Title:
ANTENNA ASSEMBLY AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/206237
Kind Code:
A1
Abstract:
Provided are an antenna assembly and an electronic device. A first antenna unit comprises a first radiator, a grounding branch and a first signal source, wherein the first radiator comprises a first radiation branch and a second radiation branch, and the connection position between the first radiation branch and the second radiation branch is a first feed point; one end of the grounding branch is electrically connected to the first feed point, and the other end of the grounding branch is electrically connected to a reference ground; and the first signal source is electrically connected to the first feed point, and is used for exciting the first radiation branch and the second radiation branch to respectively resonate in a first wavelength mode of a first frequency band. A second antenna unit comprises a second radiator, a second signal source and the first radiator, wherein there is a coupling gap between the second radiator and the first radiator, the second signal source is electrically connected to the second radiator, and the second signal source is used for exciting the second radiator to resonate in a first wavelength mode of a second frequency band, and exciting, by means of the coupling gap, the first radiator to resonate in a second wavelength mode of the second frequency band. By means of the present application, the antenna efficiency can be improved.
