Abstract

An antenna structure and a mobile device including the same are provided. The mobile includes a metal back cover and an antenna structure. The metal back cover has an open slot. The antenna structure includes a feeding metal radiator, a first grounded metal radiator, a second grounded metal radiator, and a substrate. The feeding metal radiator includes a first radiating portion, a first connecting portion, a second radiating portion and a feeding portion. The first radiating portion extends along a second direction from one side of the opening slot. The second radiating portion is coupled with the first radiating portion through the first connecting portion. The feeding portion is connected to the second radiating portion and extends along the second direction from one side of the open slot.
