1. A terminal device comprising:
a radiator sharing antenna, comprising:
a radiator comprising:
a first end; and
a second end opposite the first end;
a first ground point located at the first end;
a second ground point located at the second end;
a gap located between the first ground point and the second ground point and dividing the radiator into a first sub-radiator and a second sub-radiator;
a first feeding point located on the first sub-radiator, wherein the first feeding point is configured to pass a first radio frequency signal to generate operating bands through resonance of the first sub-radiator and through parasitic resonance of the second sub-radiator; and
a second feeding point located on the second sub-radiator, wherein the second feeding point is configured to pass a second radio frequency signal to generate additional operating bands through resonance of the second sub-radiator and through parasitic resonance of the first sub-radiator;
a middle frame;
a mainboard disposed on the middle frame, wherein a first space is provided between each of the first sub-radiator and the second sub-radiator and the mainboard; and
a radio frequency front end, disposed on the mainboard, and coupled with the first feeding point and the second feeding point of the radiator sharing antenna.
