ABSTRACT:
A dual-band antenna includes a ground point, a feeding element, a first radiation element, a second radiation element, and an impedance element. The ground point is electronically connected to the first radiation element and the second radiation element. The first radiation element is electronically connected to the feeding element via a first feeding point, and the second radiation element is electronically connected to the feeding element via a second feeding point. The first radiation element includes a head and a neck. A width of the neck decreases from the head toward the first feeding point. The impedance element extends from the neck and through the first feeding point. The dual-band antenna further includes a support element that is connected to the ground point.
