1. An antenna structure, comprising: a resonant arm, a first feed line portion, a first ground plane, a substrate, a second ground plane, a second feed line portion, and at least two radiation elements, wherein
the resonant arm is electrically connected to the first ground plane through the first feed line portion;
the substrate is attached to the second ground plane, the second ground plane is disposed on a surface of the substrate proximate to the first ground plane, and two ends of a shield layer of the second feed line portion are connected to the first ground plane and the second ground plane, respectively; and
the at least two radiation elements are disposed on a surface of the substrate away from the second ground plane, the second feed line portion wraps a feed line inside, and the feed line passes through the substrate and the second ground plane and electrically connects to the at least two radiation elements; wherein
the shield layer of the second feed line portion is connected to a first end of the second ground plane, and the first end is away from the resonant arm.
