1. An antenna structure, comprising a driven element and at least two parasitic elements, wherein
the at least two parasitic elements are disposed around the driven element and spaced apart from the driven element; and
each parasitic element is provided with a switch control module, wherein the switch control module has at least two switch statuses, and each of the switch statuses of the switch control module corresponds to one electrical length of the parasitic element;
wherein the parasitic elements and the driven element are encapsulated in a columnar structure;
the driven element is located inside the columnar structure; and
some of the at least two parasitic elements are located inside the columnar structure, while other parasitic elements are located on an outer peripheral surface of the columnar structure; or all of the at least two parasitic elements are located on an outer peripheral surface of the columnar structure; or all of the at least two parasitic elements are located inside the columnar structure.
