Abstract

An antenna structure for wearable electronic device has a device casing, an antenna ground structure joined with the device casing, a carrier connected to the device casing, and an antenna radiation structure joined with the carrier. Thereby, the antenna structure can be integrated into the original structure of a wearable device so that the volume of the wearable device can be reduced, which solves the difficulty in reducing the volume of a wireless communication device with a requirement of an antenna disposition in the prior art. In addition, a wearable wireless electronic device has the antenna structure so as to have the advantage of smaller volume relative to a wearable wireless electronic device in the prior art.
