Abstract
A multi-band antenna includes a bent flat copper antenna forming a radiation surface to provide GSM-850/900/1800/1900 or GPS multi-band applications, and an auxiliary antenna coupled to the radiation surface provide WCDMA-2100/UMTS-2100 multi-band applications. The radiation surface 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.

A multi-band antenna comprising:
- a coupling portion installed on a first surface for feeding-in or feeding-out signals;
- a first radiation portion installed on a second surface crossing the first surface and coupled to the coupling portion, the first radiation portion comprising at least one section;
- a second radiation portion installed on the second surface and coupled to the coupling portion, the second radiation portion comprising at least one section, wherein one section of the second radiation portion is parallel to one section of the first radiation portion and has an intercoupling with the first radiation portion;
- and
- a third radiation portion installed on the first surface and coupled to the coupling portion, the third radiation portion having an intercoupling with the first radiation portion and second radiation portion.
