Asymmetrical dipole antenna
First Claim
1. 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.

Abstract
An asymmetrical dipole antenna is provided. A radiation module and a ground module are formed by a metallic conductor and arranged at an interval on a substrate of the antenna, and the radiation module and the ground module, respectively, have a radiation base and a ground base. Two radiation arms and two ground arms are formed by extending from two ends of the two respective bases in opposite directions. The two radiation arms are orthogonal to the radiation base, and the second radiation arm is bent and extended toward the first radiation arm to form an arc opened toward the first radiation arm. The two ground arms are orthogonal to the ground base, and a hook is formed by extending and bending the second ground arm toward the first ground arm. A feeder unit connects the feed point and the ground point of the two bases.
