Abstract

The invention relates to the technical field of antennas, and particularly relates to a high-isolation omnidirectional array antenna for 5G communication. The high-isolation omnidirectional array antenna comprises a horizontal substrate, wherein the horizontal substrate is a metal grounding plate; an I-shaped gap slot, a U-shaped gap slot and an S-shaped curve gap slot are formed in the horizontal substrate; four dual-frequency antenna elements are also arranged on the horizontal substrate, and are arranged at the end part of the horizontal substrate; and the four dual-frequency antenna elements are arranged in a non-axisymmetric manner. The omnidirectional radiation characteristic can be achieved, 360-degree omnidirectional receiving or transmitting of signals can be achieved, the high-isolation omnidirectional array antenna can be applied to a small base station, and the signal receiving efficiency is improved.
