Patent ID: 8259027

Claim:
A notched radiator comprising: a planar dielectric substrate having a first surface and an oppositely facing second surface; a first conductive layer on the first surface and a second conductive layer on the second surface, wherein the first and second conductive layers are patterned to provide a tapered notch in a first region of the planar dielectric substrate, the tapered notch having a first end and a second end wider than the first end, and the first and second conductive layers patterned to provide a balun in a second region of the planar dielectric substrate, the balun connected with the first end of the tapered notch; and a conductive strip embedded in the planar dielectric substrate between the first and second conductive layers, the conductive strip comprising two different ends configured to transfer differential signals, a portion of the conductive strip intersecting a portion of the tapered notch near the first end.
