Abstract
A 5G MMW dual-polarized antenna unit, an antenna array and a terminal device are disclosed. The 5G MMW dual-polarized antenna unit comprises a substrate and two feeder assemblies disposed in the substrate, wherein a square radiation patch conductive with the feeder assemblies is disposed on a top surface of the substrate, and a ground layer and feeder ports conductive with the feeder assemblies are disposed on a bottom surface of the substrate; each feeder assembly comprises an impedance transformation micro-strip line, and the two impedance transformation micro-strip lines are perpendicular to each other; and a short-circuit structure allowing the radiation patch to be conductive with the ground layer is disposed in the substrate and is located an intersection of extension lines of the two impedance transformation micro-strip lines. The 5G MMW dual-polarized antenna unit effectively improves the antenna performance and satisfies application requirements of 5G communication terminals in this waveband.
