Patent ID: 7675463

Claim:
A monopole antenna, comprising: a dielectric substrate; an antenna feeding point; and an electrically conductive pattern arranged on said dielectric substrate, wherein said conductive pattern comprises a first straight radiating element connected to said antenna feeding point, a second radiating element arranged parallel to, and connected to, said first radiating element, and a third straight radiating element coupled to the second radiating element, the third straight radiating element disposed between and parallel to said first and second radiating elements, and wherein the first, second and third radiating elements are connected such that electric and magnetic fields of said first and said third radiating elements interact constructively, wherein said first and said third radiating elements are spaced apart by a first distance d, and wherein said second and said third radiating elements are spaced apart by a second distance D; wherein each of said first, second and third radiating elements have substantially the same length which is greater than the sum of said first distance d and said second distance D; and wherein each of said first, second and third radiating elements are interconnected by u-shaped interconnecting parts having a continuous curvature.
