Abstract
A terminal device includes a radiator sharing antenna. The radiator sharing antenna includes a radiator that is divided into a first sub-radiator and a second sub-radiator through a gap, a first feeding point located on the first sub-radiator, and a second feeding point located on the second sub-radiator. The first feeding point is configured to pass a first radio frequency signal through resonance of the first sub-radiator and through parasitic resonance of the second sub-radiator, and the second feeding point is configured to pass a second radio frequency signal through resonance of the second sub-radiator and through parasitic resonance of the first sub-radiator.
Claims24
A terminal device comprising:
- a radiator sharing antenna, comprising:
- a radiator comprising:
- a first end;
- and
- a second 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, wherein the gap divides the radiator into a first sub-radiator and a second sub-radiator, and wherein the gap provides a capacitive coupling between the first sub-radiator and the 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 through a first resonance of the first sub-radiator and through a first parasitic resonance of the second sub-radiator;
- a second feeding point located on the second sub-radiator, wherein the second feeding point is configured to pass a second radio frequency signal through a second resonance of the second sub-radiator and through a second parasitic resonance of the first sub-radiator;
- a middle frame;
- a mainboard disposed on the middle frame, wherein the mainboard is separated from the first sub-radiator and the second sub-radiator;
- and
- a radio frequency front end disposed on the mainboard and coupled with the first feeding point and the second feeding point.
A radio frequency transmission method comprising:
- providing a gap located between a first ground point and a second ground point of a radiator of a radio sharing antenna, wherein the gap divides the radiator into a first sub-radiator and a second sub-radiator, and wherein the gap provides a capacitive coupling between the first sub-radiator and the second sub-radiator;
- providing a middle frame and a mainboard, wherein the mainboard is disposed on the middle frame, and separated from the first sub-radiator and the second sub-radiator;
- providing a radio frequency front end on the mainboard, the radio frequency front end is coupled with a first feeding point located on the first sub-radiator and a second feeding point located on the second sub-radiator;
- feeding a first radio frequency signal through the first feeding point to the first sub-radiator to generate a first resonance of the first sub-radiator and a first parasitic resonance of the second sub-radiator;
- and
- feeding a second radio frequency signal through the second feeding point to the second sub-radiator to generate a second resonance of the second sub-radiator and a second parasitic resonance of the first sub-radiator.
