1. An antenna structure comprising:
a housing comprising a border frame and a back cover, the border frame and the back cover both made of metal, the border frame surrounding a periphery of the back cover, the back cover comprising a slot, the border frame comprising at least one gap, the slot and the at least one gap cooperatively dividing the border frame into at least two radiating portions;
at least one switching circuit mounted to the at least one gap and electrically connected to the at least two radiating portions on opposite sides of the at least one switching circuit; wherein:
the at least one switching circuit is controlled to switch between an open circuit state and a closed circuit state; and
a length of the at least two radiating portions is changed by the at least one switching circuit being switched between the open circuit state and the closed circuit state to adjust a bandwidth of the antenna structure.
