Title:
ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/012384
Kind Code:
A1
Abstract:
Embodiments of the present application provide an electronic device, comprising an antenna structure. The antenna structure comprises a first metal radiation patch, a second metal radiation patch, and a feeding unit; the first metal radiation patch comprises a left side edge and a right side edge that are arranged opposite to each other, and a bottom edge connected to the left side edge and the right side edge; a part of the second metal radiation patch is provided in a recess region surrounded by the first metal radiation patch; and the feeding unit performs feeding at a feeding point of the bottom edge offset from a center. According to the technical solutions of the embodiments of the present application, the first metal radiation patch can produce the resonances of two different modes in an asymmetrical feeding manner, and the second metal radiation patch serves as a parasitic patch and can produce another one resonance again, and therefore, the antenna structure provided by the embodiments of the present application can simultaneously product three resonances, thereby effectively broadening the working bandwidth of the antenna structure.
