Abstract (en)

[origin: WO9922420A1] A multiple band antenna having multiple branches, each branch having a length and geometry selected to resonate in a particular frequency band. Each branch can be formed by a flexible film which has a meandering strip line pattern formed thereon and which is formed into a desired shape. Each branch can also be formed by etching a strip line to a member of a desired shape. The strip line pattern is preferably formed by printing so as to avoid mechanical tolerance problems.
