1. An antenna comprising:
a radiator; and
a balun structure coupled to the radiator and configured to feed the radiator, wherein the balun structure has a U-shaped structure and comprises:
a first side; and
a second side located opposite to the first side,
wherein the radiator comprises:
a first branch for a first current to flow through and arranged on the first side, wherein the first current flows in a first direction, wherein the first branch is spaced from the balun structure by a first slot, and wherein the first slot is configured to form a first horizontally-radiated electric field in a second direction based on the first current and a third current on the balun structure, wherein the first direction is perpendicular to the second direction; and
a second branch for a second current to flow through and arranged on the second side, wherein the second current flows in the first direction, wherein the second branch is spaced from the balun structure by a second slot, and wherein the second slot is configured to form a second horizontally-radiated electric field in the second direction based on the second current and the third current,
wherein the balun structure further comprises:
a first strip-shaped structure coupled to the first branch, wherein the first slot is formed between the first branch and the first strip-shaped structure; and
a second strip-shaped structure coupled to the second branch, wherein the second slot is formed between the second branch and the second strip-shaped structure,
wherein a first width of the first slot ranges from 0.5 millimeters (mm) to 4 mm, wherein a second width of the second slot ranges from 0.5 mm to 4 mm, wherein the width of the first slot is smaller than a width of the first branch, and wherein the width of the second slot is smaller than a width of the second branch, wherein a width of each of the first branch and the second branch ranges from 1 mm to 4 mm.
