  • Multi-band antenna assembly
    Publication number: 20090153429
    Abstract: The invention provides a multi-band antenna assembly comprising a connection conductor, a first resonant element, a second resonant element, and a parasitic resonant element. The first resonant element and the second resonant element are electrically connected with the connection conductor respectively. The parasitic resonant element and a grounding part of the connection conductor are grounded. The parasitic resonant element is disposed substantially parallel to the first resonant element, and therein a length of the parasitic resonant element is 15.2 mm˜25.2 mm. The multi-band antenna assembly can provide a working band containing GSM850/GSM900/DCS/PSC/UMTS, even 2.4 GHz or GPS.
