Patent attributes
An antenna structure comprises a substrate, a first conductive element, a feed point, a first extending element, two first radiation elements, two second radiation elements, a ground element, a signal line, and a ground line. The first conductive element is disposed on the substrate and extends in a first direction. The feed point is connected to an end of the first conductive element. The first extending element is connected to another end of the first conductive element opposite to the feed point and extends in the second direction. The first radiation elements are connected to two ends of the first extending element and extend in the first direction. The second radiation elements are connected to the first extending element, near the first radiation elements and extend in the first direction. The ground element is disposed on the substrate. The signal line is coupled to the feed point. The ground line is coupled to the ground element.
