Patent ID: 8471771

Claim:
A dual-band antenna, comprising: a feed base portion; a low-frequency radiation portion formed by bending a first end of the feed base portion and extended therefrom, wherein the low-frequency radiation portion including: a first transverse portion transversely extended from the first end of the feed base portion; a first longitudinal portion longitudinally extended from a distal end of the first transverse portion; a second transverse portion extended from a distal end of the first longitudinal portion and substantially parallel to the first transverse portion along an identical direction thereof; a second longitudinal portion extended from a distal end of the second transverse portion, substantially parallel to the first longitudinal portion and opposite to the first longitudinal portion; and a third transverse portion extended from a distal end of the second longitudinal portion, parallel to the first transverse portion and opposite to the first and second transverse portions; a high-frequency radiation portion formed by bending a second end of the feed base portion and extended therefrom, wherein the high-frequency radiation portion includes: a third longitudinal portion longitudinally extended from the second end of the feed base portion; a fourth transverse portion transversely extended from a distal end of the third longitudinal portion; and a fourth longitudinal portion extended from a distal end of the fourth transverse portion and substantially parallel to the third longitudinal portion; and a feed end formed by bending the feed base portion and extended therefrom.
