(54) Miniaturized multi-band antenna


(57) A multi-band antenna (20, 40) includes a bent flat copper antenna forming a radiation surface (S2) to provide GSM-850/900/1800/1900 or GPS multi-band applications, and an auxiliary antenna (28, 48) coupled to the radiation surface (S2) provide WCDMA-2100 / UMTS-2100 multi-band applications. The radiation surface (S2) and the auxiliary antenna (28, 48) are coupled to generate the required bandwidth for multiple radiation bands and to optimize the gain of radiation, so that the multi-band antenna (20, 40) can provide a broad range of services.
