Abstract

[Use of the item]; 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 this invention is formed on a printed circuit board, and a base is provided on the left side of the front of the circuit board. A rectangular feed portion extending to the left is connected to the upper portion of the left edge of the base. A first connecting portion extending upward in a long strip is connected to the upper edge of the base, and a rectangular first radiating portion is connected to the upper edge of the first connecting portion. A second rectangular radiating portion extending to the right is connected to the lower portion of the right edge of the base. A second connecting portion is connected to the upper part of the right side edge of the base, which first extends to the right, then extends upward, and finally extends to the right. A third connecting portion is connected to the lower part of the terminal edge of the second connecting portion, which first extends downward, then extends to the right, then extends upward, and finally extends to the right. A third radiating portion is connected to the upper part of the terminal edge of the third connecting portion, which first extends upward, then extends to the right, and finally extends downward.
