TWD154663S - Multi-band antenna - Google Patents

Abstract

[Use of the item]; This creation 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 creation]; As shown in the attached figure, the multi-frequency antenna of this creation is formed on a printed circuit board. A base is provided in the middle of the front of the circuit board, and a feeding portion extending downward is connected to the left side of the lower edge of the base. A first connecting portion extending to the left is connected to the upper end of the left edge of the base. A grounding portion that first extends downward, then extends to the right, and then extends downward at the end is connected to the left side of the lower edge of the first connecting portion. A first radiating portion that repeatedly bends downward and extends in a stepped manner is connected to the end edge of the first connecting portion. A second radiating portion extending to the right is connected to the upper end of the right edge of the base. A second connecting portion is connected to the middle of the lower edge of the base, which first extends downward and then bends to the right. A third radiating portion is connected to the terminal edge of the second connecting portion, which first extends to the right, then extends upward, then extends to the left, then extends downward, and finally extends to the left.
