ABSTRACT:
A planar antenna. A first plane radiation member, a second plane radiation member, and a third plane radiation member oppose a ground area and provide a first resonant frequency, a second resonant frequency, and a third second resonant frequency, respectively. The first plane radiation member includes a first ground end, a feeding end, and an intermediate portion therebetween. The feeding end inputs signals. The second plane radiation member includes a connecting portion and a first free end extending to one side of the first plane radiation member and separated from the first ground end and feeding end by a first gap. The connecting portion is connected to the intermediate portion. The third plane radiation member includes a second ground end and a third free end surrounding the first and second plane radiation members and separated therefrom by a third gap. The second ground end is connected to the ground area.
