Patent attributes
An electronic device includes a dielectric substrate, a first radiation element, a second radiation element, a third radiation element, and a sensing pad. The first radiation element includes a first branch, a second branch, and a first connection element. The first connection element is coupled between the first branch and the second branch. The second branch is coupled to a ground voltage. The second radiation element has a feeding point. The third radiation element is coupled to the feeding point. An antenna structure is formed by the first radiation element, the second radiation element, and the third radiation element. The sensing pad includes a third branch, a fourth branch, and a second connection element. The second connection element is coupled between the third branch and the fourth branch. The second connection element has a meandering structure.
