ELECTRONIC DEVICE

WIPO Patent Application WO/2021/104005

A1

Provided is an electronic device, comprising a communication module, a system ground plane, a radiator, and an external antenna port, which is electrically connected to a radio-frequency port of the communication module, wherein the radiator comprises a first branch and a second branch, a gap is formed between the first branch and the second branch, the first branch is electrically connected to the radio-frequency port to perform coupling feeding on the second branch, the end of the first branch that is away from the second branch is a feeding end, the end of the second branch that is away from the first branch is a grounding end, and the working frequency band of the radiator comprises low-frequency resonance; the system ground plane comprises an edge portion, which extends along an edge of the system ground plane, and the grounding end is electrically connected to a first position of the edge portion; the external antenna port is mounted on the edge portion; and along an extension path of the edge portion, the distance from the first position to the external antenna port is less than or equal to 1/4λ1 + 1/8λ1 and is greater than or equal to 1/4λ1 - 1/8λ1, and λ1 is the wavelength of the low-frequency resonance. The performance of a low-frequency modal can be improved.
