Claim 10:
11. The antenna structure according to claim 1, wherein the first tuning circuit comprises a first sub-tuning circuit and a second sub-tuning circuit connected in parallel, wherein
when the first sub-tuning circuit is in a first working state and the second sub-tuning circuit is in the first working state, the antenna radiator generates a first resonant mode;
when the first sub-tuning circuit is in a second working state and the second sub-tuning circuit is in the first working state, the antenna radiator generates a second resonant mode;
when the first sub-tuning circuit is in the first working state and the second sub-tuning circuit is in the second working state, the antenna radiator generates a third resonant mode; and
when the first sub-tuning circuit is in the second working state and the second sub-tuning circuit is in the second working state, the antenna radiator generates a fourth resonant mode, wherein
resonant frequencies of the first resonant mode, the second resonant mode, the third resonant mode, and the fourth resonant mode are in ascending order.
