A 5G MMW dual-polarized antenna module includes a substrate. A metal ground and an antenna unit group are disposed in the substrate. The metal ground partitions the substrate into a first region and a second region. The antenna unit group includes a first antenna unit, a patch antenna and a probe. The first antenna unit includes a first branch and a second branch connected to the first branch, wherein the first branch is disposed in the first region, and an end, away from the first branch, of the second branch is located in the second region. The probe includes a first part and a second part connected to the first part, wherein the second part is disposed in the first region. The MMW dual-polarized antenna module can fulfill lateral radiation in light and thin terminal devices.
