An antenna comprises a first pad, a second pad, a radiating element, a meandering element, and a third pad disposed in an antenna region on a circuit board. The first pad and the second pad are spaced apart and disposed at opposite ends of the antenna region. The radiating element is disposed between the first pad and the second pad and is capacitively coupled to the first pad. The meandering element is connected to the radiating element at a position adjacent the first pad. The meandering element extends in the first direction away from the first pad while meandering reciprocally in the second direction. The third pad is capacitively coupled to the second pad.
