Patent ID: 8462070

Claim:
An antenna, comprising: a dielectric material having i) a first side opposite a second side, and ii) a conductive via therein; a first planar conducting element on the first side of the dielectric material, the first planar conducting element having an electrical connection to the conductive via; a second planar conducting element on the first side of the dielectric material, wherein the first and second planar conducting elements are separated by a gap that electrically isolates the first planar conducting element from the second planar conducting element; and an electrical microstrip feed line on the second side of the dielectric material, the electrical microstrip feed line electrically connected to the conductive via and having a route extending from the conductive via, to across the gap, to under the second planar conducting element, the route changing direction under the second planar conducting element on the second side of the dielectric material, the second planar conducting element providing a reference plane for both the electrical microstrip feed line and the first planar conducting element; wherein the first planar conducting element has a plurality of electromagnetic radiators, each radiator having dimensions that cause it to resonate over a range of frequencies that differs from a range of frequencies over which an adjacent radiator resonates, and at least first and second of the radiators bounding an open slot in the first planar conducting element, wherein the slot has an orientation perpendicular to the gap.
