Patent ID: 8780001

Claim:
An asymmetrical dipole antenna, comprising: a substrate; a radiation module, formed by a first metallic conductor arranged on the substrate, and having a radiation base, wherein a first radiation arm and a second radiation arm extend toward a first direction from two ends of the radiation base in an orthogonal manner, the second radiation arm varies from end to end by broad to narrow width and extends toward the first radiation arm and forms an arc opened toward the first radiation arm with the radiation base, and the radiation base comprises a feed point; a ground module, aligned with the radiation module at an interval, formed by a second metallic conductor arranged on the substrate, and having a ground base, wherein a first ground arm and a second ground arm are orthogonal to the ground base, and extend toward a second direction from two ends of the ground base, the second ground arm is a hook and extends toward the first ground arm, a ground point is arranged on the ground base corresponding to the feed point, and a transition portion having an indented notch is formed at a position where the ground base extends to the first ground arm; and a feeder unit, for electrically connecting the feed point and the ground point.
