Broadband dual-polarized dipole antenna for LTE/5G base station applications.

This article presents a broadband dual-polarized dipole antenna for LTE/5G base station, which consists of loop dipoles, T-shaped cross-feeding lines, L-shaped parasitic elements, and metallic cylinders. As a result, the test results show good achievement of wide band (48.6%, 2.21–3.63 GHz), stable gain (8.3 dBi) and high port-to-port isolation (>30 dB). In addition, good cross-polarization discrimination (XPD) (>30 dB) and stable radiation pattern ( 65.5 ∘ ± 5.5 ∘ ) on horizontal plane are realized over the band by employing a rectangular box-shaped reflector. Furthermore, with simple structure, this antenna can provide partial reference for the design of LTE/5G base station antennas. [ABSTRACT FROM AUTHOR]
