Abstract
The antenna structure is disposed on a heat sink. The heat sink includes a top cover. The antenna structure includes a feeding portion, a grounding portion, and a radiation portion. A vertical projection of the radiation portion is completely overlapped with the top cover of the heat sink. The radiation portion includes a first branch and a second branch. One end of the second branch is vertically connected to the first branch, and another end of the second branch is connected to the feeding portion.
Claims16
An antenna structure disposed on a heat sink, the antenna structure comprising:
- a feeding portion;
- a grounding portion connected to the feeding portion;
- and
- a radiation portion, a vertical projection of the radiation portion being completely overlapped with a top cover of the heat sink, the radiation portion comprising:
- a first branch;
- a second branch, one end of the second branch being vertically connected to the first branch, and another end of the second branch being connected to the feeding portion;
- a third branch, one end of the third branch being vertically connected to one end of the first branch;
- and
