Claim:
1. An antenna, comprising: a coupling portion, comprising a first end and a second end opposite to the first end; a ground connection portion corresponding to the coupling portion, comprising a third end and a fourth end opposite to the third end; and a radiation body, comprising: a first antenna portion extending from the first end in a first direction, a second antenna portion extending from the first end in a second direction opposite to the first direction, and a third antenna portion extending from the third end in a direction surrounding the first antenna portion, wherein two gaps are provided for separating the third antenna portion from the first antenna portion and the second antenna portion respectively; wherein, the first antenna portion comprises: a first horizontal radiation strip, horizontally extending from the first end of the coupling portion in a direction close to the ground connection portion: a first longitudinal radiation strip, vertically extending upward the first horizontal radiation strip; and a second horizontal radiation strip, horizontally extending from the first longitudinal radiation strip in a direction close to the coupling portion; the second antenna portion comprises: a third horizontal radiation strip, extending from the first end in a direction opposite to the first horizontal radiation strip; a second longitudinal radiation strip, vertically extending downward from the third horizontal radiation strip; a fourth horizontal radiation strip, horizontally extending from the second longitudinal radiation strip in a direction away from the coupling portion; a third longitudinal radiation strip, verticality extending upward from the fourth horizontal radiation strip; a fifth horizontal radiation strip, horizontally extending from the third longitudinal radiation strip in a direction away from the coupling portion; and a fourth longitudinal radiation strip vertically extending, upward from the fifth horizontal radiation strip; wherein, the third antenna portion comprises: a sixth horizontal radiation strip, horizontally extending from the ground connection portion in a direction away from coupling portion; a seventh horizontal radiation strip horizontally extending from the sixth horizontal radiation strip; a fifth longitudinal radiation strip vertically extending upward from the seventh horizontal radiation strip; an eighth horizontal radiation strip, horizontally extending from the fifth longitudinal radiation strip toward the fourth longitudinal radiation strip; and a ninth horizontal radiation strip, horizontally extending from the eighth horizontal radiation strip; wherein, the two gaps comprise a second gap between the ninth horizontal radiation strip and the fourth longitudinal radiation strip, for separating the third antenna portion from the second antenna portion.
