Patent ID: 7443350

Claim:
An antenna, comprising: a planar substrate having first and second opposing substrate surfaces; a first planar radiating element and a second planar radiating element formed on the first surface of the planar substrate; wherein the first planar radiating element has an asymmetrically-shaped pattern comprising a first polygon pattern and an elongated strip pattern extending from the first polygon pattern, wherein the first planar radiating element comprises a first edge that defines a part of the first polygonal pattern and a second edge that defines a part of both the first polygon pattern and the elongated strip pattern; wherein the second planar radiating element has an asymmetrically-shaped pattern comprising a second polygon pattern defined in part by a first edge of the second planar radiating element wherein the first and second planar radiating elements are disposed on the first surface of the planar substrate such that the first edge of the first planar radiating element is adjacent to, and spaced apart from, the first edge of the second planar radiating element.
