1. An antenna structure, comprising:
a first insulating substrate and a second insulating substrate spaced apart from each other, wherein each of the first insulating substrate and the second insulating substrate has two side surfaces that are opposite to each other;
a first antenna disposed on one of the two side surfaces of the first insulating substrate, wherein the first antenna is in a symmetrical shape and has a first line of symmetry;
a second antenna disposed on another one of the two side surfaces of the first insulating substrate, wherein a geometric center of a region defined by orthogonally projecting the second antenna on the second insulating substrate overlaps a geometric center of a region defined by orthogonally projecting the first antenna on the second insulating substrate, wherein the second antenna is in a symmetrical shape and has a second line of symmetry, and wherein the first line of symmetry and the second line of symmetry have a predetermined angle there-between, and the predetermined angle is within a range from 35 degrees to 55 degrees;
a third antenna disposed on one of the two side surfaces of the second insulating substrate that faces the first insulating substrate;
a grounding element disposed on another one of the two side surfaces of the second insulating substrate away from the first insulating substrate; and
at least one feeding point connected to the third antenna.
