Title:
WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/232994
Kind Code:
A1
Abstract:
Provided is a wearable device, comprising: a metal frame, a printed circuit board (PCB) and a first feeding unit, wherein a gap is formed between the metal frame and the PCB; the metal frame comprises a first feeding point, a first grounding point and a second grounding point; the metal frame is grounded at the first grounding point and the second grounding point; the metal frame is divided into a first area and a second area by means of the first grounding point and the second grounding point; a circumferential length corresponding to the first area is greater than a circumferential length corresponding to the second area; the first feeding point is provided in the first area; the distance, along the metal frame, between the first feeding point and the first grounding point is less than one third of the circumferential length corresponding to the first area; and the first feeding unit performs feeding at the first feeding point. By means of the technical solution provided in the present application, full-band coverage of a 4G communication system can be realized by using a metal frame of a wearable device.
