Title:
OMNIDIRECTIONAL DUAL-POLARIZED ANTENNA AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/087899
Kind Code:
A1
Abstract:
The present application provides an omnidirectional dual-polarized antenna and a communication device. The omnidirectional dual-polarized antenna of the present application comprises: a first printed circuit board (PCB), a feeding structure, a feeding branch, and a grounding branch. The first PCB is provided with a metal annular structure and a metal disk-shaped structure, and the metal annular structure surrounds the metal disk-shaped structure. The feeding structure is provided perpendicular to the first PCB and is connected to the metal annular structure, the feeding branch is provided perpendicular to the first PCB and is connected to a center point of the metal disk-shaped structure, and the grounding branch is provided perpendicular to the first PCB and is connected to the metal disk-shaped structure. The metal annular structure and the feeding structure constitute a horizontal polarization unit, and the metal disk-shaped structure, the feeding branch and the grounding branch constitute a vertical polarization unit. The present application reduces the size of the omnidirectional dual-polarized antenna, and reduces costs.
