Omnidirektionale, dualpolarisierte antenne und kommunikationsvorrichtung

Abstract

This application provides an omnidirectional dual-polarized antenna and a communications device. In this application, the omnidirectional dual-polarized antenna includes a first printed circuit board, a feeding structure, a feeding strip, and grounding strips. A metal ring structure and a metal disc structure are arranged on the first printed circuit board, and the metal ring structure surrounds the metal disc structure. The feeding structure is perpendicular to the first printed circuit board and connected to the metal ring structure. The feeding strip is perpendicular to the first printed circuit board and connected to a central point of the metal disc structure. The grounding strips are each perpendicular to the first printed circuit board and connected to the metal disc structure. The metal ring structure and the feeding structure form a horizontally polarized unit, and the metal disc structure, the feeding strip, and the grounding strips form a vertically polarized unit. In this application, a size of the omnidirectional dual-polarized antenna is reduced, and costs are reduced.
