Patent ID: 7180463

Claim:
A dual-band antenna printed on a substrate for radiating radio frequency signals, the dual-band antenna comprising: a feeding element; a first feeding point electronically connected to the feeding element; a second feeding point electronically connected to the feeding element; a first radiating element for radiating first radio frequency signals, the first radiating element comprising a head and a neck, the neck having two ends, one of the ends being connected to the head, and the other end being electronically connected to the feeding element by way of the first feeding point, a width of the neck gradually decreasing from the head to the first feeding point; a second radiating element electronically connected to the feeding element by way of the second feeding point, for radiating second radio frequency signals; an impedance element electronically connected to the first radiating element by way of the first feeding point; and a ground point electronically connected to the first feeding point and the second feeding point.
