1. An antenna structure for transmitting a wireless signal, comprising:
a substrate;
a first conductive element, disposed on the substrate and extending in a first direction;
a feed point, connected to an end of the first conductive element;
a first extending element, connected to another end of the first conductive element opposite to the feed point, and extending in a second direction perpendicular to the first direction;
two first radiation elements, connected to two ends of the first extending element and extending in the first direction;
two second radiation elements, connected to the first extending element, near the first radiation elements and extending in the first direction;
a ground element, disposed on the substrate;
two first L-shaped elements, separately connected to the first extending element and electrically connected to the ground element;
a signal line, electrically connected to the feed point; and
a ground line, electrically connected to the ground element.
