Claim 0:
1. An antenna structure applied in a wireless communication device, the antenna structure comprising:
a metal frame, the metal frame at least partially made of metal materials, wherein the metal frame defines at least a first gap, a second gap, and a third gap, the third gap being farther from the first gap rather than the second gap, a portion of the metal frame positioned between the first gap and the second gap forms a first radiation portion, a portion of the metal frame between the first gap and the third gap forms a second radiation portion;
a first feed portion, the first feed portion electrically connected to the first radiation portion and a first signal feed point for feeding currents and signals to the first radiation portion;
a second feed portion, the second feed portion spaced apart from the first feed portion, the second feed portion electrically connected to the first radiation portion and a second signal feed point for feeding currents and signals to the first radiation portion;
a third feed portion, the third feed portion electrically connected to the second radiation portion and a third signal feed point for feeding currents and signals to the second radiation portion, the third feed portion electrically connected to a side of the second radiation portion near the third gap;
a ground portion, the ground portion positioned between the first feed portion and the second feed portion, the ground portion electrically connected to the first radiation portion for grounding the first radiation portion; and
an adjusting portion, the adjusting portion being adjacent to the third gap, one end of the adjusting portion electrically connected to the second radiation portion, another end of the adjusting portion is grounded;
wherein when the first feed portion supplies a current, the current flows through the first radiation portion and is grounded through the ground portion, to excite a GPS mode and a WIFI 2.4 GHz mode and generate a radiation signal in a first radiation frequency ban& when the second feed portion supplies a current, the current flows through the first radiation portion and is grounded through the ground portion, to excite a WIFI 5 GHz mode and generate a radiation signal in a second radiation frequency band; a frequency of the WIFI 5 GHz mode is higher than a frequency of the GPS mode and the WIFI 2.4 GHz mode.
