Abstract:
1. A multi-band antenna comprising: a coupling portion for feeding-in or feeding-out signals; a first radiation portion coupled to one end of the coupling portion; the first radiation portion bended at one or more bending points to form a plurality of sections, and at least two sections distributed on two planes that are not parallel to each other; and a second radiation portion coupled to another end of the coupling portion; the second radiation portion comprising at least one section, wherein a section of the at least one section of the second radiation portion is parallel to a terminal section of the first radiation portion, has a similar length as the terminal section of the first radiation portion, and is substantially aligned with the terminal section of the first radiation portion in order to have radiation characteristics of the two parallel paralleled sections intercoupled for increasing a bandwidth of the multi-band antenna, wherein the terminal section being a section of the first radiation portion extended furthest from the coupling portion.
