Abstract: A wireless wearable device, including a housing, a PCB located inside the housing, and an antenna module connected to the PCB. The antenna module is configured to transmit and receive a wireless signal, and includes a first electrode, of which a portion is located at a surface of the housing. The portion of the first electrode keeps in contact with a skin of a user when the wireless wearable device is worn by the user. A total length of the first electrode can be lower a quarter of a wavelength applied in wireless communication. The user does not need to perform an intentional touch or grip due to a constant contact in wearing. A metal housing can be applied without screening transmitted and received signals. Miniaturization of the whole device is achieved while ensuring good quality of wireless communication.

Abstract: A wireless wearable device, including a housing, a PCB located inside the housing, and an antenna module connected to the PCB. The antenna module is configured to transmit and receive a wireless signal, and includes a first electrode. A part of a body of a user and the first electrode together serve as an antenna for the wireless signal. A total length of the first electrode can be lower than a quarter of a wavelength applied in wireless communication. The user does not need to perform an intentional touch or grip due to a constant contact in wearing. Miniaturization of the whole device is achieved while ensuring good quality of wireless communication.
