Communication electronic device and antenna structure thereof

The invention discloses a communication electronic device which comprises an antenna structure. The antenna structure at least comprises a grounding element and an antenna element. The grounding element is provided with a notch at the edge. The antenna element is located at the notch of the grounding element. The antenna element comprises a feed metal part and a short circuit metal part. The feed metal part at least comprises a first section, a second section and a third section. The short circuit metal part comprises a first short circuit section at an open end and a second short circuit section at a short circuit end. A first coupling gap is formed between the first short circuit section and the second section, and a second coupling gap is formed between the second short circuit section and the third section. By the communication electronic device, the distance between a user's hand and an antenna can be increased, and influences, caused by the user's hand, to the antenna can be reduced.
