TWD154666S - 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, and a rectangular first grounding portion is provided on the left side of the front of the circuit board, and a first extension portion extends to the right from the lower end of the right edge of the first grounding portion. A first feed portion in the shape of a long strip extending laterally is provided on the right side of the first grounding portion in front of the circuit board, and a first radiating portion is connected to the right side of the lower edge of the first feed portion. The first radiating portion has a first bending portion that first extends downward, then extends to the left, and then extends upward, and the terminal edge of the first bending portion is connected to a second bending portion that first extends to the right, then extends downward, and finally extends to the left. A rectangular second grounding portion is provided on the right side of the front of the circuit board, and a second extension portion extending first to the left and then downward is connected to the middle of the left edge of the second grounding portion. A second rectangular feeding portion extending horizontally is provided above the left side of the second grounding portion on the front of the circuit board, and a second radiating portion extending first downward and then to the left is connected to the middle of the lower edge of the second feeding portion.
