Beschreibung
Zusammenfassung:	A multi-band antenna includes a bent flat copper antenna installed on a surface to provide GSM-850/900/1800/1900 or GPS multi-band applications, and a cylindrical auxiliary antenna installed parallel to the surface provide WCDMA-2100 single band applications. The bent flat copper and the auxiliary antenna are coupled to generate the required bandwidth for multiple radiation bands and to optimize the gain of radiation, so that the multi-band antenna can provide a broad range of services.
