Patent ID: 7501991

Claim:
A multiple frequency antenna, comprising: a substrate; a plurality of conductive traces formed on the substrate, one of the plurality of conductive traces forming a radiating portion and another of the plurality of conductive traces forming a ground portion; the radiating portion comprising a radiating portion base having a first base end and a second base end connected by a base body and two radiating arms extending from the radiating portion base, wherein one of the two radiating arms extends from the first base end and forms a space and the other of the two radiating arms extends from the base body into the space; the ground portion being separated from the radiating portion by a gap and comprising a ground portion base having a first ground end and a second ground end connected by a ground body and a plurality of ground arms extending from the ground portion base; and a power feed, the power feed comprising a ground portion aligned substantially parallel with at least a portion of one of the plurality of ground arms and substantially perpendicular to the radiating portion base, and a conductor portion traversing the gap and coupled to the radiating portion base, wherein the antenna operates at multiple frequencies.
