Patent ID: 7486242

Claim:
A multiband antenna comprising: a first conducting layer; a second conducting layer; said first conducting layer acting as a radiating element being placed over said second conducting layer; said second conducting layer acting as a ground plane; said first conducting layer comprises a feeding point, wherein said feeding point is a starting point for a first shorter arm and a second longer arm, said first and second arms forming a multilevel structure for said multiband antenna; wherein said first and second arms define a winding path, wherein said second longer arm is folded upon itself to run in parallel with the winding path of said first shorter arm, such that a gap between said first shorter arm and said second longer arm is formed; said gap following substantially the same winding path as said first and second arms on said multilevel structure; and wherein said at least one multilevel structure comprises a conducting structure including a set of polygons, all of said polygons featuring the same number of sides, wherein said polygons are electromagnetically coupled either by means of a capacitive coupling or ohmic contact, wherein a contact region between directly connected polygons is narrower than 50% of a perimeter of said polygons in at least 75% of said polygons defining said conducting multilevel structure.
