Input Multiple-Output Antenna for 5G Base Stations with Extra Decoupling Elements

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 elements and the mutual coupling is reduced by over 4 dB. The envelope correlation of a 2 × 2 array is provided for verification.
