1. An antenna structure applied in a wireless communication device, the wireless communication device comprising a hinge, the antenna structure comprising:
a feed portion;
a first radiation portion, an end of the first radiation portion electrically connected to the feed portion, another end of the first radiation portion spaced from the hinge with a first gap; and
at least one ground portion;
wherein the antenna structure generates a radiation signal in at least one radiation frequency band when the feed portion feeds electrical current to the first radiation portion and the hinge couples the electrical current from the first radiation portion;
the first radiation portion comprises a first radiation section, a second radiation section, a third radiation section, and a fourth radiation section connected in order; the first radiation section and the third radiation section are perpendicularly connected to two ends of the second radiation section and extend in opposite directions; one end of the first radiation section is electrically connected to a feed power source through the feed portion; the fourth radiation section is perpendicularly connected to an end of the third radiation section that away from the second radiation section, the fourth radiation section is parallel with the second radiation section, the fourth radiation section and the second radiation section extend in a same direction from two ends of the third radiation section; the fourth radiation section is parallel with and spaced apart from the hinge with the first gap; a length of the fourth radiation section is greater than a length of the second radiation section.
