Patent ID: 7893878

Claim:
An on-chip antenna structure comprises: an antenna element disposed on a first layer of a die, wherein the antenna element has a length in the range of approximately 1¼ millimeters to 2½ millimeters; a ground plane, having a surface area larger than a surface area of the antenna element, disposed on a portion of a surface of a second layer of the die, which surface is directly adjacent to the first layer, wherein the ground plane is substantially parallel to the antenna element from a first axial perspective and wherein the ground plane is substantially co-located to the antenna element from a second axial perspective; and a pair of transmission lines disposed on the first layer of the die and substantially planar with the antenna element, wherein a first line of the pair of transmission lines and a second line of the pair of transmission lines are substantially parallel to each other, and wherein at least the first line is electrically coupled to the antenna element.
