Document Type and Number:
WIPO Patent Application WO/2023/093191
Kind Code:
A1
Abstract:
Provided in the present application are an antenna apparatus and an electronic device. The antenna apparatus comprises a radiator 10, wherein the radiator 10 comprises a grounding point 30 and a feed point 20; the feed point 20 is connected to a feed source, and the radiator 10 generates a plurality of strong current points under the excitation of the feed source; among the plurality of strong current points, a first radiator width corresponding to a first strong current point is less than a second radiator width corresponding to a second strong current point; the first strong current point is a strong current point with the maximum current density, and the second strong current point is any strong current point other than the first strong current point; and the difference between the first radiator width and the second radiator width is used for reducing the maximum current density corresponding to the plurality of strong current points. The antenna apparatus can reduce an SAR value of an antenna, and can easily reduce the SAR of the antenna on an electronic device having a compact structure such as a mobile phone.
