Broadband antenna

A broadband antenna, comprising:

• a ground member;
• a first radiation member for providing a first resonance path to make the broadband antenna cover a first frequency band;
• and
• a second radiation member for providing a second resonance path to make the broadband antenna cover a second frequency band, wherein a first end of the second radiation member is directly connected to a first end of the first radiation member to form a first commonly-connected end, the first commonly-connected end has a feed point directly connected to the first end of the first radiation member and the first end of the second radiation member, a second end of the first radiation member is connected to a second end of the second radiation member to form a second commonly-connected end, and the second commonly-connected end is connected to the ground member, wherein a length of the first resonance path is less than a length of the second resonance path, and the first radiation member is surrounded by the second radiation member, wherein a gap enclosed by the first radiation member and the second radiation member is located solely on a first plane and a second plane perpendicular to the first plane.
