Abstract

A multi-band antenna has a strip-shaped first radiating portion disposed levelly. An end of a long side of the first radiating portion is extended downwardly to form a first grounding portion. A strip-shaped second radiating portion is disposed in alignment with and spaced from the first radiating portion. A long side of the second radiating portion is extended downwards to form a feeding portion at an end thereof away from the first radiating portion. A third radiating portion, which is stretched levelly and oppositely from an end of the second radiating portion adjacent to the feeding portion, is longer than the second radiating portion and has a long side extended downwardly to form a fixing portion adjacent to a free end thereof. The feeding portion and the fixing portion are located at the same side as the first grounding portion with respect to the first, second and third radiating portion.
