Assignee: BEIJING XIAOMI MOBILE SOFTWARE CO., LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. An antenna radiation method of a mobile terminal, wherein the mobile terminal is a terminal comprising:
a frame having a feed point, wherein the frame defines an outer border of an internal space of the mobile terminal;
a first metal sheet positioned within the internal space, wherein the first metal sheet is coupled to the feed point; and
a second metal sheet positioned within the internal space, wherein the second metal sheet and the first metal sheet have a gap positioned between them, wherein the second metal sheet is coupled to the first metal sheet via the gap;
wherein the second metal sheet comprises a first branch, a second branch, and a connection part, wherein the first branch and the second branch are arranged in parallel and at intervals, wherein the connection part is coupled to a middle of the first branch and a middle of the second branch, wherein the gap is positioned between the first metal sheet and the first branch, and
the method comprises:
providing by the mobile terminal an electrical signal to the feed point;
receiving by the frame the electrical signal, wherein the frame at least forms a resonance of a first frequency band, to radiate an electromagnetic wave; and
receiving by the first metal sheet the electrical signal, to stimulate the electrical signal to the second metal sheet, wherein the second metal sheet forms a resonance of a second frequency band, to radiate an electromagnetic wave.
