Patent ID: 8373610

Claim:
An antenna comprising: a ground plane element having portions comprising at least first and second dielectric-filled slots that serve as resonating elements for the antenna and that each have a width of less than 100 microns, wherein the at least first and second dielectric-filled slots are formed in a surface of the ground plane element and wherein the widths of the at least first and second dielectric-filled slots are dimensions of the at least first and second dielectric-filled slots that are coplanar with the surface of the ground plane element; a ground terminal located between the at least first and second dielectric-filled slots and coupled to a ground conductor in a transmission line; and first and second antenna feed terminals coupled to a common signal conductor in the transmission line, wherein the first dielectric-filled slot is between the ground terminal and the first antenna feed terminal and wherein the second dielectric-filled slot is between the ground terminal and the second antenna feed terminal.
