9. A mobile terminal comprising:
a housing and
an antenna disposed in the housing,
wherein the housing comprises a metal frame, the antenna comprises a main stub, a first parasitic stub, and a second parasitic stub, wherein each of the main stub, the first parasitic stub, and the second parasitic stub is a part of the metal frame, wherein
the main stub comprises a first end and a second end, a feed point is disposed between the first end and the second end, a first ground point is disposed on the main stub, and the first ground point is closer to the first end than the second end;
the first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub;
the first parasitic stub comprises a third end and a fourth end, the second parasitic stub comprises a fifth end and a sixth end, the first parasitic stub is coupled to the main stub via a first gap between the second end and the third end, the second parasitic stub is coupled to the main stub via second gap between the first end and the fifth end;
a second ground point is disposed on the first parasitic stub, and is at a location that is between the third end and the fourth end;
a third ground point is disposed on the second parasitic stub, and is at a location that is closer to the fifth end than the sixth end;
a fourth ground point is disposed on a side that is of the second parasitic stub and that is closer to the sixth end than the fifth end;
a fifth ground point is disposed on a side that is of the first parasitic stub and that is closer to the fourth end than the third end; and
wherein a second resonating frequency of the first parasitic stub is greater than a first resonating frequency of the main stub; and a third resonating frequency of the second parasitic stub is less than the first resonating frequency of the resonance excited by the main stub.
