Patent ID: 7417588

Claim:
A multi-band monopole antenna, comprising: an antenna substrate; a feeding point; a first conductor for receiving networking signals in the frequency range of about 4.9 GHz to about 5.875 GHz, the first conductor comprising a polygonal portion having a polygonal shape with an aspect ratio of length to width of less than about 5 to about 1; the first conductor further comprising a strip portion having a width smaller than a width of the polygonal portion, a first end of the strip portion is connected to the feeding point, and a second end of the strip portion is connected to the polygonal portion; wherein the polygonal portion comprises at least one notch where conducting material is removed from the polygonal portion for matching the impedance of the antenna; and a second conductor for receiving networking signals in the frequency range of about 2.4 GHz to about 2.5 GHz, the second conductor adopting a linear, space-filling, or grid dimension shape, and having a first end connected to the feeding portion.
