ABSTRACT:
An antenna system includes interconnected first, second and third saw-like antenna units, each of which is formed by a plurality of metal strips of specific width. An adjacent two of the first metal strips define a first acute angle therebetween. An adjacent two of the second metal strips define a second acute angle smaller than the first acute angle. An adjacent two of the third metal strips define the third acute angle the same as the first acute angle. The second metal strips of the second antenna unit are located densely in such a manner to provide an electromagnetic induction to achieve a second frequency band different from that provided by the first and third antenna units.
