<p>Disclosed is a dual-band antenna, comprising an antenna feed point, a feeder line, an antenna radiation unit and a metal ground. The antenna feed point is located at the position where the antenna is connected to a radio frequency circuit; the feeder liner is connected to the antenna radiation unit and the antenna feed point and is used for impedance matching; the antenna radiation unit is used for receiving and radiating electromagnetic waves; the antenna radiation unit comprises a first radiation unit and a second radiation unit which have different resonance frequencies; and the metal ground is a reference ground for the antenna. The bandwidth of the dual-band antenna of the present invention can completely meet the requirements of a dual-band WLAN antenna; in addition, the dual-band antenna has the advantages of low cost, easiness in adjustment of the size, small height and the like.</p> |
