1. An antenna structure, comprising:
a first radiation element, having a feeding point;
a second radiation element, coupled to the feeding point, wherein the second radiation element is at least partially surrounded by the first radiation element;
a third radiation element, coupled to a ground voltage;
a fourth radiation element, coupled to the third radiation element; and
a fifth radiation element, coupled to the third radiation element, wherein the fifth radiation element is at least partially surrounded by the third radiation element and the fourth radiation element;
wherein the antenna structure covers a first frequency band, a second frequency band, a third frequency band, and a fourth frequency band;
wherein a length of the first radiation element is from 0.15 to 0.17 wavelength of the first frequency band;
wherein the second radiation element comprises a terminal bending portion;
wherein a distance between the first radiation element and the terminal bending portion of the second radiation element is from 2.8 mm to 3.3 mm.
