DUAL-POLARIZED MILLIMETER-WAVE ANTENNA SYSTEM APPLICABLE TO 5G COMMUNICATIONS AND MOBILE TERMINAL

摘要

A dual-polarized millimeter-wave antenna system applicable to 5G communications and a mobile terminal are disclosed. Each antenna element comprises a radiating body and a director, wherein the radiating body comprises a first dielectric layer, a main radiating part, a first feeding branch, a second feeding branch, a third feeding branch and a fourth branch, and the director comprises a second dielectric layer, a first director part and a second director part. The director has the same effect on a +45° polarization pattern and a −45° polarization pattern of the radiating body, so that wide-angle coverage is realized, and the consistency of the two polarization patterns is good; and the antenna system occupies a small area does not need a clearance area and can be placed on a complete metal ground plate, there by being suitable for full-screen equipment.
