Abstract

[Use of the article]; This invention is about a multi-frequency antenna, which is assembled inside an electronic product to achieve the reception and transmission of electromagnetic signals by the electronic product. ; [Features of the invention]; As shown in the attached figure, the multi-frequency antenna of the invention is formed on a printed circuit board, and has a base, and a long strip-shaped feeding part and a long strip-shaped grounding part are extended downward from the middle of the lower edge of the base and arranged side by side in a horizontal direction. A rectangular first connecting part extending to the right is connected to the upper right edge of the base, and a long strip-shaped first radiating part extends downward to the right side of the lower end edge of the first connecting part. A long strip-shaped second connecting part extends to the right from the upper right edge of the first connecting part, and a third connecting part in a larger rectangular shape is connected to the end edge of the second connecting part. A second radiating portion in a Z shape is connected to the upper left edge of the third connecting portion, which first extends to the left, then extends upward, and then extends to the left at the end. A third radiating portion in an L shape is connected to the left portion of the upper edge of the base, which first extends upward, then extends to the right.
