Claim 11:
12. The antenna structure according to claim 11, wherein the first sub-tuning circuit comprises a second switch and a second matching element, and the second sub-tuning circuit comprises a third switch and a third matching element, wherein
when the second switch and the third switch are both in an off state, the antenna radiator generates the first resonant mode;
when the second switch is in an on state and the third switch is in the off state, the antenna radiator generates the second resonant mode;
when the second switch is in the off state and the third switch is in the on state, the antenna radiator generates the third resonant mode; and
when the second switch and the third switch are both in the on state, the antenna radiator generates the fourth resonant mode.
